Perfect for snowy evenings or midday slumps, they’re packed with healthy fats, zero guilt, and all the nostalgia of a Reese’s cup (but better).

In this recipe, I’ll show you how to make keto peanut butter chocolate fat bombs that are sugar-free, fuss-free, and guaranteed to keep you energized and satisfied.

🥜 Why These Fat Bombs Are a Keto Must-Have

Fat bombs are a staple in the keto community, designed to help hit daily fat macros while curbing sugar cravings. This version combines creamy peanut butter and luscious sugar-free chocolate for a treat that’s:

  • Under 2g net carbs per piece
  • Gluten-free, dairy-free (optional), and vegan-friendly
  • Ready in 20 minutes with no baking required
  • Perfect for meal prep—store them for weeks!

Unlike store-bought “low-carb” snacks, these use clean ingredients without hidden fillers. Plus, they’re endlessly customizable (think coconut flakes, sea salt, or a dash of espresso!).

  • 1 teaspoon vanilla extract

🥄 Step-by-Step Instructions

Step 1: Prep the Peanut Butter Layer

  1. In a microwave-safe bowl, combine peanut butter, 4 tablespoons melted coconut oil, vanilla extract, sweetener, and salt.
  2. Microwave in 15-second intervals, stirring until smooth. Taste and adjust sweetness.

Step 2: Layer in Molds

  1. Line a silicone mold or mini muffin tin with parchment paper.
  2. Pour the peanut butter mixture into each cavity, filling halfway.
  3. Freeze for 15 minutes to set.

Step 3: Melt the Chocolate

  1. In a double boiler, melt sugar-free chocolate chips and remaining 4 tablespoons coconut oil until silky.
  2. Stir in MCT oil (if using) for extra keto-friendly fats.

Step 4: Assemble the Fat Bombs

  1. Remove the molds from the freezer. Pour melted chocolate over the peanut butter layer.
  2. Sprinkle with crushed peanuts, shredded coconut, or sea salt.
  3. Freeze again for 45–60 minutes until firm.

Step 5: Pop Out & Store

  1. Gently remove fat bombs from molds.
  2. Store in an airtight container in the fridge for 2 weeks or freezer for 3 months.

💡 Pro Tips for Success

  1. Avoid Separation: Stir peanut butter mixture thoroughly—natural peanut butter tends to split.
  2. Sugar-Free Sweeteners: Use powdered versions to prevent graininess.
  3. Quick Fix: If chocolate hardens too fast, re-melt with a splash of coconut oil.
  4. Double the Batch: These disappear quickly—trust me!
