I know, I know – “white chocolate isn’t chocolate,” and no one likes it but me. But, it’s my recipe blog and so I’m going to post a delicious white chocolate peanut butter fat bomb recipe because I want to. To me, these taste like the inside of my favorite childhood treat – Reese’s peanut butter cups. And while Reese’s now has a dairy-free version (yay!) they don’t have a sugar-free one, so here we are.

Typically white chocolate recipes call for powdered milk of some sort, but instead of powdered milk, I used a vanilla protein powder.  I’ll be honest, the result isn’t perfect. Commercial white chocolate uses emulsifiers and carb-heavy ingredients and sweeteners to get that smooth texture. So without those, the result here is a white chocolate that’s  a tad bit gritty. That said, I consider it a small sacrifice for a keto treat that isn’t loaded with strange ingredients that hurt my stomach. 

If you’re new to ketogenic diets, you may be wondering what the point of a fat bomb is. I didn’t really get the whole concept at the beginning either, but it’s basically a way to include more healthy fats in your diet, or to make sure that you eat enough calories, in a tasty way that doesn’t feel like a fat overload. I don’t tend to like eating straight fat (I genuinely do not understand how some people can just bite into a stick of butter, but to each his own), and so fat bombs that contain protein and some carbs/fiber work better for me.

Notes on Making Low Carb White Chocolate Peanut Butter Cup Fat Bombs:

  • Because the protein powder I use contains stevia, I don’t add any additional sweeteners to this recipe. If your protein powder isn’t as sweet as you would like, pretty much any sweetener can be used here. 
  • Keep in mind that granulated sweeteners will retain their grittiness, so a powdered or liquid sweetener will yield a smoother texture. 
  • If you don’t want to use a protein powder in this recipe, you can replace it with coconut milk powder, which also makes a great creamer for coffee or tea. If you go this route, just add a teaspoon of vanilla extract for that vanilla flavor in white chocolate.
  • If you don’t want to use cocoa butter, just double the coconut oil. The flavor and texture will be different, but it will still taste good!
  •  Keep in mind while calculating macros that certain sugar alcohols, like erythritol, should be subtracted from the total carbs! For this recipe, that is 3.3g total carbs – 1.1g fiber = 2.2g net carbs
  •  While I strive to provide accurate nutrition information, there are variations across brands and types of ingredients. So, if you’re using other brands than those mentioned, your macros may be different. All nutrition info is calculated from the USDA values for each ingredient, unless a brand is specifically mentioned (or no generic listing is available), and are for information purposes only! 
  • If you know of a commercial low carb and dairy-free white chocolate peanut butter snack, I would absolutely love to know about it!
