How to Make Iced Oatmeal Cookies – Crumbl Copycat Recipe
Step 1: Prepare Your Oven and Baking Sheet
Start by preheating your oven to 350°F (175°C) to ensure a perfectly even bake. Line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze, setting yourself up for success right from the start.
Step 2: Cream Butter and Sugars
In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light, fluffy, and well combined. This step is crucial for creating a tender, airy cookie. Then add the egg and vanilla extract, mixing until everything is fully incorporated and smooth.
Step 3: Mix Dry Ingredients and Combine
Next, stir together the all-purpose flour, rolled oats, cinnamon, nutmeg, baking soda, and salt in a separate bowl. Gradually add this to the wet ingredients, folding them gently until just combined. Overmixing can make cookies tough, so stop once the dough comes together with beautiful specks of oats and spice.
Step 4: Scoop and Bake the Cookies
Using a cookie scoop or spoon, drop rounded portions of dough onto the prepared baking sheet, spacing them apart. Flatten each slightly with your palm or the back of a spoon to promote even cooking. Bake for about 10 minutes or until the edges set but the centers remain soft and tender—this is key to that perfect chewy texture.
Step 5: Cool and Glaze Your Cookies
Allow the cookies to cool on the baking sheet for about 20 minutes; this helps them firm up without losing that lovely softness. While cooling, whisk together powdered sugar, milk, and vanilla to create a smooth glaze. Drizzle this icing over the tops of the cookies for that iconic look and sweet finishing touch of the Iced Oatmeal Cookies – Crumbl Copycat Recipe.
How to Serve Iced Oatmeal Cookies – Crumbl Copycat Recipe

Garnishes
For an extra special presentation, consider sprinkling a bit of cinnamon or finely chopped toasted nuts on top of the icing just before it sets. This adds a rustic flair and a hint of crunch that pairs beautifully with the soft cookie base.
Side Dishes
These cookies shine when paired with a cold glass of milk or a warm cup of chai tea. The spices in the cookie complement the comforting notes in your favorite tea or coffee, making every bite feel like a cozy celebration.
Creative Ways to Present
For gatherings or gift-giving, stack these iced oatmeal cookies in a clear jar with ribbons, or serve them on a decorated platter with small bowls of extra glaze for dipping. You can even sandwich two cookies together with a layer of cream cheese frosting for a delightful variation.
Make Ahead and Storage
Storing Leftovers
Store any leftover iced oatmeal cookies in an airtight container at room temperature for up to 3 days to keep them soft and flavorful. If you want to extend freshness, placing a small piece of bread inside the container helps maintain moisture.
Freezing
These cookies freeze wonderfully. Place them in a single layer on a baking sheet until firm, then transfer to a freezer-safe container. They’ll keep for up to 3 months. When ready to enjoy, thaw them at room temperature and refresh the icing if needed.
Reheating
Warm leftover cookies in a microwave for about 10-15 seconds or in a low oven at 300°F (150°C) for 5 minutes. This brings back that fresh-baked feeling, making the icing slightly melty and the oats wonderfully chewy again.
FAQs
Can I substitute the butter with margarine or oil?
While you can use margarine in a pinch, butter gives the best flavor and texture. Oils typically don’t work well in this recipe because they alter the dough’s consistency and the final chewiness.
What type of oats should I use?
Old-fashioned rolled oats are ideal for this recipe since they provide a nice texture without making the cookies too dense, unlike steel-cut or instant oats.
Can I make the icing thicker or thinner?
Yes! Simply add more powdered sugar to thicken or a few more drops of milk to thin the glaze until you reach your desired consistency.
Are these cookies gluten-free?
This recipe calls for all-purpose flour, so it’s not gluten-free as is. However, if you use a high-quality gluten-free flour blend, you can create a gluten-free version with similar results.
How long will the icing remain fresh on the cookies?
The icing will stay fresh for about 1-2 days at room temperature before it starts to lose its sheen and slightly dry out, so enjoy the cookies soon after glazing for the best experience.
