How to Make Crumbl Iced Oatmeal Cookies

- Preheat oven
Begin by preheating your oven to 350°F (175°C). This is key to ensuring your cookies bake evenly and achieve that perfect golden brown color. - Cream butter and sugars
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until fully combined and fluffy. This should take about 2-3 minutes for a nice airy texture. - Add egg and vanilla
Mix in the egg and vanilla extract until the mixture is light and airy. This will add moisture and help bind your cookie dough together beautifully. - Combine dry ingredients
Gradually add in the all-purpose flour, old-fashioned rolled oats, cinnamon, nutmeg, baking soda, and salt. Make sure to scrape down the sides of the bowl for an even mixture—that's where all the flavor hides! - Shape the cookies
Scoop out 8 equal cookie dough balls, gently flattening each to about 1 inch thick. Place them on the lined baking sheet, leaving space between each cookie to allow for spreading. - Bake cookies
Bake in your preheated oven for about 10 minutes. Keep an eye on them; they should look soft and gooey in the center to ensure that chewy texture you love. - Cool cookies
After baking, cool the cookies on the baking sheet for 20 minutes. This step allows them to firm up a bit before transferring them to a cooling rack. - Prepare the glaze
For the icing, whisk together the powdered sugar, milk, and vanilla until smooth. Adjust the consistency with a splash more milk if it's too thick; you want it to be pourable yet creamy. - Glaze the cookies
Dip the tops of the cooled cookies into the glaze, then return them to the cooling rack. Allow the glaze to set for a little bit before indulging in these delicious treats.
Optional: Enjoy with a glass of milk for a classic pairing!

Storage Tips for Best Crumbl Iced Oatmeal Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 4 days to maintain their chewy texture and delicious flavor.
Fridge: If you prefer, you can refrigerate the cookies for up to a week, which helps keep them fresh and extends their shelf life.
Freezer: For long-term storage, freeze iced cookies in an airtight container for up to 2 months. Thaw in the fridge or at room temperature before enjoying for the best results.
Reheating: If you want to warm them up, pop the cookies in a microwave for about 10-15 seconds. This will refresh the chewiness while keeping the glaze intact!
Make Ahead Options

These Crumbl Iced Oatmeal Cookies are perfect for busy home cooks looking to save time! You can prepare the cookie dough up to 24 hours in advance; just scoop and shape the dough balls, then wrap them tightly in plastic wrap or place them in an airtight container. For best results, chill the dough in the refrigerator to maintain freshness. When you're ready to bake, simply pop the dough straight from the fridge into the preheated oven, adding a couple of extra minutes to the baking time to ensure they are perfectly baked. The icing can also be made ahead; store it in a sealed container in the fridge for up to 3 days—just give it a good whisk before glazing the cookies for that delightful finish! Enjoy homemade treats with minimal stress!
Iced Oatmeal Cookies Variations
Feel free to let your creativity shine while making these delicious cookies! Each variation offers a new twist that enhances the warmth and flavor.
- Chocolate Chip: Swap out some oats for semi-sweet chocolate chips for a delightful chocolatey surprise in every bite. A little cocoa goodness never hurt anyone!
- Nutty Crunch: Add in chopped walnuts or pecans to the dough. They'll add a satisfying crunch and an earthy richness that beautifully complements the sweetness.
- Dried Fruits: Mix in dried cranberries, raisins, or apricots for a burst of fruity flavor. The chewy fruit will elevate the cookies with a bit of tanginess.
- Spiced Twist: Include a dash of cardamom or ginger in addition to cinnamon for an exotic flavor boost. This adds warmth and depth—perfect for chilly days!
- Vegan Option: Replace the egg with a flax egg (1 tablespoon ground flaxseed + 2.5 tablespoons water) and use coconut oil instead of butter for a plant-based treat.
- Frosting Flavors: Change up the icing by adding flavored extracts like maple or almond. It’s a simple way to give your cookies a personalized touch and surprise everyone!
- Pumpkin Spice: During fall, add in a bit of pumpkin puree (up to ½ cup) to the dough along with extra oats. This creates a seasonal delight that's irresistibly moist and flavorful.
- Salted Caramel Drizzle: Drizzle some homemade or store-bought caramel sauce over the glazed cookies finished with a sprinkle of sea salt. The contrast of sweet and salty is heavenly!
Expert Tips for Crumbl Iced Oatmeal Cookies
• Softened Butter: Ensure butter is softened but not melted. Using melted butter can lead to overly greasy dough, resulting in cookies that spread too thin.
• Measure Flour Properly: Spoon flour into your measuring cup rather than scooping it directly from the bag. This prevents the dough from becoming too dense and ensures that you create the best Crumbl iced oatmeal cookies.
• Don’t Overbake: Keep an eye on your cookies; they should look soft and gooey in the center when you take them out of the oven. Overbaking can result in dry cookies instead of the chewy texture you desire.
• Adjust Glaze Consistency: If your icing is too thick, cool it in the fridge for 10–15 minutes before using. This makes it easier to dip without running off the sides.
• Experiment with Mix-Ins: Feel free to get creative! Adding dark chocolate chunks or nuts can elevate these cookies further, making them uniquely yours while maintaining that classic oatmeal flavor.
• Storage Tips: Keep your cookies in an airtight container for up to 4 days at room temperature. They also freeze well for up to 2 months, making them a perfect make-ahead treat!

The Best Crumbl Iced Oatmeal Cookies Recipe FAQs

How do I select the best oats for my cookies?
Absolutely! For the best texture, I recommend using old-fashioned whole rolled oats, as they provide a hearty chew. Quick oats can be used but may alter the texture slightly, leading to a softer cookie. Look for oats that are whole and have a good aroma; they should not smell stale.
How should I store my iced oatmeal cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to 4 days. If you prefer, you can refrigerate them for up to a week. Just remember to let them come back to room temperature for the best taste!
Can I freeze the cookies, and if so, how?
Yes, these cookies freeze wonderfully! To freeze, first ensure the glaze is set. Then, place the cookies in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe airtight container or zip-top bag. They can last in the freezer for up to 2 months. To thaw, simply leave them at room temperature or in the fridge overnight before enjoying.
What if my icing is too thick?
If your icing is too thick to dip, don’t worry! Just add a tiny bit of milk, a teaspoon at a time, until you achieve the desired consistency. It should be pourable yet thick enough to coat the cookie tops nicely. If it becomes too runny, chill it in the fridge for about 10-15 minutes to thicken it up.
Are these cookies suitable for gluten-free diets?
Absolutely! You can easily modify this recipe to be gluten-free by substituting the all-purpose flour with a gluten-free blend. Make sure that your oats are certified gluten-free as well, as cross-contamination can sometimes occur. Enjoy baking without worry!
Can I make these cookies vegan?
Very! To make them vegan, simply replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let it sit for 5 minutes to thicken) and use a dairy-free alternative for both the butter and milk in the icing. This way, everyone can enjoy these delightful cookies!
