• 1/2 cup butter (softened)
• 1/3 cup brown sugar
• 1/4 cup granulated sugar
• 1 tbsp vanilla extract
• 1 egg (at room temperature)
• 1 & 1/4 cup old fashioned whole rolled oats
• 1 cup AP flour

• 3/4 cup powdered sugar
• 1.5 tbsp milk
• 1/4 tsp vanilla

Pro Tips

For truly exceptional Crumbl Iced Oatmeal Cookies, these three techniques make all the difference:

First, don’t rush the creaming process. Spending a full 3-4 minutes creaming the butter and sugars until light and fluffy creates air pockets that give your cookies the perfect texture. This step is crucial for cookies that are soft in the center with slightly crisp edges.

Second, measure your flour correctly by spooning it into your measuring cup and leveling it off with a knife. Scooping directly with the measuring cup compacts the flour, potentially leading to dry, dense cookies. This simple technique ensures you get the right flour-to-moisture ratio every time.

Finally, for that authentic Crumbl appearance, apply the icing when the cookies are still slightly warm but not hot. This creates a beautiful, slightly translucent layer that sets with a shiny finish. If you ice them when completely cool, you’ll get a more opaque white topping, which is still delicious but offers a different aesthetic.

Instructions

Step 1: Preheat the oven to 350F then line a baking sheet with parchement paper and set aside.

Step 2: Cream the butter brown sugar, and granulated sugar together until combined. Add in the egg and vanilla and mix until light and fluffy.

Step 3: Mix in the flour, oats, cinnamon, nutmeg, baking soda, and salt, making sure to scrape the sides until the mixture is combined.

Step 4: Using a large cookie scooper, scoop out 8 equally sized cookie dough balls, place them on the prepared baking sheet, gently press down on the cookies to about 1 inch in thickness, and bake them in the preheated oven for 10 minutes. Make sure to not overbake them so they stay soft and gooey.

Step 5: Let the cookies cool down on the baking sheet for 20 minutes then more to a cooling rack to cool down fully.

Step 6: While the cookies are cooling, prepare the icing by whisking together the powdered sugar, milk, and vanilla until smooth.

Step 7: Once cookies are cooled, drizzle or spread the icing over each cookie, allowing it to set for about 30 minutes before serving.

Variations

The classic Crumbl Iced Oatmeal Cookies recipe is divine on its own, but these variations can add exciting twists:

For a fruit-forward version, fold in 1/2 cup of dried cranberries or raisins to the dough before baking. This adds chewy texture and tangy sweetness that complements the warm spices beautifully. The dried fruit plumps slightly during baking, creating pockets of concentrated flavor.

For a gluten-free adaptation that doesn’t sacrifice texture, substitute the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend. Since oats are naturally gluten-free (though be sure to use certified gluten-free oats for those with celiac disease), this substitution works particularly well in oatmeal cookies.

For a fall-inspired twist, increase the cinnamon to 1/2 teaspoon, add 1/4 teaspoon of ground ginger, and fold in 1/3 cup of finely chopped crystallized ginger. This creates a spicier cookie with pleasant heat that pairs perfectly with coffee or tea.

Storage and Serving

These Crumbl Iced Oatmeal Cookies stay fresh when stored in an airtight container at room temperature for up to 5 days. Place parchment paper between layers if stacking to prevent the icing from sticking. For longer storage, you can freeze the uniced cookies for up to 3 months; simply thaw at room temperature and add fresh icing before serving.

For an elevated dessert experience, sandwich a scoop of vanilla ice cream between two cookies to create the ultimate ice cream sandwich. The contrast between the cold ice cream and soft, spiced cookies creates a memorable treat.

Serve these cookies slightly warmed (10 seconds in the microwave) alongside a steaming cup of cinnamon tea or coffee for a cozy afternoon snack. The warmth reactivates the spices and softens the cookies just enough to make them extra comforting.

For a special touch when entertaining, stack them on a vintage cake stand and dust with a tiny sprinkle of cinnamon for visual appeal and an aromatic boost.

FAQs

Can I use quick oats instead of old-fashioned oats?
While quick oats will technically work, they’ll give your Crumbl Iced Oatmeal Cookies a different texture. Old-fashioned oats provide that signature chew and hearty texture that makes these cookies special. Quick oats will make a softer, less textured cookie.

Why did my icing harden too quickly?
If your icing hardened before you could spread it, you likely used too little milk. Add 1/4 teaspoon more milk at a time until you reach a consistency that’s thick but spreadable.

Can I make the cookie dough ahead of time?
Yes! The cookie dough can be refrigerated for up to 3 days before baking. Let it come to room temperature for about 30 minutes before scooping and baking for the best texture.

My cookies spread too much during baking. What went wrong?
This typically happens if your butter was too warm or melted. Make sure it’s softened but still cool to the touch. Refrigerating the dough for 30 minutes before baking can also help prevent excessive spreading.

How do I know when the cookies are done?
The cookies should look slightly underdone in the center when you remove them from the oven. The edges should be set and just barely starting to turn golden. They’ll continue cooking on the hot baking sheet after removal from the oven, resulting in that perfect soft center.

These Crumbl Iced Oatmeal Cookies bring together the comfort of traditional oatmeal cookies with the bakery-style presentation that Crumbl is famous for. With their soft centers, perfectly balanced spices, and sweet icing topping, they’re sure to become a regular in your baking rotation.
