A decadent, fudgy bake crafted with rich Belgian chocolate and premium inclusions, delivering a dense, melt-in-the-mouth texture.
Grease and line a 20cm square baking tin with baking paper and preheat the oven to 180C.
Add the chocolate and butter to a heatproof bowl and microwave in 30 second bursts until melted. Set aside to cool.
Add the eggs and sugars to a large mixing bowl and beat with an electric hand whisk until pale and fluffy – about 5 minutes.
Pour the cooled chocolate mixture into the bowl with the eggs and gently fold together with a wooden spoon until just combined.
Sift in the flour and cocoa powder and fold again until combined.
Fold through 6 of the broken Kinder Bueno bars (reserving 3 to decorate the top later).
Transfer the mixture to your prepared baking tin, smoothing everything up to the edges in an even layer with a spatula.
Bake for 25-30 minutes, until crackly on top and a skewer poked into the center comes out with just a few moist crumbs.
Whilst the brownie is still hot, gently push the remaining pieces of Kinder Bueno bar onto the top.
Leave in the tin for about 15 minutes before transferring to a wire rack to cool completely (about 2 hours).
Slice into squares and enjoy!
