Preheat oven to 350 degrees.
Mix cookie ingredients in a large bowl until well combined. (Dough will be thick)
Scoop cookies onto a parchment-lined sheet.
Bake 7-8 minutes. Cool on sheet for 4-5 minutes before moving to a rack.
For glaze, cook all ingredients in a saucepan over medium-low heat, whisking constantly, until sugar dissolves (about 4 minutes).
Spoon a teaspoon of glaze over each cookie.
Let glaze set, then sprinkle with powdered sugar.
Store in an airtight container at room temperature for up to 3 days (if they last that long!).
Now go on and bake up a batch. Your taste buds will thank you!
