Creating Neapolitan Cupcakes is a fun and engaging process. Follow these simple steps to ensure delicious results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Prepare a cupcake pan with liners.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, cocoa powder, baking powder, and salt.
3. Combine Wet Ingredients: In another bowl, beat the eggs, sugar, vegetable oil, milk, and vanilla extract until smooth.
4. Combine Dry and Wet Ingredients: Gradually add the dry mixture to the wet mixture, stirring until just combined.
5. Add Strawberry Puree: Gently fold in the strawberry puree to half of the batter, creating a pink layer.
6. Fill the Cupcake Liners: In the cupcake liners, add a layer of chocolate batter, followed by a layer of strawberry batter.
7. Bake: Place the pan in the oven and bake for 20-25 minutes, or until a toothpick comes out clean.
8. Cool Completely: Once baked, remove from the oven and allow cupcakes to cool in the pan for 10 minutes, then transfer to a wire rack.
9. Prepare Frosting: In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar and heavy cream, mixing until fluffy. Divide the frosting into thirds and add food coloring to create pink and yellow shades.
10. Frost the Cupcakes: Frost each cupcake starting with chocolate on the bottom, vanilla in the middle, and strawberry on top. Create a swirl effect for an eye-catching presentation.
