Did you grow up eating Frosty? I did and this keto chocolate frosty tastes just like the real thing! This frozen chocolate smoothie is super easy to make and can be ready, freezing and all in less than an hour.

This is also a great low-carb recipe to make with the kiddos, especially in the summer months, as it’s easy enough with no special tools required. I love my ice cream maker but let’s face it, it can be a pain and I hardly ever have it in the freezer when the ice cream craving hits.

Looks super so wanted to try this, get a bit confused on the measurements though.
3 tbsp cacao equals 16 g
4 tbsp powdered swerve equals 40 g
Measuring in grams 😀
Does not seem correct? Or am I missing something?

Hi Linda, yes that is about right although small differences are likely. It has to do with density and per tablespoon, teaspoon or cup, erythritol weighs more than cacao powder.

Does this freeze solid or is it scoopable when frozen?

Hi Jacinda, this will freeze solid but you could spoon it in single-serve containers and then let it soften at room temperature for 10-15 minutes before serving.

This sounds wonderful I cant wait to try it! I need to know if I should use granular Swerve of confectioners?

Hi Jacquelin, confectioners Swerve or powdered erythritol, or even stevia drops will work well. Granulated would make it gritty.

Wow. This was incredible. I didn’t whip it enough to get it thick but the taste was exactly a Wendy’s frosty

Thank you Wendy, I'm glad you enjoyed!

This is delicious! I used to like my frosty more on that thick liquid side, so I stop whipping a little bit before what the picture looks like and then freeze. It gives that more liquid, but still need a spoon texture.
Great copy-cat recipe.

Thank you Crystal, I'm glad you enjoyed!

Could full-fat coconut milk work instead of heavy cream to make this frosty dairy-free? Any other suggestion? Thank you!

Yes you can! You will be able to taste the coconut although the cacao powder should mask the taste a bit. I like Aroy-D (sold in cartons) because it tastes really fresh!

Can you add extra Swerve instead of the Stevia? I can't tolerate Stevia or Sucralose or aspartame without swelling up like a balloon but Swerve doesn't bother me.

Absolutely! The only issue with Swerve is that it may make the mousse a little gritty (especially once frozen) but I personally don't mind it as I don't think it's too obvious. I use it to make low-carb ice cream all the time 😊
