Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch cake pans or line them with parchment paper.

Step 2: Mix Dry Ingredients

In a medium bowl, sift together the cake flour, baking soda, baking powder, and salt. Set aside.

Step 3: Cream Butter and Sugar

In a large mixing bowl, beat the butter and sugar on medium-high speed for about 3-4 minutes, until light and fluffy.

Step 4: Add Eggs and Flavorings

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract, lemon extract, lemon juice, and lemon zest.

Step 5: Alternate Wet and Dry Ingredients

Reduce the mixer speed to low. Add one-third of the dry ingredients, followed by half of the buttermilk. Repeat this process until all ingredients are combined, beginning and ending with the dry mixture. If using, mix in the yellow food coloring to achieve a vibrant lemon hue.

Step 6: Bake

Divide the batter evenly between the prepared cake pans. Smooth the tops and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: Cool the Cakes

Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely before frosting.

Step 8: Prepare the Frosting

In a mixing bowl, beat the cream cheese and butter together until smooth. Gradually add the powdered sugar, mixing on low speed. Add the lemon juice, lemon zest, and vanilla extract, then beat until fluffy.

Step 9: Assemble the Cake

Place one cake layer on a serving plate. Spread a generous amount of frosting on top. Add the second layer and frost the top and sides evenly.

Step 10: Decorate and Serve

Decorate with lemon slices, zest, or piped frosting for a beautiful finish. Chill for at least 30 minutes before slicing.
