Ingredients: What You’ll Need

Peanut Butter Base

  • 1 cup (240 g) natural peanut butter
    • Unsweetened, no added sugar; creamy works best
  • ½ cup (115 g) unsalted butter, melted
    • Or ½ cup (115 g) of coconut oil for dairy-free
  • ½ cup (50 g) fine blanched almond flour
  • ½ cup (80–90 g) powdered keto sweetener
    • Allulose or erythritol/monk fruit blend, to taste
  • 1 tsp vanilla extract
  • Pinch of fine sea salt (skip if peanut butter is very salty)

Chocolate Topping

  • 1 cup (170 g) sugar-free chocolate chips
    • Or chopped sugar-free dark chocolate
  • 3 Tbsp (45 g) peanut butter
  • 1–2 Tbsp butter or coconut oil (optional, for softer topping)

Instructions: Step-by-Step Preparation

  1. Prep the Pan
    • Line a 20 x 20 cm (8 x 8 inch) square pan with parchment paper, leaving overhang for easy lifting.
  2. Make the Peanut Butter Base
    • In a mixing bowl, combine:
      • Peanut butter
      • Melted butter
      • Almond flour
      • Powdered keto sweetener
      • Vanilla
      • Salt
    • Stir until smooth, thick, and well combined.
    • Taste and adjust the sweetness if needed.
    • Spread mixture evenly into the lined pan, pressing it firmly into a smooth, even layer.
    • Chill in the fridge while you make the chocolate topping.
  3. Make the Chocolate Topping
    • In a heatproof bowl, combine:
      • Sugar-free chocolate chips
      • Peanut butter
      • Butter/coconut oil (if using)
    • Microwave in 20–30 second bursts, stirring between each, until melted and smooth.
    • Or melt gently over a double boiler on the stove.
  4. Assemble the Bars
    • Pour the melted chocolate mixture over the chilled peanut butter base.
    • Tilt the pan or use a spatula to spread the topping evenly.
    • Tap the pan lightly on the counter to smooth out any bubbles.
  5. Chill Until Firm
    • Refrigerate for 1–2 hours, or freeze for about 30–40 minutes, until completely set.
  6. Slice & Serve
    • Once firm, lift the slab out of the pan using parchment.
    • Use a sharp knife to cut into 16–20 bars (or smaller squares for bite-sized pieces).

How to Store It

  • Refrigerator:
    • Store bars in an airtight container with parchment between layers for up to 1–2 weeks.
  • Freezer:
    • Freeze up to 2 months.
    • Thaw in the fridge or eat slightly chilled; they’re delicious straight from the freezer if you like a firmer bar.

Smart Ingredient Swaps

  • Nut-Free:
    • Use sunflower seed butter instead of peanut butter (check labels for added sugar).
  • Different Nut Butters:
    • Almond or cashew butter works great; macros will vary slightly.
  • Sweeter / Less Sweet:
    • Adjust the powdered sweetener up or down to taste in the base.
    • If your chocolate is very dark, you can add 1–2 Tbsp powdered sweetener to the chocolate topping as well.
  • Firmer vs. Softer Bars:
    • More butter/coconut oil in the topping = softer top.
    • Less added fat = firmer top that’s more “snappy.”

How to Serve It (Keto-Friendly)

Serve No-Bake Keto Peanut Butter Chocolate Bars:

  • As a dessert square after dinner
  • With coffee or tea as an afternoon treat
  • On a platter with other low-carb sweets for parties

They’re rich, so small pieces go a long way—especially nice:

  • Topped with a sprinkle of flaky salt
  • Served with a dollop of whipped cream (unsweetened or lightly sweetened with keto sweetener)
