Ingredients

  • 3/4 cup fresh blueberries, raspberries or diced strawberries
  • 1 3/4 cups all-purpose flour
  • 2/3 cup granulated sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon fine salt
  • 2 large eggs
  • 1 cup milk
  • 1 stick (4 ounces) unsalted butter, melted
  • 1/2 teaspoon pure vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 cup light brown sugar
  • 4 tablespoons unsalted butter, softened

Method

  • For the muffins: Line a 12-cup muffin tin with foil muffin cup liners.
  • Toss the berries with 2 tablespoons of the flour in a small bowl.
  • Whisk the remaining flour, granulated sugar, baking powder and salt in a large bowl.
  • Beat the eggs in a medium bowl until frothy, and then whisk in the milk, melted butter and vanilla.
  • Make a well in the dry ingredients and pour the wet ingredients into the well.
  • Stir the batter with a rubber spatula until just combined.
  • For the topping: Combine the flour and brown sugar in a medium bowl.
  • Either using a fork or your fingers, mix in the butter to form large and medium crumbs.
  • Scoop the batter into the muffin cups, filling just above three-quarters full.
  • Divide the blueberries among the cups.
  • Divide the topping among the muffins, pressing lightly.
  • Freeze until set, about 3 hours.
  • The muffins can be removed to zippered freezer bags at this point and stored for up to 2 months.
  • When ready to bake, preheat the oven to 325 degrees F. Place the muffins in a muffin tin or directly on a baking sheet and bake until they are lightly golden and a tester inserted in the center comes out clean, 35 to 40 minutes.
  • These muffins can also be baked immediately.
  • Preheat the oven to 350 degrees F, and bake until lightly golden and a tester inserted in the center comes out clean, 20 to 25 minutes.
