Iced Oatmeal Cookies Recipe with Soft Chewy Texture

Iced oatmeal cookies are a timeless, old-fashioned treat. These cookies are tender and chewy with a sweet vanilla glaze on top. The dough combines brown sugar, a touch of molasses, cinnamon, and vanilla for a rich, cozy oatmeal cookie flavor.

These iced oatmeal cookies are comforting alongside a cold glass of milk or a steaming cup of coffee or tea. I enjoy them most in fall and winter because the molasses and warm spice notes feel seasonal, but they’re delightful any time of year. The cookies bake up perfectly chewy, with the oats creating a textured top that holds the thick vanilla glaze beautifully.

If you think oatmeal cookies are dull, these iced versions will change your mind.

Making Iced Oatmeal Cookies

This recipe is adapted from a favorite chewy oatmeal cookie base. It uses a mix of quick oats and large rolled oats: the large oats add texture while the quick oats help the cookies hold a uniform shape. If you prefer thicker cookies you can chill the dough, though it’s not necessary for this version.

1. Prep. Preheat the oven and line your cookie sheets. Lining makes cleanup easier and prevents the bottoms from browning too much.
2. Whisk the Dry Ingredients. Don’t skip the cinnamon — it brightens the flavor. Measure flour carefully to avoid dry cookies; weighing or spooning and leveling are best.
3. Cream the Butter & Sugars. Use softened (not melted) butter for the right texture.
4. Mix in the Eggs, Molasses and Vanilla. Molasses adds both flavor and chewiness.
5. Add the Dry Ingredients to the Butter Mixture.
6. Stir in the Oats. You can do this by hand, but an electric mixer makes it easier to fully incorporate the oats.
7. Form into Balls. Use a cookie scoop (about 1½ tablespoons) and space dough balls about 2 inches apart on the prepared sheets.
8. Bake. Bake for roughly 9–12 minutes, until the tops are just set.

Allow the cookies to cool completely before glazing. If the cookies are still warm, the glaze will melt instead of firming up.

For the icing, whisk together powdered sugar, milk, vanilla extract and a pinch of salt. The glaze should be thick and opaque but still pourable. If it looks translucent, add a little more powdered sugar. I like to pour the glaze into a shallow dish and dip the cookie tops briefly; the icing should be tacky after dipping.

Make Ahead Tips

• The cookie dough can be chilled in the refrigerator for up to 48 hours before baking; cover it tightly.
• Dough balls can be frozen for up to two months and baked from frozen. Scoop dough onto a lined tray and chill until firm, then transfer to a freezer bag. Bake from frozen and add 1–2 minutes to the baking time if needed.

Equipment

• Cookie Sheets

Ingredients

Oatmeal Cookies

• 2 ¼ cup all-purpose flour (281 grams)
• 1 teaspoon baking soda
• 1/2 teaspoon cinnamon
• 1/2 teaspoon salt
• 1 cup unsalted butter (226 grams), softened but not melting
• 1 cup brown sugar (210 grams)
• 1 cup granulated sugar (200 grams)
• 1 tablespoon molasses, or honey
• 2 teaspoons vanilla extract
• 2 large eggs
• 1½ cup quick oats (about 135 grams)
• 1½ cup large rolled oats (about 135 grams)

Vanilla Icing

• 2-2½ cup powdered sugar (220–275 grams), sifted
• 2-2½ tablespoons milk
• ¼ teaspoon vanilla extract

Instructions

Oatmeal Cookies

• Preheat the oven to 350°F (180°C) and line cookie sheets with parchment paper or silicone mats.
• In a medium bowl, whisk together the flour, cinnamon, baking soda and salt. Set aside.
• In a large bowl, beat the butter, brown sugar and granulated sugar until creamy.
• Beat in the molasses, vanilla and eggs until combined.
• Stir the dry ingredients into the butter mixture until smooth.
• Mix in the oats until evenly distributed.
• Scoop dough into balls of about 1½ tablespoons and place 2 inches apart on the prepared sheets.
• Bake one sheet at a time in the center of the oven for 10–12 minutes, until the tops are just set.
• Cool the cookies on the sheet completely before icing.

Icing

• Whisk together 2 cups powdered sugar, 1½ tablespoons milk and the vanilla. If the glaze is too thin, add more powdered sugar; if too thick, add a little more milk. It should be opaque but still drizzlable.
• Ensure cookies are completely cool, dip the tops in the glaze, then place on a rack or tray to let the icing harden.

Notes

1. Molasses: You can substitute honey if you prefer a milder flavor.
2. Oats: A mix of quick oats and large rolled oats gives the best texture. If you only have one type, use 3 cups total of quick oats or 3 cups total of large rolled oats. Do not use steel-cut oats.
3. Storage: Store in an airtight container for up to five days. Make sure the icing is fully hardened before stacking.
4. Nutrition: Nutrition values are estimates per cookie, assuming 40 uniform cookies and all icing used.
