Homemade Funfetti Cake Ingredients

  • unsalted butter: adds flavor and tender texture
  • granulated sugar: adds sweetness and flavor
  • egg whites: binds the cake together by providing structure – using only egg whites keeps the cake more white in color
  • vanilla extract: adds that classic vanilla flavor to the cake
  • sour cream: adds moisture & fat, activates the baking soda
  • milk: adds moisture
  • all purpose flour: flour is necessary to build structure
  • baking soda: helps to leaven and lift the batter
  • salt: just a pinch to balance the sweetness
  • jimmie sprinkles: sprinkles are critical in homemade funfetti cake

What Sprinkles to Use for Funfetti Cake

Jimmie sprinkles are the best type of sprinkle to use when making 9 x 13 inch funfetti cake. Jimmie sprinkles are the long, skinny “hot dog” shape sprinkle.

I do not recommend using nonpareils, the small round ball sprinkles, because their color tends to bleed during baking.

After much searching, I found that Walmart’s Great Value brand jimmie sprinkles are the best looking sprinkles because the colors are bright and the sprinkle mixture doesn’t contain brown sprinkles. I don’t want brown sprinkles because they don’t look appealing!

Tips

  • Properly measure the all purpose flour using the spoon and sweep method.
  • Use room temperature butter for easier creaming of the butter and sugar.
  • Use jimmie sprinkles
  • Combine the dry ingredients into the wet ingredients just until they are combined. Over mixing could lead to dry, dense cake.

  1. Box mixes are the best! To me, they are so reminiscent of childhood- especially flavors like yellow butter cake and funfetti. I also totally love any and all boxed mix brownies :)

    1. It’s up to you! If you want to remove it, I would suggest lining the pan with foil before baking.

  2. This does not work well if you bake all of the batter in one pan. The cake does not bake all the way through in the time alloted. It works better to split equally into 2 9×13″ pans.

    1. Hi Sara! Every oven is different – but the batter fits in one 9×13 inch pan.

    2. It fits in a 9x 13 pan, but it takes longer to bake through than you specify here. It took about 10 minutes longer in my oven.

      I baked this recipe 12 times for a big event. It works better if you split the batter into 2 9×13 pans, bake for the time specified here, then frost as a 2-layer cake.

    3. I wish I read this earlier! I’m baking this cake now and it’s been in the oven 20 minutes longer than anticipated. The middle is still so moist and not cooking through! I have a brand new oven too, so I think next time I’ll split it up. 

    4. Gahhh, I wish I’d read this comment first. Just wasted an entire batch, the middle most definitey did not cook through. End result, burnt edges, soggy middle and a cake in the trash. *Sigh*. It does have great flavor though so Im trying again with this advice.
