Hey guys! Back with another cookie today, and it’s actually a recipe from my first cookbook Sugar High! This is one of the most overlooked recipes, and it’s seriously so good!

Thin Oatmeal Cookies

This recipe is super simple, and you end up with these big oatmeal treats that are chewy in the middle and lightly crisp on the edges- seriously the texture is addictive. I’m super into a classic and simple oatmeal cookie, and these are the perfect ones to add to your holiday baking list!

How to Make Oatmeal Cookie Thins

These cookies come together really easily, and it’s your basic cookie mixing method. We’re starting out by beating together some butter, white sugar, and brown sugar until fluffy. Then we’re adding in the egg and vanilla extract.

Finally, we’re adding in the dry ingredients and mixing until everything is well combined. It’s super simple!

Then I like to use a cookie scoop to scoop these cookies out onto a large baking sheet. These cookies spread a good amount as they bake, so you want to leave about 2 inches between each cookie. I also decided to sprinkle a little flakey salt on top this time and it was seriously SO good!

And then they’re off to the oven! The cookies will look slightly puffy and just barely golden brown on the edges when they are finished baking- they will settle and continue cooking as they cool. Enjoy yourself a chewy, crisp, oatmeal cookie!

Tips & Tricks for the Perfect High-Altitude Oatmeal Cookie

These cookies are a simple thin oatmeal cookie that I’m seriously obsessed with, and they are super easy! Here are my tips and tricks to help you along the way:

  • Cream the butter and sugar together well until it’s light and fluffy. this should take a good 5 minutes or so. It makes a big difference!
  • Don’t over mix the cookie dough but mix it enough to make sure that everything is well incorporated. The dough is pretty soft, so you should be able to give it a couple of good stirs after it’s finished mixing with an electric mixer just to ensure everything is evenly mixed.
  • Press down the cookie dough gently before baking. You don’t need to press them down a ton, just a gentle press will help the cookies bake and spread more evenly
  • Add flakey salt to the top optionally. This wasn’t a part of my original recipe, but it’s seriously SO good, so I recommend the addition!
  • Don’t over bake the cookies. As always, keep a close eye on these cookies as they bake. You want them to look just lightly golden around the edges and a little puffy all over when you pull them out of the oven. Remember that they will continue to cook and settle as they cool!
  • Store in an air-tight container for up to 5 days while keeping that perfect chewy texture.
  • I’m at about 5,000 ft. above sea level and I find that most people who live between about 3,000-7,000 ft above sea level do not need to make any adjustments to my recipes!

    My cookie dough came out really dry. Any idea what I might have done wrong?

      Hi there- so sorry to hear that it came out dry. Sometimes this can happen based on differences in how we measure ingredients. Were you using old fashioned oats (not instant?), and a full two tsp of vanilla extract?
