Ingredients

• 0.5 cups butter
• 0.5 cups white sugar
• 2 large eggs
• 0.5 cups sour cream
• 1 teaspoon vanilla extract

Instructions

1. 1 Preheat the oven to 325 degrees F (165 degrees C). Grease an 8x4-inch loaf pan.
2. 2 Beat butter and sugar with an electric mixer in a large bowl until fluffy and lighter in color. Add eggs one at a time, beating well after each addition. Beat in sour cream, vanilla, and lemon zest; beat for 2 minutes. Combine flour, cornstarch, salt, and baking soda in a separate bowl. Add flour mixture to butter mixture, beating until just incorporated. Pour batter into the prepared pan.
