These delicious oatmeal cookies bring back memories of baking with my grandma. Each cookie has the perfect crispy edges and soft centers filled with cozy spices. The sweet glaze on top makes them absolutely irresistible with a cold glass of milk.

My Perfect Fall Cookie

I absolutely love baking during autumn months and these cookies are on constant repeat in my kitchen. The oats give such an amazing texture that my family cant get enough of. Living here in Utah where the weather is getting cooler, I find myself craving these spiced treats more than ever. The thin sweet glaze truly makes these cookies extra special.

What Goes Into These Cookies

  • Oats: I use old-fashioned oats because they give that perfect chewy bite every time.
  • Warm Spices: The combination of cinnamon and nutmeg creates that cozy flavor I love.
  • Sweeteners: A mix of regular and brown sugar adds wonderful depth.
  • Flour: Regular all-purpose flour works perfectly here.
  • Baking Essentials: Baking powder and salt make these cookies just right.
  • Glaze: A simple mix of powdered sugar and milk creates that gorgeous topping.

Baking Your Cookies

Make Your Dough

Let it Rest
Pop your dough in the fridge for 30 minutes so your cookies wont spread too much while baking.
Time to Bake
Scoop dough onto your baking sheet and bake at 350°F until you see golden edges, about 10-12 minutes.
Finish with Glaze
Stir powdered sugar and milk until smooth then drizzle over completely cooled cookies.

Where This Recipe Came From

Frequently Asked Questions

→ How long do iced oatmeal cookies stay fresh?

These cookies stay fresh for up to 5 days when stored in an airtight container at room temperature. Make sure they're completely cool before storing to keep the icing intact.

→ Can I freeze these cookies?

You can freeze the unglazed cookies for up to 3 months in a freezer-safe container. When ready to serve, thaw them completely at room temperature, then add the icing fresh for best results.

→ Why do you pulse the oats?

Pulsing the oats creates different textures throughout the cookie, giving you both finer and coarser pieces. This creates the perfect chewy texture while maintaining that classic oatmeal cookie appearance.

→ What makes the icing crack on top?

The crackled effect happens when you quickly dip and lift the cookies from the icing while it's still wet. The thickness of the icing and immediate lifting creates those beautiful peaks and valleys as it sets.

→ Can I make these cookies smaller or larger?

Yes, you can adjust the size of your cookies. Smaller cookies will need about 8-9 minutes to bake, while larger cookies might need 10-11 minutes. Just watch for lightly browned edges to know they're done.

Bake 9-10 minutes until edges start browning. Let rest a few minutes, then move to cooling rack.

Step 08

Whisk powdered sugar and vanilla extract. Slowly add milk until it's thick but pourable.

Step 09

Quickly dip tops of cooled cookies in glaze, immediately lift straight up. Let excess drip off. Place on rack until glaze sets.
