Indulge in these incredibly rich and fudgy brownies, featuring a hidden layer of gooey caramel or chocolate hazelnut spread. Perfectly set on top with a soft, melt-in-your-mouth center, they are the ultimate treat for any chocolate lover.
Preheat your oven to 180°C (160°C fan/gas mark 4). Grease and line a 20cm square baking tin with parchment paper.
In a small saucepan over low heat, gently melt the butter, light brown sugar, chocolate pieces, and golden syrup. Stir until the mixture is smooth and glossy, then remove from the heat and set aside to cool slightly.
In a large mixing bowl, whisk the eggs and golden caster sugar together for several minutes until the mixture is pale, light, and fluffy. This step is crucial for the brownie's texture.
Stir the vanilla extract into the egg mixture. Sift in the plain flour, baking powder, and cocoa powder. Pour in the melted chocolate mixture and fold everything together quickly until just combined.
Pour half of the brownie batter into the prepared tin. Drop spoonfuls of dulce de leche or chocolate hazelnut spread across the surface. Cover with the remaining batter and add a few more dollops of spread on top if desired.
Bake for 30 minutes. The top should be set and slightly cracked, but the center should still have a slight wobble when the tin is gently shaken.
Allow the brownies to cool completely in the tin before slicing into squares. For a finishing touch, dust with cocoa powder or icing sugar.
For the best texture, do not overbake; the 'wobble' is key to a gooey center. If you prefer a cleaner cut, chill the brownies in the fridge for an hour before slicing. These brownies stay fresh in an airtight container for up to 3 days.
