Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

All-purpose flour
Baking powder
Salt
Unsalted butter (softened)
Granulated sugar
Eggs
Vanilla extract
Whole milk
Gel food coloring (red, orange, yellow, green, blue, and purple)
Sprinkles or small candies (for the piñata filling)
Buttercream frosting (store-bought or homemade)

Directions

Prepare the cake batter: Preheat the oven to 350°F (175°C). Grease and line six 6-inch round cake pans. In a large bowl, whisk together flour, baking powder, and salt. In a separate bowl, cream butter and sugar until light and fluffy. Beat in eggs one at a time, then add vanilla extract.
Combine and divide batter: Gradually mix the dry ingredients into the wet ingredients, alternating with milk. Once the batter is smooth, divide it evenly into six bowls.
Color each layer: Tint each bowl of batter with a different gel food coloring—red, orange, yellow, green, blue, and purple—stirring until fully blended.
Bake the layers: Pour each colored batter into the prepared pans and bake for about 15–20 minutes or until a toothpick inserted comes out clean. Let the layers cool completely.
Assemble the cake: Level the cake layers if needed. Use a round cutter or knife to remove the center from four of the six layers (leave the top and bottom layers whole). Begin stacking: place one whole layer on the bottom, followed by the cut-out layers, spreading frosting between each. Fill the hollow center with sprinkles or small candies.
Top and frost: Add the final whole cake layer on top to seal the piñata filling. Cover the entire cake with a thin crumb coat of frosting, chill briefly, then apply the final layer of buttercream. Decorate as desired.

FAQs

What is a piñata cake?

A piñata cake is a layered cake with a hidden center filled with candies or sprinkles that spill out when the cake is cut, mimicking the surprise of a traditional piñata.

Can I use boxed cake mix instead of homemade?

Yes, you can use your favorite boxed white or vanilla cake mix. You’ll need enough batter for six 6-inch layers, so plan accordingly.

What kind of candies work best for the filling?

Small, dry candies like M&Ms, chocolate chips, jelly beans, or rainbow sprinkles work best. Avoid sticky or melt-prone fillings.

Do I need special tools to make this cake?

You don’t need any special tools, but round cookie cutters or a paring knife can help create a neat cavity for the candy center. A cake turntable and offset spatula can also assist in smooth frosting.

Use a serrated knife or cake leveler to trim the tops of each layer before stacking. This ensures stability and even frosting application.
