  • 4 large eggs, at room temperature
  • 3/4 cup granulated sugar
  • 1/2 cup (1 stick) salted butter, melted
  • 1 teaspoon vanilla extract
  • 3/4 cup all-purpose flour
  • 2 cups lukewarm whole milk
  • 1/2 teaspoon cream of tartar
  • 3 tablespoons rainbow sprinkles, plus 2 tablespoons for garnish
  • 1 recipe Vanilla Icing (page 92)
  • 1 tablespoon white sparkling sugar, for garnish (optional)
  • 1/2 teaspoon edible glitter, for garnish (optional)
  • Cake sparklers or sparkler candles

Preheat oven to 325°F. Coat an 8-inch springform pan with baking spray or line an 8-inch round cake pan with aluminum foil, allowing 2 inches of overhang around the sides, and coat with baking spray.

Separate the eggs; place the egg yolks in a mixing bowl with the sugar and beat on high speed with an electric mixer for 2 minutes, or until lemon colored. On low speed, gradually add the melted butter and vanilla, scraping down sides as needed. Add the flour and mix just until flour is combined. Gradually add the milk, beating just until flour is combined.

If using the same mixer and beaters to beat the egg whites, wash the beaters thoroughly; place the egg whites in a separate mixing bowl. Beat on medium speed until foamy; add cream of tartar. Increase the speed to high and beat until the egg whites form stiff peaks, about 2 minutes. Gently whisk about one-third of the egg whites into the thin batter; gently fold in the remaining egg whites and 3 tablespoons of sprinkles with a silicone spatula. (The pan will be almost full.) Bake for 40 minutes, or until the center jiggles slightly when gently shaken.

Let cool completely on a wire rack, about 1 hour. Cover and refrigerate at least 2 hours to chill. If using a springform pan, remove sides and bottom of pan; otherwise, remove the cake from the pan using aluminum foil as handles. Remove foil and transfer the cake to a serving plate. Spread Vanilla Icing over the cake, allowing icing to drip over the edges. Sprinkle remaining 2 tablespoons of sprinkles, the sparkling sugar, and edible glitter over the cake, and place cake sparklers or candles in the center of the cake.

Note: Cake sparklers are not the same as fireworks sparklers. They do not contain magnesium, chlorates, or perchlorates and can easily be found online.
