Instructions

• 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 ½ teaspoon salt. Set aside.
• In a medium bowl, whisk eggs until smooth. Add the ½ 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 ¼ cup flour, 2 tablespoons brown sugar, 2 tablespoons granulated sugar, cinnamon, and ⅛ 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.
