- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt
Wet Ingredients
- 1 cup butter (2 sticks), softened
- 1 1/2 cups granulated sugar
- Juice and zest of 2 lemons (about 1/4 cup lemon juice)

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 of the pan. This will make removing the cake much easier!
Step 2: Prepare the Batter
In a medium mixing bowl, whisk together the dry ingredients: flour through salt. Set aside. In a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the sugar and butter until light and fluffy.
– Add the eggs, vanilla, and buttermilk; mix on low until combined.
– Gradually add in the dry ingredients until no streaks of flour remain.
– Mix in the lemon juice and zest.
– Gently stir in the blueberries using a rubber spatula.
Step 3: Bake the Cake
Pour the batter into your prepared baking dish. Bake for about 40-45 minutes or until a toothpick inserted comes out with moist crumbs. Allow to cool completely in the pan.
Step 4: Drizzle with Glaze
For the glaze, combine powdered sugar with lemon juice in a bowl. Pour over your cooled cake once it’s ready. Let it harden before garnishing with fresh fruit if desired. Enjoy!

Common Mistakes to Avoid
Baking can be tricky, and even small mistakes can affect your Lemon Blueberry Sheet Cake. Here are some common errors to watch out for:
-
Not measuring ingredients accurately: Using too much or too little flour or sugar can completely alter the cake’s texture. Always use a kitchen scale or measuring cups for precise measurements.
-
Skipping the lemon zest: The zest adds a vibrant flavor that elevates the cake. Don’t skip it! Make sure to grate the outer layer of the lemon skin before juicing.
-
Overmixing the batter: This can lead to a dense cake instead of a light and fluffy one. Mix until just combined, and be gentle when folding in the blueberries.
-
Not letting the cake cool completely before glazing: If you glaze while warm, it will melt into the cake. Allow your Lemon Blueberry Sheet Cake to cool fully for a beautiful finish.
-
Using frozen blueberries without thawing: Frozen blueberries can add excess moisture to the batter. If using frozen, make sure to toss them in flour and add them while still frozen.
