This Blueberry Lemon Butter Cake recipe combines tangy lemon zest with sweet blueberries in a rich, buttery batter. The moist cake is topped with a zesty lemon glaze, enhancing its refreshing flavor. Simple to prepare, it's perfect for brunch or dessert, offering a delightful balance of sweetness and citrus in every bite.
In a large bowl, combine the lemon cake mix, eggs, vanilla extract, lemon zest, and half of the softened butter (1 stick). Use an electric mixer or whisk to blend the ingredients until smooth and well combined.
Add Blueberries and Powdered Sugar:
Gently fold in half of the blueberries and the 2 cups of powdered sugar into the batter. Be careful not to crush the berries.
Prepare the Cake Pan and Bake:
Preheat the oven to 350°F (175°C). Grease your cake pan with some butter or cooking spray. Pour the batter into the pan and smooth the top with a spatula. Sprinkle the remaining blueberries on top. Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.
Cool the Cake:
Remove the cake from the oven and place it on a cooling rack. Let it cool completely in the pan for about 20 minutes, then carefully invert the cake onto the rack to cool fully.
Finish and Serve:
Once cooled, lightly dust the cake with powdered sugar. Slice and serve as is for a buttery, moist lemon-blueberry treat.
