The first step is one of the most important – lining the 9×13 pan with parchment paper! It makes removing the cake so much easier and keeps it looking nice
First, you’ll whip up a super fluffy batter by creaming butter and sugar, then slowly adding egg whites.
You’ll mix your dry ingredients in one bowl and your milk, yogurt, and vanilla in another.
Then it’s just a matter of combining everything. After mixing your batter, gently fold in the sprinkles. This keeps them from bleeding into the batter and turning your cake weird colors.
Then spread the batter into a 9×13 pan.
Bake it, let it cool, and frost with a creamy homemade vanilla buttercream. Don’t forget the extra sprinkles on top!
You could, but using just egg whites keeps the cake light and bright without that extra richness that yolks bring. For that classic funfetti flavor, egg whites work best!
Totally! Yogurt and sour cream are both great — they add moisture and a little tang. Just use what you have on hand.
Stick a toothpick in the center — if it comes out clean or with just a few moist crumbs, you’re good to go!
