ORANGE ALMOND CAKE WITH SWISS MERINGUE BUTTERCREAM

Steps:

• Preheat oven to 350 degrees. Butter two 8-inch round cake pans and line with parchment paper. Butter parchment and flour cake pans; set aside.
• In the bowl of an electric mixer fitted with the whisk attachment, beat together 1 cup of sugar and egg yolks until light and fluffy. Add orange zest, juice, and almond extract; mix until well combined. Turn mixer off. Remove the whisk and add the paddle attachment. With the mixer on medium, slowly add ground almonds, followed by flour; mix cake batter until well combined.
• In a large bowl, whisk egg whites until soft peaks form. Add salt and remaining 3 tablespoons sugar; beat until stiff but not dry. Set aside.
• Fold melted butter into cake batter, a little at a time. Gently fold in egg white mixture, taking care not to deflate whites. Divide batter evenly between prepared cake pans. Transfer to oven and bake until a cake tester inserted in the center of each cake comes out clean, about 35 minutes. Transfer cake layers to a wire rack to cool completely.
• Invert cakes to remove from pan and remove parchment paper; reinvert cakes. Using a serrated knife, trim tops of cakes to make level. Place four strips of parchment paper around perimeter of a serving plate or lazy Susan. Place the first layer on the cake plate. Spread frosting over the first layer with a small offset spatula so it extends just beyond edges.
• Place the remaining layer on top, bottom-side up. Gently sweep away any loose crumbs with a pastry brush. Using an offset spatula, cover the top and sides with a thin layer of frosting (also use any of the excess frosting visible between the layers). Refrigerate until set, about 30 minutes.
• Using an offset spatula, cover cake again with remaining frosting.
