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.
