This strawberry vanilla cake is a 6-inch layer cake with tons of fresh strawberry flavor. The fluffy vanilla cake layers are super soft and tender. It's topped and filled with strawberry Swiss meringue buttercream, making a perfect light, beautiful dessert.
Preheat the oven to 350°F/180°C. Spray three 6-inch cake pans with nonstick baking spray. Line the pans with 6-inch parchment paper circles. Spray again.

Assembly
Spread a small amount of frosting on the cake board to keep the cake from sliding around.
Place the first cake layer in the middle of the board. Spread ½ cup of frosting on top. Place the second layer on top of the first and repeat.
Place the last layer of cake on top with the bottom facing up. Spread a very thin layer of frosting all over the cake. Freeze for 20 minutes to seal in crumbs.
Spread a thick second layer of frosting all over the cake. Pipe with decorations, garnish with fresh strawberries, and enjoy.
