How to Make Iced Oatmeal Cookies – Crumbl Copycat Recipe
Step 1: Prep and Mix Your Base
Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This step ensures that your cookies bake evenly and don’t stick. Then, in a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture turns light and fluffy—this is key to achieving a soft, tender cookie.
Step 2: Add Egg and Vanilla
Next, crack in the egg, making sure it’s at room temperature for better mixing, and pour in the vanilla extract. Beat these into your creamed butter and sugars until everything is smooth and well combined, setting the stage for a moist and flavorful dough.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, old-fashioned rolled oats, cinnamon, nutmeg, baking soda, and salt. These dry ingredients introduce the signature texture and warming spice notes that define this Iced Oatmeal Cookies – Crumbl Copycat Recipe.
Step 4: Mix Dough and Shape Cookies
Gradually stir the dry ingredients into the wet mixture until just combined—avoid overmixing to keep your cookies tender. Using a cookie scoop, drop rounded dough mounds onto the prepared baking sheet and gently flatten them to encourage even baking.
Step 5: Bake to Perfection
Bake your cookies for about 10 minutes. You want them soft and slightly underbaked to maintain that chewy, melt-in-your-mouth quality. Once baked, let them cool on the sheet for 20 minutes to finish setting up before transferring to a wire rack.
Step 6: Make Icing and Finish
While the cookies cool, whisk together powdered sugar, milk, and vanilla to create a smooth and glossy icing. Drizzle this over the cooled cookies for that signature frosting finish that makes the Iced Oatmeal Cookies – Crumbl Copycat Recipe truly unforgettable.
How to Serve Iced Oatmeal Cookies – Crumbl Copycat Recipe
Garnishes
To elevate presentation and add a pop of flavor, consider sprinkling a pinch of cinnamon or a few rolled oats on the iced cookies. You could also lightly dust with crushed nuts such as walnuts or pecans for an added crunch and nutty aroma.
Side Dishes
A warm cup of chai tea or a creamy latte pairs beautifully with these cookies, enhancing their warm spice notes. For a refreshing twist, enjoy them alongside a glass of cold milk or vanilla almond milk to balance the sweetness delightfully.
Creative Ways to Present
For birthdays or gatherings, arrange these cookies on a rustic wooden platter lined with parchment paper and fresh sprigs of rosemary or thyme. Alternatively, create mini cookie sandwiches by spreading a thin layer of cream cheese frosting between two cookies for an indulgent treat.
Make Ahead and Storage
Storing Leftovers
Store any leftover Iced Oatmeal Cookies – Crumbl Copycat Recipe in an airtight container at room temperature for up to three days to keep them soft and flavorful. Placing a slice of bread inside can help maintain moisture and prevent drying.
Freezing
If you want to keep these cookies longer, freeze them uniced in a single layer on a baking sheet, then transfer to a freezer bag. They will stay fresh for up to two months. When ready, thaw completely before adding icing.
Reheating
Warm your cookies briefly in the microwave for about 10 seconds or in a low oven for a few minutes to bring back that fresh-baked softness and enjoy the icing at its meltiest best.
FAQs
Can I use quick oats instead of old-fashioned rolled oats?
Quick oats can be used, but the texture of the cookie will be finer and less chewy than the classic rolled oats version. For the best Crumbl-style chew, stick with old-fashioned rolled oats.
Is it okay to use margarine instead of butter?
Butter is highly recommended because it provides better flavor and texture. Margarine may result in less rich taste and a different cookie consistency.
Can I make the cookie dough ahead of time?
Absolutely! You can prepare the dough and refrigerate it for up to 24 hours before baking. This can even improve flavor as the oats and spices meld together.
How thick should I flatten the cookie dough on the sheet?
Flatten the dough just slightly, about half an inch thick. This helps them bake evenly while retaining a soft center without spreading too thin.
What if I want a dairy-free version of the icing?
You can substitute regular milk with any plant-based milk like almond or oat milk. Just make sure it’s unsweetened for the best icing consistency.
Final Thoughts
I can’t recommend this Iced Oatmeal Cookies – Crumbl Copycat Recipe enough for anyone who loves a cozy, sweet treat with a touch of nostalgic charm. It’s simple to make but feels incredibly special every time you take a bite. So go ahead, gather those ingredients, bake up a batch, and savor the comforting joy these cookies bring to your kitchen and your heart.
