Funfetti, confetti, whatever you want to call it, white cake dotted with rainbow sprinkles is one of my favorite things on earth. Like, I logically know that sprinkles don’t qualify as a flavor, but that won’t keep me from saying that sprinkles are my favorite flavor. Seriously, add sprinkles to pretty much anything and I’ll love it. Those little pops of color are just so…happy. Is happiness a flavor?I haven’t made many layer cakes in the last year—it’s hard to believe I used to make 10-20 a month!—but that doesn’t mean I haven’t fed my craving for rainbow sprinkles. Last summer’s Funfetti Cookie Cupcakes are one of my favorite recipes in a long time, as is this Funfetti Bundt Cake.Like the traditional layer cake, this is a moist sour cream white cake positively loaded with rainbow sprinkles. Unlike the traditional cake, this batter takes exactly four minutes to mix; just dump everything in a bowl and let your electric mixer have at it until it’s impossibly smooth, thick and voluminous, then stir in 3/4 cup of rainbow sprinkles before baking.

Like most bundt cakes, this one takes its sweet time to bake and cool, but I promise your patience will be rewarded. Once your cake hits room temperature, pour on a glaze, scatter on some more sprinkles and slice it up! Funfetti Bundt Cake would be great for birthdays, picnics, holidays or any old time.I know that restrictions are starting to loosen as vaccines becomes more available, but if you’re not attending gatherings that require a cake of this size, don’t worry, I’m not either. What that means is that I happen to know that this recipe halves well and can be baked in a loaf pan for your immediate pod or just yourself. I don’t know about you, but dipping into my own personal Funfetti cake over the course of a week sounds a lot like happiness to me.

Funfetti Bundt Cake
makes one 10-cup capacity bundt*

Cake:
2 3/4 cups all-purpose flour
2 cups granulated sugar
2 1/2 teaspoons baking powder
1/2 teaspoon Kosher or sea salt
1 cup (2 sticks) unsalted butter, room temperature, cut into 16 pieces
4 large egg whites, room temperature
1 tablespoon pure vanilla extract
1/4 teaspoon pure almond extract or imitation butter extract (optional)
3/4 cup full-fat sour cream, room temperature
1/4 cup whole milk, room temperature
3/4 cup rainbow sprinkles (jimmies, not nonpareils)

Icing & Garnish:
1 1/2 cups confectioner’s sugar
2 tablespoons whole milk
1/2 teaspoon pure vanilla extract
pinch of Kosher or sea salt
rainbow sprinkles (jimmies or nonpareils)

Place an oven rack in the center position. Preheat oven to 325F. Heavily grease a bundt pan with softened butter (or shortening) and dust well with flour. Set aside.

Make the cake. Combine flour, sugar, baking powder, salt, butter, egg whites, vanilla, almond extract, sour cream and milk in a large mixing bowl. Use an electric mixer to mix on low for 30 seconds. Increase speed to medium and mix for 3 minutes. Batter will be thick. Use a silicone spatula or wooden spoon to fold rainbow sprinkles into batter.

Transfer batter to prepared pan and smooth the top with a silicone spatula or wooden spoon. Tap full pan on the counter five times to release any large air bubbles. Bake 65-75 minutes, or until a toothpick inserted in several places comes out clean.

Let cake cool in the pan for 15 minutes. Run a thin, flexible knife around all exposed edges. Invert cake onto a cooling rack and let cake cool completely. Cake may be made up to a day in advance; it will keep double-wrapped in plastic wrap.

Make the icing. In a small bowl, use a fork to whisk together confectioners sugar, milk, vanilla and salt. Mixture should be very thick, but pourable. If it’s too thick, add more milk by the teaspoon up to 3 teaspoons (1 tablespoon); if it’s too thin, add more confectioners sugar in 2 tablespoon increments. Pour over cake. Scatter rainbow sprinkles on immediately. Let sit for 20 minutes to set. Move cake to a serving plate before slicing and serving.

Leftover cake will keep covered at room temperature for up to two days or in the refrigerator for up to five.

Note:

This recipe may be halved and baked in a parchment-lined 9×5-inch loaf pan. Start checking the cake for doneness at the 55 minute mark.
