Trust me, you’ve never had oatmeal cookies like these before. They’re soft, chewy, and baked with brown butter for extra rich flavor. These cookies can be made by hand and require very few ingredients. All the flavor is the brown butter so need for extras!

Baking with Brown Butter

I have a separate post all about how to brown butter and ways to bake with it, but it’s especially delicious in these oatmeal cookies. It adds so much flavor to an otherwise basic cookie recipe, allowing the brown butter to stand out and let that richness shine through.

The process of making brown butter is very simple, the key is just knowing exactly when to take it off the heat.

To make it, add your butter to a saucepan over medium heat. Allow it to melt down and bubble (about 5-10 minutes). During this time you’ll be whisking occasionally.

The bubbles will slowly turn into a fine foam. Begin to whisk constantly to prevent the milk solids from burning on the bottom of the pot. These are what separate from the butter to create the browned and toasty flavor.

Keep whisking until the butter turns a light brown color. Remove from the heat and keep whisking until it turns into a rich amber color. Now you have brown butter!

Pour into a measuring glass and scrape up all the brown bits from the bottom of the pan. That’s where the flavor is.

Let it cool at room temperature for about 30-45 minutes, or until it’s no longer warm to the touch. It’s important to let the butter cool completely, otherwise it will melt the sugar and scramble the eggs when making the dough.

How to Make Oatmeal Cookie Dough

Once the brown butter is cooled, it’s time to prep the dough. The recipe itself is very simple and requires a few staple ingredients:

• Brown Butter
• Light Brown Sugar
• Eggs
• Vanilla
• Flour
• Old Fashioned Rolled Oats
• Baking Soda
• Salt

In a medium bowl, whisk together the flour, oats, baking soda, and salt.

In a large mixing bowl, whisk together the butter, brown sugar, eggs, and vanilla. It should turn fairly thick and smooth.

Dump in the dry ingredients and use a rubber spatula to fold the two together. Stop only once all the flour is absorbed as we don’t have to over mix. We want soft and chewy cookies, not tough and hard cookies!

Place the bowl in the fridge uncovered for just 20 minutes. This allows the oats to full absorb the wet ingredients, creating a thicker dough.

Can you use quick oats in oatmeal cookies?

Old fashioned rolled oats are preferred as they provide the best texture, but quick oats are great as a secondary option. Use the same amount and follow all the same instructions.

How to bake soft and chewy oatmeal cookies

When the 20 minutes is almost up, preheat the oven to 350F and line a large baking sheet with parchment paper.

There are a few different options when it comes to scooping the dough. This recipe makes about 15 large 2oz cookies. To make those, you can either use a large cookie scoop or weigh out each cookie using a food scale.

If you prefer smaller cookies, use a regular cookie scoop instead which will make closer to 20-22 cookies.

Either way, make sure to roll the dough in your hands into a perfect ball. Place 5-6 cookies on the baking sheet a few inches apart as they spread quite a bit. Gently press them down to where they’re about 1/2 an inch thick.

If baking large cookies, bake for 12-14 minutes. If baking regular cookies, bake for 10-12 minutes. You’re looking for a golden brown ring around the edge with a pale and puffed center.

The center will look a little undone, but that’s exactly what we want. The cookies will continue to bake when they’re fresh from the oven, and then settle to create the perfect soft and chewy texture.

Sprinkle the cookies with a little flaky sea salt and allow them to cool before digging in!

Optional Mix-Ins

If you want to take these cookies up ANOTHER notch, feel free to add your favorite mix-ins! For this recipe, chocolate chips, white chocolate chips, butterscotch chips, toffee bits, macadamia nuts, raisins, M&Ms, or any combo of those would be so delicious.

Adding 1 cup of anything would be the perfect amount. I would also recommend reserving a handful for dotting on top when they’re fresh from the oven…mainly for aesthetic purposes.

How to freeze oatmeal cookie dough

Since this makes a pretty big batch, you could either freeze the entire recipe or bake half now and save half for later.

Either way, scoop out the amount you’d like to freeze into round cookie dough balls. Place them on a plate or small tray and freeze for 30 minutes.

Remove from the freezer and add all the cookie dough balls into a zip lock freezer bag. They will keep for up to 1 month.

To bake, remove however many cookies you’d like and leave them at room temperature for about 1 hour or until they’re no longer frozen. Then bake according to the instructions listed in the recipe.

Troubleshooting your cookies

Although it’s a very simple recipe, there are a few things that could go wrong. If you run into any issues, these may be the reasons:

My cookies spread too much

This could be a couple reasons. One, you may have added too much butter. Make sure to measure out the brown butter to 3/4 cup exactly before adding to the dough.

The second reason could be that you forgot to chill the dough for 20 minutes. If you did chill them, then something went wrong with the dough. Don’t worry! If your first batch of cookies baked too flat, keep the dough in the fridge for another hour and try again. This may resolve the issue.

My cookies didn’t spread enough

This could happen for the exact opposite reasons of the first scenario. The main culprit for this is the flour. Make sure to spoon the flour into the measuring cup and level it off. Don’t pack it in or shake it down as this can lead to too much flour in the dough.

And the longer the dough sits in the fridge, the thicker it gets. If you forgot about the dough, just take it out and let it warm up for about 30 minutes at room temperature. This should help.

My cookies are too tough

For starters, under baking is KEY to a soft and chewy oatmeal cookie! When they’re ready to take out of the oven, they should have a golden brown ring around the edge and a puffed and pale center. They will look underdone, but they will continue to bake through once they’re out of the oven.

If they’re baked too long, this can lead to tough cookies. Another reason could be that you overworked the dough. Stop mixing right when all of the flour is absorbed to ensure a soft and tender cookie.

How to store your cookies

Keep these cookies in an air tight container at room temperature. They’ll keep for up to 5 days but they definitely won’t stick around for that long!

Can I cut the recipe in half?

Yes! Luckily most of the measurements are nice and round amounts, so it’s very easy to cut this recipe right in half. You can either bake the entire recipe and freeze half, or just make half.

The only tricky measurement in the butter. But if you make the brown butter using 8 tablespoons, you should have the right amount of butter for the recipe. To double check, half of 3/4 cup is 6 tablespoons.

Can these cookies be made gluten free?

Yes they can as the dough is very forgiving. Swap the oats with gluten free old fashioned oats and the flour with a 1-to-1 all purpose gluten free baking flour with xanthan gum (I like Bob’s Red Mill). They should bake up just fine!
