- 1/4 cup granulated sugar: Gives a light sweetness and helps with cookie structure.
- 1 tbsp vanilla extract: Enhances all the flavors with a warm, aromatic touch.

- 1 & 1/4 cups old-fashioned rolled oats: Brings wholesome chewiness and that classic oatmeal cookie charm.
- 1 cup all-purpose flour: The sturdy backbone that makes these cookies just right—not too cakey, not too dense.
- 1/4 tsp cinnamon: Infuses subtle warmth that’s irresistible.
- Pinch of nutmeg: Lends a gentle spiciness that rounds out the flavor profile.
- 1/2 tsp baking soda: Helps cookies rise slightly and gives a tender crumb.
- 1/4 tsp salt: Balances sweetness and enhances all the flavors.
- 3/4 cup powdered sugar: The base of the icing, adding smooth sweetness with every bite.

How to Make Iced Oatmeal Cookies – Crumbl Copycat Recipe
Step 1: Prepare your oven and baking sheet
First things first, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup and to prevent the cookies from sticking. Setting the perfect oven temperature ensures your cookies bake evenly with that soft texture we love.
Step 2: Cream the butter and sugars
In a mixing bowl, beat together the softened butter, brown sugar, and granulated sugar until the mixture is fluffy and light in color. This creaming process incorporates air which gives your cookies a soft lift. Then, add the egg and vanilla extract, mixing until everything is smoothly combined.
Step 3: Mix in the dry ingredients
Now, stir in the all-purpose flour, rolled oats, cinnamon, nutmeg, baking soda, and salt. Mix just until combined to avoid overworking the dough which can make cookies dense. You’ll notice the texture comes together into a dough that’s ready to be portioned.
Step 4: Scoop and bake
Use a cookie scoop or spoon to drop rounded dough balls onto the prepared baking sheet, spacing them a couple of inches apart. Gently flatten them slightly for even baking. Place in the oven and bake for about 10 minutes. The end goal is soft, not overbaked cookies with a slight golden edge.
Step 5: Cool and ice the cookies
Allow the cookies to cool on the baking sheet for around 20 minutes—that way they firm up without losing their softness. While they cool, whisk together powdered sugar, milk, and vanilla until smooth to create your icing. Drizzle this luscious glaze over the cooled cookies, letting it set before diving in.
How to Serve Iced Oatmeal Cookies – Crumbl Copycat Recipe
Garnishes
Sprinkle a little extra cinnamon or a dash of finely chopped toasted nuts over the icing for a beautiful, flavorful touch. You could also drizzle a bit of melted dark chocolate for a decadent variation that pairs perfectly with the sweetness of the glaze.
Side Dishes
These cookies go wonderfully with a hot beverage like chai tea, coffee, or even a fresh glass of cold milk. The warm spices and soft oats complement the cozy drinks, making each bite feel like a small celebration.
Creative Ways to Present
For a party or gift, stack these iced oatmeal cookies in a pretty jar with layers of parchment paper between each cookie to keep them from sticking. You can also arrange them on a rustic wooden board alongside seasonal fruit for a charming dessert spread that’s sure to impress.
Make Ahead and Storage
Storing Leftovers
Keep your iced oatmeal cookies in an airtight container at room temperature for up to 4 days. This helps maintain their soft texture and keeps the icing from hardening too much.
Freezing
If you want to save some for later, freeze the un-iced cookies in a single layer on a baking sheet, then transfer them to a freezer-safe bag or container. When you’re ready, thaw and ice them fresh. This method preserves the chewy texture beautifully.
Reheating
Warm leftover cookies gently in a microwave for about 10 seconds or in a low oven (around 300°F) for a few minutes to revive their soft, cozy feel. Avoid overheating or the icing can melt too much and become sticky.
FAQs
Can I substitute the butter with a healthier fat?
While you can try using coconut oil or margarine, butter offers the best flavor and texture for this recipe. Using substitutes may change the cookie’s softness and taste.
Why are my cookies flat?
Make sure your baking soda is fresh and that you don’t over-mix the dough, which can cause the cookies to spread more. Also, chilling the dough slightly before baking can help cookies maintain their shape.
Can I add raisins or nuts?
Absolutely! Adding a half cup of raisins or chopped nuts can give your cookies extra texture and flavor that some people love in oatmeal cookies. Just fold them in with the dry ingredients.
Is it okay to use quick oats instead of old-fashioned rolled oats?
Old-fashioned oats hold up better to baking and provide that classic chewy texture. Quick oats can make the cookies denser and less chewy, but they can be used in a pinch.
How thick should the icing be?
You want the icing thick enough to drizzle but not so runny that it pools on the pan. Adjust the milk amount gradually until you reach a pourable but slightly thick consistency.
