- 2 ½ tsp baking powder

- 1 cup unsalted butter at room temperature
- 1 ½ cups sugar
- 4 large eggs
- 1 tsp vanilla extract
- 1 tbsp lemon zest

Step-by-Step: How to Bake Lemon Blueberry Cake
Step 1: Prepare and Warm-Up
Preheat the oven to 350°F (175°C). Grease and flour a 9-inch round or bundt cake pan. You may also line the bottom with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
Whisk flour, baking powder, baking soda, and salt together in a medium bowl.
Step 3: Cream the Butter and Sugar
Beat butter and sugar in a large bowl until light and fluffy. Add eggs individually, then combine the lemon juice, lemon zest, and vanilla extract.
Step 4: Mix Wet and Dry
Alternate between adding the flour mixture and buttermilk to the wet ingredients. Begin and end with the flour mixture.
Step 5: Fold in the Blueberries
Toss your blueberries in some flour so they won’t sink. Gently fold them into the batter. Step 6: Bake the Cake Pour the batter into the prepared pan and smooth out the top. Bake for 45–50 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool in the pan for 10–15 minutes before moving to a wire rack to cool fully.

Optional: Make a Lemon Glaze
After the cake is placed for cooling, stir together sugar and lemon juice until you get a well-mixed substance. Apply it on the cooled cake as an addition to the lemony taste.
Tips for the Best Lemon Blueberry Cake
- Of course, the best flavor will be provided by using fresh lemons, and lemon juice from a bottle may taste sharp and artificial.
- If the flour was incorporated into the batter, do not overmix it, otherwise, the cake will turn out to be heavy.
- If you want to, just be aware that the fact that the blueberries are frozen is alright—before mixing, just do not thaw them.
