Nothing screams Happy Birthday!quite likea big and fluffyvanilla cake LOADED with rainbow sprinkles! Really, what more could a girl ask for? (Other than a lock of John Stamos’s hair.)

So as a little birthday gift to myself, I decided to take a walk down memory lane by revampingan old childhood favorite. Not only would it be made from scratch, but it would be toweringand sprinklelicious!

Ever since I was livin’ it up as a 90’s kid, I’ve been obsessed with Funfetti. I mean, how could you NOTbe totallyfascinated by a cake brimming with colorful sprinkles and slathered in the best vanilla frosting in the world–rainbow chip. Yes, that undeniably lusciousvanilla frosting loaded with itty bitty rainbow chips! I could eat that stuff by the ladleful.

This cake turned out just as heavenly as I remember it. With itsluminously white hue speckled with those captivating flecks of rainbow, it’s impossible not to fall back into childhood.

If you’re wondering how I got this cake so blindingly white, I did a few things. First off, I used only whites–no yolks. Yolksplay a big part in giving vanilla cakes that yellow tinge. Secondly, I usedhalfbutter and half shortening. (Warning: baking nerdalert!)Not only does shortening lend to the whiteness of this cake, butwhen creamed with sugar, air molecules are trapped, which not only gives the cake more lift, but also createsa more tender, light, and airy texture. Speaking of light and tender,I also used cake flour instead of all-purpose. Why? Cake flour has a lower protein content than all-purpose flour, which means less gluten, AKA toughness.

Another ingredient that aids in white cakes is clear imitation vanilla. While “imitation” might be considered a dirty word in the baking world, hear me out on this one.As opposed to pure vanilla, clear vanilla does not affect the color of anything you add it to. Obviously. Furthermore, it’s one of the secrets to creating that nostalgic cake batter/birthday cake sweetness reminiscent of Funfetti cake mix. And with the addition ofa little almond extract, you’ve got the best-tasting vanilla cake in the entire universe!

In order to Funfetti-tize this cake, sprinkles are absolutely mandatory. Rainbow jimmies are the sprinkle of choice since their color doesn’t bleed into the cake batter like the little tiny nonpareil (balls) do. Also, their larger size creates those alluringlyvibrant pockets of color throughout the cake.

Asan homage to my favorite rainbow chip frosting, I decided to incorporate it into this cake.Enter: rainbow chip cheesecake mousse.

This stuffis basically everything good wrapped up into one amazingly fluffy, lusciously addictive filling. First you take a tub of rainbow chip frosting, whip it up with a box of cream cheese,then fold in some whipped topping. That’s it! It’s so simple, yet so divine. I couldn’t think of a more perfect filling to go between each fluffy funfetti layer.

Finally,a Funfetti cake wouldn’t be TRUELY Funfetti without its white vanilla buttercream exterior. This frosting is a basic American buttercream, but with more heavy cream. As opposed to ordinary milk, I’ve found that heavy cream creates a smoother, silkier, whipped feel. It also lightens the frosting, adding more volume and making it easier to spread. Clear imitation vanilla along with almond extract make another appearance in this frosting for that lovelycake batter-like flavor that I mentioned earlier.

And being that this IS a birthday cake,bright colors and sprinkles were an absolute must. So, to add some color, I divided the remaining buttercream amongfour bowls and dyed each separately. I used green, blue, red, and purple. To swirl them together, all I did was use a spatula to spoon the frostingsinto separate sections of apiping bag.

Then I piped some stars around the top border of the cake using a Wiltons #2D tip.

Last, but not least, we have the SPRINKLES!!!

If you’ve been a loyal follower of mine long enough, you’ll know that I have a bit of a sprinkle obsession.I’m still unsure if I belong on “My Strange Addiction” or “Hoarders”. Yes, it’s that bad. I suppose there could be worse addictions though…

Sprinkle medleys seem to be all the rage these days, and since I have such a vast array of sprinkles, I decided to make my own little “birthday” medley with a mix of stars, colorful spheres, and nonpareils.

Servings 12 Servings



  • 3 ⅓ cup cake flour
  • 1 Tablespoon baking powder
  • 1 teaspoon salt
  • ½ cup unsalted butter room temperature
  • ½ cup shortening
  • 2 cups granulated sugar
  • 6 large egg whites room temperature
  • 1 Tablespoon clear imitation vanilla
  • ¼ - ½ teaspoon almond extract*
  • 1 ½ cup milk
  • cup rainbow jimmy sprinkles

Rainbow Chip Cheesecake Mousse:

  • 8 ounces cream cheese softened
  • 1 (16 oz) tub Rainbow Chip frosting
  • 1 (8 oz) tub whipped topping

Vanilla Buttercream:

  • 1 ½ cup unsalted butter softened
  • Pinch of salt
  • 5 cups powdered sugar
  • ½ cup heavy cream
  • 2 teaspoons clear imitation vanilla
  • ¼ teaspoon almond extract

For Assembly:

  • Sprinkles for decorating
  • Icing colors I used red, blue, green, and purple


Make the Cake:

  • Preheat oven to 325ºF. Line four** 8-inch round baking pans with parchment paper and spray with nonstick cooking spray.

  • In a medium bowl, whisk together flour, baking powder, and salt; set aside.

  • In the bowl of a stand mixer fitted with the paddle attachment, beat butter and shortening together until smooth. Add sugar and beat on med-high until pale and fluffy, about 2-3 minutes.

  • Reduce speed and add egg whites one at a time,beating wellafter each addition. Addvanilla and almond extract. Mixinhalf of the dry ingredients, followed by half of the milk, followed by the remaining dry ingredients, and finally the remaining milk. Try not to overmix. Gently fold in the sprinkles.

  • Pourbatter evenly among theprepared pans, smoothing the topswith a spatula. Bake 30 - 34 minutes, or until a toothpick inserted into the center comes outwith few moist crumbs attached.Allow cakesto cool for 10 minutes before transferring toawire rack to cool completely.

Make the Mousse:

  • In the bowl of a stand mixer fitted with the paddle attachment, beat the cream cheese until smooth. Add the rainbow chip frosting, beating until combined. Fold in the whipped topping. Refrigerate mousse for about 30 minutes to allow it to firm up a bit before spreading between the layers.

Make the Buttercream:

  • In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and salt on medium speed until creamy, about 2 minutes. Reduce the speed to the lowest setting and gradually add the powdered sugar, beating well after each addition. Add the heavy cream, vanilla and almond extract. Increase to high speed and beat until very light and fluffy, about 3-4 minutes.

To Assemble:

  • Place one cake layer on a cake pedestal or platter, spread about a third of the mousse on top.Repeat with the remaining cake layers and mousse. Using an offset spatula or knife, frost the sides and top of the cake with the buttercream. You'll have some leftover for the star border. Carefully press sprinkles along the bottom 3 inches of the cake, and then on the top.

  • Divide the remaining buttercream among 3 or 4 bowls and dye each separately with desired colors. Using a spoon or spatula, spoon buttercream into sections in a pastry bag that's fitted with a large star tip. (See photo above.) You might need to do a few practice swirls on parchment paper before you get all 3 or 4 colors to come out. Pipe stars around the top border of the cake. Refrigerate cake until ready to serve.


*I added 1/2 teaspoon, which was very flavorful, but if you don't care as much for almond extract, you might want to add just 1/4 teaspoon.

**If you have deep enough pans (4-inch depth),you could bake the batter in just two 8-inch pans, and split the layers with a knife. However, the baking time will be longer. You could also split the batter among two or three 9-inch pans.
