Step-by-Step Instructions

Creating Easy Neapolitan Sheet Cake is a breeze if you follow these simple steps:

  1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 13×18-inch baking sheet.
  2. Mix Dry Ingredients: In a large bowl, combine the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk together until fully mixed.
  3. Combine Wet Ingredients: In another bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract until well combined.
  4. Combine Mixtures: Gradually stir the wet mixture into the dry ingredients until just combined.
  5. Add Boiling Water: Carefully stir in the boiling water until the batter is smooth and well blended; it will be thin.
  6. Pour Batter: Pour the batter into the prepared baking sheet, spreading it evenly.
  7. Bake the Cake: Place it in the preheated oven and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
  8. Cool the Cake: Once baked, remove the cake and let it cool in the pan for about 15 minutes. Afterward, transfer it to a wire rack to cool completely.
  9. Prepare Frosting: Beat the softened butter until creamy. Gradually add the powdered sugar, mixing until smooth. Divide the frosting into three bowls.
  10. Color the Frosting: In one bowl, mix in the vanilla extract for vanilla frosting. In the second bowl, add strawberry puree and food coloring for a pink hue. In the third bowl, leave it as chocolate frosting, adding cocoa if desired.
  11. Frost the Cake: Once the cake is cool, spread the chocolate frosting on the first third of the cake, vanilla frosting in the middle, and strawberry frosting on the last third. Use a spatula to smooth it out evenly.

How to Serve

To create a memorable serving experience for your Easy Neapolitan Sheet Cake, consider the following tips:

  1. Presentation: Serve the cake directly from the baking sheet for a laid-back look, or transfer it to a decorative cake stand for a more elegant display.

  3. Slice Size: Cut into generous squares, encouraging your guests to savor each bite while leaving room for seconds.
  4. Beverage Pairing: Pair this dessert with coffee, tea, or milk to complement the flavors and satisfy different taste preferences.

Additional Tips

  • Use Fresh Ingredients: Using fresh eggs, quality vanilla extract, and ripe strawberries for the puree will elevate the flavor of your Easy Neapolitan Sheet Cake.
  • Mix Thoroughly: Make sure to mix the dry and wet ingredients until just combined. Over-mixing can lead to a dense cake.
  • Level the Cake: After baking, if your cake has risen unevenly, gently level it with a serrated knife. This ensures an even frosting surface.
  • Add Sprinkles: For an extra festive touch, sprinkle colorful jimmies or confetti sprinkles on top of the frosting before serving.
  • Experiment with Frosting: You can also try adding a layer of whipped cream on top for a lighter feel or mix in chocolate chips for added texture.

  1. Chocolate Chip Swirl: Fold in mini chocolate chips into the batter before baking for an extra chocolatey bite.

  1. Cupcake Version: Bake the batter in cupcake liners for individual servings. Adjust baking time to about 18-20 minutes.
  1. Layering Flavors: Incorporate a layer of cheesecake filling made from cream cheese, sugar, and vanilla for a creamy twist.
  1. Vegan Option: Substitute the eggs with flaxseed meal and use non-dairy milk and vegetable oill to create a vegan version.
