Instructions:
- Preheat oven to 350°F (175°C). Grease and flour the springform pan. Line the bottom with parchment paper for extra insurance.
- Whisk together flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
- In a large bowl, cream together butter and sugar until light and fluffy using an electric mixer.
- Beat in eggs one at a time, then stir in vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the milk and Limoncello, beginning and ending with the dry ingredients. Mix until just combined – don't overmix!
- Stir in the lemon zest.
- Pour batter into the prepared pan and bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
- In a large bowl, beat the cold mascarpone cheese and softened butter together until smooth and creamy.
- Gradually beat in the sifted powdered sugar until fully incorporated. Stir in the Limoncello and vanilla extract.
- Once the cake is completely cool, frost the top with the Mascarpone frosting.
- Garnish with lemon slices, zest, and fresh mint leaves, if desired. Dust with powdered sugar.
- Chill the frosted cake for at least 15 minutes before serving to allow the frosting to set.
