Ingredients

  • For the Cookies:
    • ½ cup unsalted butter, softened
    • ½ cup granulated sugar
    • ¼ cup brown sugar
    • 1 large egg
    • 1 teaspoon vanilla extract
    • 1½ cups all-purpose flour
    • 1 teaspoon baking powder
    • ½ teaspoon baking soda
    • ¼ teaspoon salt
    • 1 cup fresh or frozen blueberries
  • For the Streusel Topping:
    • ¼ cup granulated sugar
    • 2 tablespoons all-purpose flour
    • 2 tablespoons unsalted butter, cold and cubed

Instructions

  1. Preheat Oven: Preheat to 375°F (190°C) and line a baking sheet with parchment paper.
  2. Make Streusel: In a small bowl, mix sugar and flour. Cut in cold butter until crumbly. Chill in the fridge while preparing dough.
  3. Cream Butter and Sugars: In a large bowl, beat butter, granulated sugar, and brown sugar until fluffy. Add egg and vanilla; mix until smooth.
  4. Combine Dry Ingredients: In a separate bowl, whisk flour, baking powder, baking soda, and salt. Gradually mix into wet ingredients until just combined.
  5. Fold in Blueberries: Gently fold in blueberries, especially if using frozen, to prevent excess bleeding.
  6. Shape Cookies: Drop rounded tablespoons of dough onto the prepared baking sheet. Flatten each slightly.
  7. Add Streusel: Sprinkle chilled streusel topping over each cookie, pressing lightly so it sticks.
  8. Bake: Bake for 12–15 minutes, until edges are golden. Cool on the pan for 5 minutes, then transfer to a wire rack.

Notes

  • Use cold butter for the streusel to keep it crisp.
  • Frozen blueberries work well—add straight from the freezer.
  • For extra flavor, add lemon zest or cinnamon to the dough or streusel.
  • Don’t overmix to maintain a tender, muffin-like crumb.
