How To Make A German Lemon Cake with a Lemon Glaze
For more detailed, step-by-step instructions check the recipe card below.
Preparing The Batter
- Cream butter and sugar very creamy in a large bowl.
- Add the zest of 3 lemons and the juice of 1 lemon to the batter. Slowly add the eggs one at a time.
- Add the flour, baking powder, and salt. Continue until the dry ingredients are well incorporated into the batter.
- Spread batter onto the parchment-paper covered baking sheet.
- Bake for 20 minutes at 350° Fahrenheit.
- Remove the baked cake from the oven. Use a wooden toothpick and insert it into the center to check for doneness.
- Poke small holes into the cake. This allows some of the glaze to penetrate the cake, and make it moist and extra lemony.
Preparing The Glaze
- Whisk lemon juice and powdered sugar until creamy.
- Spoon the mixture onto the cake.
- Use a knife or an icing spatula to spread the glaze evenly across the entire sheet cake. Allow the icing to harden before serving.
PRO TIP: If you don't have powdered sugar on hand you can easily make it yourself. Combine 1 cup of granulated sugar and add one teaspoon of cornstarch in a small food processor and blend until the sugar turns to a powder consistency.
Tips for Success
- Always use fresh lemons - always. Avoid substituting the fresh lemons with lemon extract or bottled lemon juice. It's just not the same.
- For a fun twist, try Meyer lemons.
- Be sure to use unsalted butter. Different brands use different amounts of salt in their salted butter. Therefore using salted butter makes it more difficult to control the salt content. Instead, use unsweetened butter - this way you'll know exactly how much salt has been added.
- Poking holes into the baked cake allows the glaze to seep through the cake. This makes the cake extra moist and lemony.
- Storing the cake in the fridge tends to make it stiff and lose some of its flavors. Instead, cover the baked cake and store for 2-3 days at room temperature.
- If the glaze is too runny, add more powdered sugar.
Tips for Keeping and Storing The Lemon Sponge Sheet Cake?
- If you're making Lemon Sponge Cake without the glaze, it will easily keep fresh for 3-4 days.
- Adding the lemon glaze seals the top of the cake and will keep it moist and fresh for about one week
- Lemon Sponge Cake freezes very well. So long as you don't glaze the cake beforehand.
Reheating the Cake
Preheat your oven to 200° Fahrenheit. Remove the Lemon Sponge Cake from the freezer and place it on a baking sheet. Allow the oven to warm the cake for 10 minutes.
Turn the oven off and allow the cake to sit in the oven for an additional 10 minutes.
