Instructions
 

  • Preheat oven to 350°F (175°C). Grease and line two 8-inch pans. Toss blueberries with 1 Tbsp flour.
  • Whisk flour, baking powder, baking soda, and salt together.
  • Cream butter and sugar until light and fluffy. Add eggs, lemon zest, lemon juice, and vanilla, mixing well.
  • Add half the dry ingredients. Add buttermilk. Add remaining dry mix. Mix until just combined. Fold in blueberries.
  • Divide batter in pans. Bake 25–30 min, or until a toothpick comes out clean. Cool 10 min, then transfer to racks.
  • For frosting: Beat cream cheese and butter. Add powdered sugar, lemon zest, lemon juice, vanilla, and salt. Beat until fluffy.

Notes

For a lighter cake, do not overmix the batter. You can substitute Greek yogurt for buttermilk if desired. Cake stays moist for days!
