Ingredients: What You’ll Need

For about 16 Fat Bombs (depends on mold size)

  • ½ cup (120 g) natural peanut butter
    • Unsweetened, no added sugar; creamy or crunchy
  • ⅓ cup (75 g) unsalted butter
    • Or ⅓ cup (75 g) of coconut oil for dairy-free
  • 3 Tbsp (15 g) unsweetened cocoa powder
  • ¼–⅓ cup (40–55 g) powdered keto sweetener, to taste
    • Allulose, erythritol/monk fruit, etc.
  • 1 tsp vanilla extract
  • Pinch of fine sea salt

Optional Add-Ins

  • 2–3 Tbsp chopped peanuts (for crunch)
  • 2–3 Tbsp sugar-free chocolate chips

Equipment

  • Silicone candy molds, a mini muffin tin with liners, or a small baking dish lined with parchment

Instructions: Step-by-Step Preparation

  1. Melt the Peanut Butter & Butter
    • In a small saucepan over low heat, combine:
      • Peanut butter
      • Butter (or coconut oil)
    • Stir until melted and smooth.
    • Alternatively, microwave in a heat-safe bowl in 20–30 second bursts, stirring between each, until smooth.
  2. Add Cocoa & Sweetener
    • Remove from heat.
    • Whisk in cocoa powder, powdered sweetener, vanilla, and salt until completely smooth and glossy.
    • Taste (carefully, it may be warm) and adjust the sweetness to your liking.
  3. Fold In Extras (Optional)
    • If using chopped peanuts or sugar-free chocolate chips, let the mixture cool for a minute so the chips don’t fully melt.
    • Stir in your add-ins.
  4. Fill Molds or Pan
    • Pour or spoon the mixture into silicone molds or mini muffin liners, filling each about ¾ full.
    • If using a lined baking dish, pour in and spread into an even layer (you’ll cut into squares later).
  5. Chill Until Firm
    • Refrigerate for 30–60 minutes, or freeze for about 20 minutes, until set and solid.
  6. Unmold & Serve
    • Pop fat bombs out of molds or cut into small squares if using a pan.
    • Store chilled and enjoy as needed.

How to Store It

  • Refrigerator:
    • Store in an airtight container for up to 1–2 weeks.
  • Freezer:
    • Freeze up to 2 months in a sealed container or bag.
    • Let sit a few minutes at room temp before eating if frozen—they’ll be quite firm.

Smart Ingredient Swaps

  • Nut-Free:
    • Use sunflower seed butter or almond butter instead of peanut butter (watch labels for added sugar).
  • Dairy-Free:
    • Use coconut oil instead of butter.
    • Check that your chocolate chips (if using) are dairy-free and sugar-free.
  • Sweeter / Less Sweet:
    • Adjust the sweetener up or down; start with less and add to taste.
  • Flavor Variations:
    • Add ¼–½ tsp cinnamon for a warm twist.
    • Add a drop or two of peppermint extract for chocolate-mint fat bombs.

  • As a quick snack between meals

Notes

  • Use natural peanut butter with no added sugar for the best keto macros.

    Macros vary by nut butter, sweetener, and portion size.
    Keep chilled—fat bombs soften at room temperature, especially if made with coconut oil.
