Black and White Brownie Sandwiches (บราวนี่แซนด์วิชแบล็กแอนด์ไวท์)

1.Line an 8×8-inch baking pan with parchment paper. Preheat the oven to 180°C (top and bottom heat).

2.Place dark chocolate and black cocoa powder in a heatproof bowl.

3.Melt the butter over medium heat until it turns golden brown (brown butter). Strain into the chocolate bowl and stir until smooth. Let cool slightly.

4.In another bowl, whisk together the eggs, granulated sugar, brown sugar, and vanilla extract for about 3 minutes until slightly thickened.

5.Pour in the chocolate mixture and whisk until combined. Add the flour and fold gently until smooth and well incorporated.

6.Pour the batter into the prepared pan and smooth the surface. Bake for about 18 minutes, until the edges are set but the center remains slightly fudgy.
Cool completely, then refrigerate until firm before cutting in half.

7.Beat butter and icing sugar until light and fluffy. Add melted white chocolate and mix well. Add whipping cream, vanilla, and salt, and continue beating until smooth and creamy.

8.Place one brownie half on a flat surface, spread the cream evenly, and top with the remaining brownie. Press gently to adhere.

9.Refrigerate for at least 1 hour until the filling is set. Slice into pieces with a warm knife before serving.
