Description

A festive homemade happy birthday cake with fluffy vanilla layers, creamy buttercream frosting, and rainbow sprinkles. Gluten-free friendly and perfect for parties or family celebrations.

Ingredients

Scale

2 ½ cups gluten-free all-purpose flour (with xanthan gum included)
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup unsalted butter, softened
1 ½ cups granulated sugar
4 large eggs, room temperature
2 teaspoons pure vanilla extract
1 cup buttermilk (or whole milk + 1 tablespoon vinegar)
½ cup rainbow sprinkles (gluten-free certified)
1 cup unsalted butter, softened (for frosting)
4 cups powdered sugar
2 teaspoons vanilla extract (for frosting)
2–3 tablespoons heavy cream
Extra rainbow sprinkles for decorating

Instructions

Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
In a medium bowl, whisk together gluten-free flour, baking powder, baking soda, and salt.
In a large mixing bowl, beat butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
Gradually add dry ingredients to the wet mixture, alternating with buttermilk, beginning and ending with the flour mixture.
Fold in the rainbow sprinkles gently to avoid color bleeding.
Divide the batter evenly among the prepared pans and bake for 22–25 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool in pans for 10 minutes before transferring to a wire rack to cool completely.
For the frosting, beat softened butter until creamy. Gradually add powdered sugar, vanilla, and cream until light and fluffy.
Frost cooled cake layers, stack, and cover the outside with frosting. Garnish generously with sprinkles.

Notes

Use room temperature eggs and butter for best results.
Do not overmix once flour is added to keep the cake fluffy.
Always use jimmies sprinkles instead of nonpareils to prevent color bleeding.
For dairy-free, substitute vegan butter and almond milk with vinegar.
Chill cake layers before frosting for easier assembly.
