Making Quarter Funfetti Sheet Cake

This recipe is pretty simple, it’s basically our amazing funfetti cupcake recipe. If making this cake for a larger crowd…feel free to just double the recipe. To bake this funfetti sheet cake, first preheat the oven to 350 degrees F. In a medium sized bowl, add the following ingredients: all-purpose flour, cake flour, kosher salt, baking soda, and baking powder. Mix these ingredients well and set aside. Using an electric mixer, beat the unsalted butter and sugar until smooth (roughly 2-4 minutes). Next, add in the one egg and continue to mix until the egg is fully incorporated. Now, rotate between adding the liquids (milk and yogurt) and dry ingredients (flour mixture) until all ingredients are mixed well. Then, fold in the rainbow sprinkles.

After all ingredients are well mixed, fill the cupcake liners half-way. During the baking process the cake mix will expand to fill the entire quarter sheet pan. Bake for 22-30 minutes or until toothpick inserted comes out clean. Then, allow the cupcakes to rest in the muffin pan for a few minutes before moving to a cooling rack. Lastly, decorate and enjoy!

The use of Cake Flour & All-Purpose Flour

With cakes or cupcakes I always like to use a mixture of cake flour and all-purpose flour. It provides the most fluffiness and desired scrumptious taste. Using only all-purpose flour creates a more dense, chewy, and crumb-like texture. Cake flour contains less gluten and protein compared to all-purpose flour. It’s also lighter, softer, finer, and paler in color unlike all-purpose. When using a ratio of both, it provides that good texture needed for a great cupcake.

What kind of sprinkles?

Since we are talking sprinkles, which one should you use? The best sprinkles for baking are either Quin or Jimmie sprinkles. Both are available at your local grocery stores and amazon. Personally, I use this brand Cake Mate sprinkles from amazon.
