Ingredients

cooking spray
1/2 cup all-purpose flour
1/4 cup brown sugar
1/2 teaspoon ground cinnamon
1/4 teaspoon salt
1/4 cup butter, softened
2 cups all-purpose flour
3 teaspoons baking powder
1 teaspoon cinnamon
1/4 teaspoon salt
2 large eggs
1/2 cup granulated sugar
1/2 cup brown sugar
1 cup sour cream
1/2 cup vegetable oil
1 teaspoon vanilla extract
2 cups blueberries
1 tablespoon all-purpose flour

Directions

1 Preheat the oven to 400 degrees F (200 degrees C). Grease 16 muffin cups with cooking spray or line with paper liners.
2 Make topping: Combine flour, brown sugar, cinnamon, and salt in a small bowl. Cut butter into flour mixture with 2 knives or a pastry blender until crumbly. Set topping aside.
3 Make muffins: Whisk together 2 cups flour, baking powder, cinnamon, and salt in a large bowl, making a well in the center. Whisk together eggs, granulated sugar, and brown sugar in a separate bowl. Stir in sour cream, oil, and vanilla until well combined. Pour into well and stir until batter is just combined without overmixing. Toss blueberries with 1 tablespoon flour in a small bowl and gently fold into batter.
4 Spoon batter into the prepared muffin cups, filling each 3/4 full. Sprinkle each muffin with about 1 tablespoon topping.
5 Bake in the preheated oven until tops spring back when lightly pressed and muffins are lightly browned, 18 to 22 minutes. A toothpick inserted into the center of muffins should come out clean. Cool in the pan for 10 minutes. Transfer to a wire rack to cool completely.
