These Coffee Cake Cookies are made with a chewy, cinnamon cookie base, topped with a buttery oat streusel, and drizzled with glaze. They’re everything you love about coffee cake, baked into a soft, glazed cookie.
Preheat the oven to 375 degrees F and line 2 or 3 baking sheets with parchment paper.
With an electric mixer, cream together butter, sugars and sour cream on medium speed.
Add in the eggs and vanilla extract and beat until smooth.
Then add flour, corn starch, cinnamon, salt, baking powder and baking soda and beat on low speed until combined.
Roll the cookie dough into balls (1-2″ rounds -- I use a size 24 cookie scoop or roughly 2.5 tablespoons) and place 2″ apart on prepared baking sheet.
Streusel
Combine butter, brown sugar, granulated sugar, cinnamon, flour and oats with a pastry cutter (or your fingers!) until crumbly.
Press some streusel into the top of every cookie -- try to get as much on and around the sides as you can (the bottom isn't necessary).
Bake for 9-12 minutes, depending on how large you made them. Bake until lightly golden throughout. They will continue to set as they cool. Don't overbake!
Let the cookies cool on the baking sheet for a couple of minutes before glazing.
Glaze
Whisk together powdered sugar and milk until smooth. Drizzle over cookies and allow a couple minutes to set. Serve.

Notes
Ingredients and Substitutions:Flour: you can swap half of the flour for whole wheat flour for a heartier cookie.Cinnamon: Feel free to increase the cinnamon or add in a pinch of other warm spices, such as nutmeg, ginger or cloves.Glaze: you can swap the milk for maple syrup to make a maple glaze.Storage:Allow glaze to set completely before storing. These cookies can be stored at room temperature in an airtight container for up to 4 days, or frozen for up to 3 months. I recommend layering with parchment paper if freezing.
