Blueberry Muffins

Preheat oven to 400 degrees. Prepare a muffin pan with cupcake liners. In a large bowl, sift together 2 cups flour, 1 cup sugar, baking powder, and 1/2 teaspoon salt. Set aside.

In a medium bowl, whisk eggs until smooth. Add the 1/2 cup melted butter, milk, and vanilla, and whisk until combined. Add egg mixture to flour mixture and stir until combined. (Dough will be lumpy.) Fold in blueberries.

To prepare the streusel topping, in a medium bowl combine 1/4 cup flour, 2 tablespoons brown sugar, 2 tablespoons granulated sugar, cinnamon, and 1/8 teaspoon salt. Using a pastry cutter, cut in butter until topping is crumbly and coarse.

Fill prepared muffin cups with batter. Top each muffin with streusel topping, about 1 tablespoon each. Bake until a toothpick inserted in the center of a muffin comes out clean with a few crumbs attached, about 18 to 22 minutes. Cool muffins on a rack for several minutes before removing from pan. Cool completely and store in an airtight container, up to 4 days.
