Bulletproof Fat Bombs

These Bulletproof Fat Bombs taste like frozen creamy mocha smoothie. A creamy low-carb dessert for all coffee lovers!

Add a splash of rum or rum extract and they resemble Tiramisu. In fact, I created this recipe while I was working on a keto-friendly Tiramisu for my KetoDiet Cookbook! It includes some of the best 150 low-carb, paleo / primal recipes created exclusively for the cookbook!

These sugar-free treats are ideal for the fat fast and healthy low-carb snacking. Just remember, all fat bombs are treats, not meal replacements — you should eat them in moderation, no more than 1-2 pieces at a time.

How To Make Frozen Fat Bombs

To make the smooth coffee cream mixture, I'm using my Kenwood mixer with a blender attachment.

You can use any ice cream maker. I use Cuisinart) with a built-in freezer but there are less expensive alternatives you can use.

If you don't have an ice-cream maker, pour the mixture directly into an ice tray or small muffin tin. You should be able to fit ~ 2 tablespoons per fat bomb or make smaller fat bombs. You can also use 1-2 teaspoons instant coffee powder instead of ¹/₂ cup of coffee. The mixture will be thicker and you won't need an ice-cream maker.

To make the round shapes, I used this Ball Shaped Lollypop Tray) which is great for making fat bombs. I used the same one in my Strawberry Cheesecake Fat Bombs.

Ingredients (makes 20 fat bombs)

1 cup creamed coconut milk or mascarpone cheese or full-fat cream cheese (250 g/ 8.8 oz)
¹/₄ cup butter or extra virgin coconut oil (56 g/ 2 oz)
2 tbsp MCT oil or Brain Octane Oil or more coconut oil (30 ml)
2 tbsp cacao powder or Dutch process cocoa powder (11 g/ 0.4 oz)
¹/₄ cup powdered Erythritol or Swerve (40 g/ 1.4 oz)
10-15 drops liquid Stevia extract, or to taste
¹/₂ cup strong brewed coffee or caffeine-free chicory coffee (120 ml/ 4 fl oz)
Optional: 1 tsp sugar-free rum extract or 2-4 tbsp dark rum

Instructions

Place the softened creamed coconut milk (or mascarpone cheese), butter or coconut oil, MCT oil and cocoa powder. Optionally, add the rum extract
Add powdered Erythritol and stevia into a blender and pulse until smooth.
Pour in the prepared coffee (room temperature or lukewarm, not hot) and pulse again until smooth. Pour into the into the ice-cream maker and process according to the manufacturer's instructions. It may take anything between 30-60 minutes depending on your ice-cream maker. Using an ice-cream maker makes the texture smoother & creamy and also allows me to form the "bomb" shapes.
Spoon about 2 tablespoons of the ice-cream into ice tray.
Place in the freezer for 2-3 hours or until firm.
Enjoy! Store in the freezer for up to 3 months.

Apparently, it’s Chrome. I cut and pasted the url into Safari and the optimized version came up. Thanks!

Thank you Jehna, that helps, we'll look into it!

Are you aware that the print button prints the entire post, not just the recipe? That’s an incredible waste of paper! Please fix this. Thanks!

Martina @ KetoDiet 6 months ago #

Hi Jehna, the purple button on our website only prints an optimised version of this recipe (not the whole post, just essential info including ingredients, recipe steps, nutrition facts and time to prepare + a small image of the photo in the corner) - maybe it was on another blog blog?

I’m on my iPad Air 2, so I don’t know if that has anything to do with it, but I am using the purple button and the entire post comes up in my printer preview. I took a screenshot, but I don’t know how to attach it. It’s from the top of the page, all the way to the bottom with all the steps, including pictures and ads.

This is a really great fat bomb, creamy, filling, smooth. Mmm.
Something that I tried was to make a "concentrate" of sorts. I added all the ingredients except the butter and extra coconut oil to a jar (used coconut milk) and shook it until combined. Then, i would pour some almond milk into a coffee cup, add some butter, add some mix from the jar, and then warm in the microwave. It makes a really good hot mocha latte 😊
I generally have trouble getting enough fat in my diet, and I love coffee, so I thought "fat bomb coffee? Yes please".

Martina @ KetoDiet 7 months ago #

That sounds so good, it must be super creamy too!

MaidMirawyn (https://mirawyncrafts.blogspot.com/) 10 months ago #

This looks amazing!
One question...what do you mean by "creamed" coconut milk? I know what coconut cream is, but you linked to coconut milk on Amazon, so I know it can't be that.
I definitely want to try these with the rum extract, to make the faux tiramisu. Thanks.

Martina @ KetoDiet 9 months ago #

That should be the same. Coconut cream (store bought) may be a little more runny as it may contain some of the liquid). Creamed coconut milk is only the solid part in the coconut milk can after leaving the can in the fridge overnight. I hope this helps!

I read through all the comments on the bulletproof fat bombs and didnt see this anywhere. Could these be used in making my bpc every morning. This way instead of measuring my ingredients put every day I could just drop one of these in straight from the freezer? I already use coffee ice cubes to cool off my coffee so I can drink it so it would be 2 birds with 1 bomb.

That's an interesting idea! I think these could be great for iced bulletproof coffee if you blend it with cold coffee! 😊

Jenny one year ago #

I am allergic to chocolate so I can’t put the cocoa powder in, Will the consistency be ok without it? Or is there something else you suggest substituting?

Martina @ KetoDiet one year ago #

You could try carob powder or leave it out. It may be a bit thinner but you could always freeze it in small popsicle molds instead 😊

Tammy one year ago #

This made exactly 20 servings of ONE tablespoon for me, which was just fine. The only ingredient I had to downsize was my cream cheese; I did 227g instead of 250g. And I just mixed the ingredients with a plain ol' spoon. It still turned out velvety smooth (so they just didn't have that "whipped" factor). I think they are sooo good, but my sister finds they are too strong of coffee flavour (I used 2 tsp espresso powder + a bit of water). Also, I didn't have any liquid Stevia, so I just did without it. Delicious!! It's like the coffee icing off the best coffee cake I ever ate without the extra sweetness. I look forward to trying it with marscapone next time. 😊

Thank you Tammy! ❤

At what point do you add the rum for the tiramisu flavor?

Martina @ KetoDiet 11 months ago #

Hi Amber, just updated to clarify (please see step 1) 😊

Jill one year ago #

Since I don't have an ice cream maker or a conventional blender, what can I use to blend? I have a Ninja processor and a KitchenAid full size processor.

Ninja will work just fine! If you don't have an ice cream maker, you can use regular ice cube tray (and skip the churning).

Shelly one year ago #

I don’t know what I did wrong but mine turned out SO salty!!! I’ll attempt them one more time. Otherwise they would be delish!

Hi Shelly, could it be the butter? Maybe it wasn't unsalted?

Emily 2 years ago #

Can you make this without using the ice cream maker? I don't have one.. but these look amazing!!

Martina @ KetoDiet 2 years ago #

You definitely can! But it will be better to use mini popsicle molds instead of the ones I used.

Valorie 3 years ago #

If all I have is the powdered swerve how much of that should I use instead of adding the 10 or 15 Stevia drops. Otherwise how much altogether should I use in this recipe if all I have is the powdered swerve thank you so much

Martina @ KetoDiet 3 years ago #

Hi Valorie, this depends on your palate. I'd start with just the 1/4 cup Erythritol or Swerve and add 1-3 more tablespoons if needed. Also, I use Erythritol which not as sweet as Swerve, so 1/4 cup Swerve may be enough.

Cheryl 2 years ago #

You could also use a splash of sugar free coffee syrup. I just made some using sugar free Carmel and it is awesome from the taste I had. I used cupcake papers because I don't have a working ice cream maker at the moment.

Ada Nilda Bren one year ago #

I used one pk which was 2 tsp, if you want it sweeter than use 2pk

gena sterling 3 years ago #

what using tea instead of coffee... coffee my stomach just can't stand coffee.

Yes, you can use tea instead... Ideally black but it depends on your palate - some people use herbal tea to make BPC 😊

Sam B 3 years ago #

I tried these and they turned out great. They must be kept in the freezer since they will melt in the fridge. I first used ice trays to make them, but those pieces were too big. I let them melt down enough to put into smaller molds and now they're the perfect bite size pieces. Taste great and melts in your mouth!

Awesome, I'm glad you liked them! 😊

Deb T 3 years ago #

How important is it to add ANY of the "sweeteners"? So many recipes use stevia or other suitable sweetener... I don't like sweets ..I drink black coffee, eat 90% chocolate.. Can I just leave it out?
Thank you!

Of course! I actually prefer this recipe without sweeteners because I never put them in my coffee 😊

Jennifer 4 years ago #

I see where stevia has been left out, but is it possible to only use 1/4 C unfiltered organic honey or maple syrup and add no other sweeteners. I only use those and sometimes coconut sugar due to autoimmune issues.

Martina @ KetoDiet 4 years ago #

Hi Jennifer, absolutely - if you can tolerate more carbs, you can use these paleo-friendly options!

Clarke (http://www.1hourathlete.com/) 4 years ago #

These look delicious - I've been looking for a low carb snack to take to work! 😊

I'm not sure these are suitable for work - they will melt on the way there 😊 You can try any of these that don't require freezing: ketodietapp.com/Blog/Filter

Melanie 4 years ago #

I am wondering if you can recommend something other than liquid Stevia. I am allergic to Stevia.

Hi Melanie, you can skip the stevia or add more Erythritol instead (to taste).

Jessica 4 years ago #

Hi Martina! I love this idea & so want to make these turn out right.... but something seems very wrong. I have all ingredients mixed together ready to go in the ice cream maker & all I have is a big blob of brown cottage cheese. Yours looked like a liguid. I reread the recipe several times & I did use the marscapone cheese. HELP! What have I done wrong? The flavor tastes great but the consistency seems way off. Thanks so much.

I'm sorry about that Jessica, it looks like it has curdled. I'm not sure but it must be the temperature of the ingredients. Does it curdle before or after adding the coffee? And sorry about the late reply!

then what do you do with the bombs, how would i use this in my ketopia diet? ty new to all this

Hi Tammy, here are the reasons for including fat bombs: Bacon & Guacamole Fat Bombs Hope this helps! 😊

Lib 4 years ago #

I made these last night, and they turned out pretty good. I didn't have any eryth on hand so I used all Stevia. Kinda bitter but that's my fault. The texture was great. I used Starbucks instant coffee- without an ice cream maker. I also used my daughter's fish shaped ice cube trays. Made for a funny presentation. I can't wait to do it "right' next time. I have no doubt the results will be fantastic.

I have to admit that I actually like them sweetener-free but that may be just me because I don't use any sweeteners in my coffee. Hope you like the next batch! 😊

Steph 4 years ago #

I made these and the flavor is excellent. I used the mascarpone/butter/coconut oil method and did not add the Stevia drops. I used a regular blender and when I mixed everything it made the most wonderful mousse which would make a great dessert by itself! I didn't need the ice cream maker at all even though I have one. Delicious!

Awesome! Glad you liked them! 😊

Helen 4 years ago #

You said you didn't use the Stevia drops but did you still sweeten with the ¼ cup Erythritol or Swerve? Thank you

Kelly 4 years ago #

So I froze my coffee into ice cubes and added to my Vitamix. It made a nice thick creamy mixture that I could spoon into a mini muffin pan. My hubby was eating straight out of the blender jar. I'm looking forward to trying them when they freeze.

Great idea to use frozen coffee cubes! 😊

These are amazing! Thank you for sharing this recipe. I used a mini silicone tray (got 24 pieces), popped them out and into a freezer bag! Perfect size treat.

Glad you liked them Michelle! 😊

Lani 4 years ago #

Hi, Martina! I've been looking for coffee fat bombs for ages and these look beautiful! I usually take my coffee without sweetener, but I do want to lightly sweeten these. However, all I have is liquid Stevia drops. Could I simply use the 10-15 drops and avoid the powdered sweetener altogether? Would the structure hold up? Thanks!

Hi Lani, thank you! Yes, you can use just stevia. Try 10-15 drops and add more if needed. The structure will not be affected.

Kimsigns2 4 years ago #

i don't understand the purpose of the ice cream maker. If you don't need it, why is it in the recipe? What does the ice cream maker do different than if you don't use it? Thanks, Kim

Hi Kim, the reason I used an ice-cream maker it to be able to create the "bomb" shapes and it also makes the ice-cream smooth. But no, yu don't need to use it. I'll add some more tips in the post:
- using popsicle molds if you don't want to use an ice-cream maker
- or coffee powder instead of 1/2 cup coffee so that the mixture is thicker and easier to form into "bombs"

Jinxx 4 years ago #

Do you know anything about great values stevia? Is it healthy or should I use another brand?

Hi Jinxx, this product looks fine to me - erythritol, stevia extract and natural flavours (not sure what "natural flavours" are though). For more, have a look at this post: Complete Guide To Sweeteners on a Low-Carb Ketogenic Diet.

Tiffany 2 years ago #

Great value stevia may contain dextrose. If you have diet restrictions or allergies you may want to read ingredients list carefully. Great value Stevia is not considered organic.

You are right, they must have changed the ingredients. Last time (2 years ago) I checked, it had erythritol, stevia and natural flavours. This time they list maltodextrin!

Cheese and rum are not bulletproof. Nice recipe though.

Thanks! I make mine with rum extract and coconut milk 😊

I am thinking mini muffin tins with silicone liners would be perfect for me to use as I dont have an ice cream maker either. Great recipe, I am going to make them now.

WOW! I usually do not like anything that is a sugar substitute (even stevia) But these are outstanding! THanks So Much!!

Thanks Becky! If you don't mind sugar-free coffee, you can avoid using the sweeteners 😊

How do you make your own powdered erythritol. Waaah, I just dumped this morning's cold coffee before I sat down to check the blog.
Oh well, tomorrow.
I like this diet!

Hi K, thanks! 😊 I powder mine in food processor with a chopping blade (either Bamix or Kenwood). I prefer using my Bamix immersion blender (with the dry mill) because it's easier to clean: www.amazon.com/.../ref=as_li_qf_sp_asin_il_tlFilter (affiliate link)

Hi Tina, then use just powdered Erythritol / Swerve 😊

i made my own powdered Erythritol by using my Krups nut/bean grinder. Came out perfect! Waiting for my coffee to cool so I can finish making these fat bombs. I can hardly wIt! Thank you for the recipe!

these look delish!!! I don't have a ice-cream maker though, would just freezing the mix before churning work or maybe whipping in in a mixer??

Hi Nikki, yes you can make them without an ice-cream maker - see my comment above 😊

Angie 5 years ago #

Is there another way to make these without an ice cream maker.

Hi Angie, yes, you can pour it directly into the ice tray. You'll have to use a larger ice tray to fit ~ 2 tablespoons or make smaller fat bombs.

You can also put it into a muffin tin, muffin paper lined to freeze. Other websites do that. Works fine.

Yes, muffin cups work too. I would still use silicone than paper cups because they get wet and soggy.
