These iced oatmeal cookies are the ultimate sweet treat when you want something soft, chewy, and just a little bit special with a simple glaze on top. They come together quickly and hold a nostalgic spot for anyone who loves classic cookies with a cozy flavor twist.
I first made these on a lazy Sunday afternoon and they instantly became the cookie I reach for when I want something homemade but effortless.
Ingredients
- Shortening: lends a tender crumb and makes the cookies soft make sure it is at room temperature for smooth creaming
- Brown sugar: adds moisture and a rich caramel-like depth that balances the oats well packed firmly for accuracy
- All-purpose flour: gives just the right structure without weighing the cookie down
- Baking soda: helps them rise perfectly without becoming cakey
- Salt: enhances the overall flavors balancing the sweetness
- Nutmeg and cinnamon: provide warm cozy spices essential for that classic oatmeal cookie taste
- Oats: whether quick cooking or old fashioned bring that slightly chewy texture and wholesome body
- Milk: smooths out the glaze and allows it to set just right—choose whole milk for the best richness
- Powdered sugar: is perfect for a smooth glossy glaze that hardens quickly on the cookies
- Vanilla extract: brightens the flavor lifting the entire cookie from good to memorable
- Water: helps both in the dough and adjusting the glaze consistency enabling a perfect dip every time
Instructions
- Build The Creamy Base:
- In a large bowl cream the shortening with both brown and white sugar until the mixture is light and fluffy. This step traps air and lays the foundation for a soft chewy texture. Room temperature shortening really makes a difference here so be patient.
- Add The Liquids And Spices:
- Beat in the water and vanilla extract until fully combined. In a separate bowl whisk together flour baking soda salt nutmeg and cinnamon. Gradually mix the dry ingredients into the creamed mixture to ensure an even distribution of the spices and leavening which gives you a balanced cookie flavor and perfect rise.
- Fold In Oats:
- Carefully fold the oats into the dough folding slowly to keep the mixture airy while making sure every bite has that signature oat chew.
- Scoop Onto Sheets:
- Drop dough by rounded scoops onto greased baking sheets spaced adequately apart. I like to use a medium cookie scoop for uniform size and even baking.
- Bake To Golden Perfection:
- Bake in a preheated oven at 350 degrees Fahrenheit for 10 to 12 minutes. Look for a nicely golden edge with a slightly softer center. The cookies will firm up as they cool. Let them stand on the sheet for 2 minutes after baking before transferring to a cooling rack. This resting time helps prevent breakage.
- Make The Glaze:
- While cookies cool combine the milk and sifted powdered sugar in a bowl stirring until smooth. Add water slowly one teaspoon at a time until you reach a glaze consistency that is thick enough to coat the back of a spoon but still fluid.
- Glaze The Cookies:
- Quickly dip the top of each cooled cookie into the glaze letting the excess drip back into the bowl for a shiny sweet finish that sets beautifully.

Cinnamon is my favorite here because it adds that autumn warmth and pairs perfectly with the molasses notes from the sugar. I remember making these with my grandmother and how the house smelled amazing as the cookies baked.
Storage Tips
Store cookies in an airtight container at room temperature and they will stay soft for up to five days. If they begin to firm up a quick 10 second zap in the microwave softens them nicely. The glaze may crack a little but the flavor holds strong.
Ingredient Swaps
Try replacing half the shortening with butter for a richer flavor but watch for slightly crispier edges. Use maple syrup instead of vanilla for a lovely maple twist. Swap out the spices for pumpkin pie seasoning for a seasonal spin or add raisins for extra chew.
Serving Ideas
Serve alongside a warm cup of chai tea or cold milk for maximum comfort. Top with a sprinkle of chopped nuts right after glazing for an extra crunch. Pair with fresh fruit or yogurt for a balanced snack.

Classic iced oatmeal cookies are timeless and once you master this simple glaze finish you will find they become one of your go-to baked goods that bring back fond memories with every bite.
