Equipment
- 4-inch Round Cake Pans (x2)
- Electric Mixer (Stand or Hand-Held)
Ingredients
Lemon Cake
- ½ cup granulated sugar
- zest of half a large lemon (around 2 teaspoons fresh lemon zest)
- ¼ cup whole milk
- 2 tbsp fresh lemon juice
- 1 large egg
- ¼ cup vegetable oil
- 2 tbsp sour cream
- ¼ tsp vanilla extract
- 1 cup cake flour or all purpose flour, fluffed, spooned and leveled
- ¾ tsp baking powder
- ¼ tsp coarse Kosher salt (if using table salt, use half the amount)
Coconut Buttercream
- 10 tbsp unsalted butter, softened to room temperature
- 1 ¼ cups powdered sugar
- 1 tsp meringue powder (optional)
- small pinch salt
- ½ tsp vanilla extract
- ½ tsp coconut extract
- 1 cup unsweetened "natural" coconut flakes
Instructions
Cake
- Preheat the oven to 350 F, and position a rack in the center of the oven. Lightly spray the insides of two 4-inch round cake pans with non-stick baking spray. If you only have 6 inch pans, you can use those, but your cake layers will be thinner, and will need to bake for a shorter amount of time.
- In a bowl, combine the sugar and lemon zest. Use your fingers to rub the zest into the sugar until fragrant.
- Add the milk, lemon juice, egg, oil, sour cream and vanilla, and whisk until smooth.
- Add the flour, baking powder and salt, and whisk just until combined.
- Divide the batter between the pans. Bake the cakes for about 25-28 minutes, until the tops spring back when gently touched, and a toothpick or cake tester inserted in the center comes out clean or with moist crumbs clinging to it.
- Set the pans on a cooling rack and cool for 15 minutes, then turn the cakes out of the pans. Cool completely before frosting.
Buttercream
- With an electric mixer (stand or hand held), beat the butter for one minute, until smooth.
- With the mixer on low, add the powdered sugar, meringue powder and salt, mixing until combined. Add the extracts. Beat on medium speed for several minutes, until very light and fluffy. If the buttercream seems too stiff, you can add milk, one teaspoon at a time, to get your desired consistency.
- Stack, fill and frost the cakes with the buttercream. Don't worry about making it too smooth or perfect, since it will be covered with coconut.
- Before the frosting crusts over, press the coconut over the top and sides of the cake.
Notes
Store leftover cake in an airtight container at room temperature for up to 2-3 days.
