Preheat your oven to 350°F (175°C) and prepare three round cake pans by greasing them or lining them with parchment paper.

In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, granulated sugar, cocoa powder, baking powder, and salt.

In a separate bowl, combine the wet ingredients: eggs, milk, and vanilla extract, then whisk until well blended.

Divide the batter evenly into three bowls. Stir melted chocolate into one bowl, pureed strawberries into the second, and leave the third as vanilla.

Pour each batter into the prepared cake pans and bake for 25-30 minutes, or until a toothpick inserted comes out clean.

Let the layers cool in the pans for about 10 minutes before transferring to wire racks to cool completely.

Assemble the cake by placing the chocolate layer on a serving plate, frosting with cream cheese, then add vanilla and strawberry layers.

Cover the top and sides of the cake with the remaining cream cheese frosting and add any decorations like fruit sauce.
