This Delightful Neapolitan Cake Recipe brings the classic chocolate, vanilla, and strawberry combination into one colorful layer cake. The chocolate layer is cocoa-rich, the vanilla layer is soft and buttery, and the strawberry layer gets its flavor and pink color from freeze-dried strawberries rather than extra liquid that could affect the cake’s structure.

The three 8-inch layers are baked separately from one divided vanilla cake batter, then stacked with smooth vanilla buttercream. Allow enough time for the layers to cool completely before assembly; frosting warm cake can soften the buttercream and make the layers slide.

Ingredient Notes

Delightful Neapolitan Cake Recipe ingredients

For the Cake Layers

■ 2¾ cups (330 g) all-purpose flour, spooned and leveled
■ 2½ teaspoons baking powder
■ ½ teaspoon fine salt
■ ¾ cup (170 g) unsalted butter, softened to room temperature
■ 1¾ cups (350 g) granulated sugar
■ 4 large eggs (about 200 g without shells), room temperature
■ 1 tablespoon (15 ml) vanilla extract
■ 1 cup (240 ml) whole milk, room temperature
■ ½ cup (120 g) full-fat sour cream, room temperature
■ ¼ cup (22 g) unsweetened natural cocoa powder, sifted
■ ½ cup (15 g) freeze-dried strawberries, ground into a fine powder
■ 2 tablespoons (30 ml) whole milk, divided, for adjusting the chocolate and strawberry batters

For the Vanilla Buttercream

■ 1½ cups (340 g) unsalted butter, softened to room temperature
■ 5 cups (600 g) powdered sugar, sifted
■ 2 teaspoons vanilla extract
■ ¼ teaspoon fine salt
■ ¼ cup (60 ml) heavy cream, plus up to 2 tablespoons (30 ml) more as needed
■ Optional Garnish
■ ¼ cup (8 g) freeze-dried strawberries, roughly crushed, optional
■ 1 ounce (28 g) semisweet chocolate, finely grated or shaved, optional

Freeze-dried strawberries: These provide concentrated strawberry flavor without introducing the moisture found in fresh berries or puree. Freeze-dried raspberries can be substituted, but they will produce a more tart berry flavor. Fresh strawberries are not a direct substitute because they significantly change the batter's moisture level.
Natural cocoa powder: Natural unsweetened cocoa gives the chocolate layer a recognizable cocoa flavor without adding melted chocolate. Dutch-process cocoa can alter flavor and acidity and is not the preferred direct substitute in this batter.
Sour cream: Sour cream adds moisture and richness while helping create a tender crumb. Full-fat plain Greek yogurt can replace it in the same quantity, though the cake may taste slightly tangier and feel a little firmer.
Whole milk: Whole milk contributes both moisture and fat. Reduced-fat milk can be used, but the cake may be slightly less rich. Avoid replacing it with water.
Unsalted butter: Butter provides flavor and structure in both the cake and frosting. Salted butter can work if necessary, but omit or reduce the added salt to prevent an overly salty finish.

Step-by-Step Method

Prepare the pans and oven. Preheat the oven to 350°F (175°C). Grease three 8-inch (20 cm) round cake pans and line the bottoms with parchment paper. Lightly grease the parchment as well.
Combine the dry ingredients. Whisk the all-purpose flour, baking powder, and salt together in a medium bowl. Set aside.
Cream the butter and sugar. In a large bowl, beat the softened butter and granulated sugar on medium-high speed for about 3 to 4 minutes. The mixture should become noticeably lighter in color and fluffy rather than dense or greasy.
Add the eggs and vanilla. Beat in the eggs one at a time, mixing until each is incorporated before adding the next. Scrape down the bowl as needed. Mix in the vanilla extract. If the mixture looks slightly curdled after adding the eggs, continue with the recipe; it should smooth out once the dry ingredients are incorporated.
Finish the base batter. Whisk the whole milk and sour cream together. With the mixer on low, add the flour mixture in three additions, alternating with the milk mixture in two additions. Begin and end with the flour. Mix only until the last streaks of flour disappear. The batter should be thick, smooth, and spoonable.
Divide the batter. Divide the batter as evenly as possible among three medium bowls. A kitchen scale is helpful for creating layers of similar thickness.
Flavor the three layers. Leave one portion as vanilla. Fold the sifted cocoa powder and 1 tablespoon (15 ml) of the additional whole milk into the second portion until evenly chocolate-colored. Fold the ground freeze-dried strawberries and the remaining 1 tablespoon (15 ml) additional whole milk into the third portion until evenly pink with no pockets of strawberry powder.
Bake the cakes. Spread each batter into a prepared 8-inch pan and smooth the tops. Bake for about 22 to 27 minutes, rotating the pans if your oven browns unevenly. The cakes are done when the tops spring back lightly, the edges begin to pull away from the pans, and a toothpick inserted near the center comes out clean or with a few moist crumbs.
Cool completely. Let the cakes cool in their pans for 10 minutes. Carefully turn them onto wire racks, remove the parchment, and let them cool completely, about 1 hour. Do not frost warm layers.
Make the vanilla buttercream. Beat the softened butter for about 2 minutes until creamy. Gradually add the powdered sugar on low speed. Add the vanilla, salt, and ¼ cup (60 ml) heavy cream, then beat on medium-high for 2 to 3 minutes until fluffy. If the frosting is too stiff to spread cleanly, beat in additional cream 1 tablespoon (15 ml) at a time, using no more than the additional 2 tablespoons (30 ml).
Level and stack the cake. If necessary, trim pronounced domes from the cooled cakes with a serrated knife. Place the chocolate layer on a serving plate or cake board and spread about ¾ cup of buttercream evenly over it. Add the vanilla layer, another ¾ cup buttercream, and then the strawberry layer.
Apply a crumb coat. Spread a thin layer of buttercream over the top and sides to trap loose crumbs. Refrigerate the cake for 20 minutes, until the coating feels firm.
Finish the frosting. Cover the chilled cake with the remaining buttercream, smoothing the top and sides with an offset spatula. For a softer homemade finish, create gentle swirls instead of perfectly smooth sides.
Garnish and serve. If desired, decorate with the crushed freeze-dried strawberries and chocolate shavings. For cleaner slices, let the finished cake stand for about 10 minutes after its final chilling before cutting.

Kitchen-Tested Note

Measure the flour carefully. Too much flour is a common reason layer cakes turn out dry or heavy. For the most consistent result, weigh the 330 g rather than packing flour into measuring cups.
Keep the ingredients near room temperature. Butter, eggs, milk, and sour cream combine more evenly when they are not refrigerator-cold.
Do not overmix after adding flour. Excessive mixing develops gluten and can make the layers tougher instead of tender.

What Makes This Recipe Work

One base batter keeps the layers consistent. Dividing a single vanilla batter before adding chocolate and strawberry flavorings helps the three cakes bake with similar textures and heights.
Freeze-dried strawberries add concentrated flavor without excess moisture. They can be ground into a fine powder that blends directly into the batter without making it watery.
Cocoa powder creates a distinct chocolate layer. A small amount is enough to deepen the flavor while keeping the chocolate batter close in consistency to the other layers.
Sour cream helps keep the crumb tender. Its moisture and acidity contribute to a soft cake that holds up well when stacked.
Cooling before assembly improves stability. Completely cooled layers are easier to level, frost, and stack without melting the buttercream.

Make-Ahead and Storage Notes

Room temperature: The assembled cake can stand at cool room temperature for several hours while serving, but longer storage is better in the refrigerator because of the buttercream and moist cake layers.
Refrigerator: Store the frosted cake in a covered cake carrier or airtight container for up to 4 days. Bring individual slices toward room temperature before serving so the buttercream softens and the cake has a more tender texture.
Freezing: Unfrosted cake layers can be wrapped tightly in plastic wrap and then foil and frozen for up to 2 months. The assembled cake can also be frozen, preferably without the optional garnish. Freeze until firm, then wrap securely to protect it from freezer odors and drying.
Thawing: Thaw wrapped cake layers in the refrigerator overnight before unwrapping. A fully assembled frozen cake should also thaw gradually in the refrigerator.
Make-ahead: Bake the layers a day ahead, cool them completely, wrap them tightly, and keep them at room temperature overnight if your kitchen is cool, or refrigerate them. The buttercream can also be prepared ahead and refrigerated in an airtight container; let it soften at room temperature and beat it briefly before frosting.

Recipe Questions

Can I make this recipe ahead of time?

Yes. The cake layers can be baked one day before assembly. Cool them completely and wrap them tightly so they do not dry out. The finished cake can also be refrigerated overnight before serving.

Can I use fresh strawberries instead of freeze-dried strawberries?

Not as a direct one-for-one substitution. Fresh berries contain much more water and can make the strawberry batter too wet. A strawberry puree would require adjusting other ingredients to maintain the cake's structure.

Why did my cake layers turn out dense?

Overmeasuring the flour, using cold ingredients, or mixing the batter too long after adding the flour can all produce a denser crumb. Weigh the flour when possible and stop mixing as soon as the batter is uniform.

Can I bake the layers in 9-inch pans?

Three 9-inch pans can be used, but the layers will be thinner and will generally bake more quickly. Begin checking them several minutes earlier than the stated baking range.

How do I keep the layers from sliding while frosting?

Make sure the cakes are completely cool and the buttercream is thick enough to hold its shape. Applying and chilling a thin crumb coat before the final frosting also makes the stacked cake considerably easier to finish.
