For the pumpkin brownies, sauté the pumpkin cubes in a little butter, add 100 ml water and simmer until the pumpkin is soft. Drain and finely puree the pumpkin.
Cut chocolate and butter into small pieces, melt together in a saucepan over very low heat.
Beat eggs and sugar until foamy, then slowly stir in chocolate-butter mixture and pumpkin puree. Finally, fold in hazelnuts, flour and baking powder.
Line a baking tray with baking paper. Empty the mixture onto it and smooth it out with a pastry card. Bake in the preheated oven at 170 °C for 20-25 minutes.
Let the pumpkin brownies cool slightly and cut into small cubes, sprinkle with powdered sugar and serve immediately.
Preparation Tip:
The pumpkin brownies go perfectly with a scoop of vanilla ice cream.
