Ingredients

• Flour: The base of the cake that provides structure and texture.
• Baking Powder: Helps the cake rise and become light and fluffy.
• Salt: Enhances the flavors and balances sweetness.
• Butter: Adds richness and moisture to the cake.
• Sugar: Sweetens the cake and creates a delicate crumb.
• Eggs: Binds the ingredients and adds moisture.
• Vanilla Extract: Adds depth of flavor.
• Buttermilk: Contributes to the cake’s tenderness and slight tang.
• Lemon Juice & Zest: Brings bright citrus flavor and fragrance.
• Blueberries: Provide bursts of sweet flavor and moisture throughout the cake.
• Powdered Sugar: Used in the glaze for smooth sweetness.

Alternative Ingredient Suggestions

• Buttermilk can be replaced with whole milk mixed with a tablespoon of vinegar if you don’t have buttermilk on hand.
• You can swap the fresh blueberries for frozen ones, but be sure to coat them lightly in flour to prevent them from sinking to the bottom of the cake during baking.
• For a dairy-free version, substitute the butter with plant-based butter or coconut oil and use almond milk in place of buttermilk.

Step-by-Step Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper, allowing an overhang for easy removal.
  2. In a medium bowl, whisk together the dry ingredients: flour, baking powder, and salt. Set aside.
  3. In a stand mixer (or with a hand mixer), cream together the butter and sugar until light and fluffy. This step is essential for a light texture.
  4. Add in the eggs, vanilla extract, and buttermilk, mixing on low speed until fully incorporated.
  5. Slowly add the dry ingredients to the wet mixture, mixing until the batter is smooth and no streaks of flour remain.
  6. Stir in the fresh lemon juice and zest, which will add a fragrant citrus note to your cake.
  7. Gently fold in the blueberries using a spatula to avoid breaking them.
  8. Pour the batter into the prepared baking dish and smooth the top. Bake for 40 to 45 minutes or until a toothpick comes out with moist crumbs (not wet batter).
  9. Let the cake cool completely in the pan. If you used parchment paper, lift the cake out gently to make glazing easier.
  10. For the glaze, mix the powdered sugar and lemon juice until smooth. Drizzle over the cooled cake and let it set.
  11. Once the glaze has hardened, garnish with fresh blueberries or additional lemon zest for extra flavor and decoration.

Tips & Tricks

• To check if your cake is done, insert a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, it’s ready.
• If you prefer a thicker glaze, add more powdered sugar. For a more tart glaze, increase the lemon juice.
• Store leftovers in an airtight container at room temperature for up to 2-3 days. If you prefer a colder, firmer texture, refrigerate the cake.

Pairing Ideas and Variations

This Lemon Blueberry Sheet Cake pairs wonderfully with whipped cream, a scoop of vanilla ice cream, or even a dollop of Greek yogurt for a tangy twist. For a more decadent version, you could add a layer of lemon curd between the cake and glaze.
