Equipment

  • jumbo muffin tin

Ingredients

Muffin Batter

  • ⅓ cup vegetable oil
  • ⅓ cup milk
  • 1 egg
  • 1½ cups all purpose flour
  • ¾ cup white sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 1½-2 cups blueberries

Streusel Topping

  • ⅓ cup all-purpose flour
  • ¼ cup butter cubed
  • ½ cup white sugar
  • 1½ teaspoons cinnamon

Instructions

  • Prep. Preheat the oven to 400 degrees with the rack in the center. Line a muffin tin with cupcake liners.
  • Make batter. Combine the wet ingredients (melted butter, egg, and milk in one bowl. In a separate bowl, combine the dry ingredients (flour, sugar, salt, baking powder). Gently mix them together, stirring until just combined. Fold in the blueberries.
  • Make streusel topping. Cut the butter into the flour in a medium mixing bowl, using two knives or a pastry blender, until it resembles small peas. Stir in the sugar and cinnamon.
  • Assemble. Scoop the batter into the prepared muffin tins. Equally distribute the topping on top of the muffin batter.
  • Bake. Bake for 25-30 minutes (20-25 minutes for regular-sized muffins). Remove from oven when a toothpick served into the center comes out clean or with a few crumbs. Remove to a wire rack to cool. Serve warm or at room temperature.

Notes

You can use melted butter instead of oil, but I find oil easier to work with and yields a moister muffin.
You can also make these into 1 dozen regular-sized muffins.  You won't need to alter the batter or topping in any way, but reduce the baking time to about 20 minutes.
Serve with a hearty main course like this fresh asparagus quiche for the perfect brunch.
