It’s simple enough for a weeknight treat yet impressive enough for a crowd—trust me, one bite and you’ll be hooked on its sunny charm.
To whip up this delightful Lemon Blueberry Sheet Cake with Lemon Glaze, you’ll need a handful of pantry staples and fresh berries. Each ingredient plays a key role in delivering that tender crumb, bright flavor, and gorgeous glaze.
Baking this sheet cake is a breeze once your mise en place is set. You’ll whisk dry ingredients separately, cream butter and sugar until fluffy, blend in eggs, vanilla, milk, and lemon zest, then fold in blueberries coated in flour so they stay suspended. After the simple bake, you’ll whip up a tangy lemon glaze to drizzle over the warm cake, creating a glossy finish that seeps into every nook. Follow these detailed steps for a foolproof slice of sunshine.
1. Preheat the oven to 350 °F and grease a 13×9-inch baking pan. Make sure the oven rack is in the middle position for even baking.
2. Whisk dry ingredients in a medium bowl: combine 2 cups of flour, 1 tablespoon baking powder, and 1/2 teaspoon salt until evenly distributed.
3. Cream the butter and sugar in a large bowl using a hand mixer or stand mixer until the mixture is light in color and fluffy, about 3–4 minutes.
4. Incorporate the eggs by adding them one at a time to the butter-sugar mixture, beating well after each addition. Then stir in 1 teaspoon vanilla extract, the zest of 2 lemons, and 1/2 cup whole milk until the batter is smooth.
5. Combine wet and dry by gradually adding the flour mixture to the batter in batches, mixing on low speed just until no streaks of flour remain—avoid overmixing to keep the cake tender.
6. Prep the blueberries by tossing 1 cup of fresh berries with 1 tablespoon of flour in a small bowl. Gently fold them into the batter so they stay suspended during baking.
7. Transfer and bake by spreading the batter evenly in the prepared pan. Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean and the edges begin to pull away slightly.
8. Make the glaze while the cake bakes: whisk together 1 1/2 cups powdered sugar, 2 tablespoons lemon juice, and 1 teaspoon milk until you have a smooth, pourable consistency.
9. Cool briefly by removing the cake from the oven and letting it rest in the pan for 10 minutes. This helps the crumbs settle before glazing.
10. Drizzle the glaze over the warm cake, allowing it to drizzle into the nooks. Let it set completely before slicing into generous pieces.

Here are some quick answers to common curiosities about this cake:
It takes about 45 to 50 minutes in total. Preparation—including mixing dry ingredients, creaming butter and sugar, beating in eggs, zesting lemons, tossing blueberries, and preheating the oven—takes around 15 minutes. Baking requires 25 to 30 minutes, followed by a 10-minute cooling period before drizzling the glaze and letting it set.
Yes, you can use frozen blueberries without thawing to minimize bleeding. Toss them in the tablespoon of flour as directed, then gently fold into the batter. Baking time may increase by 2 to 3 minutes to account for extra moisture, so keep an eye on doneness with the toothpick test.
Coating the blueberries in a tablespoon of flour before folding them into the batter creates a thin barrier that helps them stay suspended throughout the cake as it bakes. Be sure to add the flour, toss until evenly coated, and then fold gently so you don’t break the berries.
For a richer taste, substitute an equal amount of buttermilk for the whole milk; this also adds a slight tang that complements the lemon. For a dairy-free version, use unsweetened almond or oat milk in the same quantity. The texture may be slightly different, but the cake will still bake up moist and flavorful.
Insert a toothpick into the center of the cake—if it comes out clean or with a few moist crumbs (but no wet batter), the cake is done. The edges should pull away slightly from the pan and the top will be lightly golden. Avoid overbaking to keep the cake tender.
You can mix the dry and wet ingredients separately and store them in airtight containers in the refrigerator for up to 24 hours. When ready to bake, combine them, toss the blueberries in flour, fold them in, and proceed with baking. Note that baking powder’s rise may be slightly reduced, so bake promptly after mixing for best results.
Store any leftover cake slices in an airtight container at room temperature for up to 3 days. If you need to keep it longer, tightly wrap pieces in plastic wrap and freeze for up to 2 months; thaw at room temperature before serving. Rewarm slices gently in a low-temperature oven (about 300 °F) for 5 minutes if you prefer them warm.
