How To Make Blueberry Cake
Preparation: Preheat your oven to 350°F. Prepare a 10-12 inch rectangular baking dish by lining it with parchment paper or a light coating of vegan butter or non-stick spray.
Batter Preparation: In your large mixing bowl, whisk together the milk, melted butter, maple syrup, and vanilla. Sift in baking powder, baking soda, salt, cinnamon, and flour. Stir gently until combined. Carefully fold in blueberries ensuring even distribution.
Baking: Pour the batter into the prepped baking dish, spreading evenly. Bake for approximately 30 minutes, or until a toothpick comes out clean and the edges turn golden.
Frosting Preparation: While the cake cools, prepare the frosting. Using an electric hand mixer or a whisk in a medium bowl, combine powdered sugar, cream cheese, and melted butter until smooth and creamy.
Assembly: Once the cake has completely cooled, spread the cream cheese frosting over the top. Slice, serve, and enjoy the berry goodness!
Frequently Asked Questions
Store leftover blueberry cake in an airtight container in the refrigerator for up to 5 days. Before serving again, you can let it come to room temperature for a softer texture or enjoy it chilled. If the cake has cream cheese frosting, it's especially important to refrigerate to maintain the frosting's freshness and consistency.
Absolutely! The frosting adds an additional layer of sweetness and texture, but if you prefer a simpler, less sweet treat, or just want to enjoy the natural flavors of the blueberry sheet cake, you can definitely skip the frosting.
The blueberry sheet cake on its own is moist and flavorful, especially with the infusion of maple syrup and blueberries. It tastes a lot like a blueberry muffin. Leaving off the frosting can also make it feel a bit lighter and potentially more suitable for breakfast or a snack, rather than a dessert.
If you want a hint of added moisture or flavor without a full frosting, you could do a light drizzle of maple syrup or a sprinkle of powdered sugar on top.
Absolutely! You can adapt the Blueberry Sheet Cake recipe to be baked in a loaf pan. Here's how:
Adjust the Baking Time: Loaf pans are typically deeper than sheet pans, so you'll need to increase the baking time. While the original recipe calls for 30 minutes in a sheet pan, you might need to bake a loaf for 45-60 minutes, depending on the depth of your loaf pan. Start checking for doneness around the 45-minute mark by inserting a toothpick or a knife into the center. If it comes out clean or with a few crumbs, it's done. If not, give it more time and keep checking at intervals.
Monitor the Oven Temperature: It's a good idea to keep an oven thermometer inside to ensure the temperature is consistent. A loaf might benefit from slightly lower oven temperatures after the initial rise to prevent over-browning on the top while the center gets fully baked. If you notice the top browning too quickly, you can loosely cover it with aluminum foil for the remainder of the baking time.
Cooling Time: Once baked, let the loaf rest in the pan for about 10-15 minutes, then transfer it to a wire rack to cool completely. This will help the loaf maintain its structure and prevent it from becoming too moist or soggy at the bottom.
Frosting: Once the loaf has cooled down, you can proceed to frost it as per the original instructions.
Converting a sheet cake recipe to a loaf is a fun way to enjoy the same flavors in a different form, and it can be convenient for slicing and serving for breakfast or snack time. Just remember that baking is a bit of an art and science combined, so the first attempt at a new form might be a learning experience. Enjoy your blueberry loaf cake!
