How to Make It
Get ready to whip up these tasty fat bombs in just a few steps.
Set up molds
Prepare your workspace by using a silicone mini-muffin tray or silicone candy molds. If you don’t have molds, line a small loaf pan with parchment to slice into squares later.
Warm the base
In a small saucepan over low heat, add the peanut butter, coconut oil, and optional butter. Heat gently, stirring, until smooth and fully combined.
Flavor it up
Whisk in cocoa powder, powdered sweetener, vanilla extract, and a pinch of sea salt. Mix until you achieve a glossy, lump-free texture.
Taste and adjust
Dip a spoon in the mixture and taste. If you want it sweeter, add more sweetener; if it’s too thick, stir in coconut oil, one teaspoon at a time.
Add extras
Fold in the optional add-ins, such as sugar-free chocolate chips or chopped peanuts, ensuring the mixture is well combined.
Fill the molds
Pour the mixture into the prepared silicone molds, leaving a small gap at the top. For a loaf pan, pour in and smooth the top with a spatula.
Chill to set
Refrigerate for 45–60 minutes or freeze for 20–30 minutes, until firm enough to pop out of the molds. They should be solid yet soft to the bite.
Finish and store
Carefully pop them out and sprinkle with flaky sea salt if desired. Store in an airtight container in the fridge for up to 2 weeks or the freezer for up to 2 months.
