FAQs
Can I use bottled lemon juice instead of fresh?
Fresh lemon juice is recommended for the best flavor, but bottled lemon juice can work in a pinch.
Can I make this cake in advance?
Yes, you can bake it a day ahead and store it at room temperature or in the fridge. Glaze it before serving for the freshest look.
Can I use lemon extract instead of zest?
Lemon extract can be used, but fresh zest provides a more vibrant, natural lemon flavor.
How do I prevent the cake from being dry?
Use full-fat dairy (like buttermilk or sour cream) and don’t overbake. The mashed texture from the lemon juice also helps retain moisture.
What’s the best pan for a sheet cake?
A 9×13-inch rectangular pan is standard. Metal pans bake more evenly than glass or ceramic.
Can I frost the cake instead of glazing it?
Absolutely! Cream cheese or buttercream frostings pair beautifully with lemon.
How should I store leftovers?
Wrap tightly or place in an airtight container and store at room temperature or in the fridge.
Can I add fruit to the batter?
Yes! Blueberries or raspberries make great additions—just toss them in a little flour before mixing into the batter.
Can this cake be made gluten-free?
Yes, a 1:1 gluten-free flour blend works well in this recipe.
Is this cake good for birthdays or parties?
Definitely! It’s simple to serve and has a universally loved citrusy flavor that suits all occasions.
