Soft Peanut Butter Oatmeal Cookie Recipe

I’ve had this blog for over three years now and I’m still surprised at the questions I get. The two most common questions are “What do you do with all that food you make?” and the second is more of a statement, “You mean you take all the pictures on your site?”

I’m really surprised by the second comment. Readers think I buy stock photos. No. I make all the photos for my recipes. And I’ve worked really, really hard at developing my photography skills.

Soft Peanut Butter Oatmeal Cookie Recipe are heavenly cookies, full of chocolate and peanut butter.

You can go back and view some of my first posts and see how far I’ve come. Back then, all I knew about photography was turn on the camera, point and shoot… as evidenced in my pictures! #yikes

It’s all a work in progress. I find some foods easier to photograph than others. This cookie recipe was difficult. If you can’t tell by these photos, though, these cookies are AH-MAZING!!!

I filled them with chocolate! I put M&M candies and peanut butter cups in them. The dough was fantastic! It was so fantastic that I declared it a holiday! (You can follow me on Instagram for more laughs if you’d like.)

Soft Peanut Butter Oatmeal Cookie Recipe, there's nothing like homemade cookies and these are easy to make.

Soft Peanut Butter Oatmeal Cookie Recipe Tips

  • Use a spring release scoop to ensure all your cookies are the same size. This will allow them to cook more evenly and at the same time
  • Space the cookies 2 inches apart on an ungreased cookie sheet. This Soft Peanut Butter Oatmeal Cookie Recipe will not spread much, they make a thick cookie.
  • Allow the cookies to sit on the cookie sheet for 2 minutes before transferring them to a wire rack. This will allow the cookies to firm up a little and prevent them from breaking apart when moving them.
