Ingredients

• 3 cups all-purpose flour
• 2 tsp baking powder
• 1/2 tsp baking soda
• 1 1/4 tsp salt
• 1 cup butter (2 sticks), softened
• 1 1/2 cups granulated sugar
• 2 units juice and zest of lemons
• 4 large eggs
• 1 cup buttermilk
• 2 tsp vanilla extract
• 1 1/2 cups fresh blueberries
• 1 tbsp flour (for tossing berries)
• 2 1/2 cups powdered sugar
• 1/3 cup lemon juice (for glaze)

Instructions

1

Set your oven temperature to 350 degrees F. Lightly grease a 9×13-inch baking pan, then line it with sheets of parchment paper, ensuring it drapes over both of the longer sides. This extra overhang allows you to lift the finished dessert out smoothly!

2

Combine the flour, baking powder, baking soda, and salt in a medium-sized bowl using a whisk, then set it aside. In the bowl of your stand mixer equipped with a paddle (or using a portable hand mixer), beat the sugar and softened butter together until the mixture is airy and light. Incorporate the eggs, vanilla extract, and buttermilk, mixing on a low setting until just blended. Add your prepared dry flour blend, running the mixer only until the powdery streaks completely disappear. Gently fold in the fresh lemon juice and citrus zest, then use a flexible spatula to carefully fold the flour-dusted blueberries into the completed batter.

3

Spread the cake batter evenly into your prepared 9×13-inch pan and bake for roughly 40 to 45 minutes, testing with a toothpick until it comes out clean with just a few moist crumbs attached. Let the cake cool down entirely. You can lift the whole slab out using the paper handles before icing, or simply leave it directly in the baking dish for slicing. Both methods work perfectly!

4

To create the topping: whisk the confectioners' sugar and lemon juice together until completely smooth, then spread it evenly across the top of your cooled dessert. Wait for the icing layer to set firm, then decorate with extra fresh berries before slicing into squares!

Frequently Asked Questions

Can I use frozen berries for this recipe? Yes, frozen berries work fine in this Blueberry Sheet Cake Recipe! To prevent your batter from turning entirely purple, do not thaw them. Toss them directly with the tablespoon of flour while frozen and fold them into the Lemon Blueberry Sheet Cake batter quickly at the final second. How should I store leftovers of this slab cake? Keep slices of this Lemon Blueberry Slab Cake Recipe in an airtight container at room temperature for up to 2 days, or place them in the refrigerator for up to 5 days. Because it is a Lemon Sheet Cake With Glaze, chilling helps the sweet icing stay perfectly set. Can I substitute buttermilk if I don't have it on hand? Absolutely! If you're building a Summer Sheet Cake and ran out of buttermilk, make a quick homemade version. Stir 1 tablespoon of fresh lemon juice or white vinegar into 1 cup of whole milk and let it stand for 5 minutes before mixing into your Summer Day Sheet Cake base.
