Expert Tips for Grandma’s Lemon Custard Cake
-
Use Fresh Lemons: For the best flavor, always opt for fresh lemons instead of bottled juice. Fresh zest enhances the cake’s brightness.
-
Chill the Dough: Allowing the crust dough to chill for at least 20-30 minutes helps achieve a tender and flaky crust. Don’t skip this step!

Strain the Custard: To ensure a silky-smooth texture, strain the custard before pouring it into the crust. This removes any lumps for a perfect finish.
-
Watch the Baking Time: Keep an eye on the cake as it bakes; it should be set but still slightly jiggly in the center. Overbaking can lead to a dry custard.
-
Cool Completely: Let the cake cool before slicing for cleaner cuts and a firmer texture. This allows the custard to set properly, making each slice a delight.

What if my custard doesn’t thicken properly?
Should your custard turn out too thin, don’t worry! Make a slurry by mixing a tablespoon of cornstarch with 1-2 tablespoons of cold milk, then gradually whisk this into the custard while it cooks over medium heat. Continue stirring until it thickens. If you happen to strain the custard before baking, that can also help get rid of any lumps!
Can I make Grandma’s Lemon Custard Cake dairy-free or vegan?
Very! To make this dessert vegan, you can replace the egg yolks with 2 tablespoons of cornstarch or a 1/4 cup of silken tofu blended until smooth. Also, substitute whole milk with almond, coconut, or soy milk, and use vegan butter for the crust—you’re all set for a delicious plant-based version.
How long should I let the cake cool before slicing?
It’s best to let the cake cool completely, ideally at least 2 hours, before slicing. This ensures the custard fully sets and provides a firmer texture, enabling you to create clean, beautiful slices. Patience pays off here!
