How to Make Lemon Blueberry Sheet Cake
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. This ensures that your cake bakes evenly from the start.
Step 2: Prepare the Cake Batter
- In your stand mixer or large mixing bowl, add the lemon cake mix, instant pudding mix, and flour.
- Mix these dry ingredients together until well combined.
- Add in the remaining cake batter ingredients: oil, eggs, water, vanilla, sour cream, and lemon zest.
- Mix on low speed for 1 minute. Scrape down the sides with a rubber spatula.
- Continue mixing on medium speed for an additional 2 minutes until the batter is thick and glossy.
Step 3: Prepare the Baking Pan
Spray a large cookie sheet (11×17 pan) with cooking spray to prevent sticking. Pour the prepared batter evenly over the pan.
Step 4: Make the Blueberry Swirl
- In a large glass measuring cup, combine blueberry pie filling, melted butter, vanilla, and salt.
- Heat this mixture in the microwave for about 1 minute; warm filling is easier to work with.
Step 5: Create Swirls in the Batter
Drop small spoonfuls of the blueberry mixture onto the top of the cake batter, spacing them about 1 inch apart. Using a butter knife, gently swirl through both batters to create a marbled effect.
Step 6: Bake Your Cake
Bake in preheated oven for approximately 20 minutes or until a toothpick inserted into the center comes out clean. Allow cooling for about 5 minutes after baking.
Step 7: Prepare Lemon Glaze While Cooling
While your cake cools slightly, whisk together all ingredients for the Lemon Glaze until smooth. The glaze should be thin enough to drizzle but not thick like frosting.
Step 8: Poke Holes for Glaze Absorption
When your cake is still warm, use a fork to poke holes every 2-3 inches across its surface. This allows the glaze to seep into the cake.
Step 9: Drizzle with Lemon Glaze
Immediately drizzle your prepared Lemon Glaze all over the top of the warm cake while spreading it out evenly with a knife.
Enjoy your delicious Lemon Blueberry Sheet Cake that’s sure to be a hit at any gathering!

How to Perfect Lemon Blueberry Sheet Cake
To ensure your Lemon Blueberry Sheet Cake turns out perfectly every time, follow these tips. They will help you achieve that moist texture and vibrant flavor everyone loves.
- Use fresh ingredients: Always use fresh eggs, lemons, and blueberries. This enhances the flavor and moisture of your cake.
- Don’t overmix: When combining your batter, mix just until combined to avoid a dense cake. A thick batter is key!
- Check doneness carefully: Use a toothpick to test if your cake is done; it should come out clean without any wet batter sticking to it.
- Cool before glazing: Allow the cake to cool slightly before adding the lemon glaze. This prevents it from melting into the cake.
- Adjust sweetness: If you prefer less sweetness, reduce the powdered sugar in your glaze or add more lemon juice for tartness.
- Experiment with flavors: Add other berries or citrus zests to customize your cake. Creativity can lead to exciting new flavors!
