Steps

1

Melt the butter in a saucepan over low heat.
2

Once the butter is melted, remove the saucepan from the heat and add finely crushed chocolate. Mix well until smooth.
3

In a large bowl, beat the eggs. Gradually add the brown sugar in two parts, beating until the mixture triples in volume.
4

Add the melted chocolate from step 2 to the beaten eggs and mix quickly.
5

Add the whole wheat flour, baking powder, cocoa powder, crushed walnuts, and salt. Mix quickly and roughly.
6

Line a 8x8 inch square baking pan with parchment paper (with the sides up) and pour in the batter.
7

Arrange the roughly crushed Oreo cookies on top of the batter.
8

Bake in a preheated oven at 350°F (180°C) for about 30 minutes.
9

Let cool, then cover with plastic wrap to prevent drying. Refrigerate for 1-2 days before cutting into 2-inch squares.
