Method
Prepare the pans
- Preheat the oven to 350°F.
- Line two large baking sheets with parchment paper.
Make the cookie dough
- In a large bowl, beat 1/2 cup softened butter and the granulated sugar with an electric mixer on medium speed for 2 to 3 minutes, until light and fluffy.
- Beat in the egg and vanilla until combined.
- In a medium bowl, whisk 1 1/2 cups flour, the baking powder, baking soda, and salt.
- Add the flour mixture to the butter mixture and mix on low just until no dry flour remains.
Make the streusel
- In a small bowl, stir together the remaining 1/2 cup flour, brown sugar, and cinnamon.
- Stir in 1/4 cup melted butter until coarse crumbs form.
Shape and bake
- Scoop the dough into 20 portions, about 2 tablespoons each.
- Place 10 portions on each baking sheet, spacing them about 2 inches apart.
- Make a shallow indent in each portion.
- Press streusel into each indent.
- Bake for 11 to 13 minutes, switching the sheets’ rack positions and rotating them halfway through, until the edges are lightly golden and the centers look set.
- Cool the cookies on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack and cool completely.
Make the glaze
- Whisk the powdered sugar and milk until smooth.
- Drizzle the glaze over the cooled cookies.
- Let the glaze set for about 10 minutes before serving.
Notes
For tender cookies, mix the flour in just until no dry flour remains. Store airtight in the refrigerator for up to 5 days; freeze for up to 2 months. For a dairy-free option, use dairy-free butter and plant-based milk.
