Funfetti Sheet Cake

When researching funfetti cake recipes – I found a lot that required fancier ingredients. But I wanted to make a funfetti cake recipe that wouldn’t be much more complicated than using a box mix, but way more delicious. And that’s exactly what we’re making today.

How to Make Funfetti Cake

  1. In a large bowl sift together the flour, baking powder, baking soda, and salt.
  2. Then in a separate large bowl, beat together the butter and sugar until fluffy. This step is important for getting a fluffy cake crumb.
  3. Mix in the vanilla and the eggs one at a time. It’s important that your eggs are room temperature here because it helps everything mix together evenly. To do this quickly, place the eggs in a bowl of warm water for 10 minutes before using them.
  4. Then beat in the sour cream, followed by about 1/2 of the flour mixture.
  5. Then mix in the milk followed by the rest of the flour.
  6. Last but not least – gently fold in the sprinkles. Use a large rubber spatula here to avoid the color bleeding.
  7. Then bake the cake for about 25-30 minutes, or until an inserted toothpick comes out clean.

For this recipe, I definitely recommend using jimmies for your sprinkles – these are the long cylindrical ones. I don’t recommend using nonpareils (the little, tiny round ones) in the cake batter because I find they bleed color a lot more than jimmies. Obviously for decorating your cake – feel free to use whichever you prefer.

Then I frosted my cake with vanilla buttercream. It’s fluffy, it’s creamy, and it’s completely delicious. It’s made with butter, powdered sugar, a little salt, and heavy cream (or milk if that’s all you have on hand). If you like your frosting bright white, you can substitute 1/4 cup of the butter with 1/4 cup of shortening.
