  • 1 tablespoon Lemon zest - Fresh, organic if possible
  • 2 tablespoon Lemon juice - Freshly squeezed
  • 1 teaspoon Vanilla extract
  • 1 ½ cups Blueberries - Fresh or frozen (don’t thaw)
Frosting Ingredients
  • 8 oz Cream cheese - Full-fat, softened
  • ½ cup Unsalted butter - Softened
  • 3 cups Powdered sugar - Sifted
  • 1 tablespoon Lemon juice
  • 1 teaspoon Lemon zest
  • 1–2 tablespoon Heavy cream - Adjust for consistency

Equipment

  • 8 or 9-inch round pans (Use parchment circles)
  • Stand or Hand Mixer (For creaming butter and sugar)
  • Microplane zester (For lemon zest)
  • Mixing bowls (Separate for wet and dry mixes)
  • Rubber spatula (For folding in blueberries)
  • Wire cooling rack (Essential for cooling cakes)

Method
 

  1. Preheat oven to 350°F. Line pans with parchment paper and grease sides. Zest and juice lemons; wash and dry blueberries.
  2. Beat butter, oil, and sugar until light and fluffy (3–4 mins). Add eggs one at a time, mixing after each.
  3. Mix in lemon zest, juice, and vanilla.
  4. In a separate bowl, whisk flour, baking powder, soda, and salt. Alternate adding dry ingredients and buttermilk to the wet mix.
  5. Toss blueberries with reserved flour. Fold into batter gently.
  6. Divide batter between pans, tap to release air bubbles. Bake for 25–30 minutes. Cool in pans for 10 minutes, then on racks.
  7. Beat cream cheese and butter until smooth. Add powdered sugar, lemon juice/zest, then cream.
  8. Frost cooled cakes and serve. Optional: garnish with extra zest or berries.
