# How-To Steps:

01 - Preheat oven to 350°F. Grease and line two 9-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
03 - In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, about 3-4 minutes.
04 - Add eggs, one at a time, mixing well after each addition. Mix in lemon zest, lemon juice, and vanilla extract.
05 - On low speed, alternate adding flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly between prepared pans. Smooth the tops with a spatula. Bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.
08 - Beat butter and cream cheese together until creamy and smooth. Add powdered sugar, lemon juice, lemon zest, vanilla, and salt. Beat until fluffy and well combined.
09 - Place one cake layer on a serving plate. Spread with frosting. Top with the second layer and frost the top and sides. Decorate with lemon slices, edible flowers, or sprinkles as desired.
10 - Chill cake for 30 minutes before slicing for cleaner cuts. Serve at room temperature.

# Expert Suggestions:

01 -
  • The combination of tangy lemon and creamy frosting hits that perfect sweet-tart balance that keeps people coming back for seconds
  • Its lighter than chocolate cake but still feels special and celebratory for important moments
  • The recipe is surprisingly forgiving, I learned this after my first attempt where I overmixed everything
02 -
  • Room temperature ingredients actually matter, cold butter won't cream properly and cold eggs can make the batter separate
  • Chilling the frosted cake for 30 minutes makes slicing so much cleaner and prevents the frosting from smearing everywhere
  • Brushing the cooled cake layers with simple lemon syrup before frosting adds moisture and extra lemon flavor
03 -
  • Zest your lemons before cutting them for juicing, it's so much harder to zest a lemon that's already been squeezed
  • Bring your eggs to room temperature in about 5 minutes by placing them in a bowl of warm water
  • Rotating the cake pans halfway through baking helps them bake evenly if your oven has hot spots
