Ingredients
  

  • Unsweetened nut butter (1/2 cup) – Almond or peanut butter works; choose a no-sugar-added option.
  • Butter or coconut oil (1/4 cup) – Butter gives a richer flavor; coconut oil keeps it dairy-free.
  • Unsweetened baking chocolate (3 oz) – Or use sugar-free dark chocolate chips.
  • Vanilla whey or egg white protein powder (1/2 cup) – Look for a low-carb, clean-ingredient brand.
  • Unsweetened cocoa powder (2 tablespoons) – Deepens the chocolate flavor.
  • Powdered keto sweetener (1/4–1/3 cup) – Allulose, erythritol, or a blend; adjust to taste.
  • Heavy cream or full-fat coconut milk (3–4 tablespoons) – For creaminess and easier mixing.
  • Vanilla extract (1 teaspoon) – Rounds out the chocolate notes.
  • Pinch of fine sea salt – Balances sweetness.
  • Optional add-ins: Chopped pecans or walnuts (1/4 cup), unsweetened shredded coconut (2 tablespoons), espresso powder (1/2 teaspoon), or a few drops of peppermint extract.

Method
 

  1. Prep the pan. Line a small loaf pan or square dish (about 8x4 inches) with parchment, leaving overhang to lift the fudge out later.
  2. Melt the base. In a heatproof bowl, combine nut butter, butter or coconut oil, and chopped unsweetened chocolate. Microwave in 20–30 second bursts, stirring between each, until smooth. You can also melt over a double boiler.
  3. Whisk in flavors. Stir in vanilla extract and a pinch of salt. Let the mixture cool for 1–2 minutes so it’s warm, not hot.
  4. Add dry ingredients. Sift in protein powder and cocoa powder to avoid lumps. Stir gently until mostly incorporated.
  5. Sweeten and loosen. Add powdered keto sweetener and 2 tablespoons of cream. Stir until glossy. If the mixture is too thick or crumbly, add more cream 1 tablespoon at a time. You’re aiming for a thick, spreadable batter.
  6. Taste and adjust. Sweetness and bitterness vary by chocolate and sweetener. Add a little more sweetener or cocoa as needed. If using espresso powder or peppermint, mix it in now.
  7. Fold in extras. If adding nuts or coconut, fold them in gently to distribute evenly.
  8. Spread and smooth. Transfer the fudge mixture to the lined pan. Smooth the top with a spatula. Tap the pan on the counter to release air bubbles.
  9. Chill to set. Refrigerate for 45–60 minutes, or freeze for 20–25 minutes, until firm enough to slice.
  10. Cut into bites. Lift out using the parchment and cut into 16–20 small squares. Keep chilled until serving.
