Classic Peanut Butter Oatmeal Cookies are loaded with peanut butter and hearty oats. They are so good! If you love peanut butter, you will love these cookies.
In a large bowl, whisk the cooled melted butter, white sugar, brown sugar, and peanut butter for 1-2 minutes.
1/2 cup creamy peanut butter, 1/2 cup unsalted butter, 1/4 cup white sugar, 1/4 cup dark brown sugar
Then into the same large bowl add in vanilla and egg and whisk until well combined.
1 egg, 1 tsp vanilla
Add the dry into the wet and using a spatula, gently fold until a soft cookie dough forms. Do not over-mix!
Scoop the cookies using a cookie scooper (mine is 2 tbsp in size) and place 6 cookies per baking tray. These cookies do not flatten a lot in the oven, so if you like a flatter cookie, gently flatten before baking like displayed in the photo. If you like a thicker peanut butter oatmeal cookie, do not flatten the cookies.
Bake the cookies for 14-15 minutes. You'll know they're ready when the outside has a nice crisp edge and the middle is still soft. Remove from oven, the cookies will continue baking on the hot pan.
These cookies are so delicious! They stay good on the counter for a few days and in the fridge in an airtight container for a week. Enjoy!
Notes
Rolled oats - Also known as old-fashioned oats or large flake oats. Do NOT use quick oats.
