These fudgy keto brownies topped with creamy green no bake cheesecake frosting are the perfect treat for the spooky season.

Black cocoa powder makes the deepest, darkest treats perfect for Halloween! Black cocoa powder tastes slightly stronger (more bitter) than Dutch process cocoa powder so if you want these to taste milder, use half black and half Dutch process cocoa or combine it with raw cacao powder.

These keto chocolate brownie bars are topped with a ghoulish green cheesecake frosting, for which I’ve used natural food dye to colour. You could also try using matcha powder, green spirulina powder or even mashed avocado though this won't keep as long (hint: add some fresh lime juice if you go down the avocado frosting route to help with discolouration).

The cheesecake frosting is flavoured with vanilla extract although you could additionally use some peppermint extract to make a delicious chocolate & mint keto dessert.

Halloween Recipes with Black Cocoa Powder

Black cocoa powder is simply made for Halloween inspired treats! In these Black Heart Keto Cupcakes we combined black cocoa with bright red raspberry jam filling.

If you make our Low-Carb Oreo Cookies or Oreo Chaffles, add some green or red food colouring to the filling.

Finally, for a Halloween inspired breakfast meal, make this Keto Oreo Shake and add a few drops of green or red food colouring to the whipped cream topping.

Hi Martina, I would like to make this a little fluffier so it’s more like a cake rather than a brownie for my husband‘s birthday. He’s type one diabetic so low carb is a must. I will be using a different icing rather than the cheesecake topping since he’s dairy free too.  Can you give me any tips on how to turn this into more of a cake than a brownie? Thank you so much!

Hi Holly, I'm sorry for the delayed response, I hope it's not too late! I recommend this recipe instead as it's what you're looking for. Less fudgy, fluffier, closer to a cake: Chocolate Keto Blender Cupcakes (You can make a cake out of it, muffins or bake it just like brownies. You will need to adjust the baking time depending on the shape - less for muffins and more for a cake.)

These are so cute!! My kids will love them. Now I just have to locate black cocoa powder 😊 Any tips where to get it in the UK? Thanks!

Hi Cathy, I got mine on Amazon. You could even try using activated charcoal together with some Dutch process cocoa powder. This is the black cocoa powder I use: Amazon link
