Ingredients You’ll Need

2 cups (248g) all-purpose flour: Provides structure to the cake. For best results, use a kitchen scale for accuracy.
2 teaspoons baking powder: Helps the cake rise. Make sure it’s fresh for maximum effect.
¾ teaspoon salt: Enhances the other flavors in the cake.
1 cup (226g) unsalted butter, melted: Adds richness. Always use unsalted to control the saltiness of your cake.
1 ½ cups (300g) granulated sugar: Sweetens the cake and contributes to its tender crumb.
4 large eggs: Makes the cake light and fluffy. Room temperature eggs mix better.
1 teaspoon vanilla extract: Essential for flavor. Always choose pure vanilla extract for the best taste.
1 cup (237ml) buttermilk: Ensures a moist cake. If you don’t have buttermilk, mix 1 tablespoon of vinegar or lemon juice into regular milk and let it sit for 5 minutes.
1 cup (225g) rainbow sprinkles: The star of the show! Make sure to use jimmies or nonpareils, as others may bleed into the batter.
1 cup (226g) unsalted butter, softened: Needed for the frosting; make sure it’s softened to room temperature for easy mixing.
4 cups (452g) powdered sugar: Sweetness and body for the frosting.
1 teaspoon (15 ml) vanilla extract: For flavor in the frosting.
½ teaspoon salt: Balances the sweetness of the frosting.
2-5 tablespoons (30-75ml) heavy whipping cream: Adds creaminess to the frosting. Adjust based on your desired consistency.
½ cup (112g) sprinkles plus more for topping: Extra sprinkles for that fun finishing touch!

How to Make Homemade Funfetti Cake

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to ensure your cake comes out easily.
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups (248g) all-purpose flour, 2 teaspoons baking powder, and ¾ teaspoon salt. Set this mixture aside.
Cream Butter and Sugar: In a large bowl, combine 1 cup (226g) melted unsalted butter and 1 ½ cups (300g) granulated sugar. Mix on medium speed until smooth and creamy.
Incorporate Eggs and Vanilla: Add in the 4 large eggs, one at a time, mixing well after each addition, followed by 1 teaspoon of vanilla extract.
Combine Wet and Dry Ingredients: Pour in 1 cup (237ml) buttermilk alternately with the dry flour mixture. Mix on medium-high speed until just combined. Remember to scrape down the sides of the bowl for even mixing. Finally, gently fold in 1 cup (225g) rainbow sprinkles.
Bake: Pour the batter into the prepared pan and spread it out evenly. Bake for 30-40 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely before frosting.
Make the Frosting: Beat 1 cup (226g) softened unsalted butter in a bowl until creamy using a hand or stand mixer. Gradually add in the 4 cups (452g) powdered sugar, one cup at a time, until a crumbly mixture forms. Mix in 1 teaspoon vanilla extract, ½ teaspoon salt, and 2 tablespoons heavy cream. Adjust the consistency with more cream until smooth. Fold in sprinkles for a festive finish.
Frost and Serve: Once the cake is cool, frost generously with the sprinkles-infused frosting. Top with additional sprinkles for a cheerful touch. This cake can be stored loosely covered for up to 2 days.

Variations

You can transform this recipe into 24 cupcakes or use two 9-inch round pans for a layered cake.
For a smaller batch, halve the ingredients for about a dozen cupcakes.

Storing & Reheating

To store Homemade Funfetti Cake, keep it at room temperature in an airtight container for up to two days. If you want to extend its life, refrigerate it for up to 5 days, wrapped well to prevent drying out. You can also freeze slices for up to three months; just wrap them tightly in plastic wrap and then aluminum foil. When you’re ready to enjoy, simply thaw at room temperature. Note that while freezing keeps the cake tasty, the texture may change slightly, so refresh it with a quick frosting application or serving alongside whipped cream.

Chef’s Helpful Tips

Always ensure your baking powder is fresh; a simple test is to add a teaspoon to warm water—if it bubbles, it’s good to go!
For the fluffiest cake, use room temperature eggs and butter; this helps them blend better, leading to a lighter cake.
Don’t overmix your batter once you add the flour; doing so can lead to a dense texture.
If using colored sprinkles, be cautious during mixing so they don’t bleed too much into the cake.
Feel free to customize your frosting—add compressed fruit or flavored extracts for a unique twist.

Homemade Funfetti Cake is not just a treat; it’s an experience wrapped in sweet nostalgia. With its vibrant colors and delightful flavor, it captures the essence of joy in every slice. Don’t hesitate to add your unique twist to this recipe; perhaps swap in some chocolate sprinkles or experiment with flavored frostings. The possibilities are endless! Enjoy cooking and making beautiful memories with this delightful cake!

Recipe FAQs

Can I make this cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Just ensure that it’s a measure-for-measure type for the best results.

How can I add more flavor to the cake?

You can enhance the flavor by adding citrus zest, like lemon or orange, or even incorporating almond extract along with the vanilla. It adds an extra layer of deliciousness!

How do I ensure my cake is moist?

Using buttermilk is key to achieving moisture, but ensure you don’t overbake the cake. Keep an eye on it, especially towards the end of the baking time.

Can I use milk instead of buttermilk?

Yes! If buttermilk isn’t available, mix 1 tablespoon of vinegar or lemon juice with regular milk and let it sit for about 5 minutes. This will slightly sour the milk, giving a similar effect to buttermilk.
