Funfetti Layer Cake with Whipped Vanilla Frosting
Moist, fluffy vanilla confetti cake filled and topped with a sweet and creamy vanilla frosting and sprinkles.
Ingredients
For the Cake:
  • 1 cup 240 ml whole milk, at room temperature
  • 4 large egg whites 120 g, at room temperature
  • 1 whole egg at room temperature
  • 2 teaspoons 10 ml pure vanilla extract
  • 1/4 teaspoon 1.25 ml almond extract
  • 2-3/4 cups 315 g cake flour, sifted
  • 1-1/2 cups 300 g sugar
  • 1 tablespoon + 1 teaspoon 19.5 g baking powder
  • 3/4 teaspoon 5 g salt
  • 12 tablespoons 170 g unsalted butter, at room temperature and cut into cubes
  • 1/2 cup Rainbow Jimmies or a few generous handfuls
For the Frosting:
  • 3 sticks + 2 tablespoons 375 g unsalted butter, softened and cut into cubes
  • 3.5 cups 400 g confectioners’ sugar, sifted
  • 3 tablespoons 45 ml milk
  • 1 tablespoon 15 ml pure vanilla extract
  • a pinch of salt
  • rainbow jimmies quins or other any other sprinkles for decorating
Instructions
For the Cake:
  1. Preheat oven to 350°F. Grease, line with parchment, butter and flour two round 8-inch pans.
  2. In a medium bowl or measuring cup, combine and stir the eggs, 1/4 cup of milk, vanilla and the almond extract. Set aside.
  3. In the bowl of an electric mixer fitted with the paddle attachment, combine the dry ingredients, including the sugar, together on low speed (I use the “stir” setting on my mixer) for 30 seconds.
  4. Add the butter and blend on low speed for about 30 seconds, then add remaining 3/4 cup of milk, and mix on low speed until just moistened. Increase to medium speed and mix for 1-1/2 minutes.
  5. Scrape the sides of the bowl and begin to add the egg/milk mixture in 3 separate batches; beat on medium for 20 seconds after each addition. Gently stir in the rainbow jimmies, until just combined.
  6. Divide the batter in two, spreading it evenly with a small offset palette knife. If you have a kitchen scale, weigh the batter in the pans to ensure 2 even layers.
  7. Bake 25-35 minutes or until a cake tester comes clean when inserted into the center. Be so careful to not over-bake. Check cake at 20 minutes, but not before, and once you feel it’s almost ready, set the timer for 2 minute intervals.
  8. Let cool on racks for 10 minutes before loosening the sides with a small metal spatula, and invert onto greased wire racks. Gently turn cakes back up, so the tops are up and cool completely.
For the Frosting:
  1. In the bowl of an electric mixer fitted with the paddle attachment, whip butter for 8 minutes on medium (I use “4″ on my KitchenAid). Butter will become very pale & creamy.
  2. Add remaining ingredients and mix on low speed for 1 minute, then on medium for 6 minutes. Frosting will be very light, creamy and fluffy.
  3. Best used right away (for ideal spreading consistency).
Assembly of the Funfetti Cake
  1. Place a small dollop of frosting in the center of a cake plate or 8-inch round thin cake board, and place the bottom cake layer on top.
  2. Place 1 cup of frosting on top of the cake layer, and spread evenly with a small offset palette knife. Sprinkle a handful of sprinkles (jimmies, quins--anything!) on top of the frosting (optional).
  3. Gently place 2nd cake layer face-down on top. Place a generous scoop of frosting on top, spreading evenly with a small offset palette knife and working your way down the sides until you have a thin layer of frosting over the entire cake. Chill until set, about 30 minutes.
  4. Remove from refrigerator and cover cake with a final layer of frosting. Sprinkle until your heart's content!
