In a large mixing bowl, whisk together eggs, granulated sugar, and vanilla sugar until light and fluffy.

Sift in the cocoa powder, flour, and salt, folding gently until just combined.

Gradually mix in the milk and melted butter, stirring until you achieve a smooth batter.

Preheat your oven to 350°F (175°C). Grease and flour a round cake pan.

Pour the batter into the prepared pan, smoothing the top with a spatula.

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

In a medium bowl, blend the cream cheese and cooked condensed milk until smooth.

Gently fold in the crushed Oreo cookies.

Once the cake has cooled, slice it horizontally into two equal layers.

Spread the Oreo cream filling evenly over the bottom layer, then carefully place the second layer on top.

In a small saucepan over low heat, melt a few tablespoons of peanut butter, stirring until it reaches a pourable consistency.

Drizzle the peanut butter glaze over the top of the cake, allowing some to drip down the sides.

Let the cake set for a few minutes to allow the glaze to firm up slightly.

Slice and serve this luxurious cake as the perfect dessert for any chocolate lover’s celebration or as a decadent treat to enjoy any day of the week.
