Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a large bowl, whisk together flour, sugar, baking powder, and salt.
In a separate bowl, whisk together eggs, milk, vegetable oil, lemon juice, and lemon zest.
Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix.
Divide the batter evenly between the prepared cake pans.
Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
While the cakes are cooling, prepare the lemon cream filling. In a medium bowl, beat the softened cream cheese until smooth.
Add powdered sugar and beat until well combined. Gradually add heavy cream, lemon juice, and lemon zest, beating until light and fluffy.
Once the cakes are completely cool, spread the lemon cream filling evenly over one cake layer. Top with the second cake layer.
Chill the cake for at least 30 minutes before slicing and serving.
Notes
For a stronger lemon flavor, you can add a tablespoon of limoncello to the cream filling. Garnish with fresh lemon slices or a dusting of powdered sugar.
