For the Cake
For the Frosting
Preparation
- Step 1
Make the cake: Heat oven to 325 degrees and place a rack in the center. Butter and line the bottoms of two 8-inch round cake pans with parchment paper. Butter the parchment. Flour the pans, coating the bottom and sides, then tap out any excess flour.
- Step 2
In a medium bowl, whisk together flour, baking powder, baking soda and salt. In a small bowl, stir together milk and vanilla.
- Step 3
In a mixer fitted with the paddle attachment, beat butter and sugar at medium-high speed until light and fluffy, 2 to 3 minutes. Reduce speed to low and, with mixer running, slowly add egg and whites and beat until smooth and creamy, 1 to 2 minutes. Scrape down bowl. Add half the flour mixture, then the milk mixture, then the remaining flour mixture, beating to blend after each addition. Scrape down bowl and blend once more. Remove bowl and use a spatula or spoon to mix in sprinkles by hand.
- Step 4
Divide batter evenly between the pans and bake until the tops are just dry to the touch and a toothpick inserted into the center comes out clean, 20 to 25 minutes. Rotate the pans halfway through baking.
- Step 5
Transfer pans to a wire rack and let cool completely, at least 4 hours, before turning out.
- Step 6
Make the frosting: In a mixer fitted with the paddle attachment, beat cream cheese, butter and salt together at medium speed until light and fluffy, 2 minutes. Reduce speed to low and, with mixer running, slowly add sugar and beat until smooth. Beat in vanilla just until incorporated. Taste frosting; you should be able to taste the cream cheese and a little bit of saltiness, as well as the sweetness. If desired, add more salt or sugar. Keep refrigerated.
- Step 7
Turn cooled cakes out of pans. Using a bread knife, cut off any domed or uneven parts of each cake to make flat surfaces. Place one of the cakes on a platter or a cake stand, cut side up. Using an offset spatula, frost the top. Stack the other layer on top, cut side down. Place remaining frosting on top of the cake and, working from the center outward, frost the top and sides of the cake.
- Step 8
Place a baking sheet under the platter or cake stand, to catch any fallen sprinkles. Sprinkle the top with a layer of sprinkles. Toss remaining sprinkles at the sides of the cake, or press handfuls of sprinkles gently up the sides to make a thicker coating. Gather fallen sprinkles and repeat until coated to your liking.
- Step 9
Refrigerate cake 30 minutes or longer to set. Serve cool.
- Julia's house blend: 2 parts blue, 1 part yellow, 1 part orange, 1 part bright pink. It's best not to use white, light pastel or "natural" sprinkles. They just disappear (poof!) into the cake after baking.

Comments
Rather than cutting off the domed top of a cake, you can completely eliminate the dome by doing this: Cut a terry cloth towel into strips and saturate in water. Wrap the strips around the cake pan. Then bake as usual. The cake will come out of the oven as flat as a pancake.
This looks like a great cake, one that I'll definitely make on a snowy afternoon, or snow-bound during a blizzard. But I have two comments: the photo looks like it's a 3 layer cake but you only call for two. And your gram measures for the flour--and sugar-- are very inconsistent in many of your recipes from different authors. 1 cup of flour is either 120 or 125 grams of flour, depending on who you consult (King Arthur says 120)
I've baked three of these cakes for family gatherings, and the consistent success of the results has put this particular recipe at the top of my "go to" list for celebratory events requiring something colorful, delicious, and appealing to those with the wispiest threads of childhood still left in them. I follow the recipe's directions exactly, except that I double all the listed ingredients, including the frosting, ending up with three 8-inch layers. Highly recommended!
I wanted to love this recipe, but there were so many issues along the way. Batter split, frosting split, cake was so thin. Would recommend trying another if you’re an amateur. Spent an extra two hours trying to problem solve and restarting
Was looking for a good funfetti recipe I could make last minute. This one seemed way easier than others I found(only 2 eggs to separate! No random ingredients) and had a faster baking time. I followed the cake recipe exactly. Yes, this recipe results in a more petite cake than veteran cake bakers may expect from a 2 layer cake, but I didn’t need a towering cake for this occasion and yummy cake is yummy cake. I converted the cream cheese recipe to a strawberry cream cheese recipe by adding ~1c pulverized freeze dried strawberries with the confectioner’s sugar. I reduced confectioners sugar to 2.5c. Cake was moist and had a loose crumb. Crowd approved!!
Love this cake recipe! It’s my go to for birthdays. I prefer a less sweet frosting though, and 2 cups of powdered sugar is perfect! Another tip: test your sprinkles before dumping them in the batter. We’ve had a few fails, but cake still tastes great!
@Meredith what do you mean test your sprinkles? And what did you go with?
