Notes on Quality

Step-by-Step Instructions

1. Preheat the oven to 350°F (180°C). Grease and flour a 9×13-inch pan. For layer cakes, line pans with parchment and grease the sides.
2. Mix dry ingredients.
   In a medium bowl sift together flour, baking powder, baking soda, and salt.
3. Combine liquids.
   Whisk the buttermilk and lemon juice together in a small bowl.
4. Cream butter and sugar.
   In a large bowl beat butter, sugar, and lemon zest until light and fluffy (about 2-3 minutes).
5. Add eggs and vanilla.
   Beat in the eggs one at a time, scraping the bowl after each addition. Mix in vanilla.
6. Alternate dry and wet ingredients.
   On low speed add about one-third of the flour mixture, followed by half the buttermilk mixture. Repeat and finish with the remaining flour mixture. Avoid overmixing.
7. Add blueberries.
   Toss blueberries with 2 teaspoons flour and gently fold them into the batter.
8. Transfer batter.
   Pour into prepared pan or cake tins.
9. Bake.
   Bake 30-35 minutes for a 9×13 cake or 25-30 minutes for layers. The top should be set and a toothpick should come out clean.
10. Cool completely before frosting.

Cream Cheese Frosting

1. Beat butter until soft and smooth.
2. Mix in the cream cheese until fully combined.
3. Add lemon juice and 3 cups powdered sugar.
4. Beat on low speed first, then increase to medium.
5. Add additional powdered sugar gradually until desired sweetness and thickness is reached.
6. If frosting becomes too thick, mix in a tablespoon of whipping cream.

Decorating

For a 9×13 Cake

Spread frosting evenly across the cooled cake. Decorate with fresh blueberries and thin lemon slices if desired.

For a Layer Cake

1. Ensure cake layers are completely cooled.
2. Trim domed tops if necessary.
3. Place the first layer on a serving plate and spread about ¾ cup frosting.
4. Add the second layer and repeat.
5. Place the final layer on top.
6. Apply a thin crumb coat and chill for 20-30 minutes.
7. Finish frosting the cake with decorative swirls.
8. Garnish with blueberries if desired.
