There is something so nostalgic about funfetti cake and also the classic sheet cake. Funfetti cake was my absolute favorite growing up and I would request it for every birthday. Of course, back then, we really only made sheet cakes because they were so easy.

My son is about to turn 5 in just a few weeks and he has requested a sprinkle cake. I figured it would be best to make a healthier version of a Funfetti sheet cake for him to dig into on his big day.

I also considered my super fluffy, yellow birthday cake recipe but ultimately couldn’t resist this cake!

Ingredients in a Homemade Funfetti Cake

  • Unsalted Butter – Use organic, grass-fed butter if possible.
  • Whole Milk – Moistens the batter and adds protein and structure to the cake.
  • Vegetable Oil – Makes it incrediably moist.
  • Vanilla and Almond Exctract – Enhances the flavors in the cake and adds extra flavor.
  • Super Fine Sugar – Something like Baker’s sugar works best.
  • Large Eggs – Eggs work to moisten and stabilize a cake.

What Is A Sheet Cake?

A sheet cake is traditionally baked on a flat rectangular pan like a sheet pan (with sides) or a jelly roll pan. However, we use a 9×13 rectangular cake pan and since it’s a single layer rectangular pan we call it a sheet cake.

These single-layer cakes are almost always frosted, with decorations and ornamental frosting along the borders and the flat top surface.

Use Quality Ingredients

We always use organic, whole ingredients for the most part. For this recipe, we also used all grass-fed dairy products. The reason we used grass-fed milk and butter is that they offer more of a balanced ratio of essential fatty acids.

Grass-fed farms are better for the environment too and the cows roam the hillside, eating only GMO-free plants without being confined to pens. We truly notice a positive difference in the end result. Using high-quality ingredients always makes a big difference.

Funfetti Buttercream Frosting

The buttercream meringue frosting recipe is absolutely amazing with this cake. It’s soft, fluffy and creamy, and not too sweet. It only has 1 cup of organic sugar, 4 egg whites, and grass-fed butter. It’s so soft and creamy and pretty much perfection!

Tips for Making Homemade Funfetti Cake

  • Use organic ingredients, grass-fed when possible. The taste is so much more balanced and rich.
  • When measuring flour for a cake, lightly spoon it over the measuring cup, then swipe the top using the back of a knife.
  • Use room temperature ingredients.
  • When mixing on low, alternate the dry and wet ingredients.
  • Butter the cake pan or sheet pan well.
  • Don’t over mix once the flour is added.
  • Remember, all oven temperatures are different and cooking times vary. You have to know when your cake is done. Check on it and use the toothpick in the center method.

Frequently Asked Questions

Is Funfetti cake just vanilla with sprinkles?

Technically yes, it’s a white vanilla cake batter with colorful sprinkles which add dots of color throughout the cake.

Can you put sprinkles in cake batter?

You can! This is a great way to add fun and color to a white or yellow cake. The sprinkles will melt leaving a beautiful spot of color!

Is Funfetti white or yellow cake?

Funfetti cake is a moist, fluffy white cake with sprinkles. It has a vanilla flavor but it’s made with less egg yolk so the color is white, not yellow.

What are the best sprinkles to use?

The best sprinkles to use in a cake are jimmies. These are long skinny, colorful sprinkles that you can buy at the grocery store. We buy the rainbow blend and they work great.
