How to Make Keto Fat Bombs (Step-by-Step Instructions)

Step 1: Melt the fats
In a small saucepan or microwave-safe bowl, combine the peanut butter, butter, and coconut oil. Warm gently over low heat or in 30-second intervals in the microwave until fully melted and smooth. Stir occasionally to prevent burning.

Step 2: Add the flavor
Remove from heat and whisk in cocoa powder, sweetener, vanilla extract, and a pinch of salt. Stir until everything is completely blended and no lumps remain.

Step 3: Pour and set
Spoon the mixture into silicone molds. Fill each cavity evenly. If you want added crunch or variety, sprinkle chopped nuts or chocolate chips on top.

Step 4: Freeze
Place the mold in the freezer for at least 1 hour or until completely set. Once firm, pop out the fat bombs and store them in an airtight container.

Step 5: Enjoy!
Keep these stored in the freezer or fridge and grab one anytime you need a little keto bite low carb snack to power through the day.
