I’ve always been a fan of classic cookie recipes and this one is no exception. I’m really excited to share my take on The Best Crumbl Iced Oatmeal Cookies.
I recently whipped up a batch that has a thick, chewy base rich with 1 cup unsalted butter, 1 cup packed light brown sugar, and loads of old-fashioned rolled oats. It already felt like an upgrade on the classic oatmeal cookies.
Then i topped it off with a vanilla sugar glaze made from 1 cup powdered sugar, 2-3 tablespoons milk, and a bit of vanilla extract that gives it that smooth crunch. I love that these cookies aren’t just sweet treats but also provide some fiber, thanks to the oats, and a good balance of fats from butter.
They are the ultimate dessert recipes easy enough for weeknight baking and perfect for any cookie dessert craving. Enjoy these yummy cookies!
Why I Like this Recipe
I really love these cookies because they’re super thick and chewy with a crunchy vanilla sugar glaze that just hits the spot. I feel like I can always count on this recipe to give me that homestyle, comforting vibe, and it isn’t too hard to whip up even on a busy day. I also enjoy how the oats add a nice texture that makes every bite interesting without overwhelming the cookie. Another reason is that I can mix up some parts if im in the mood for something different, but the classic version always feels like a little piece of home.

FAQ
The Best Crumbl Iced Oatmeal Cookies Recipe Substitutions and Variations
- Unsalted butter: If you dont have unsalted, you can use salted butter but just cut the salt in the recipe by about 1/4 teaspoon.
- Light brown sugar: You can swap it with dark brown sugar to get a richer taste keeping the same measurement.
- Old-fashioned rolled oats: In a pinch, you can use quick oats, but expect a slightly different texture.
- Granulated sugar: Coconut sugar works as an alternative, though it might give a hint of coconut flavor.
- Powdered sugar for the glaze: If you only have icing sugar available, thats a perfect one-for-one swap.
Pro Tips
1. Make sure your butter is perfectly softened but not melted; if its too warm, your cookies might spread out way too much in the oven.
2. Be real careful not to overmix the dough when you add the dry ingredients. Stirring just until its combined makes the cookies stay soft and tender instead of getting all tough.
3. If you can, let the cookie dough chill in the fridge for about 15 minutes before baking. This helps the cookies hold their shape and gives you a better texture.
4. When whipping up the glaze, add the milk little by little until its the perfect drizzling consistency. Its easier to add more than try to fix a glaze thats too runny.
