What You Need

Are you ready to make the most delicious peanut butter oatmeal cookie recipe you’ve ever tasted? Check out these simple ingredients:

  • quick-cooking oats: we’ve made this recipe with both quick-cooking oats and rolled oats. We prefer quick-cooking oats, but either works!
  • butter: we haven’t tested this with any other fat, but let me tell you, butter makes these extra delish!
  • brown sugar: make sure to pack your light brown sugar when measuring.
  • maple syrup: a little bit of maple syrup helps these peanut butter oatmeal cookies become nice and chewy. It also adds a hint of warmth.
  • egg: don’t skip the egg! We haven’t tested this without it.
  • peanut butter: we used normal creamy peanut butter in this recipe, but I’ve also made them with drippy, all-natural peanut butter. Either should work.
  • vanilla: a little goes a long way!
  • baking soda: baking soda is used to help these cookies flatten a bit, but not too much!

Baking Tips & Tricks

These are our top 3 tips to make the most perfect peanut butter oatmeal recipe of all time.

Roll & Pat: Rolling and slightly patting is the most important part of baking perfectly round peanut butter oatmeal cookies.

Scoop 2 tablespoons of cookie dough (yes these are big cookies!) into your palms and roll it into a ball. Then, slightly pat it down to form a cookie shape. Don’t worry about patting it down too much, you just want to help get it started!

Bake until golden: All ovens are different and that’s a fact. The cook time should be anywhere between 11 and 14 minutes, but the real way to get perfectly baked peanut butter oatmeal cookies is by baking until they start to turn golden brown.

Let cool: Once your cookies are done baking, they will seem pretty soft and fragile. You MUST let them cool for at least 15 minutes to firm up before eating.

Variations

  • Chocolate Chips: mix in around 3/4 cup semi-sweet chocolate chips to the batter before rolling into cookie dough balls.
  • Use almond butter: can’t do peanut butter? Swap the peanut butter for a drippy almond butter.
  • Brown butter: instead of using regular melted butter, make brown butter and mix that into your cookies.

Storage

Let cookies cool completely. Then, transfer cookies into an airtight container and store them in a cool, dark place for up to 5 days.

Freezer Instructions

Let cookies cool completely. Then, transfer cookies into a freezer-safe gallon-size bag or container. Remove as much air as possible and then seal. Freeze for up to 3 months.

Fat 10 Carbs 23 Protein 5

Ingredients

  • 1/4 cup melted unsalted butter
  • 1/2 cup light brown sugar, packed
  • 2 tablespoons maple syrup
  • 1 large egg
  • 1/2 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • pinch salt
  • 2.5 cups quick-cooking oats, gluten-free if desired
  • 1 teaspoon baking soda
  • optional: 3/4 cup semi-sweet chocolate chips

Instructions

  1. First, preheat the oven to 350ºF and spray a baking sheet with nonstick cooking spray.
  2. Next, combine melted butter and brown sugar until there are no lumps. Then, add maple syrup, egg, peanut butter, and vanilla and mix again.
  3. Add salt, quick-cooking oats, and baking soda and mix until everything is combined. Add in optional chocolate chips and mix again.
  4. Refrigerate dough for 20 minutes to set.
  5. Scoop 2 tablespoons of batter into your hands and form it into a ball. Place it onto the cookie sheet and slightly press down to form a cookie shape. The batter will feel a bit wet, but they will be so soft and chewy when done baking!* 
  6. Repeat the process above until you’ve fit 6  cookies on your baking sheet.
  7. Bake cookies at 350ºF for 11-14 minutes or until they begin to turn golden brown.

Tips & Notes

  • Cookie dough – the cookies will spread just a little bit when baking. If you don’t press them down, you will get dome-shaped cookies. 
  • If you use less than 2 tablespoons of dough, consider reducing your bake time by 1-2 minutes as your cookies will be smaller.
  • It might help to slightly moisten your hands before rolling the cookie dough and washing your hands in-between balls because the dough is pretty sticky. 
  • Nutrition information does not include chocolate chips.
