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

In a large mixing bowl, sift together the flour, cocoa powder, sugar, baking powder, and salt. Whisk until well combined.

In a separate bowl, whisk together the eggs, milk, and vanilla extract until fully blended. Gradually add this mixture to the dry ingredients.

Divide the batter into three bowls. In the first, fold in the melted chocolate; in the second, add pureed strawberries. Leave the third plain.

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

Once baked, cool the cakes in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

Beat together cream cheese and confectioners' sugar until smooth, adding a splash of vanilla extract for flavor.

Assemble the cake by placing the chocolate layer down, spreading frosting, followed by the vanilla layer, more frosting, and topping with the strawberry layer.

Decorate with fresh strawberries or chocolate shavings and serve your delightful Neapolitan Cake.
