How to Make It

1. Prep the pans: Heat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment. Lightly flour the sides.
2. Make the base batter: In a large bowl, whisk flour, baking powder, baking soda, and salt.In a mixer, beat butter and sugar until light and fluffy, about 3 minutes. Add eggs one at a time. Mix in sour cream and vanilla.

   Alternate adding dry ingredients with buttermilk, beginning and ending with dry. Mix just until smooth.

3. Divide the batter evenly: Weigh or eyeball into three bowls. Aim for equal portions so layers bake evenly.
4. Flavor the chocolate batter: Stir cocoa with hot water or coffee to make a paste.Fold into one portion until fully combined.
5. Flavor the strawberry batter: Fold strawberry puree and jam into another portion. Add a tiny bit of pink coloring if you like.
6. Leave the vanilla batter plain: This is your classic vanilla layer—no add-ins needed.
7. Bake the layers: Spread each batter into its pan. Bake 18–22 minutes, or until a toothpick comes out clean and edges pull slightly from the pan.Cool 10 minutes, then turn out onto racks to cool completely.
8. Make the frosting: Beat butter until creamy. Add powdered sugar in batches, alternating with heavy cream. Mix in vanilla and salt.Beat 2–3 minutes until fluffy. Adjust cream or sugar for spreadable consistency.
9. Level and stack: If needed, level cooled cakes with a serrated knife. Place the chocolate layer on a board, add a generous layer of frosting.Top with strawberry, frost again, then finish with the vanilla layer.
10. Crumb coat and chill: Spread a thin layer of frosting over the whole cake to lock in crumbs. Chill 20–30 minutes.
11. Final frost and decorate: Apply a smooth final coat. Add chocolate shavings on one side and fresh strawberries on top for a classic Neapolitan touch.

FAQ

Can I use boxed cake mixes for each layer?

Yes. Use one box per flavor, bake in three pans, and proceed with the frosting and assembly. It’s a quick shortcut that still looks impressive.

How do I get strong strawberry flavor?

Use a thick puree made from ripe berries, or stir in 2–3 tablespoons of freeze-dried strawberry powder. Avoid adding too much liquid.

What if I only have two pans?

Bake two layers first, cool briefly, then wash, line, and bake the third. The batter can rest at room temperature for about 30 minutes.

Can I make cupcakes instead?

Absolutely. Layer small scoops of each batter into liners and bake 16–20 minutes. Frost as desired.

How do I keep the layers from sliding?

Chill the layers before stacking, use a thicker frosting for the fillings, and insert a skewer or two down the center if transporting.
