1-First Step: Start by pulling together all your ingredients and tools to ensure a smooth baking process. Measure out items like 9 tablespoons of softened unsalted butter and 3 cups of granulated sugar, then let them sit at room temperature for easy mixing.

2-Second Step: Preheat your oven to 350 degrees Fahrenheit and prepare your baking pans by greasing and lining them with parchment paper. This step helps the homemade Funfetti cake release easily after baking.

3-Third Step: In a large bowl, cream the 9 tablespoons of unsalted butter with 3 cups of granulated sugar until it’s light and fluffy, which takes about 5 minutes with a mixer. Add 1 cup of neutral cooking oil and 4 teaspoons of vanilla extract, mixing until well combined for that signature flavor in your simple Funfetti cake from scratch.

4-Fourth Step: In another bowl, whisk together 4 cups plus 2 tablespoons of all-purpose flour, 4½ teaspoons of baking powder, and 1½ teaspoons of table salt. Gradually add this dry mix to the wet ingredients, alternating with 1½ cups of milk to keep the batter smooth.

5-Fifth Step: In a separate clean bowl, whip the 9 large egg whites until they form stiff peaks, which might take 2-3 minutes. Gently fold them into the batter along with ½ cup of sprinkles to add air and keep the texture light for this easy homemade Funfetti cake.

6-Sixth Step: Pour the batter into your prepared pans, dividing it evenly for a two-layer cake. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean, adjusting time if you’re using a different pan size for dietary adaptations.

7-Seventh Step: Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. While they cool, prepare the buttercream by beating 1 pound of softened unsalted butter with 6 cups of powdered sugar, ¼ teaspoon of salt, 6 tablespoons of heavy cream, and 2 teaspoons of princess emulsion or vanilla extract.

8-Eighth Step: Once cooled, spread the buttercream between the layers and over the top and sides of the cake. For variations, add more sprinkles or adapt for vegan options by using plant-based butter. This homemade Funfetti cake recipe serves as a great base for custom flavors.

9-Ninth Step: Let the cake set for about 30 minutes before serving to ensure the frosting firms up. Slice and enjoy, knowing this easy homemade Funfetti cake can be tailored for gluten-free needs by swapping the flour.
