Ingredients You’ll Need

2 cups all-purpose flour: This forms the base of your cake. Be sure to use a good quality flour for the best texture.
2 teaspoons baking powder: This is crucial for the cake’s rise; it helps create that light and fluffy texture.
¾ teaspoon salt: Just a bit enhances the flavor, balancing the sweetness.
1 cup unsalted butter, melted: Using unsalted butter lets you control the salt in the cake, delivering a rich flavor.
1 ½ cups granulated sugar: This is where the sweetness comes from! It also contributes to a moist crumb.
4 large eggs: Eggs provide moisture, richness, and help bind everything together.
1 teaspoon vanilla extract: Adds aromatic sweetness; pure vanilla extract is always best.
1 cup buttermilk: This is key for tenderness; it reacts with the baking powder to create a delightful crumb.
1 cup rainbow sprinkles: These not only add texture but also create that classic funfetti appearance.
1 cup unsalted butter, softened: This forms the base for your decadent frosting, so it needs to be soft for a smooth mix.
4 cups powdered sugar: Essential for sweetness and structure in your frosting; sifted is best for a smooth finish.
1 teaspoon vanilla extract: Use again for extra flavor in your frosting!
½ teaspoon salt: Added again to ensure a balanced sweetness in the frosting.
2-5 tablespoons heavy whipping cream: Adjust to achieve your desired frosting consistency.
½ cup sprinkles plus more for topping: These add that final festive touch!

How to Make Homemade Funfetti Cake

Preheat the Oven: Set your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to prevent sticking.
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.
Cream Butter and Sugar: In a large bowl, beat together 1 cup melted unsalted butter and 1 ½ cups granulated sugar using a hand or stand mixer on medium speed until the mixture is smooth and creamy.
Add Eggs and Vanilla: Mix in 4 large eggs one at a time, then blend in 1 teaspoon of vanilla extract. This step helps achieve a fluffy texture.
Combine Wet and Dry Ingredients: Gradually add in the buttermilk (1 cup) alternating it with the dry ingredients. Start and end with buttermilk while mixing on medium-high speed. Don’t forget to scrape down the sides of the bowl! Gently fold in 1 cup rainbow sprinkles.
Bake the Cake: Pour the batter into the prepped pan and bake in the oven for 30-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely before frosting.
Prepare the Frosting: In a large mixing bowl, beat 1 cup softened unsalted butter until creamy. Gradually add 4 cups powdered sugar one cup at a time until the mixture is crumbly. Add in 1 teaspoon vanilla extract and ½ teaspoon salt. Mix in 2 tablespoons of heavy whipping cream and adjust until you reach a smooth, spreadable consistency. Stir in sprinkles.
Frost the Cake: Spread the frosting evenly over the cooled cake, using an offset spatula for ease. Top with an extra sprinkle of colorful sprinkles for decoration. Store loosely covered for up to 2 days.

Alternative Bakers’ Note

If you want to make cupcakes or layered cakes, this batch yields great results as well! You can easily make 24 cupcakes or two 9-inch round cakes, giving you flexibility for any occasion.

Storing & Reheating

To store your homemade funfetti cake, keep it loosely covered at room temperature for up to 2 days. For longer storage, refrigerate the cake in an airtight container for about a week. If you need to freeze it, wrap well with plastic wrap and aluminum foil, and it will keep well for up to three months. When you’re ready to enjoy, allow it to thaw at room temperature for a few hours. The texture might change slightly, but a quick zap in the microwave for 10-15 seconds can refresh its moisture.

Chef’s Helpful Tips

Avoid Overmixing: When adding the flour mix, blend just until combined to keep the cake tender.
Ingredient Temperatures Matter: Ensure that your eggs are at room temperature for better emulsification and fluffiness.
Don’t Skip the Cooling: Always let the cake cool completely before frosting to prevent melted frosting!
Consistency Check: If your frosting feels too thick, add heavy cream a tablespoon at a time until it reaches the desired smoothness.

There’s a good reason this homemade funfetti cake has been a staple celebrating life’s special moments! Its delightful tenderness paired with vibrant bursts of sweetness from the sprinkles creates an inviting treat that everyone will love. Plus, it’s super simple to make! Feel free to experiment with flavors or types of sprinkles; no two cakes need to be the same. Enjoy making this fantastic dessert that is sure to spread joy!

Recipe FAQs

Can I use cake flour instead of all-purpose flour?

Yes! If you prefer a lighter, fluffier cake, you can substitute cake flour for all-purpose flour. It may reduce the amount you need slightly, so keep an eye on the batter’s consistency.

How can I make this cake gluten-free?

To make a gluten-free homemade funfetti cake, simply substitute the all-purpose flour with a 1:1 gluten-free baking blend. Ensure other ingredients are labeled gluten-free as necessary.

What can I use instead of buttermilk?

If you don’t have buttermilk on hand, you can easily make a substitute by combining 1 cup of milk (whole or low-fat) with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5-10 minutes before using.

How long does this cake last?

When stored properly, homemade funfetti cake can last up to 2 days at room temperature or about a week in the fridge. If frozen, it can last for up to three months.
