Tips & Variations

Use old-fashioned rolled oats rather than quick oats for better texture.
Add chopped nuts like walnuts or pecans to the dough for extra crunch.
Swap chocolate chips for raisins or dried cranberries for a fruitier twist.
For a different icing flavor, try substituting vanilla with almond or maple extract.
Chilling the dough for 30 minutes before baking can help cookies hold their shape better.

Storage

Store iced cookies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Allow refrigerated cookies to come to room temperature before eating. Iced cookies can also be frozen for up to 2 months; thaw completely and refresh icing if needed.

FAQs

Can I make these cookies gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend that can be used cup-for-cup. Ensure oats are certified gluten-free to avoid cross-contamination.

How do I prevent the icing from melting on warm cookies?

Make sure the cookies are completely cool before spreading the icing. Warm cookies will cause the icing to melt and can make it runny.

2 tablespoons unsalted butter, softened
1 teaspoon vanilla extract
Pinch of salt
Optional: Food coloring (light blue recommended)

Instructions

Preheat Oven: Preheat your oven to 375°F (190°C) and line your baking sheets with parchment paper to prevent sticking and ensure easy cleanup.
Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set this mixture aside for later use.
Cream Butter and Sugars: In a large bowl, beat the softened butter, granulated sugar, and light brown sugar together until the mixture is light and fluffy. This creates the base for the cookie dough.
Add Eggs and Vanilla: Add the eggs one at a time to the butter-sugar mixture, beating well after each addition, then stir in the vanilla extract for flavor.
Combine Dry and Wet Ingredients: Gradually add the dry flour mixture to the wet ingredients on low speed, mixing until just combined to avoid overmixing, which can toughen the cookies.
Incorporate Oats and Chocolate Chips: Gently fold in the rolled oats and chocolate chips to distribute them evenly throughout the dough.
Prepare Crumble Topping: In a small bowl, combine the flour, rolled oats, brown sugar, and ground cinnamon. Pour in the melted butter and mix until the mixture becomes crumbly.
Form Cookies on Baking Sheets: Drop rounded tablespoons of the cookie dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
Add Crumble Topping: Evenly sprinkle the prepared crumble topping over each mound of cookie dough.
Bake Cookies: Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown while the centers remain slightly soft.
Cool Cookies: Let the cookies cool on the baking sheets for a few minutes to firm up before transferring them to a wire rack to cool completely.
Prepare Icing: In a medium bowl, whisk together the powdered sugar, milk, softened butter, vanilla extract, and a pinch of salt until smooth and creamy. Add food coloring if desired for a colorful finish.
Ice the Cookies: Once the cookies are completely cooled, spread the icing over each cookie evenly using a knife or spatula.
Set Icing: Allow the icing to set fully before serving or storing the cookies to prevent smudging.

Notes

For softer cookies, reduce baking time slightly and check at 10 minutes.
You can substitute chocolate chips with raisins or nuts for variety.
Adjust the milk in the icing to reach your desired consistency.
Use parchment paper or silicone baking mats to avoid sticking during baking.
Store iced cookies in an airtight container at room temperature for up to 3 days.
