Instructions
- Preheat and Prepare: Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch pan or two 9-inch round pans. Line with parchment if desired.
- Infuse Lemon Sugar: In a large bowl, rub lemon zest into granulated sugar with your fingertips for 1 minute until fragrant.
- Cream Butter and Sugar: Add softened butter to lemon sugar. Beat on medium-high speed for 3-4 minutes until light and fluffy.
- Add Eggs: Beat in eggs one at a time, mixing well after each addition. Add vanilla with the last egg.
- Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, and salt.
- Mix Liquid Ingredients: In another bowl, whisk together sour cream, milk, and lemon juice.
- Alternate Mixing: With mixer on low, add flour mixture in three additions, alternating with sour cream mixture in two additions. Begin and end with flour. Mix only until just combined.
- Fold in Berries: Toss blueberries with 2 tablespoons flour. Gently fold into batter using 8-10 broad strokes.
- Bake: Pour batter into prepared pan(s). Bake 9×13 for 45-55 minutes, or 9-inch rounds for 30-35 minutes, until toothpick comes out clean.
- Cool: Cool in pan for 15 minutes, then remove to wire rack to cool completely.
