Preheat the oven to 350℉/176℃. Line two baking trays with parchment paper and set aside. Peel and chop the apples into small cubes and set aside.
1 1/2 cups apples
Brown the butter. Melt the butter in a medium sized pan over medium heat. Once it melts, it will crackle, then become foamy – continue mixing the butter while this happens to prevent burning. The butter will go from melted to golden brown quickly, and you’ll know it’s almost done when the aroma of browned butter arrives. The whole process should take about 5 minutes! Once golden, remove from heat and transfer to a glass bowl. Let the butter cool for 15-30 minutes while you prep on the rest of the recipe.
1 cup + 1 tbsp unsalted butter
In a bowl, add the flour, oats, baking soda, baking powder, cinnamon, cornstarch, cloves, and salt. Stir to combine and set aside.
2 cups all-purpose flour, 2 cups rolled oats, 1 tsp baking soda, 1/2 tsp baking powder, 2 tsp cornstarch, 1/2 tsp salt, 1 tsp cinnamon, pinch of cloves
In another large bowl, add the brown butter (it can be warm, but not hot), white sugar, and brown sugar. Whisk to combine (1-2 minutes).
1/2 cup dark brown sugar, 1/2 cup white sugar, 1 cup + 1 tbsp unsalted butter
Whisk in the eggs and vanilla for another minute or so until well combined, scraping the sides of the bowl as needed.
1 tbsp vanilla, 2 large eggs
Add the dry ingredients in, and with a spatula gently fold until a soft cookie dough forms. Do not over-mix!
Mix in the chopped apples a few times to evenly distribute them in the cookie dough.
1 1/2 cups apples
Scoop and bake 6 cookies at a time. I used a 2 tbsp cookie scooper. The cookies will bake for 13-15 minutes and are ready when the edges are a golden brown color.
To make the glaze, combine powdered sugar, cinnamon, and milk until desired consistency is made. Drizzle, allow to set, and enjoy!
1 cup icing sugar, 2-3 tsp milk, Dash of cinnamon
