Ingredients You'll Need

Funfetti Cake Ingredients

• Cake flour. Produces a soft, tender cake crumb. I prefer using unbleached cake flour.
• Baking powder and baking soda. Leavening agents allow the cake to rise and have a fluffy texture.
• Salt. Added to the batter to enhance the flavors of other ingredients in the cake.
• Butter. Use unsalted butter to control the amount of salt that goes into the batter. It’s important to use softened butter. It should be slightly firm to the touch and not greasy, yet leave the impression of your finger when you press into it.
• Granulated sugar. Adds sweetness to the cake. When the sugar and butter creams together, air is incorporated into the batter, which creates the perfect light and tender cake.
• Egg whites. Using egg whites creates a lighter-colored cake batter with a light, airy crumb. If you prefer whole eggs, substitute 2 large eggs for the 3 large egg whites.
• Vanilla. Always select a good quality pure vanilla extract for the best flavor.
• Sour cream. Adds moisture and richness to the cake. The acidity in sour cream helps create a softer and more tender cake. It also activates the baking soda. Ensure your sour cream is at room temperature to incorporate with the other ingredients into a smooth batter.
• Milk. Also adds moisture and richness to the cake. Milk is a binding ingredient that brings everything together. Use at room temperature, and if possible, use whole milk.
• Rainbow sprinkles. Adds a color element creating a nostalgic funfetti cake.

Cream Cheese Frosting Ingredients

• Butter. Adds a rich flavor to the frosting. Use unsalted butter brought to room temperature.
• Cream cheese. Use block cream cheese. It has a dense, firm texture, perfect for making creamy frosting. A tub of whipped cream cheese has too much air incorporated into it and is not ideal for frosting. Bring cream cheese to room temperature to create a smooth and creamy frosting.
• Powdered sugar. Sweetens the buttercream and dissolves into a smooth consistency.
• Vanilla. The flavoring in the frosting.
• Heavy cream. Thins out the buttercream to a spreadable consistency. Add more or less depending on your desired consistency. You can substitute it with milk.

What Sprinkles Should I Use?

Not all sprinkles are created equal when it comes to baking a cake. For decorating purposes, you can use any sprinkle you like. But when you are making the batter, sprinkles (aka jimmies) are the way to go. They offer pretty colors that won’t bleed into the batter.

I don’t recommend using nonpareils, the tiny rainbow sugar balls. Their color will bleed into your cake batter.

Recipe Substitutions

• All-purpose flour. If you don’t have cake flour, you can make your own. Measure 1 ½ cups of all-purpose flour, and replace 3 tablespoons with 3 tablespoons of cornstarch. Sift together to combine evenly.
• Buttermilk. Replace the sour cream and whole milk with 160 g (⅔ cup) buttermilk at room temperature.

Equipment & Tools

• Digital kitchen scale or measuring cups. Using a scale will give you the most accurate measurements for consistent results.
• 8x8 square baking pan.
• Parchment paper. Line the bottom of your pan to prevent the cake from sticking.
• Sifter or fine mesh sieve. Used to sift the dry ingredients together.
• Medium bowl. Sift the dry ingredients into the bowl.
• Large bowl. Used to mix the cake batter. If using a stand mixer, use the accompanying mixing bowl.
• Mixer. You’ll need a mixer to make the cake batter and cream cheese frosting. You can use a handheld or stand mixer fitted with a paddle attachment.
• Rubber spatula.
• Offset spatula. Helpful for spreading the frosting over the cooled cake.

Step-By-Step Instructions

Before you begin: Preheat the oven to 350°F/177°C. Grease and flour an 8x8 square pan, line the bottom with parchment paper allowing extra to hang over the sides for easy lifting out of the pan.  Read the recipe from start to finish.

Recipe Tips & Tricks

Snack cakes are easy and fun to make. As a trained pastry chef, I follow these guidelines to bake beautiful cakes with the perfect texture.

• Weigh your ingredients. Using a scale to measure your ingredients gives you the most accurate and consistent results.
• Use room temperature ingredients. Bringing your ingredients to room temperature helps to create a smooth batter that is evenly blended. This promotes a consistent texture and even baking.
• Sift the cake flour. Breaking up any lumps will allow the dry ingredients to combine smoothly with the wet ingredients.
• Cream butter and sugar. Beat together until light and fluffy. Don’t skip this step because it will incorporate air into the batter for a light and tender cake.
• Cool cake completely. Frost a completely cooled funfetti snack cake to prevent the cream cheese frosting from melting.

What Frostings Go With Funfetti Cake?

Essentially funfetti cake is a vanilla-based white cake batter mixed with rainbow sprinkles. It’s a versatile cake that pairs well with many frostings. Here are some of my favorite frostings to pair this cake with:

• Vanilla buttercream. Double the frosting recipe from these mini funfetti cupcakes.
• Chocolate fudge frosting. For a decadent combination, use fudge frosting from this fudge cake.
• Strawberry cream cheese frosting. In the warm summer months, I love using the frosting from these strawberry cupcakes.

Storage & Freezing Tips

• Refrigerated. Store leftover funfetti cake in an airtight container for up to 3 or 4 days in the refrigerator.
• In the freezer. Wrap the leftover cake with plastic wrap and place it in an airtight container. Store in the freezer for up to 3 months. Allow to thaw in the refrigerator overnight before serving.
• Make ahead. Wrap the completely cooled cake in plastic wrap and store it at room temperature overnight. Make the frosting up to 1 week in advance and store it in the refrigerator. Bring to room temperature before decorating the cake and re-whip the frosting using a mixer.

Note: I don’t recommend freezing a whole decorated cake. For the best texture, freeze the cake and decorate it up to 1 day before serving.
