How to Make Keto Peanut Butter Chocolate Fat Bombs
Ingredients
- Natural peanut butter (unsweetened, no added oils)
- Coconut oil (refined for neutral flavor or unrefined for coconut flavor)
- Unsalted butter or ghee (optional for richness)
- Unsweetened cocoa powder or cacao powder
- Powdered keto sweetener (erythritol, allulose, or a blend; powdered dissolves best)
- Vanilla extract
- Pinch of sea salt
- Optional add-ins: sugar-free chocolate chips, chopped peanuts, unsweetened coconut flakes
- Optional coating: flaky sea salt or a dusting of cocoa powder
Directions
- Set up your molds. Use 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 1/2 cup peanut butter, 1/3 cup coconut oil, and 2 tablespoons unsalted butter (optional but adds creaminess). Heat gently, stirring until smooth and fully combined.
- Flavor it up. Whisk in 3 tablespoons unsweetened cocoa powder, 2–4 tablespoons powdered keto sweetener (to taste), 1 teaspoon vanilla extract, and a pinch of sea salt. Mix until glossy and lump-free.
- Taste and adjust. Dip a spoon in and taste. If you want it sweeter, add a bit more powdered sweetener. If it’s too thick, stir in 1–2 teaspoons of coconut oil.
- Add extras (optional). Fold in 2 tablespoons of sugar-free chocolate chips or a tablespoon of chopped peanuts for texture. Stir evenly.
- Fill the molds. Pour the mixture into the silicone molds, leaving a small gap at the top. If using 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 molds. They should be solid but soft to the bite.
- Finish and store. Pop them out and sprinkle with a little flaky sea salt if you like. Store in an airtight container in the fridge for up to 2 weeks or the freezer for up to 2 months.
