cocoa powder - use the unsweetened cocoa
sugar-free maple syrup - for best results, use a keto-friendly monk fruit syrup such as Lakanto Sugar-Free Maple Syrup
finely chopped walnuts - walnuts are a great source of protein; be sure to use unsalted walnuts
vanilla extract - pure vanilla extra tastes the best

How to Make Them

(1) Line a loaf pan with parchment paper and set aside. Add walnuts to a ziplock bag. Use a rolling pin to crush the nuts into small bits.
(2) Melt coconut oil in a glass measuring cup. Add cocoa powder, sugar-free maple syrup, vanilla extract, and a dash of salt. Whisk to combine. Taste and adjust salt and sweetener if needed. Stir walnuts into cocoa mixture.
(3) Transfer the mixture to the prepared loaf pan and spread into an even layer. A spatula works well for this step. Place the pan in the freezer to allow the chocolate to harden, about 30 minutes.

What sweetener? I kept adding vanilla and maple extract, since the chocolate was so bitter. I finally added a little bit of actual sweetener at a time and got most of the bitter taste down somewhat. I loved the quickness of the recipe; but taste is awful. How do I corrrect thaat?
Anne Clark
Hey Rosemary! So the sweetener for this recipe is the maple syrup. But if that's no sweet enough for you, you can always try adding a little monk fruit sweetener. I hope this helps!

I just made this delicious treat with an aforehand experience with
cocoa /bakers powders. Because of my sensitivity to bitterness with the powders, I successfully reduce powders by half and offset with sugar free Coco nibs. I use this practice for anything chocolate. I hope this helps!!!
