1-First Step: Mise en Place and Prep Begin by preheating your oven to 350°F and greasing two 9-inch round cake pans with butter or a non-stick spray. Measure out all ingredients like 2 1/2 cups flour and 1 1/2 cups sugar to avoid rushing later. This preparation helps prevent any mix-ups and ensures your simple Funfetti cake recipe flows easily, especially if you’re adapting for dietary needs like using a gluten-free flour blend.

2-Second Step: Mixing the Dry Ingredients In a large bowl, whisk together 2 1/2 cups all-purpose flour, 1 tablespoon baking powder, and a pinch of salt at medium speed for about 30 seconds. This step evenly distributes the leavening for a consistent rise in your Funfetti birthday cake. If making a vegan version, check that your baking powder is plant-based to keep things simple and effective.

3-Third Step: Creaming and Combining Wet Ingredients In another bowl, beat 1 cup unsalted butter and 1 1/2 cups granulated sugar on high speed for 2-3 minutes until light and fluffy. Add 3 large eggs one at a time, mixing on low speed after each, then stir in 1 teaspoon vanilla extract and 1 cup whole milk gradually. For low-calorie options, substitute the butter with applesauce here to maintain moisture without over-mixing, which could deflate the sprinkles in your easy sprinkle birthday cake.

4-Fourth Step: Incorporating Sprinkles and Battery Assembly Gently fold in 1/2 cup rainbow sprinkles to the wet mixture using a spatula, taking care not to over-stir and break them. Combine the wet and dry mixtures by folding carefully on low speed for 1 minute until just blended, avoiding any deflating of the batter. If using egg substitutes for a vegan Funfetti birthday cake, fold them in at this stage for the best texture.

5-Final Step: Baking, Cooling, and Decorating Pour the batter evenly into your prepared pans and bake at 350°F for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack for full cooling, which takes about an hour. Once cool, frost with your favorite buttercream and decorate with extra sprinkles, adapting for gluten-free needs by ensuring all toppings are safe. This completes your how to make Funfetti birthday cake journey, ready for serving and enjoying.
