    My family voted these the best Crumbl cookies; we can't get enough of them. Lightly sweetened with just a hint of cinnamon, nutmeg, and vanilla, these cookies are so simple to make that you can bake a batch of these cookies anytime you have a cookie craving.

    Serve these classic homemade oatmeal cookies all year long; the kids love them for after school. I love them with my tea and coffee, and these are the perfect cookies for gift-giving. People will ask for this recipe.

    Why this recipe works

    Say goodbye to your old oatmeal cookie recipe because this one promises three things: a few ingredients, mixing and baking in 30 minutes, and a cookie with some UNBELIEVABLE flavor!

    Here’s how:

    • This is a one-bowl, super quick cookie recipe. Did I mention 30 minutes?
    • You don't need any special equipment; a hand mixer does the job.
    • These cookies are big, like the ones you get at the bakery.
    • These are simply the best-iced oatmeal cookies.

    Iced Oatmeal Cookie Ingredients

    Just look in your pantry for what you need

    Recipe for soft oatmeal cookies
    • Butter - I always use unsalted butter since I add salt to the recipe, but you can use salted butter and omit the salt in the recipe.

    Butter tip - Did you know there is only a ¼ to ⅓ teaspoon of salt in a stick of butter?

    • White sugar and brown sugar - help make these cookies chewy, and the brown sugar adds a great caramel flavor, which is never a bad thing. I prefer dark brown sugar, but if you have light brown sugar that will work too.
    • Rolled oats - I used quick oats for this recipe, but old fashioned oats will work.
    • Just one egg will help bind the ingredients and add moisture.
    • Flour - I use unbleached all-purpose flour.
    • Vanilla - Use the best you can buy for the cookies and the icing. I use the Native Vanilla Brand vanilla that adds a bit of floral flavor that we all love in baking; otherwise, your cookies will be bland without this spice. Here is a great guide to What is Vanilla.
    • Cinnamon and nutmeg - these two warming spices should just get married because when they are paired together, everything tastes wonderful. Learn about Baking with Spices for more about these and more spices.
    • Milk - use whole milk for a smooth and creamy icing.
    • Powdered sugar - used to make the icing.

    How To Make Oatmeal Cookies: With Step By Step Instructions

    Step 1. Heat the oven to 350 degrees F and prepare your cookie sheets with parchment paper.

    Step 2. In a large mixing bowl, add the room-temperature butter and both sugars. Then with a handheld mixer, mix on medium speed until creamy and fluffy. You can also use a stand mixer with the paddle attachment.

    Step 3. Add the egg and vanilla extract and mix again on medium speed until combined.

    Step 4. Add all the dry ingredients to the mixing bowl, then mix on medium speed until combined. Last, add the oatmeal and mix on low speed until combined.

    Dry ingredient tip - If you don’t mind, please get another bowl and mix all the dry ingredients before adding them to the wet ingredients. This will ensure that the baking soda, salt, and spices are evenly mixed. Clumps of baking soda can give a soapy taste.

    Step 5. Using a cookie scoop, scoop out 1" balls of cookie dough and place them on a cookie sheet.

    Step 6. Bake for 10-12 minutes until just starting to turn golden on the edges (the top will still appear a little soft.) Remove from the oven and let sit for about 10 minutes on the baking tray, then move to a cooling rack.

    Cookie Icing Ingredients

    Step 7. While the cookies are cooling, make the icing by adding all the ingredients to a small bowl and stir until smooth and creamy.

    Step 8. Place the wire rack over a piece of waxed paper or parchment paper and either dip the tops of the cooled cookies directly in the icing or spoon the icing over the cookies. The excess icing will drizzle off the cookies onto the waxed paper.

    How to store - Once the icing has hardened, store these cookies in an airtight container so they stay soft.

    Make Some Variations

    We all like to change things up and here are some tasty variations you can easily make to this recipe.

    • Make the classic oatmeal raisin cookies by adding a cup of raisins, or change this up and add dried cranberries instead.
    • I like mini chocolate chips in these cookies too.
    • Toffee bits will add a delicious caramel flavor.

    To Store

    To ensure the freshness of these oatmeal cookies, it is recommended to store them in a container that is airtight. Keeping them at room temperature would be ideal, and they should remain delicious for a period of 3-5 days (assuming they aren’t devoured before then)!

    Freezing Cookies

    • Place oatmeal cookie dough balls on a non-stick cookie sheet and put them in the freezer for 1-2 hours or until firm. 
    • Transfer to an airtight, freezer-friendly container (I recommend either a glass storage container or a freezer-friendly ziplock bag). 
    • Freeze for up to 3 months. 
    • To bake: remove dough from the freezer and let it come to room temperature. Then, bake according to the recipe instructions. 

    FAQs

    This recipe only makes nine cookies; how can you make more?

    You can make smaller cookies using a small cookie scoop, like a #40 scoop for a 1 ½" ball, or double the recipe.

    What makes oatmeal cookies delightfully soft and chewy?

    It's a combination of brown sugar and white sugar. Brown sugar infuses moisture and a caramelized richness, while white sugar encourages the cookies to spread and develop crispy edges, all while preserving that delectable chewiness at their centers.

    How do you tell when a cookie is baked?

    To determine if cookies are done, gently press the edges of a cookie. If they feel firm or set, it is an indication that the cookies are likely cooked. The center may still have a slight softness, which is often preferred for achieving chewy cookies.

    Equipment

    • 2 Baking sheets
    • 1 Hand Mixer
    • 1 Kitchen Aid Mixer
    • Parchment Paper
    • Cookie scoops Small, Medium, Large

    Ingredients
      

    Cookie dough

    • ½ cup unsalted butter room temperature
    • ⅓ cup brown sugar
    • ¼ cup granulated sugar
    • 1 large egg
    • 1 tablespoon pure vanilla extract
    • 1¼ cups quick cooking oats
    • 1 cup AP flour
    • ¼ teaspoon salt
    • ½ teaspoon baking soda
    • 1 teaspoon cinnamon
    • ¼ teaspoon nutmeg

    Icing for Oatmeal Cookies

    • 1 cup powdered sugar
    • 1½ tablesoon milk
    • 1 teaspoon pure vanilla extract

    Instructions
     

    The cookie dough

    • Line a baking sheet with parchment paper and heat the oven to 350°
    • In a large mixing bowl add the softened butter and the brown sugar and the granulated sugar. With a handheld mixer, or in the bowl of a stand mixer, cream these ingredients on medium speed until light and fluffy.
    • Add the egg and vanilla to the bowl and mix on medium speed to combine.
    • Add the dry ingredients, flour, salt, baking soda, cinnamon, and nutmeg to the bowl and mix on medium speed just until combined.
    • Add the oats to the bowl and mix on low speed to combine. Do not overmix.
    • With a large cookie scoop, scoop the dough into 1-inch balls and place them on the prepared baking sheet. Press the dough down slightly to flatten. I make nine 2-ounce dough balls.
    • Bake for 10-12 mins until just starting to turn golden on the edges (the top will still appear a little soft)
    • Let cool on the cookie sheet for 10 mins then move to a cookie rack to cool completely

    The cookie glaze

    • In a small bowl add all of the cookie glaze and mix to make a smooth icing.
    • Ice the cookies when they are completely cooled. Leave the cookies on the cooling rack that is set over a piece of waxed paper or parchment paper to catch the icing drips. You can dip the tops of the cookies into the icing, or drizzle the icing over the tops of the cookies. Return the cookies to the cooling rack until the icing has hardened.
    • Store the cookies in an airtight container for up to four days. You can also freeze these cookies once the icing has hardened. Just place them in an airtight container and freeze them for three months. Let thaw on the counter when ready to eat.

    Notes

    This recipe makes 9 4" cookies. You can easily make smaller cookies using a smaller cookie scoop like a #40.
    You can also double the recipe for more cookies.

        Adding raisins sounds delicious. I would add 3/4 to 1 cup, and add them right after you mix in the flour. This makes me want to go bake a batch of cookies now!

        For this recipe, I haven't tried freezing the dough so I don't know how they will taste if you do. I have frozen the baked and iced cookies and they still taste great.

        They still taste great, if anything, they are just a tad drier because of being frozen.

      Although I don't know what the original recipe tastes like, these were absolutely fantastic! Everything, from the cookie dough to the icing to how easy it was was great. I think next time I am going to add a few raisins, since oatmeal raisin cookies are my husband's favorite and the kids eat these ones too fast!
