Preheat the oven to 350 degrees Fahrenheit.
Whisk together all wet ingredients in a mixing bowl.
Fold in the dry ingredients, making sure to spoon and level the flours.
When a dough has formed, fold in the blueberries. Try not to mash them too much, I do like to mash a few because it gives the cookies a slightly marbley look which is pretty!
Use a medium cookie scoop (2 tablespoons) and scoop into balls. Place on a baking sheet lined with parchment paper. Bake one cookie sheet at a time for 12-16 minutes. I usually do 14-15, but all ovens are different. These don't crisp up as much as a typical cookie, but the bottoms/edges should be golden brown when you take them out of the oven.
Whisk together the ingredients for the glaze, then drizzle on top when the cookies have cooled. Enjoy!
