INGREDIENTS
TOPPING:
- 3/4 cups all-purpose flour 
- 3/4 cup granulated sugar 
- 1/4 teaspoon salt 
- 5 tablespoons unsalted butter — melted 
MUFFINS:
- 2 eggs

- 1 teaspoon baking soda 
- 1/2 teaspoon salt 
- 1 cup sour cream 
- 2 cups all purpose flour 
- 1 cup blueberries — wild or regular sized, fresh or frozen but defrosted and drained 
INSTRUCTIONS
- If you’re using frozen berries, make sure to let them defrost and drain well before adding them to the muffins. 
- Preheat oven to 350°F. Line muffin pans with paper baking cups. 
- Make the topping by stirring together all topping ingredients with a fork in a medium sized bowl. Set aside. 
- Using a hand mixer, mix eggs with electric mixer about 1-2 minutes until thick and frothy. Mix in sugar and oil, beat until creamy. Mix vanilla, vinegar, baking soda, and salt. Mix in sour cream then stir in flour using a wooden spoon. (Batter may be slightly lumpy.) Stir in blueberries. 
- Fill muffin cups with about 1/4 cup muffin batter. Sprinkle the crumble evenly over the top of the muffins. 
- Bake for 15-22 minutes until a toothpick comes out clean from the center of a muffin. Cool 5 minutes in pan then remove to a rack to cool completely. 
- Store in an airtight container for up to 3 days or freeze for up to one month.
