These coffee cake cookies combine a soft, buttery cookie with a crumbly streusel filling and a sweet glaze, bringing the flavors of classic coffee cake into a delicious bite-sized treat!
Using an electric mixer on medium speed, beat the butter and both sugars in a large mixing bowl until fluffy. Beat in the egg and vanilla until smooth.
With the mixer on low speed, add the flour, baking powder, and salt, and mix just until combined.
Chill the dough for at least one hour or up to 24 hours.
To make the streusel and assemble the cookies:
In a small mixing bowl, whisk together the brown sugar, flour, cinnamon, and melted butter. The mixture should look crumbly.
Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper or silicone liners.
Scoop the dough using a #40 cookie scoop (about 1 & 1/2 tablespoons), and roll into balls. Place the dough balls about two inches apart on the baking sheets.
Use the bottom of a rounded tablespoon to make a well in the middle of each cookie dough ball and then fill it with streusel. Dip the measuring spoon in a bit of flour to help prevent sticking.
Bake one pan at a time for 10 minutes or until the edges are light golden brown and the cookies appear set.
Allow the cookies to cool on the pans on a wire rack for 5 minutes, and then transfer them from the pans directly onto a wire rack to cool completely.
To make the glaze:
In a small bowl, whisk together the confectioners' sugar and 2 tablespoons of the milk. Add small amounts of the remaining milk if needed to reach the desired glaze consistency.
Drizzle the glaze over the cooled cookies and allow to set before serving.
