Chewy Chocolate Chip Oatmeal Cookies

These chewy chocolate chip oatmeal cookies can be made in one-bowl, don't require chilling the dough OR using room temperature softened butter, and are soft as can be!

Whip up in under 20 minutes and dip in milk for the perfect after school treat or allow them to cool and package them up for neighbor or teacher gifts! (I've included a link to some printable cookie pouches & gift tags below!)

My subconscious likes to think that chocolate chip oatmeal cookies are a little bit healthy because they have oats in them, but let's be honest and admit that's not really true.

Regardless, they're one of my favorite cookies because they are soft, chewy, easy to whip up, and use basic ingredients you likely have on hand.

I concocted this recipe last week after wanting a oatmeal cookie that wasn't too oatmealy or dry, but instead had a soft and chewy texture.

And my friends, I think I achieved that. And my favorite part is that you don't even have to set out the butter to soften a few hours before, as you can pop it in the microwave for a few seconds and get to mixing!

The trick to their chewy, softness? Using 2 egg yolks, 1 whole egg, and a touch of corn starch.

What You Need for Chewy Chocolate Chip Oatmeal Cookies:

• Unsalted Butter
• Brown Sugar & Granulated Sugar
• 3 eggs (2 egg yolks + 1 whole egg)
• Vanilla, Baking Soda, Baking Powder, Cornstarch, and Salt
• Quick Oats and All-Purpose Flour
• Semi-Sweet Chocolate Chips

How to Make Chewy Chocolate Chip Oatmeal Cookies

Step 1: Cream Butter & Sugar

Like I mentioned, this recipe does not need room temperature butter. Instead, take the stick of butter straight from the fridge, microwave for 10-20 seconds until it is slightly, slightly softened (when pinched, the sides should only slightly give) and then toss in the bowl.

Add the brown sugar & white sugar and mix on medium speed for about 30 seconds until it is creamy. It should look like the photo below.

Step 2: Add Eggs & Remaining Wet Ingredients

Once the butter and sugar mixture is creamed together, add the egg yolks, whole egg, and remaining wet ingredients and mix on low speed. Once mixed, add in the baking powder, baking soda, cornstarch, and salt and mix for another 5-10 seconds until combined.

Step 3: Add Oatmeal & Flour

Once the dough is mixed up, turn the mixer on medium speed and first add the oatmeal. Allow to mix together then add flour. Dough will be sticky. Stir in the chocolate chips and you're ready to scoop!

Step 4: Scoop & Roll

Use a 2-tablespoon sized cookie scoop to scoop dough onto parchment-lined baking sheet. The dough will be sticky, but this is how it should be. Once scooped, use your hands to roll each of the scoops into a ball. (If needed, spray your hands with non-stick cookie oil before rolling.)

Step 5: Bake, Press on Chocolate Chips, then Cool

Bake a 350 degrees for exactly 10 minutes. The edges should look slightly brown and the centers should look slightly underdone. Remove from the oven and allow the cookies to cool on the hot baking sheet for 10-15 minutes before removing them. This will allow them to finish baking on the hot sheet.

If desired, immediately press 4-5 chocolate chips on top of each hot cookie for a pretty presentation.

Step 6: Eat Warm or Package & Gift!

These cookies are delicious warm, but are also really good on Day 2 or 3 if stored in an airtight container or bag. To gift, allow them to completely cool (so the chocolate chips harden) and place in a plastic cookie bag, box, or wrap individually and slip in a printable cookie pouch.
