- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt

How to Make Lemon Blueberry Sheet Cake
Step 1: Preheat the Oven
Preheat the oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper so there’s an overhang over the two long sides. This will make removing the cake much easier!
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together the dry ingredients: flour through salt. Set aside.
Step 3: Cream Butter and Sugar
In a stand mixer fitted with the paddle attachment (or hand mixer), cream together the sugar and butter until light and fluffy.
Step 4: Add Eggs and Wet Ingredients
Add the eggs, vanilla extract, and buttermilk to the mixture. Mix on low speed until incorporated.
Step 5: Combine Dry Ingredients with Wet Mixture
Gradually add the dry ingredients into the wet mixture. Mix until no streaks of flour remain. Then mix in the lemon juice and zest.
Step 6: Fold in Blueberries
Gently stir in the blueberries with a rubber spatula to avoid breaking them.
Step 7: Bake the Cake
Pour the batter into the prepared baking dish. Bake for about 40-45 minutes or until a toothpick comes out with moist crumbs.
Step 8: Prepare Glaze
Allow to cool completely after removing from oven. For the glaze, combine powdered sugar and lemon juice; pour over cooled cake once hardened.

How to Perfect Lemon Blueberry Sheet Cake
Perfecting your Lemon Blueberry Sheet Cake is simple with these helpful tips. Follow them to ensure you create the best version every time!
- Use Room Temperature Ingredients: Ensure your butter, eggs, and buttermilk are at room temperature for better mixing and texture.
- Don’t Overmix the Batter: Mix just until combined to keep your cake light and fluffy; overmixing can lead to density.
- Fresh Blueberries Only: Opt for fresh blueberries instead of frozen ones, as they prevent excess moisture in the batter.
- Zest Before Juicing: Zest your lemons before juicing them; this maximizes the flavor infused into the cake.
- Cool Completely Before Glazing: Allow your cake to fully cool before adding the glaze to avoid melting and running off.

Common Mistakes to Avoid
Baking can be tricky, and avoiding common mistakes will help you achieve the perfect Lemon Blueberry Sheet Cake.
- Skipping the zest: Forgetting to include lemon zest can lead to a less flavorful cake. Always add the zest for that vibrant lemon flavor.
- Not measuring carefully: Using incorrect measurements, especially for flour, can affect the texture. Use a kitchen scale or the spoon-and-level method for accurate results.
- Overmixing the batter: Mixing too much can lead to a dense cake. Mix until just combined to keep it light and fluffy.
- Ignoring oven temperature: Baking at an incorrect temperature can result in uneven baking. Always preheat your oven and use an oven thermometer if needed.
- Forgetting to toss blueberries in flour: This step helps the blueberries stay suspended in the batter. Don’t skip it; it makes a big difference!
- Rushing cooling time: Cutting into the cake while it’s still warm can make it fall apart. Allow it to cool completely for better slicing.
