Chocolate-hazelnut brownie with amaretto

Ingredients:

• 110 g butter, plus more for greasing
• 250 g of bittersweet chocolate
• 1 and 1/4 cups premium flour
• 1 teaspoon baking powder
• 4 large eggs
• 2 tbsp. sugar
• 2 tbsp. l. amaretto liqueur
• 1.5 cups walnuts
• Powdered sugar for decoration

Preparation:

1. Preheat oven to 180°C.
   
   Line a square baking pan with parchment paper, allowing the edges to extend slightly beyond the pan. Grease the paper with butter to prevent the cake from sticking. Melt the butter and chocolate in a double boiler and gently stir until smooth. Remove from heat and let cool.
2. Combine flour, baking powder, and salt in a bowl. Whisk the eggs, sugar, and amaretto until smooth. Pour in the chocolate mixture and continue mixing thoroughly. Add the flour mixture and walnuts and stir with a wooden spoon.
   
   Transfer the batter to a baking pan and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. When done, invert the pie onto a cutting board, remove the parchment paper, and cut into squares. Dust with powdered sugar and serve.
