Ingredients List
Cookies
2 cups old-fashioned rolled oats
2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon kosher salt
1 ½ teaspoons cinnamon
1 cup unsalted butter, softened to room temperature
1 cup light brown sugar, packed
½ cup granulated sugar
2 large eggs, room temperature
2 teaspoons vanilla extract
Substitution tips
Old-fashioned rolled oats provide the classic texture, but quick oats can be used for a slightly smoother cookie. Light brown sugar adds caramel depth, while dark brown sugar creates an even richer flavor. If using salted butter, reduce the kosher salt to ½ teaspoon.
Icing
2 cups confectioner’s sugar, sifted
½ teaspoon vanilla extract
2 to 2 ½ tablespoons milk
This icing sets beautifully and creates the signature glossy finish seen in traditional iced oatmeal cookies.

Step-by-Step Instructions

Step 1: Mix Dry Ingredients
In a medium bowl, combine oats, flour, baking soda, salt, and cinnamon. Mixing these first ensures even spice distribution throughout the cookies.
Step 2: Cream Butter and Sugars
In a large bowl, beat butter, brown sugar, and granulated sugar on medium speed for 1–2 minutes until fully blended and creamy. This step creates a soft, tender cookie texture.
Step 3: Add Eggs and Vanilla
Add eggs and vanilla extract. Beat on high speed for about 1 minute until light and well combined.
Step 4: Combine Dough
Add the dry ingredients to the wet mixture and mix on low speed just until combined. Avoid overmixing to keep the cookies soft.
Step 5: Chill the Dough
Chill the dough for 45 minutes. This allows the oats to absorb moisture and prevents excessive spreading during baking.
Step 6: Prepare for Baking
Preheat oven to 350℉ (175℃). Line baking sheets with parchment paper to ensure even baking.
Step 7: Scoop and Bake
Scoop about 1½ tablespoons of dough per cookie, spacing them 2–3 inches apart. Bake for 10–12 minutes until edges are lightly golden but centers remain soft.
Step 8: Cool Completely
Let cookies cool on the baking sheet for 8–10 minutes, then transfer to a wire rack. Cookies will firm up as they cool.
Step 9: Make the Icing
In a shallow bowl, whisk confectioner’s sugar, vanilla, and milk one tablespoon at a time until thick but pourable.
Step 10: Ice the Cookies
Once cookies are fully cooled, dip the tops into the icing. Lift straight up, allow excess to drip off, then place back on the rack. Let icing set for 15–30 minutes.

Healthier Alternatives for the Recipe
To make a lighter version of this OLD FASHIONED ICED OATMEAL COOKIE RECIPE, substitute half the flour with whole wheat flour. Reduce icing by half or drizzle instead of dipping. Coconut sugar can replace brown sugar for a deeper, less refined sweetness.
Serving Suggestions
Serve these cookies with coffee, tea, or milk for a cozy treat. They’re perfect for holiday cookie trays, lunchbox desserts, or afternoon snacks. For a festive twist, add a pinch of nutmeg or ginger to the dough.
Common Mistakes to Avoid
Skipping the chill time causes cookies to spread too thin. Overbaking removes the soft texture. Icing warm cookies will cause the glaze to slide off instead of setting properly.
Storing Tips for the Recipe
Store baked cookies in an airtight container at room temperature for up to one week. Freeze baked or unbaked dough for up to 3–4 months. Always allow iced cookies to set fully before storing.
