3 Ingredient peanut butter cookies can be the perfect keto snack! That's because if you make them right, each cookie will have only 2.5 grams of net carbs.
The original three ingredient peanut butter cookie recipe uses egg, peanut butter and sugar. However, today's cookies are a low carb and keto-friendly version, so we'll be swapping out the sugar for erythritol.

If you don't know what erythritol is, it's a calorie free - and thus carb free - sweetener. The brand of erythritol I like to use is Swerve - or Sukrin -because it dissolves better than the other brands out there.
For today's peanut butter cookie recipe I'll be using granulated Swerve, but they also have a confectioners erythritol that is amazing for fat bombs. I actually used the confectioners erythritol in my Chocolate Fat Bomb Recipe, and it was a game changer!
These 3 ingredient peanut butter cookies aren't just great for keto though, they taste great too! These cookies turn out unbelievably soft and chewy, they're perfectly sweetened, and they're jam packed with peanut butter flavor.
