Ingredients Needed :
Dry ingredients
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt
Wet ingredients
- 1 cup butter (2 sticks), softened
- 1 1/2 cups granulated sugar
- 4 large eggs
- 1 cup buttermilk
- 2 teaspoons vanilla extract
- Juice and zest of 2 lemons (about 1/4 cup lemon juice)
Fruit
- 1 1/2 cups fresh blueberries, tossed with 1 Tbs flour
Glaze
- 2 1/2 cups powdered sugar
- 1/3 cup lemon juice
Step-by-Step Instructions :
- Preheat the oven to 350 degrees F. Grease a 9×13 baking dish, and line with parchment paper.
- In a medium mixing bowl, whisk together the dry ingredients (flour through salt). Set aside.
- In a stand mixer, cream together the sugar and butter until light and fluffy. Add the eggs, vanilla, and buttermilk, mixing on low until incorporated.
- Add the dry ingredients and mix until no streaks of flour remain. Then mix in the lemon juice and zest. Gently stir in the blueberries.
- Pour the batter into the prepared baking dish and bake for 40-45 minutes or until a toothpick comes out with moist crumbs. Allow the cake to cool completely.
- For the glaze, combine powdered sugar and lemon juice, then pour over the cooled cake. Let set before serving.
Serving Suggestions Lemon Blueberry Sheet Cake
- Serve with a dusting of extra lemon zest and a few fresh blueberries on top.
- Add a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
- For brunch, offer slices alongside savory items or warm French Toast Pancakes to round out the table.
- Cut into small squares for finger-food portions at gatherings.
Tips for Success Lemon Blueberry Sheet Cake
- Toss the blueberries in a tablespoon of flour to prevent them from sinking to the bottom.
- Room-temperature eggs, butter, and buttermilk blend more evenly for a smooth batter.
- Don’t overmix once you add the dry ingredients — stop when flour streaks disappear to keep the cake tender.
- Test with a toothpick near the center; pull out when it has moist crumbs, not wet batter.
- For extra lemon punch, fold in a teaspoon more lemon zest. For a twist, try pairing components with a blueberry matcha recipe for a layered brunch menu.
variation (if any)
- Lemon Poppy Seed: add 1–2 tablespoons poppy seeds to the batter.
- Gluten-free: swap the all-purpose flour for a 1:1 gluten-free baking mix and check texture — you may need a touch less buttermilk.
- Frozen blueberries work in a pinch; do not thaw and toss with flour while still frozen.
FAQs
Q: Can I use frozen blueberries?
A: Yes. Keep them frozen, toss in the tablespoon of flour, and fold in; baking time should be the same but watch for a slightly moister center.
Q: How long will this cake keep?
A: Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. Bring to room temp before serving for best texture.
Q: Can I make this ahead and freeze it?
A: Yes. Freeze unglazed baked cake wrapped tightly for up to 3 months. Thaw, then glaze before serving.
Q: Can I halve the recipe for a smaller pan?
A: You can, but adjust baking time and pan size (try an 8×8 or 9-inch pan) and start checking for doneness at 25–30 minutes.
