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
- Begin by preheating your oven to 350°F (175°C). While it’s heating up, take your three 8-inch round cake pans and grease them thoroughly with unsalted butter. Then, line the bottom of each pan with parchment paper to ensure easy removal post-baking.
- In a medium-sized mixing bowl, sift together the gluten-free all-purpose flour, baking powder, baking soda, and salt. Whisk these ingredients until well combined.
- In a large mixing bowl, beat the softened unsalted butter along with granulated sugar using a hand mixer or stand mixer until it becomes light and fluffy.
- Add the room temperature eggs one at a time, mixing thoroughly after each addition. Next, stir in the pure vanilla extract.
- Gradually incorporate the dry ingredient mixture into your butter-sugar-egg mixture, alternating with buttermilk. Start and end with the flour mixture, mixing until just combined.
- Gently fold in the gluten-free rainbow sprinkles with a spatula.
- Divide the mixture evenly among the prepared cake pans and place them in the preheated oven. Bake for 22-25 minutes or until a toothpick inserted in the center comes out clean.
- Once baked, let the cakes cool in their pans for about 10 minutes.
- For the frosting, in a clean mixing bowl, beat the softened butter until it turns creamy. Gradually add powered sugar, pouring in the vanilla extract and heavy cream for moisture.
- Once your cake layers are completely cool, place the first layer on a serving plate and generously spread a layer of frosting on top. Repeat with the second layer and finally, cover the entire cake with the remaining frosting, garnishing with extra rainbow sprinkles.
