Ingredients
You’ll need the following ingredients for this yummy cake:
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt
- 1 cup butter (2 sticks), softened
- 1 1/2 cups granulated sugar
- Juice and zest of 2 lemons (about 1/4 cup lemon juice)
- 4 large eggs
- 1 cup buttermilk
- 2 teaspoons vanilla extract
- 1 1/2 cups fresh blueberries, tossed with 1 tablespoon flour
- 2 1/2 cups powdered sugar
- 1/3 cup lemon juice
Directions
- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease a 9×13 baking dish and then line it with parchment paper for easy removal.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside for now.
- In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This should take about 3-5 minutes.
- Add the eggs, vanilla extract, and buttermilk to the butter mixture. Blend on low speed until everything is combined.
- Gradually mix in the dry ingredient mixture until just combined. Avoid overmixing, as this can make the cake tough!
- Add in the lemon juice and lemon zest, mixing well. Gently fold in the blueberries, which you’ve tossed with that tablespoon of flour — this helps keep them from sinking to the bottom of the cake.
- Pour the batter into the prepared baking dish and spread it evenly. Bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cake to cool completely in the pan before you drizzle the glaze on top.
- To make the glaze, whisk together the powdered sugar and lemon juice until you achieve a smooth consistency. Pour it over the cooled cake.
- Optional: Garnish with fresh blueberries for an extra pop of color and flavor before serving.

How to Serve Lemon Blueberry Sheet Cake
Serving this delightful cake is as easy as pie! Slice it into generous squares and present it with a light dusting of powdered sugar or a dollop of whipped cream. For a refreshing twist, serve it with a scoop of vanilla ice cream on the side — the creaminess pairs perfectly with the tartness of the cake.
Consider adding some fresh mint leaves as a garnish for a pop of color and a hint of freshness. If you’re feeling extra, why not serve it with a refreshing glass of iced tea or lemonade? But really, this cake can be enjoyed any time of the day!
Keeping Your Lemon Blueberry Sheet Cake Fresh
Once you’ve treated yourself to this yummy cake, you’ll want to make sure you can enjoy it for days to come! To store your leftover cake, cover it tightly with plastic wrap or foil and keep it at room temperature for up to 3 days. If you want to keep it longer, you can refrigerate it, where it will stay fresh for about a week.
For longer storage, consider freezing the cake. Simply wrap the entire cake or individual slices tightly in plastic wrap and then place them in a freezer-safe bag. It can stay fresh in the freezer for up to 3 months! When you’re ready to indulge again, thaw it in the fridge overnight, and then warm it slightly before serving for that fresh-baked taste.
Tips to Make Lemon Blueberry Sheet Cake
- Use Fresh Ingredients: For the best flavor, opt for fresh blueberries and real lemon juice. Bottled lemon juice just doesn’t cut it!
- Don’t Overmix: When combining the wet and dry ingredients, mix until just incorporated. Overmixing will toughen the cake.
- Keep Blueberries Plump: Tossing your blueberries in flour helps prevent them from sinking to the bottom of the batter.
- Test for Doneness: Oven temperatures can vary, so check your cake a few minutes before the minimum baking time to avoid overbaking.
Delicious Variations of Lemon Blueberry Sheet Cake
If you want to switch things up, there are plenty of tasty twists you can try! Consider adding a touch of cream cheese to your frosting for a delightful tang or folding in some crushed nuts, like pecans or walnuts, for extra texture.
For a more decadent version, swap the buttermilk with a flavored yogurt, such as lemon or blueberry-flavored. You could also substitute the blueberries with raspberries or blackberries, giving your cake a different fruity flair.
FAQs
Can I use frozen blueberries instead of fresh ones?
Yes, you can! Just make sure to thaw and drain them before tossing them in flour and adding them to your batter.
Can I make this cake ahead of time?
Absolutely! This cake stores wonderfully, making it perfect for prepping in advance. You can bake it the day before and glaze it right before serving.
Is there an alternative for buttermilk?
You can make your own buttermilk by mixing one cup of milk with one tablespoon of vinegar or lemon juice. Let it sit for 5-10 minutes before using.
There you have it! I hope you enjoy making and sharing this delightful Lemon Blueberry Sheet Cake as much as I do. This recipe is a celebration of flavor and joy, perfect for any occasion. So let’s preheat those ovens, and get ready to create something wonderful together! Happy baking!
