Common Mistakes to Avoid
Baking the perfect Lemon Blueberry Sheet Cake requires attention to detail. Here are some common mistakes to steer clear of:
- Using cold ingredients: Ensure all ingredients, like eggs and sour cream, are at room temperature for better mixing and texture.

- Not swirling enough: When adding the blueberry mixture, make sure to create a nice marbled effect for balanced flavor in every bite.
- Ignoring baking time: Check your cake a few minutes before the suggested baking time with a toothpick. Overbaking can dry out your cake.
- Skipping the glaze: The lemon glaze adds essential moisture and flavor. Don’t skip this step, as it elevates the overall taste.

- Microwave: Heat individual slices for about 10-15 seconds on medium power. Cover with a damp paper towel to retain moisture.
