The Five Ingredients
- Natural peanut butter (1 cup): the creamy base. Choose an unsweetened one to keep the carbs low.
- Coconut oil (1/2 cup, melted): gives a smooth texture and a hint of tropical flavor. Melt it fully so the mixture stays smooth.
- Sugar-free chocolate chips (1/4 cup): add sweetness without carbs, and they soften slightly against the peanut butter.
- Powdered erythritol (1/4 cup): the sweetener. Stevia or monk fruit can replace it, so adjust the amount to the sweetness of the one you use.
- Vanilla extract (1 teaspoon): adds depth to the flavor.
Exact amounts are in the recipe card at the bottom.
How the Mixture Comes Together
Stir the peanut butter and melted coconut oil in a bowl until smooth. Add the erythritol and vanilla and stir until fully mixed, then gently fold in the chocolate chips so they are spread evenly. Line a mini muffin tin with paper liners or grease it lightly, and fill each cup about 3/4 full.
Freeze the tin for about 30 minutes, until the fat bombs are firm. Take them out of the tin and store them in an airtight container in the refrigerator or freezer. A silicone tin makes removal easier, though a metal one works too. Watch the freezing time. They should be firm but not rock-hard.
Fridge or Freezer
Fridge storage gives a softer texture, and the freezer gives a firmer bite. In the refrigerator they last up to two weeks, and in the freezer up to a month. Making a batch ahead means you have a keto snack ready whenever you want one.
Variations
- Chocolate peanut butter: add a tablespoon of unsweetened cocoa powder.
- Sea salt: a pinch gives a sweet and salty contrast.
- Nut-free: use sunflower seed butter in place of the peanut butter. Almond butter is another swap.
- Mint: a few drops of peppermint extract.
- Spicy: a pinch of cayenne pepper against the sweetness.
- Fruity: a tablespoon of crushed freeze-dried strawberries or raspberries.
- No chocolate chips: leave them out, or add nuts or seeds for texture.
Ways to Serve Them

- Alongside hot coffee or tea.
- With fresh berries, which contrast with the rich flavor.
- On a platter, sprinkled with shredded coconut.
- As a snack after a workout.
