Mastering Funfetti Cake: How-To

Step 1: Prepare Your Pans
Start by preheating your oven to 350°F (175°C). Grease your two 9-inch round cake pans with butter or non-stick spray and dust with a little cake flour to prevent sticking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the cake flour, baking powder, and salt. Set this mixture aside while you prepare the wet ingredients.
Step 3: Cream the Butter and Sugar
In a large bowl, with an electric mixer, beat the unsalted butter and granulated sugar together until light and fluffy. This will take about 3-4 minutes.
Step 4: Add the Wet Ingredients
Add the egg whites, whole milk, and vanilla extract to the butter and sugar mixture. Beat until combined, scraping down the sides of the bowl as needed.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix. Gently fold in the rainbow jimmies, making sure they’re evenly distributed.
Step 6: Bake the Cakes
Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for about 10 minutes, then invert them onto a cooling rack to cool completely.
Step 7: Make the Frosting
In a large bowl, beat the unsalted butter for the frosting until creamy. Gradually add the sifted confectioners’ sugar, mixing on low speed until combined. Add the salt, vanilla extract, and just enough milk or cream to reach your desired consistency. Beat until fluffy.
Step 8: Frost the Cake
Once the cake layers are completely cool, place one layer on a serving plate. Spread a generous layer of frosting on top. Place the second layer on top and use the remaining frosting to cover the top and sides of the cake. Decorate with additional sprinkles as desired.
Dietary Swaps & Alternatives

- Gluten-Free: Substitute the cake flour with a gluten-free all-purpose flour blend.
- Milk Alternatives: Use almond milk, coconut milk, or oat milk in place of whole milk.
- Egg-Free: Replace egg whites with aquafaba (the liquid from canned chickpeas) or a commercial egg replacer.
- Lower Sugar: Use a sugar substitute that measures cup-for-cup to reduce sugar content.
Problems & Prevention
If your Funfetti Cake turns out dense, it might be due to overmixing the batter. Mix just until combined to keep it light and fluffy. Ensure that all ingredients are at room temperature for the best texture. If the cake sticks to the pan, make sure to grease and flour the pans properly before pouring in the batter.
How to Store & Reheat
- Storing: Keep uneaten cake covered at room temperature for up to 3 days, or refrigerate for up to a week.
- Freezing: Wrap the cooled cake layers tightly in plastic wrap and freeze for up to 3 months.
- Reheating: If the cake is frozen, allow it to thaw in the refrigerator overnight before serving.
Common Qs About Funfetti Cake

Can I make this cake in advance?
Yes! You can bake the cake in advance and assemble it the day of your celebration. Just make sure to store the layers properly.
