Ingredients
Method
Preparation
- Preheat the oven to 350°F (175°C) and grease and flour a 9x13 inch baking dish.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this aside.
Mixing
- In a large mixing bowl, beat the softened butter and sugar together until light and fluffy, about 3-4 minutes.
- Beat in the eggs one at a time, followed by the vanilla extract, ensuring everything combines well.
- Mix in the sour cream until smooth and creamy.
- Gradually add the flour mixture, mixing just until combined. Be careful not to overmix; it's okay if a few lumps remain!
- Gently fold in the fresh blueberries, being cautious not to break them apart.
Baking
- Spread the batter evenly in the prepared baking dish.
- Bake for approximately 45-50 minutes, or until a toothpick inserted in the center comes out clean.
Finishing Touches
- Let the cake cool for at least 15 minutes before dusting with powdered sugar, if desired.
Notes
Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat in the microwave for about 15-20 seconds.
