Lemon Blueberry Sheet Cake
Ingredients
Method
Step 1: Prep Your Pan & Oven
Set your oven to 350°F (175°C). Lightly grease a 9×13-inch pan, then line it with parchment paper, leaving extra hanging over the sides for easy lifting later.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Keep this mixture aside.
Step 3: Cream Butter & Sugar
Using a stand mixer (or hand mixer), beat the butter and sugar until pale and fluffy. This step builds the cake’s soft texture—don’t rush it!
Step 4: Add Wet Ingredients
Mix in the eggs one at a time. Then add vanilla extract and buttermilk. Blend on low speed until smooth and combined.
Step 5: Combine Batter
Gradually add the dry mixture into the wet ingredients. Mix just until no dry spots remain. Stir in lemon zest and juice.
Step 6: Fold in Blueberries
Gently fold the floured blueberries into the batter using a spatula. This keeps them from sinking.
Step 7: Bake
Spread the batter evenly in your prepared pan. Bake for 40–45 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Step 8: Cool Completely
Let the cake cool fully in the pan before removing or glazing.
