Step-by-step directions
These iced oatmeal cookies come together quickly with simple ingredients and easy steps. Follow this method for perfectly chewy cookies with a crisp, sweet glaze.
Prepare the oat mixture
Give the oats a quick pulse in a food processor—just enough to break them down slightly. This simple trick helps keep the cookies soft while still delivering that classic chewy texture. In a large bowl, whisk together the oats, flour, baking powder, salt, cinnamon, and nutmeg until well combined. Set aside while you get the wet ingredients ready.
Mix the wet ingredients
In a separate large bowl, cream together the butter, brown sugar, and granulated sugar until the mixture is light, fluffy, and downright irresistible—about 2 minutes. Beat in the eggs and vanilla extract, mixing until everything is smooth, creamy, and perfectly blended.
Combine and chill
Slowly fold the dry ingredients into the wet mixture, stirring just until everything comes together. Avoid overmixing—this keeps the cookies soft and perfectly tender. Pop the dough in the fridge for at least 30 minutes to let the flavors deepen and ensure thick, chewy cookies that hold their shape while baking.
Shape and bake
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup. Scoop out tablespoon-sized portions of dough, roll them into balls, and space them about 2 inches apart on the baking sheet. Bake for 10–12 minutes, until the edges turn golden brown but the centers stay soft. Let them rest on the baking sheet for 5 minutes before moving them to a wire rack to cool completely—if you can wait that long!
Make the icing and glaze
As the cookies cool, whisk together powdered sugar, milk, and vanilla extract in a small bowl until the glaze is silky smooth. Dip each cookie or drizzle the icing generously over the tops, letting it melt into every little crack and crevice for that perfect sweet finish. Place them on a wire rack and let them rest for about 15 minutes to set—though the temptation to sneak a bite will be strong! For the ultimate bakery-style look, let the glaze fully harden before stacking or storing… that is, if they don’t disappear first!

Take your iced oatmeal cookies to the next level with these creative customizations and delicious pairings.
Customization and variations
- Spice it up: add a pinch of cardamom, nutmeg, or ground ginger to bring out the warm, cozy flavors. These spices complement the cinnamon beautifully and add depth.
- Crispy edges: for cookies with a slight crunch, bake them for an extra 2 minutes, letting the edges turn golden brown while keeping the center soft.
- Soft and chewy: love a softer bite? Slightly underbake the cookies by 1–2 minutes and allow them to finish baking on the hot cookie sheet. This keeps them irresistibly chewy.
- Maple twist: swap vanilla extract in the icing for maple extract to enhance the oatmeal’s natural sweetness with a cozy, caramel-like flavor.
- Chocolate drizzle: instead of classic icing, melt white or dark chocolate and drizzle it over the cookies for a decadent upgrade.
- Dairy-free option: replace butter with coconut oil and use almond or oat milk in the icing for a completely dairy-free version. The slight coconut flavor adds a delicious twist.
- Gluten-free version: use a 1:1 gluten-free flour blend in place of all-purpose flour to make these cookies celiac-friendly without compromising texture.
Servings and pairings
- Classic duo: the ultimate pairing? A warm, freshly baked iced oatmeal cookie with a tall glass of cold milk. Simple, nostalgic, and always satisfying.
- Brunch treat: serve these alongside strawberry waffles for a delicious contrast of fruity and spiced flavors. Perfect for weekend brunch spreads.
- Tea-time delight: pair with a cup of chai, Earl Grey, cinnamon-infused black tea, or lemon balm tea for a cozy afternoon snack. The spices and citrusy notes enhance the warmth of the cookies.
- Elegant dessert plate: for a fancier presentation, serve the cookies with a scoop of vanilla bean ice cream and a drizzle of warm caramel sauce.

Why are my oatmeal cookies always dry?
The usual culprits are overbaking, too much flour, or not enough butter. Stick to precise measurements and try adding a touch of honey or molasses for extra moisture.
Why are my oatmeal cookies gummy?
