You know those cookies that taste like a hug from your grandma? The ones with that perfect soft, chewy texture and a sweet vanilla glaze on top? Yeah, these are those cookies.
I used to think iced oatmeal cookies were just something you bought in a package at the grocery store, but then I made them from scratch and realized what I’d been missing.
They’re so simple, so cozy, and so much better when they’re homemade. The oats give them this hearty, tender texture, and that vanilla icing? It’s like the cherry on top of an already perfect cookie. These are the kind of cookies that make you want to pour a glass of milk and settle in.

Step-by-Step Instructions
Step 1: Preheat and Prep
Set your oven to 350°F and line a baking sheet with parchment paper. This keeps the cookies from sticking and makes cleanup a breeze. If you’re baking multiple batches, have a second baking sheet ready to go.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, add your softened butter, brown sugar, and granulated sugar. Use a hand mixer or a sturdy wooden spoon to beat them together until the mixture is light, fluffy, and well combined. The texture will be creamy and slightly pale.
Step 3: Add the Egg and Extracts
Crack in your room temperature egg, then add the vanilla extract and almond extract. Beat everything together until it’s smooth and creamy. Scrape down the sides of the bowl to make sure everything is incorporated.
Step 4: Mix the Dry Ingredients
Add the flour, oats, baking soda, cinnamon, salt, and nutmeg directly into the bowl with your wet ingredients. Use a spatula or wooden spoon to fold everything together gently. Mix until you don’t see any dry flour streaks, but don’t overmix. The dough will be thick and slightly sticky.
Step 5: Scoop the Dough
Use a large cookie scoop (about 1.5 tablespoons) to portion out the dough. You should get about 8 to 10 cookies depending on how big you make them. Place them on your prepared baking sheet, spacing them about 2 inches apart to allow for spreading.
Step 6: Flatten the Dough Balls
Gently press down on each dough ball with your palm or the bottom of a glass until they’re about 1 inch thick. These cookies don’t spread a ton in the oven, so shaping them now helps them bake evenly.
Step 7: Bake
Pop the baking sheet into your preheated oven and bake for 10 to 12 minutes. The edges should be set and just starting to turn golden, but the centers will still look slightly underdone. Don’t overbake. You want these cookies soft and chewy, not crispy.
Step 8: Cool on the Pan
Let the cookies cool on the baking sheet for a full 20 minutes. They’ll firm up as they cool but stay soft inside. After 20 minutes, transfer them to a wire rack to cool completely before icing.
Step 9: Make the Vanilla Icing
While the cookies cool, make your icing. In a medium bowl, whisk together the powdered sugar, milk, vanilla extract, and a tiny pinch of salt. Start with the full 1.5 tablespoons of milk and whisk until smooth. The icing should be thick and creamy but still pourable. If it’s too thick, add 1/2 teaspoon of milk at a time. If it’s too thin, add a tablespoon of powdered sugar.
Step 10: Ice the Cookies
Once your cookies are completely cool, it’s icing time. You can either dip the top of each cookie into the icing or use a spoon to drizzle it over. I like to dip them—it gives you that classic thick coating. Place the iced cookies back on the wire rack and let them sit for about 15 to 20 minutes until the icing sets.
Tips for Perfect Iced Oatmeal Cookies
#1 Don’t Skip the Cooling Time
I know it’s tempting to ice these while they’re still warm, but resist. If the cookies are even slightly warm, the icing will melt and slide right off. Let them cool completely first.
#2 Use Room Temperature Ingredients
Room temperature butter and eggs mix more easily and create a smoother dough. If your egg is cold, place it in a bowl of warm water for 5 minutes.
#3 Press the Dough Balls Down
Flattening them before baking ensures they bake evenly and don’t end up too thick in the middle.
#4 Watch the Bake Time
Oatmeal cookies can go from perfectly soft to dry and crumbly fast. Pull them out when the edges are set but the centers still look a little underdone. They’ll finish cooking on the hot pan.
Ingredient Swaps & Substitutions
No Butter? Use coconut oil (solid, not melted) or vegan butter. The texture will be slightly different but still delicious.
Dairy-Free Option: Swap the butter for vegan butter and use almond milk, oat milk, or any non-dairy milk in the icing. These cookies are easily dairy-free.
Gluten-Free? Use a 1:1 gluten-free flour blend and certified gluten-free oats. The texture might be slightly more crumbly, but the flavor stays great.
Out of Almond Extract? Just skip it. The cookies will still be delicious with vanilla alone. Or use 1/4 teaspoon more vanilla instead.
Storage & Make-Ahead Guide
- Room Temperature
Store iced cookies in an airtight container at room temperature for up to 5 days. Layer them with parchment paper so the icing doesn’t stick together.
- Refrigerator
You can refrigerate the cookies for up to a week if you prefer. Let them come to room temperature before eating for the best texture.
- Freezing Baked Cookies
Freeze iced cookies in a single layer on a baking sheet until the icing is solid, then transfer to a freezer-safe container. They’ll keep for up to 2 months. Thaw at room temperature for 30 minutes.
- Freezing Cookie Dough
Scoop the dough into balls, freeze on a baking sheet until solid, then transfer to a freezer bag. Frozen dough keeps for up to 3 months. Bake straight from frozen, adding 1 to 2 extra minutes to the bake time.

Frequently Asked Questions
Can I use quick oats instead of old-fashioned oats?
I don’t recommend it. Quick oats are more processed and will make the cookies mushy and dense. Old-fashioned rolled oats give you that perfect chewy texture.
Why are my cookies hard instead of soft?
You probably overbaked them. Oatmeal cookies need to come out of the oven when the centers still look slightly underdone. They’ll firm up as they cool but stay soft inside.
Do I have to use both vanilla and almond extract?
Nope! The almond extract adds a subtle depth, but you can leave it out if you don’t have it. Just use vanilla alone.

Make a batch of these tonight, and tomorrow-you will thank yourself. There’s something about iced oatmeal cookies that just feels right. Maybe it’s the nostalgia, maybe it’s the perfect balance of chewy and sweet, or maybe it’s just because they’re so dang easy to make.
Whatever it is, these cookies have a way of making everything feel a little cozier. So grab your oats, mix up that dough, and get ready to enjoy the softest, sweetest cookies you’ve had in a while. Your kitchen’s about to smell amazing, and your cookie jar is about to be empty.
