Ingredients You’ll Need

2 cups all-purpose flour: This is the base of your cake, lending it the right structure. For a lighter cake, consider using cake flour.
2 teaspoons baking powder: This leavening agent ensures your cake rises beautifully. Be sure it’s fresh for the best results.
¾ teaspoon salt: Enhances the flavor of the cake, balancing the sweetness.
1 cup unsalted butter, melted: Adds richness and moisture. Be sure to let it cool slightly before mixing.
1 ½ cups granulated sugar: Sweetness is key! Using quality sugar will make a significant difference.
4 large eggs: These add moisture and structure. Use eggs at room temperature for best incorporation.
1 teaspoon vanilla extract: This flavor enhances the cake; pure vanilla extract is preferred for depth.
1 cup buttermilk: Tenderizes the cake, results in a moist crumb. If you don’t have buttermilk, mix 1 cup of milk with a tablespoon of lemon juice or vinegar for a quick substitute.
1 cup rainbow sprinkles: These are the star of the show! Go for high-quality, nonpareil sprinkles for the best texture and color.
1 cup unsalted butter, softened: Used for the frosting, creating a smooth, creamy texture.
4 cups powdered sugar: This sweetens the frosting; sift for a smoother mix.
1 teaspoon vanilla extract: Adds a lovely flavor to the frosting, complementing the cake.
½ teaspoon salt: Balances out the sweetness of the frosting.
2-5 tablespoons heavy whipping cream: This will help achieve the desired frosting consistency.
½ cup sprinkles plus more for topping: Use these to finish off the cake and make it shimmer!

How to Make Homemade Funfetti Cake

Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to ensure your cake doesn’t stick.
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. Set this mixture aside.
Combine Butter and Sugar: In a large mixing bowl, beat 1 cup melted unsalted butter and 1 ½ cups granulated sugar on medium speed until smooth and creamy.
Add Eggs and Vanilla: Mix in the 4 large eggs one by one, making sure each one is fully incorporated before adding the next. Then add 1 teaspoon vanilla extract.
Incorporate Buttermilk and Dry Ingredients: Alternating between the dry flour mixture and 1 cup buttermilk, add them to the butter mixture. Start and end with the buttermilk, mixing on medium-high speed after each addition until combined. Scrape down the bowl as needed.
Stir in Sprinkles: Gently fold in 1 cup rainbow sprinkles, making sure they’re evenly distributed throughout your batter.
Bake: Pour the batter into the prepared pan and smooth the top. Bake in your preheated oven for 30-40 minutes, or until a toothpick inserted comes out clean.
Cool Cake: Let the cake cool completely in the pan before frosting. Patience is key here to avoid a melty mess!
Prepare the Frosting: In a mixing bowl, beat 1 cup softened unsalted butter until creamy. Gradually add 4 cups powdered sugar, then mix in 1 teaspoon vanilla extract and ½ teaspoon salt.
Achieve Desired Consistency: Add 2 tablespoons of heavy whipping cream and mix until smooth, adjusting with more cream as needed to reach your preferred consistency.
Frost and Top with Sprinkles: Frost your cooled cake with the buttercream, using an offset spatula for an even layer. Top with ½ cup sprinkles for that beautiful, festive look.
Serve & Enjoy: Slice and serve! This cake can also be transformed into 24 cupcakes, two 9-inch round cakes, or three 8-inch round cakes.

Storing & Reheating

To keep your Homemade Funfetti Cake fresh, store it loosely covered at room temperature for up to 2 days. If you need a longer-term option, refrigerate it in an airtight container for up to a week. You can also freeze slices wrapped tightly in plastic wrap and aluminum foil for up to three months. When you’re ready to enjoy it again, simply thaw in the refrigerator or on the counter. Reheat a slice in the microwave for about 15-20 seconds if you prefer it warm. Just know that the texture may change slightly after freezing, but a quick warm-up can refresh it.

Chef’s Helpful Tips

Room Temperature Ingredients Matter: Ensure your eggs and butter are at room temperature for a smoother batter that blends well.
Avoid Overmixing: Once you add the flour, mix just until combined to prevent a dense cake.
Bake Evenly: Rotate the pan halfway through baking for even heat distribution.
Flavor Boost: An extra splash of vanilla or almond extract can be a delightful twist!
Experiment: Feel free to use different colored sprinkles or add chocolate chips for a variation that’s just as fun.
