Preheat your oven to 350°F (175°C).

Prepare your cake pans by greasing them with butter and dusting with flour.

Mix together the dry ingredients in a bowl—flour, baking powder, and salt. Whisk until well combined.

Cream the butter and sugar together in a separate bowl until light and fluffy, about 3-5 minutes.

Add eggs one at a time, mixing well after each addition.

Incorporate the Limoncello and lemon zest into the batter, blending until fully mixed.

Combine the dry ingredients with the wet mixture gradually, alternating with milk. Stir gently until just combined.

Pour the batter into your prepared cake pans evenly. Smooth out the tops with a spatula.

Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.

Cool the cakes in their pans for 10 minutes before transferring them to wire racks.
