Tips and Variations

  • Storage - Store in a sealed container in the fridge for up to a week. Store in an airtight container, separated by wax paper, in the freezer, for up to 3 months. 
  • Reheating - Do not reheat this peanut butter fudge as it will melt. If you need it to warm up, simply leave it out to reach room temperature on its own.
  • Use other chocolate chip flavors - If you want to mix things up, you can replace the chocolate chips with other flavors such as white chocolate, caramel, etc. Of course, be sure to stick with flavors that are offered in keto-friendly forms.
  • Add nuts - If you want to add even more to your fudge, add your favorite kind of nuts! Walnuts tend to be my favorite for fudge.
  • Be sure to use the right peanut butter - You can’t just use any peanut butter for keto fudge. It has to be the all natural kind without added sugar. Check the ingredients. If it has more than peanuts, salt, and oil, it’s probably not a good choice.
  • My fudge is too hard - If your fudge is too hard, you’ve either used too much chocolate or not enough peanut butter. The fudge should be super hard, but not so hard a knife can’t easily cut through it.
  • My fudge is too soft - Odds are, you used too much peanut butter or not enough chocolate. You’ll need to adjust your amounts to make it a bit harder.

Common Questions About Keto Chocolate Peanut Butter Fudge

What Chocolate Can I Have On Keto?

There are a variety of chocolates available in the keto world. There are two things to look out for when getting chocolate for a keto diet; you want high fat and low carbs. Using darker chocolates for a keto diet bodes well. The more cacao, the less sugar, and therefore the less net carbs. There are countless brands available that are specifically keto options, if you want to take the guessing game out of it. I tend to stick with dark chocolate or Lily's as it’s my favorite keto chocolate brand.

Is Peanut Butter Ok for Ketosis?

Peanut butter is such a great part of a keto diet. It provides tons of flavor and is very healthy. Just make sure you stick to an all natural peanut butter without added sugars. You want high fat content and low carbs for keeping the body in ketosis. The all natural versions that most companies produce are simply peanuts and oil. However, the average jar of peanut butter has added sugar and a ton more ingredients that make it not so keto-friendly. So, not just any peanut butter will do, just the kind that is just peanuts and oil (sometimes salt).
