Instructions
Step 1: Make the Cake
- Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans or line them with parchment paper.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
- In a large bowl, beat butter and sugar until light and fluffy (about 3-4 minutes). Add eggs one at a time, mixing well after each addition.
- Stir in vanilla extract, lemon extract, and lemon zest.
- Gradually alternate adding the dry ingredients and buttermilk to the wet mixture, starting and ending with the dry ingredients. Mix until just combined. Stir in the lemon juice.
- Divide the batter evenly among the prepared pans. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
- Cool the cakes in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Step 2: Prepare the Lemon Cream Filling
- In a mixing bowl, whip heavy cream to soft peaks and set aside.
- In another bowl, beat cream cheese, powdered sugar, lemon juice, and lemon zest until smooth.
- Gently fold the whipped cream into the cream cheese mixture. Chill until ready to use.
Step 3: Make the Lemon Buttercream Frosting
- Beat butter until smooth and creamy. Gradually add powdered sugar, mixing on low speed.
- Add lemon juice, heavy cream, lemon zest, and salt. Beat until light and fluffy. Adjust the consistency with more cream if needed.
Step 4: Assemble the Cake
- Place one cake layer on a serving plate. Spread a generous layer of lemon cream filling over the top. Repeat with the second layer.
- Top with the final cake layer and frost the outside of the cake with lemon buttercream frosting.
- Decorate with lemon slices, zest, or white chocolate shavings as desired.
Step 5: Chill and Serve
- Chill the cake for at least 30 minutes before serving for clean slices.
- Store leftovers in the refrigerator for up to 3 days.
