Instructions

  1. 1

    Line an 8" / 20cm square pan with baking paper and grease lightly.

  3. 3

    Melt butter and chocolate in a heatproof bowl using 30-second microwave bursts, stirring until smooth.

  4. 4

    Stir in brown sugar, then eggs and vanilla. Mix until smooth. Fold in flour, cocoa, and salt.

  5. 5

    Pour half the batter into pan. Place frozen peanut butter slab on top. Cover with remaining batter.

  6. 6

    Dollop reserved peanut butter over surface and swirl with knife or teaspoon to create patterns.

  7. 7

    Bake at 180°C/350°F (160°C fan) for 32 minutes. Edges should be firm, middle slightly jiggles.

Recipe Notes

  • Use commercial smooth peanut butter for proper consistency; natural peanut butter is too runny.

  • Dark chocolate should be 45% cocoa or less for best fudgy texture.

  • Swirls do not need to be precise; the frozen peanut butter slab ensures thick swirls.

  • Cup measures differ slightly globally; follow weights for precision.

  • Store airtight at room temperature for up to 4 days or freeze for up to 3 months. Serve at room temperature for fudgy texture.
