3-Layer Carrot Cake with Lemon Buttercream Frosting Recipe

  • 1 tablespoon butter, softened
  • Cake:
  • 1 pound cooked carrots, cut into 1/2-inch pieces
  • 3 cups all-purpose flour
  • 2 1/2 cups white sugar
  • 1 1/2 cups coarsely chopped walnuts
  • 1 (8 ounce) can unsweetened pineapple, drained
  • 1 cup corn oil
  • 4 eggs
  • 1 tablespoon ground cinnamon
  • 1 tablespoon baking soda
  • 1 tablespoon vanilla extract
  • 1 teaspoon salt
  • Lemon Buttercream:
  • 1 pound cream cheese, at room temperature
  • 1 1/4 cups butter, at room temperature
  • 1 tablespoon lemon juice
  • 2 teaspoons vanilla extract
  • 5 2/3 cups confectioners' sugar
  1. Preheat oven to 350 degrees F (175 degrees C). Butter three 9-inch round cake pans. Line bottoms with wax paper; grease wax paper with butter.
  2. Combine cooked carrots, flour, white sugar, walnuts, pineapple, corn oil, eggs, cinnamon, baking soda, 1 tablespoon vanilla extract, and salt in a large bowl.
  3. Pour carrot mixture into a food processor, and blend, working in batches if necessary, until smooth. Divide batter among prepared cake pans.
  4. Bake cakes in the preheated oven until a toothpick inserted into the centers comes out clean, about 35 minutes. Cool in the pans for 5 minutes before inverting onto wire racks to cool completely, about 1 hour.
  5. Beat cream cheese, 1 1/4 cup butter, lemon juice, and 2 teaspoons vanilla extract together in a large bowl until smooth. Gradually beat in confectioners' sugar until frosting is smooth.
  6. Place 1 cake layer on a serving plate and spread with 1/4 of the frosting. Place a second cake layer on top of the first; spread 1/4 of the frosting on top. Place third cake layer on top; frost top and sides with remaining 1/2 of the frosting.
