Step‑by‑Step Instructions for Italian Grandma’s Lemon Custard Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab an 8-inch round cake pan and generously grease it with butter or a non-stick spray to ensure your Italian Grandma’s Lemon Custard Cake releases easily after baking. This preparation sets the stage for a perfect bake!
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour and granulated sugar until well combined. This step usually takes about 1 to 2 minutes and creates a light, airy mixture. Setting these dry ingredients aside will help you seamlessly integrate them later into the wet mixture for a smooth batter.
Step 3: Whisk the Wet Ingredients
In another bowl, vigorously whisk together the eggs, milk, melted butter, lemon juice, and pure vanilla extract for about 2 minutes, or until the mixture becomes frothy and slightly pale. This blending activates the custard-like essence of your Italian Grandma’s Lemon Custard Cake and adds that delightful flavor we all crave.
Step 4: Combine Wet and Dry Ingredients
Gradually pour the frothy egg mixture into the bowl containing the dry ingredients. Stir gently and deliberately until just combined, being careful not to overmix—small lumps are perfectly acceptable here! This gentle incorporation enhances the cake’s delightful, custardy texture, setting up the perfect foundation for baking.
Step 5: Bake the Cake
Pour the combined batter into your prepared cake pan, spreading it evenly. Place it in the preheated oven and bake for 30 to 35 minutes. Keep an eye on it; you’ll know the Italian Grandma’s Lemon Custard Cake is done when it’s golden brown and a toothpick inserted in the center comes out clean, with only a few moist crumbs attached.
Step 6: Cool and Serve
Once baked, carefully remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, gently transfer it to a wire rack to cool completely. Once cooled, dust the top with powdered sugar before serving to add a sweet finishing touch and a lovely aesthetic to your Italian Grandma’s Lemon Custard Cake!

Make Ahead Options
Italian Grandma’s Lemon Custard Cake is perfect for those who appreciate a little meal prep magic! You can prepare the cake batter up to 24 hours in advance by combining the dry and wet ingredients separately, then refrigerating each mixture. This not only saves time but also helps the flavors meld beautifully. When you’re ready to bake, simply combine the mixtures gently and pour into the prepared pan. After baking, the cake can be stored in the refrigerator for up to 3 days; just remember to cover it to maintain its moisture. Dust with powdered sugar right before serving for that fresh, delightful finish. With these tips, your Italian Grandma’s Lemon Custard Cake will be just as delicious and help you conquer your busy weeknights!
