Making Italian Grandma’s Lemon Custard Cake is a delightful experience. Follow these simple steps to create this incredible dessert:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
2. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Eggs: Beat in the eggs one at a time, mixing well after each addition until fully incorporated.
4. Combine Dry Ingredients: In another bowl, sift together the all-purpose flour, baking powder, and salt.
5. Mix Wet Ingredients: In a separate bowl, combine the milk, lemon juice, lemon zest, and vanilla extract.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the wet ingredients. Mix until just combined and smooth.
7. Bake: Pour the batter into the prepared cake pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Allow the cake to cool in the pan for about 20 minutes before transferring it to a wire rack to cool completely.
9. Add Custard: Once the cake is completely cool, slice it in half horizontally. Spread the lemon custard generously between the layers and on top of the cake.
10. Finish with Powdered Sugar: Dust the top with powdered sugar just before serving for an elegant touch.

Following these steps will ensure that your Italian Grandma’s Lemon Custard Cake is a resounding success!
