Quick Overview
Making Italian Grandma’s Lemon Custard Cake is not only easy but also incredibly satisfying! You’ll find the flavors combine perfectly, building a harmonious blend of lemon and cream.

Key Ingredients for Italian Grandma’s Lemon Custard Cake
Here’s what you’ll need for this delightful dish:
- 1 cup all-purpose flour
- 1 cup sugar
- ½ cup unsalted butter, softened
- 2 large eggs
- 1 cup whole milk
- Zest of 2 large lemons
- ½ cup fresh lemon juice
- 1 teaspoon baking powder
- ½ teaspoon salt
- Optional: Powdered sugar for dusting
Preparation Notes:
- Make sure to soften the butter well before mixing to achieve a smooth blend.
- For fresh lemon juice, it’s best to use real lemons, as bottled juice can lack freshness.
Step-by-Step Instructions
- Preheat the Oven: First, preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan to prevent the cake from sticking.
- Mix the Wet Ingredients: In a large mixing bowl, cream together the softened butter and sugar until fluffy. This will take about 2-3 minutes. Next, add in the eggs one at a time, mixing well after each addition.
- Incorporate the Flavors: Stir in the lemon zest and lemon juice. The mixture will begin to bubble slightly from the acidity of the lemon, which is what you want!
- Combine Dry Ingredients: In a separate bowl, mix the flour, baking powder, and salt. Gradually add this dry combination to the wet mixture, alternating with the milk. Blend until just combined; overmixing can result in a denser texture.
- Bake: Pour the batter into your prepared cake pan and smooth the top. Bake in your preheated oven for approximately 40-50 minutes, or until a toothpick inserted comes out clean.
- Cool and Serve: Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack. Feel free to dust with powdered sugar before serving to add that extra touch of sweetness.
Top Tips for Perfecting Italian Grandma’s Lemon Custard Cake
- Substitutions: If you need a dairy-free option, substituting milk with almond or soy milk can work beautifully without sacrificing flavor.
- Timing: For best results, let the cake cool completely before cutting into it, allowing the custard to set properly inside.
- Common Mistakes: Overmixing the batter can lead to a denser cake, so mix just until combined. The fluffy texture is what makes this cake shine!
Storing and Reheating Tips
Store any leftover Italian Grandma’s Lemon Custard Cake in an airtight container in the refrigerator for up to 4 days. For longer storage, consider freezing the cake—just wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn.
When you’re ready to enjoy it again, let the cake thaw in the refrigerator overnight for the best results, and simply leave it out at room temperature to regain its texture before serving. With these tips, your dessert will taste just as fresh as the first time you made it!
So there you have it, a recipe that effortlessly combines tradition and taste! Don’t be surprised if this becomes your go-to dessert for family gatherings. Happy baking, and enjoy your delicious masterpiece!
