 I got the recipe for these cookies from a friend over a decade ago. They have been a family favorite since then. We love that they are soft, chewy and crunchy and loaded with chocolate. They turn out perfect every time I make them, and they are always a hit.

Her recipe just called for chocolate chips, and I made them that way for years. Then one time I tried using M&M’s instead, and my kids loved them. Our favorite variation is to use half chocolate chips and half M&M’s. I don’t know anyone who can resist a cookie filled with M&M’s, do you?

So good! Make sure you have a tall glass of milk handy. They are perfect for dunking. 🙂

How to Make Peanut Butter Oatmeal Chocolate Chip Cookies

Ingredients you’ll need for these cookies:
  • butter
  • creamy peanut butter
  • white sugar
  • brown sugar
  • egg
  • vanilla extract
  • flour
  • old fashioned rolled oats
  • baking soda
  • baking powder
  • salt
  • chocolate chips
  • M&M’s (optional)
Cream together the butter, peanut butter, and sugars in a large bowl; beat in egg and vanilla. Stir in dry ingredients, chocolate chips, and M&M’s. Drop by spoonfuls onto silpat lined or lightly greased cookie sheets. Flatten slightly. Bake at 350° for about 8-9 minutes or till lightly browned on the edges. Cool for 2-3 minutes, then remove to cooling racks.
PRO TIP: To get pretty bakery style cookies, reserve some of the chocolate chips or M&M’s and place them on each cookie dough ball before popping the baking sheet into the oven.
Handy tools for making peanut butter cookies:
  • Adjustable Measuring Cup – so much easier than trying to scrape the last bit of peanut butter out of your measuring cup!
  • Cookie Scoop – I have a few of these in different sizes and brands. They are a great way to make sure all your cookies are the same size so that they will bake evenly.

What kind of oats should I use for these oatmeal cookies?

Regular old fashioned rolled oats work the best. Quick oats can be used in a pinch, but they tend to make the cookies more dry and crumbly. Instant oats are definitely not recommended.

What kind of peanut butter works best for peanut butter oatmeal cookies?

I like using Skippy or Jif brand. Creamy works better than crunchy. If you have to use crunchy peanut butter, add an extra tablespoon or two of peanut butter.

How to Store Peanut Butter Cookies

These cookies will keep for several days at room temperature if stored in an airtight container. They also freeze well. I just place them in freezer ziplock bags and they last in the freezer for up to six months. 

Can I freeze this cookie dough?

Although I am a huge fan of rolling cookie dough into balls and freezing it, I’m not a fan of freezing oatmeal cookie dough. I find that the oats absorb moisture, making the cookies turn out a bit dry. For this recipe I recommend freezing the cookies instead of the dough.
