How to Make Lemon Blueberry Sheet Cake
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. This step ensures that your cake bakes evenly.
Step 2: Prepare the Cake Batter
- In a stand mixer or large mixing bowl, combine the lemon cake mix, instant lemon pudding, and flour. Toss together to mix well.
- Add the remaining ingredients for the cake batter: oil, eggs, water, vanilla, sour cream, and lemon zest. Mix on low speed for 1 minute.
- Scrape down the sides of the bowl with a rubber spatula. Continue mixing on medium speed for an additional 2 minutes until thick and glossy.
Step 3: Prepare the Baking Pan
Spray your large cookie sheet with cooking spray to prevent sticking. Pour the cake batter evenly over the pan.
Step 4: Make the Blueberry Swirl
In a glass measuring cup, combine the blueberry pie filling, melted butter, vanilla, and dash of salt. Heat in the microwave for about 1 minute until warm.
Step 5: Create Swirls in Cake Batter
Drop small spoonfuls of the blueberry mixture onto the top of your cake batter about 1 inch apart. Use a butter knife to gently swirl through both mixtures creating a marbled effect.
Step 6: Bake the Cake
Place in preheated oven and bake for approximately 20 minutes or until a toothpick inserted into the center comes out clean. Allow cooling for 5 minutes after baking.
Step 7: Prepare Lemon Glaze While Baking
While your cake is cooling, whisk together all ingredients for the Lemon Glaze until smooth and thin.
Step 8: Poke Holes in Cake
Using a fork, poke holes into the warm cake every 2-3 inches apart. This helps absorb some of that delicious glaze!
Step 9: Drizzle Lemon Glaze Over Cake
Immediately drizzle your prepared Lemon Glaze over top of the warm cake, spreading it out evenly with a knife as needed. Enjoy your delightful creation!

- Don’t overmix – Mix just until combined to keep your cake light and fluffy.
- Check oven temperature – Ensure your oven is properly calibrated; an incorrect temperature can lead to uneven baking.

Common Mistakes to Avoid
Baking a Lemon Blueberry Sheet Cake can be easy, but there are common pitfalls to watch out for. Here are some mistakes to avoid:
- Using cold ingredients – Always ensure your eggs and sour cream are at room temperature. This helps the batter mix smoothly.
- Overmixing the batter – Mixing too much can make the cake tough. Aim for just enough mixing to combine the ingredients.
