How to make Peanut butter brookies

1. Preheat the oven to 180°C (fan 160°C) or Gas Mark 4. Lightly grease a 33 x 23 cm baking tin and line it with a piece of baking parchment, allowing it to overhang the two long sides. Secure the parchment in place with metal clips.

2. For the peanut butter cookie layer, mix the peanut butter and brown sugar together in a large bowl for a couple of minutes until well combined and slightly lightened in colour. Add the egg and egg yolks, then beat together for a further 2–3 minutes. Incorporate all the remaining ingredients, reserving 3 tablespoons of the peanuts for later, and gently mix to form a uniform cookie dough. Spread the cookie dough evenly in the prepared tin, then set aside.

3. For the brownie layer, add the butter and cocoa to a small saucepan over medium heat. Stir constantly until melted and smooth, then remove from the heat and set aside.

4. In a large bowl, combine the sugars, salt, vanilla, and eggs. Whisk together with an electric mixer for 2–3 minutes, or until slightly thickened and pale. Pour in the melted butter mixture and mix briefly until combined. Fold in the flour until just incorporated.

5. Pour the brownie batter over the cookie layer and spread it into an even layer. Sprinkle the reserved peanuts on top.

6. Bake for 25–30 minutes, or until a skewer inserted into the middle comes out with a few moist crumbs.

7. Leave the brookies to cool completely in the tin. Once cooled, use the baking parchment to lift them from the tin and cut into squares.

8. Store in a sealed container for 3–4 days.
