The Best Small Batch Oatmeal Cookies

Jump to Recipe Print Recipe

Oatmeal girlies unite. Because these small batch oatmeal cookies are the absolute best! They are soft, chewy, and have a combination of brown butter and brown sugar for a toffee-like sweetness. No-chill, one-bowl, and you'll end up with just 6 stunning cookies.

Listen, friends. The world is weird right now. Listening to the news makes me question my sanity. And so please don't judge me when I tell you this. The other night, I baked up these oatmeal cookies and ate almost the entire batch while I watched Bob's Burgers reruns. It was a 10/10 night.

Rage baking has been my personal form of self-care ever since I was a student in pastry school. Nothing gets out the frustration quite like whisking the hell out of some butter and sugar for small batch brownies. Or smacking a pan to get perfect crinkle tops on small batch chocolate chip cookies.

But these oatmeal cookies are my personal go-to because I literally always have the ingredients on hand. And I know, they look unassuming. But these cookies are ridiculously good. Even my friends who don't like oatmeal cookies like this recipe. Grab a stick of butter and let's take out some of our frustrations, amen.

Quick vs. old fashioned oats

White bowls of oats, vanilla, butter, cornstarch, salt, baking soda, brown sugar, flour, and an egg yolk on a tan counter.

A lot of oatmeal cookie recipes call for quick oats, which will totally work in this recipe. But personally, I like old fashioned oats because they have more texture! They give these cookies a nice oat-y crunch which I'm all about. Use whatever you have though. You'll also need unsalted butter, light or dark brown sugar, an egg yolk, vanilla extract, all-purpose flour, cornstarch, baking soda, and Kosher salt.

How to brown the butter

Melt the butter in a large skillet. It will sputter & foam up a bit.

Let it cook for 5-7 minutes, until the butter smells nutty & has brown bits at the bottom.

Since we're not using very much butter in this recipe, it will brown quickly! Keep a close eye so it doesn't burn.

Bake the cookies

Add the cooled brown butter & brown sugar to a bowl.

The key to cookies that are nice and chewy is to under-bake them just a little. The cookies will have a rim that is set and golden-brown with a slightly under-baked center. Don't worry, they'll keep baking on the pan as they cool!

Freeze the dough

What I love about this cookie dough is that you can freeze it and bake it whenever. No need to defrost or anything, just add 1-2 minutes to the bake time!

To freeze the dough, scoop it into balls, place it on a parchment-lined sheet pan, and freeze until solid, 1-2 hours. Pop the cookie dough balls in a parchment-lined zipper bag or container and freeze for up to 3 months.

You can also freeze the baked cookies. Just place them in a zipper bag or airtight container lined with parchment paper and freeze for 2-3 months.

Storing leftover cookies

Place leftover cookies in an airtight container and store them at room temp for up to 2 days. They start to get hard after 2 days, so they're best fresh!

When it comes to small batch baking, I always recommend using a scale to measure the ingredients. Just a small amount of flour can make or break an entire recipe. But if you don't have a scale, use the fluff, spoon, & level method to measure flour, cocoa, & other dry ingredients. Here is a whole guide on how I measure ingredients for small batch baking!

Equipment

  • Kitchen scale or measuring cups
  • 1 sheet pan
  • Parchment paper
  • #20 cookie scoop

Ingredients
  

  • 60 grams unsalted butter (¼ cup)
  • 76 grams brown sugar, dark or light (6 Tablespoons, packed)
  • 1 large egg yolk, room temperature
  • 1 teaspoon pure vanilla extract
  • 40 grams all-purpose flour (⅓ cup)
  • 5 grams cornstarch (½ Tablespoon)
  • 50 grams old fashioned oats (scant ½ cup)
  • ¼ teaspoon baking soda
  • ¼ teaspoon Kosher salt

Instructions
 

  • Preheat the oven to 350°F (177°C). Line a sheet pan with parchment paper.
  • Melt the butter in a medium skillet over medium-low heat. Bring it to a gentle simmer. It will foam up a bit. Cook the butter, swirling the pan often, until the butter smells nutty and has brown bits at the bottom, about 5-7 minutes. Pour the butter into a medium mixing bowl and let it cool slightly.
  • Then, add the brown sugar to the brown butter and whisk until well-combined. The mixture will be grainy. Add the egg yolk and vanilla extract. Whisk until the mixture is thickened and fluffy, another 1-2 minutes.
  • Add the flour, cornstarch, old fashioned oats, baking soda, and salt. Using a rubber spatula, fold the dry ingredients into the butter-sugar mixture just until the dough is well-combined and there are no more streaks of flour. Don't over-mix!
  • Using a #20 cookie scoop (3 Tablespoons), divide the dough into 6 large balls of dough. Roll each ball of dough and place the cookies about 3 inches apart on the prepared sheet pan.
  • Bake the cookies for 8-9 minutes, until the edges are set and the tops are a just bit underdone. Let the cookies cool on the sheet pan for about 5 minutes. Then, transfer them to a wire rack to cool completely. Enjoy!

Notes

When it comes to small-batch baking, I always recommend using a scale to measure the ingredients. If you don't have a scale, here's how to measure the flour. First, whisk the flour until it's light and fluffy. Then, spoon the fluffed flour into a measuring cup until it's overflowing. Lastly, use a straight edge to level it off without packing the flour into the cup.
I use ¼ teaspoon of Morton's Kosher salt in this recipe. If you use Diamond, increase the salt by another ⅛-1/4 teaspoon.
It may seem like there's too much flour and oats when you first start mixing, but just keep folding. The dough will eventually come together!
If you like a crispier cookie, bake the cookies for another 1-2 minutes. Just make sure the bottoms don't burn.
