How to Make Lemon Blueberry Sheet Cake

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease a sheet pan with cooking spray or line it with parchment paper – we want no sticky situations here!

Step 2: Mix Dry Ingredients

In a large mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, and salt until combined. This is where we build our base!

Step 3: Combine Wet Ingredients

In another bowl, combine vegetable oil, eggs, lemon zest, lemon juice, and vanilla extract. Whisk until smooth – just like your favorite playlist on repeat.

Step 4: Combine Mixtures

Pour the wet mixture into the dry ingredients and stir gently until just combined – don’t overmix! Gently fold in those glorious blueberries so they’re evenly distributed throughout.

Step 5: Bake

Pour the batter into your prepared sheet pan and spread it evenly. Bake in your preheated oven for about 25-30 minutes or until golden brown and a toothpick inserted into the center comes out clean.

Step 6: Cool and Frost

Once baked, remove from oven and let cool completely on a wire rack. If desired, whip up some frosting using agar-agar as a gelling agent mixed with lemon juice and powdered sugar before spreading it generously over your cooled cake.

Transfer to plates and serve slices garnished with extra blueberries or lemon slices for that wow factor! Enjoy every mouthwatering bite of this delightful Lemon Blueberry Sheet Cake!

FAQs:

How do I store Lemon Blueberry Sheet Cake?

To store your Lemon Blueberry Sheet Cake, place it in an airtight container at room temperature for up to three days. If you need to keep it longer, consider refrigerating it, where it can last for about a week. For extended storage, freeze individual slices wrapped in plastic wrap and then aluminum foil. This method preserves the cake’s moisture and flavor, allowing you to enjoy it later without losing its delightful taste.

Can I use frozen blueberries in this recipe?

Yes, you can definitely use frozen blueberries for Lemon Blueberry Sheet Cake. Just ensure that you do not thaw the blueberries before adding them to the batter. Frozen berries can add moisture and maintain their shape during baking, resulting in a deliciously fruity flavor. Keep in mind that they may slightly change the cake’s color but will still yield a fantastic taste.

What can I substitute for eggs in this Lemon Blueberry Sheet Cake?

If you’re looking to substitute eggs in your Lemon Blueberry Sheet Cake, consider using unsweetened applesauce or mashed bananas. Typically, 1/4 cup of applesauce or half a mashed banana replaces one egg effectively. These substitutes will help bind the ingredients together while keeping the cake moist and flavorful without altering its texture too much.

How can I enhance the lemon flavor in my cake?

To enhance the lemon flavor in your Lemon Blueberry Sheet Cake, use freshly grated lemon zest along with fresh lemon juice. The zest contains essential oils that deliver a more vibrant lemon essence than juice alone. Additionally, incorporating a lemon glaze on top after baking can further amplify that zesty goodness, making every bite refreshing and delicious.

Conclusion for Lemon Blueberry Sheet Cake:

In summary, this delightful Lemon Blueberry Sheet Cake is perfect for any occasion, combining fresh flavors with a moist texture. Utilizing simple ingredients and alternative substitutes ensures everyone can enjoy this treat without dietary restrictions.
