Jump to recipe

Chocolate, peanut butter, and caramel in one pan. The filling sits between two layers of brownie batter, with a quick swirl to bring it together.

This recipe first appeared here in September 2014. The quantities below come from that original recipe, including the 20 cm square pan and lower baking temperature.

A couple of useful details

The original recipe doesn't give a measured quantity of peanut butter or dulce de leche. Add them in teaspoonfuls across the first layer of batter, leaving space between the dollops, then cover with the second layer.

Use unsalted butter and peanut butter without added sugar, as listed. If your butter comes in US sticks, 250 g is a little more than two full sticks; the butter conversion calculator gives the equivalent for your pack.

Method

  1. Prepare the pan. Preheat the oven to 160°C (320°F). Line a 20 × 20 cm (about 8-inch square) baking pan with baking paper.
  2. Melt the chocolate. Put the butter and chocolate in a heatproof bowl over a saucepan of simmering water. Stir occasionally until melted and smooth. Set aside to cool slightly.
  3. Make the batter. Mix the eggs and brown sugar in a large bowl. Sift in the flour, cocoa, and baking powder. Add the melted chocolate mixture and vanilla, then mix just until combined.
  4. Add the filling. Spread half the batter in the pan. Dot teaspoonfuls of peanut butter and dulce de leche over it. Cover with the remaining batter, then swirl gently with a butter knife.
  5. Bake. Bake for 55–60 minutes, until the center is just set. Avoid baking until the brownies are dry.
  6. Cool and cut. Leave in the pan for 10 minutes, then lift onto a wire rack. Allow to cool before cutting into 16 squares. Serve with ice cream if you like.

Out of baking powder? The substitute calculator works out the small amount needed here, including an easier way to measure the blend.

No chocolate bar on hand? The chocolate banana brownies use cocoa powder and ripe bananas instead.
