Ingredients
For your Lemon Blueberry Sheet Cake, you will need the following ingredients:

How to Make Lemon Blueberry Sheet Cake: A Summery Delight for Every Occasion
Step 1: Prepare Your Oven
Start by preheating your oven to 350°F (175°C). Grease a 9×13 baking dish and line it with parchment paper. Ensure there’s an overhang on the long sides for easy removal later.
Step 2: Mix Dry Ingredients
In a medium bowl:
1. Whisk together the dry ingredients—flour, baking powder, baking soda, and salt. Set aside.
Step 3: Cream Butter and Sugar
Using a stand mixer fitted with a paddle attachment:
1. Cream the softened butter and granulated sugar together until light and fluffy.
2. This step is crucial for incorporating air into your batter to create a soft cake.
Step 4: Add Eggs and Wet Ingredients
Add eggs one at a time:
1. Mix well after each addition until fully incorporated.
2. Next, add vanilla extract and buttermilk on low speed until smooth.
Step 5: Combine Dry Ingredients with Wet Mixture
Gradually add your dry ingredients to the wet mixture:
1. Mix until just combined; be careful not to overmix as this could lead to a dense texture.
2. Finally, fold in lemon juice and zest for that burst of citrusy flavor.
Step 6: Incorporate Blueberries
Toss blueberries with one tablespoon of flour:
1. Gently fold them into your batter. This prevents them from sinking during baking.
Step 7: Bake Your Cake
Pour your batter into the prepared baking dish:
1. Spread it evenly using a spatula.
2. Bake for 40–45 minutes or until a toothpick inserted in the center comes out with moist crumbs.
Step 8: Cool Your Cake
Allow your cake to cool completely in the pan:
1. You can serve directly from the dish or lift it out using parchment paper overhang for easier slicing.
Step 9: Prepare Lemon Glaze
In a small bowl:
1. Whisk together powdered sugar and lemon juice until smooth; it should be pourable yet thick enough to coat a spoon.
Step 10: Glaze Your Cake
Drizzle your glaze generously over the cooled cake:
1. Allow it to drip down the sides before letting it set completely before slicing.
Enjoy your delicious Lemon Blueberry Sheet Cake at gatherings or as an everyday treat!

How to Perfect Lemon Blueberry Sheet Cake: A Summery Delight for Every Occasion
Making the perfect Lemon Blueberry Sheet Cake requires attention to detail. Here are some tips to ensure your cake turns out beautifully every time.
- Use Room Temperature Ingredients: Bring eggs, butter, and buttermilk to room temperature before mixing. This helps achieve a smoother batter and better rise.
- Don’t Overmix: Mix the batter until just combined to prevent a dense texture. Overmixing can lead to toughness in your cake.
- Fresh Blueberries Matter: Always use fresh blueberries for the best flavor and texture. Frozen berries can work, but they may release more moisture during baking.
- Check Oven Temperature: Ensure your oven is calibrated correctly; an inaccurate temperature can affect baking times and cake texture.
- Cool Completely Before Glazing: Let the cake cool completely before adding glaze. This prevents it from melting into the cake and ensures a nice finish.
- Store Properly: Keep leftovers in an airtight container at room temperature for up to three days or in the fridge for up to a week to maintain freshness.
