The oatmeal gives these cookies a heartiness that is perfect this time of year. And with little pieces of apple throughout the cookie, every bite is a treat.

I used the icing to add a little bit more flavor to these cookies. Just like cinnamon apple donuts have nutmeg, I added a dash of nutmeg to the icing. It gives it a warm, spiced flavor that reminds me of Fall!

I’m a big fan of using vanilla bean paste in recipes, but if you don’t have any on hand, you can absolutely use vanilla extract instead, in both the cookies and the icing. The flavor will be slightly different. Vanilla bean paste has a deeper, more intense vanilla flavor.

Now that we’ve covered the vanilla bean paste, we need to talk about storage. Most cookies can be frozen without any issues. But because these cookies are made with fresh apple pieces, I don’t recommend freezing the baked cookies. The moisture from the apples can cause the cookies to soften quite a bit as they thaw, changing that lovely soft and chewy texture.

However, the good news is that you can easily freeze the unbaked cookie dough instead. Scoop the dough into portions, freeze the dough balls on a parchment-lined plate or tray, and then transfer them to freezer bags once they’re completely frozen. When the cookie craving strikes, you can bake them straight from the freezer. Just place the frozen dough on a parchment-lined baking sheet and add about 1 to 2 minutes to the baking time.

Once the cookies are completely cool, combine the powdered sugar, salt, nutmeg, vanilla, and 1 tablespoon of milk in a small bowl and whisk vigorously until smooth. If the icing is too thick, add more milk, a splash at a time, until it reaches a drizzleable consistency.

It should be thin enough to drizzle but thick enough to hold its shape on top of the cookies. 

Drizzle the icing over the cookies with a spoon. Enjoy immediately, or allow the glaze to set for about 30–45 minutes.

How to Store

Leftovers can be stored at room temperature in an airtight container for up to 2 days, or in the refrigerator for up to 1 week.

Notes

Recipe Notes

  • Any firm apple can be used in place of the Granny Smith such as Pink Lady, Honeycrisp, or Cosmic Crisp. You’ll need 1 medium apple in order to yield 1 cup of finely chopped apple.
  • Recipe Tips and Testing Notes

    • Be sure to use old-fashioned rolled oats instead of quick-cooking oats. Quick-cooking oats absorb more moisture during baking, resulting in a softer texture rather than a chewy one.
    • I personally love the tartness of a Granny Smith apple in these cookies because it pairs well with the sweetness of the cookies and the icing. Feel free to use any firm apple variety here that will hold its shape during baking. 
    • The nutmeg in the icing adds extra depth to the warm spice of the cinnamon. Freshly grated nutmeg offers the best flavor, but you can swap in additional cinnamon if you do not have nutmeg on hand.
    • These cookies have the best texture on the day they’re made since the pieces of apple and the icing will release moisture into the cookies over time. Their texture becomes softer and less chewy, but they’re still delicious! 
    • The chewy texture of these cookies relies on the combination of the old fashioned oats, the extra egg yolk, the brown sugar, and baking them until they are just set. 

    FAQs

    Can I use vanilla extract instead of vanilla bean paste? Yes, you can swap vanilla extract for the vanilla bean paste in the cookies and the icing. The cookies' flavor will vary slightly, as vanilla bean paste has a deeper, more intense flavor. 

    Can I freeze these cookies? Freezing the baked cookies is not recommended, as their texture softens significantly as they thaw due to the apple pieces. However, you can easily freeze balls of unbaked dough and bake them straight from the freezer. Use a scoop to portion the dough, freeze the portions on a parchment-lined plate or tray, and then transfer them to freezer bags once fully frozen. When you are ready to bake, place the frozen dough balls onto a parchment-lined sheet and bake according to the recipe instructions, adding 1–2 minutes to the total baking time.
