# What you'll need:

→ Cookie Dough

01 - 1 1/2 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/4 teaspoon baking soda
04 - 1/4 teaspoon salt
05 - 1/2 cup unsalted butter, softened
06 - 2/3 cup granulated sugar
07 - 1 large egg
08 - 1 teaspoon vanilla extract
09 - 1/4 cup whole milk
10 - 1 cup fresh or frozen blueberries

→ Streusel Topping

11 - 1/3 cup all-purpose flour
12 - 1/4 cup light brown sugar, packed
13 - 1/2 teaspoon ground cinnamon
14 - 3 tablespoons unsalted butter, cold and cubed

# How to make it:

01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a small bowl, mix flour, brown sugar, and cinnamon. Add cold butter and rub together with fingers or fork until mixture is crumbly. Set aside.
03 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well blended.
04 - In a large bowl, beat softened butter and granulated sugar until light and fluffy, approximately 2-3 minutes.
05 - Beat in the egg and vanilla extract until fully incorporated into the butter mixture.
06 - Add dry ingredients to butter mixture in two additions, alternating with milk. Mix until just incorporated, being careful not to overmix.
07 - Gently fold blueberries into the batter until evenly distributed. If using frozen berries, add directly from freezer without thawing.
08 - Scoop approximately 2 tablespoons of dough per cookie onto prepared baking sheets, spacing cookies 2 inches apart.
09 - Sprinkle each cookie mound generously with prepared streusel topping, pressing lightly to adhere.
10 - Bake for 13-15 minutes until edges are set and tops are lightly golden brown.
11 - Let cookies cool on baking sheet for 5 minutes before transferring to wire rack to cool completely.

# Expert Tips:

01 -
  • They taste like a muffin but have the irresistible texture of a soft cookie
  • The streusel topping adds buttery cinnamon crunch that makes them feel special
  • Fresh blueberries burst in every bite creating little pockets of sweetness
02 -
  • Overmixing the dough will make these tough so stop as soon as the flour streaks disappear
  • Frozen blueberries can turn your dough purple if you thaw them first so add them straight from the freezer
  • The streusel needs cold butter to stay crumbly so work quickly and keep it chilled until you use it
03 -
  • Use a cookie scoop for uniform cookies that bake evenly
  • Room temperature ingredients blend better and create a tender crumb
