Ingredients for Iced Oatmeal Cookies
Dry Ingredients:
- 2 cups old-fashioned oats
- 1 ยฝ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon cinnamon
- ยฝ teaspoon nutmeg
- ยฝ teaspoon salt
Wet Ingredients:
- ยฝ cup unsalted butter (softened)
- 1 cup brown sugar (packed)
- ยฝ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
For the Icing:
- 1 ยฝ cups powdered sugar
- 3-4 tablespoons milk (adjust for desired consistency)
- ยฝ teaspoon vanilla extract

How to Make Iced Oatmeal Cookies
Follow these easy steps to bake a batch of soft and chewy iced oatmeal cookies.
Step 1: Prepare the Oats
Place the old-fashioned oats in a food processor and pulse 4โ5 times. You want the oats to break down slightly while maintaining some texture. This helps create a perfectly chewy cookie.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the pulsed oats, flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
Step 3: Cream the Wet Ingredients
In a large mixing bowl, use a hand or stand mixer to cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2โ3 minutes. Beat in the eggs one at a time, followed by the vanilla extract, until well combined.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing, as this can make the cookies tough.
Step 5: Chill the Dough
Cover the dough with plastic wrap and refrigerate for at least 30 minutes. Chilling helps the cookies hold their shape and enhances the flavor.
Step 6: Bake the Cookies
Preheat your oven to 350ยฐF (175ยฐC) and line two baking sheets with parchment paper. Use a cookie scoop or tablespoon to drop 1 ยฝ-inch balls of dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake the cookies for 10โ12 minutes, or until the edges are golden brown. The centers may look slightly underbaked, but theyโll set as they cool. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Step 7: Make the Icing
In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more milk (for thinner icing) or more powdered sugar (for thicker icing).
Step 8: Ice the Cookies
Dip the top of each cooled cookie into the icing, letting the excess drip off. Place the cookies back on the wire rack and let the glaze set for about 20 minutes.
Variations and Add-Ins
Want to customize your iced oatmeal cookies? Here are a few ideas:
Raisin Oatmeal Cookies: Add ยฝ cup of raisins for a chewy, fruity twist.
Nutty Oatmeal Cookies: Mix in ยฝ cup of chopped walnuts or pecans for added crunch.
Chocolate Chip Oatmeal Cookies: Fold in ยฝ cup of mini chocolate chips for a touch of decadence.
Spiced Cookies: Increase the cinnamon to 1 ยฝ teaspoons and add a pinch of ground cloves for a warmer, spicier flavor.
Tips for Perfect Iced Oatmeal Cookies
Pulse the oats lightly: Donโt over-process the oats, as you want to maintain some texture for a chewy cookie.
Chill the dough: Refrigerating the dough helps prevent the cookies from spreading too much while baking.
Donโt overbake: The cookies should look slightly underdone in the center when you remove them from the oven. They will firm up as they cool.
Use room temperature butter: Softened butter creams more easily, resulting in a lighter, fluffier cookie dough.
Let the glaze set: Allow the icing to fully set before storing the cookies to prevent sticking.
How to Store Iced Oatmeal Cookies
At Room Temperature:
Store the cookies in an airtight container at room temperature for up to 5 days. Place wax paper between layers to prevent the icing from sticking.
In the Freezer:
For longer storage, freeze the un-iced cookies in an airtight container for up to 3 months. When ready to serve, thaw them at room temperature and ice them fresh.
