Ingredients You’ll Need

2 cups all-purpose flour: This is the base of your cake, providing structure. For a gluten-free version, consider using a 1:1 gluten-free flour blend.
2 teaspoons baking powder: This ingredient helps the cake rise and become fluffy. Always check expiration dates for best results!
¾ teaspoon salt: A touch of salt enhances the sweetness of the cake. Don’t skip this crucial element!
1 cup unsalted butter, melted: This adds moisture and a rich flavor. For a lighter option, you can substitute half of the butter with applesauce.
1 ½ cups granulated sugar: Granulated sugar sweetens the cake, giving it that delightful taste we love.
4 large eggs: Essential for binding the ingredients and providing structure. Make sure they are at room temperature for better mixing.
1 teaspoon vanilla extract: Pure vanilla brings depth to the flavor. Try to use pure rather than imitation for the best taste.
1 cup buttermilk: It keeps the cake moist and tender. You can substitute with plain yogurt or milk mixed with lemon juice if you don’t have buttermilk.
1 cup rainbow sprinkles: These add fun pops of color and sweetness to each slice. Ensure they’re not the chocolate-coated kind for best results in baking.
1 cup unsalted butter, softened: Used for making the frosting creamy and rich.
4 cups powdered sugar: This creates a sweet, fluffy frosting. Sift it first to avoid lumps.
1 teaspoon vanilla extract: For flavoring the frosting, enhancing its sweetness.
½ teaspoon salt: Balances the sweetness of the frosting and enhances the flavor.
2-5 tablespoons heavy whipping cream: To achieve the right frosting consistency, adjust based on your preferred thickness.
½ cup sprinkles plus more for topping: Always a joyful addition, making your cake festive!

How to Make Homemade Funfetti Cake

Preheat and Prepare: Preheat your oven to 350°F. Grease and flour a 9×13-inch baking pan to ensure the 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 for later.
Cream Butter and Sugar: In a large bowl, beat together 1 cup melted unsalted butter and 1 ½ cups granulated sugar on medium speed until smooth and creamy. This should take about 2-3 minutes.
Add Eggs and Vanilla: Incorporate the 4 large eggs one at a time, ensuring each is well mixed in before adding the next. Then, add 1 teaspoon vanilla extract and mix until fully combined.
Combine Wet and Dry Ingredients: Add the buttermilk alternately with the flour mixture. Start and end with buttermilk, mixing on medium-high speed until just combined. Be careful not to overmix — a few lumps are okay! This is the moment to gently fold in 1 cup of rainbow sprinkles.
Bake the Cake: Pour the batter into the prepared pan. Bake for 30-40 minutes or until a toothpick comes out clean when inserted into the center. Keep an eye on it towards the end for a perfectly golden top!
Cool the Cake: Allow the cake to cool completely in the pan before frosting. Patience is key here for a smooth frosting application!
Make the Frosting: Beat 1 cup softened unsalted butter on medium speed until creamy. Gradually add the 4 cups powdered sugar, mixing until a crumbly mixture forms. Next, mix in 1 teaspoon vanilla extract and ½ teaspoon salt. Add 2 tablespoons heavy whipping cream and stir until you reach the desired smoothness, adding more cream as necessary. Last, fold in ½ cup sprinkles for that extra fun.
Frost the Cake: Spread the frosting generously over the cooled cake using a spatula, and don’t forget to sprinkle some extra sprinkles on top for that festive touch. Your cake is ready to impress!
Enjoy or Store: This recipe makes enough for 24 cupcakes, or you can scale it down into two 9-inch round cakes or three 8-inch rounds if you prefer.

Storing & Reheating

To keep your Homemade Funfetti Cake fresh, store it loosely covered at room temperature for up to 2 days. If you need to store it longer, transfer it to an airtight container in the refrigerator for up to a week. Alternatively, you can freeze it in well-wrapped portions for up to 3 months. When you’re ready to enjoy your cake, simply bring it to room temperature, and if desired, give it a quick re-frosting or a dollop of whipped cream to refresh its taste.

Recipe FAQs

Can I use different types of sprinkles?

Absolutely! You can play around with the sprinkles you use. Just avoid chocolate-coated sprinkles since they can melt into the batter. Fun, colorful sprinkles or themed sprinkles can really enhance the festive feel of the cake!

Can I make this cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free 1:1 baking flour. Be sure to check that all your other ingredients, like baking powder and buttermilk, are gluten-free as well. The texture may differ slightly, but you’ll still have a delicious cake.

What can I use instead of buttermilk?

If you don’t have buttermilk on hand, you can easily make your own by combining 1 cup of milk with 1 tablespoon of white vinegar or lemon juice. Let it sit for about 5-10 minutes until it thickens. This works beautifully in baking!

How can I reduce the sweetness of the frosting?

If you’re looking to cut back on sweetness, you can reduce the powdered sugar by half and replace it with more butter or, for a tangy twist, add a bit of cream cheese. Keep in mind that this will alter the texture slightly but will yield a deliciously balanced frosting!
