Keto Peanut Butter Cup Fat Bombs

10 ratings

These Keto peanut butter cups are inspired by Reese’s Peanut Butter Cups© - but with a fat bomb twist! A simple low carb chocolate fat bomb shell surrounds a center of peanut butter to create this deliciously indulgent Keto fat bomb recipe. Simple to make, these are a great way to boost your daily fat intake as well as satisfying a sweet tooth!

Can I Use A Different Nut Butter?

We have used peanut butter as the filling for our Keto fat bombs to recreate the classic flavor of Reese’s Peanut Butter Cups©. If you need to avoid peanuts, you may substitute this for an alternative Keto-friendly nut butter such as almond butter, in the same quantities. If you need to avoid tree nuts completely, you can add a few dried cranberries to the center of each fat bomb. Please be sure to adjust your macros to account for any changes made to the original recipe.

Hints and Tips

We have made this delicious Keto fat bomb recipe using chocolate truffle cases. These are the perfect size for bite-sized fat bombs. The fat bombs can also be made in small silicon molds or silicone ice cube trays. By using truffle cases, we have been able to get 12 fat bombs from the mixture.

55 min

  • Step 1

    Add the cocoa powder, coconut oil, erythritol, and vanilla extract to a food processor. Blend well to combine. You should have a smooth chocolate sauce. You may use an alternative powdered or granulated sweetener if desired, adjusting the quantities to taste. You may also use more or less erythritol as needed.
    Step 1
  • Step 2

    Select 12 truffle cases and arrange on a plate. Add a generous teaspoon of the chocolate mixture to the base of each truffle case. Transfer the plate to the fridge for 10 minutes to set and firm the chocolate base.
    Step 2
  • Step 3

    Once firm, you can fill the centers of the fat bombs. Take a half teaspoon of peanut butter and place in the center of one of the set chocolate bases. Repeat this process using up the remaining peanut butter, so the center of each base is filled.
    Step 3
  • Step 4

    Take a heaped teaspoon of chocolate mixture and spoon over the top of the peanut butter on one of the fat bombs, allowing it to coat the center and sides. Repeat this process with the remaining fat bombs using up all the chocolate mixture. Return to the fridge for a further 30 minutes to set. Store in an airtight container in the fridge until ready to serve.

    I found it just tastes like sweet coconut oil, ended up an icing consistency, tried adding more cocoa and still pretty flavorless

      Can I substitute almond butter?

        So it made double, should I eat 2 to make up for 1 serving?

          Really really happy with these. They made almost double what it said it would. But I’m not gonna complain about that.

            Coconut oil should be melted a bit. I got more of an icing consistency. Used a hand mixer, no food processor. Still tastes good

              I found it made 15 bombs using 2 heaped tsps of choc mix and 1/2 tsp of peanut butter in each., quite good taste but not the best I've had.

              Hi, the recipe calls for 12 teaspoons of peanut butter for 12 bombs but then in directions says to use only 1/2 teaspoon per bomb, so should total peanut butter be 6 teaspoons?

                Anna 3 years ago

                Using 64g of peanut butter this gave me 15 bombs with plenty of choc sauce to go around.

              If I was to use almond butter instead of peanut butter would you still use the same quantity?

                I use almond butter and monkfruit crystals instead of stevia. My yield is 24 pcs. Is there a way to change calories?

                  When this happens I copy the recipe to My Foods and then change the ingredients for my own version.

                  How much almond butter did you use instead of the peanut butter?

                I absolutely love these. I use all natural peanut butter and Pyure stevia. 😋

                    Did you use the same amount of butter?

                    Something seems off on this recipe because it taste like there is way too much coconut oil.

                      I think doing half butter and half coconut oil would be better

                    Just made these. Couldn’t wait for them to set up. When you combine two of my favourite things the wait is unbearable. They are well worth the wait.

                      The recipe says to put 1/2 teaspoon in the middle of each bomb, but it uses 12 teaspoons to make 12 bombs. Should the recipe be changed to count only 6 teaspoons of peanut. Utter for 12 bombs?

                        Good catch. I believe the macros calculations come from the ingredients. So that means more pb in my cups! Right? 😉

                        Oh good, so it’s just a typo then? I’ve noticed several calculation mistakes with member foods. I’m really hoping I can trust the app calculations!

                        Never mind, my molds made 10 small bombs when I reduced the number of servings from 12 to 2. Love the way the app changes all ingredient amounts when you change total number of servings! For 2 servings, it’s only 2 teaspoons of peanut butter, so I just divided that evenly among my 10 little bombs.
