If you are looking for oatmeal cookies that are soft and chewy with a sweet and salty peanut butter flavor, these peanut butter oatmeal cookies are the perfect cookie. Homemade cookie fans are going to love this recipe because it blends 3 things we all love so much: hearty oatmeal, creamy peanut butter, and of course, chocolate!

Is your sweet tooth still craving more peanut butter? We’ve got you covered with more delicious treats including our No-Bake Peanut Butter Bars and Old Fashioned Peanut Butter Fudge recipes.

PEANUT BUTTER OATMEAL COOKIES INGREDIENTS

You’ll need:

  • ½ cup butter
  • ½ cup peanut butter
  • ½ cup brown sugar
  • ½ cup of granulated sugar
  • 1 egg
  • 1½ teaspoons vanilla extract
  • 1 cup all-purpose flour
  • 1 cup quick cook oats
  • ½ teaspoon baking soda
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • 1 bag semi-sweet chocolate chips

SUBSTITUTIONS AND ADDITIONS

BUTTER: Cutting out butter? While it may cause a change in flavor and make your recipe a bit ‘coconut-y’, coconut oil can be used as a 1:1 substitute for butter.

EGG: If you’re looking to replace the egg, using ¼ cup (approximately 65 grams) of applesauce or ¼ cup of pureed bananas can replace a single egg. 

CHOCOLATE CHIPS: Try dark or white chocolate chips or even peanut butter chips instead of your semi-sweet chocolate chips to change the flavor of these easy cookies.

PEANUT BUTTER: We used smooth peanut butter, but if you prefer crunchy peanut butter, you could use that as well.

OATS: We recommend using quick oats rather than old-fashioned oats in this recipe.

HOW TO MAKE THIS PEANUT BUTTER OATMEAL COOKIES RECIPE

STEP ONE: Preheat oven to 375°F and line a cookie sheet with parchment paper.

STEP TWO: In a large bowl, with a hand mixer or stand mixer, cream together butter and both sugars until the mixture is fluffy.

STEP THREE: Add in your single egg and vanilla and mix until there are no lumps.

STEP FOUR: Put your dry ingredients together in a separate medium bowl. Mix ingredients together.

PRO TIP:

Sift your flour and other dry ingredients making sure to get rid of any lumps.

STEP FIVE: Slowly add the dry ingredients to the wet ingredients and mix until the dough comes together.

STEP SIX: Stir in the chocolate chips. 

PRO TIP:

Leave about 1½ to 2 inches of space between cookies on the sheet, keeping in mind that they’ll expand quite a bit.

STEP SEVEN: Roll spoonfuls of dough into balls and place dough ball on the prepared baking sheet.

STEP EIGHT: Bake cookies for 10 to 12 minutes. Let cool on a wire rack.

PRO TIP:

To quickly judge if your cookies are ready, remove the cookie sheet from the oven a bit, and push at the sides of a cookie lightly with either a spatula or carefully your finger. If the edge stays firm and doesn’t fall inwards, then your cookies are done.

HOW TO SERVE

Peanut butter fans will enjoy these chewy peanut butter oatmeal cookies. The best way to serve these treats is with a cold glass of milk, chocolate milkshake, or warm whipped hot chocolate.

FREQUENTLY ASKED QUESTIONS

Can I freeze these cookies?

This easy recipe can be frozen for up to three months in an airtight container.

Can I use old-fashioned oats?

The smaller pieces of quick oats are best in these cookies but if you only have old-fashioned oats, just pulse them in a food processor a few times to make the pieces a bit smaller.

Should I use creamy or crunchy peanut butter?

We used creamy peanut butter but you can use crunchy peanut butter if you’d like.

    Made these for the first time today…YUM! They are the perfect combination of crunchy on the outside and soft on the inside. I used mini chocolate chips and made them bite sized. They will be the perfect treat in the kids lunch boxes tomorrow.
