Serving and Storage Tips

To serve, allow the cake to cool completely before drizzling on the glaze. For an extra special touch, garnish each slice with a few fresh blueberries or a dusting of powdered sugar.

Store leftovers in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate the cake for up to 5 days. Simply bring to room temperature before serving for the best texture and flavor. The cake also freezes well. Wrap individual slices tightly and store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator or at room temperature before serving.

Ingredients

• 2 cups all-purpose flour
• 1 and 1 half teaspoons baking powder
• 1 half teaspoon baking soda
• 1 half teaspoon salt
• 1 cup granulated sugar
• 2 large eggs
• 1 cup whole milk
• 1 half cup vegetable oil
• 1 teaspoon pure vanilla extract
• 2 tablespoons lemon zest
• 3 tablespoons fresh lemon juice
• 1 and 1 half cups fresh or frozen blueberries

Lemon Glaze

• 1 cup powdered sugar
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 tablespoon whole milk

Equipment

• 9×13 inch baking pan
• Mixing bowls
• Electric hand mixer or stand mixer
• Rubber spatula
• Whisk
• Zester or fine grater
• Measuring cups
• Measuring spoons
• Wire cooling rack

Instructions

1. Step 1: Preheat oven to 350 degrees Fahrenheit. Grease or line a 9×13 inch baking pan with parchment paper.
2. Step 2: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This builds the cake’s structure, so do not skip the sifting step if your flour is clumpy.
3. Step 3: In a large mixing bowl, beat the sugar and eggs together on medium-high speed until the mixture is pale and fluffy. This helps incorporate air for a soft crumb.
4. Step 4: Add the milk, oil, vanilla, lemon zest, and lemon juice. Mix on low speed until smooth. Use freshly squeezed juice and zest for the most vibrant lemon flavor.
5. Step 5: Gradually add the dry ingredients to the wet mix. Blend until just combined. Overmixing will make the cake tough, so stop mixing when you no longer see dry flour.
6. Step 6: Gently fold in the blueberries using a rubber spatula. If using frozen blueberries, toss them in a tablespoon of flour first to help prevent them from sinking.
7. Step 7: Pour the batter into the prepared baking pan and smooth the top evenly with the spatula. Give the pan a gentle tap on your counter to pop any large air bubbles.
8. Step 8: Bake for 33 to 36 minutes or until a toothpick inserted in the center comes out clean. The top should be golden and slightly springy to the touch.
9. Step 9: Let the cake cool completely in the pan on a wire rack. If you glaze it while warm, the glaze will soak in too much instead of creating a pretty finish.
10. Step 10: To make the glaze, whisk together the powdered sugar, lemon juice, zest, and milk until smooth. Drizzle generously over the cooled cake and let set before slicing.

Recipe Notes

If using frozen blueberries, do not thaw before adding them to the batter to prevent streaking. Lightly tossing them in a tablespoon of flour before folding into the batter can help distribute them more evenly.

For a slightly healthier version, substitute half the vegetable oil with unsweetened applesauce. The cake will be a bit denser but still moist and flavorful.

To enhance the glaze, add a pinch of salt or a drop of vanilla for extra depth. Let the glaze sit for a minute to thicken before drizzling.
