Chocolate Peanut Butter Chunk Cookies

Peanut Butter Chocolate Cookies
Easy chocolate peanut butter chunk cookies made with chocolate cake mix, a healthy dose of peanut butter, and studded with peanut butter chips.

Great things about these chocolate peanut butter chunk cookies:

  • I love that these cookies come together quickly and easily in one bowl with one spoon.  You can whip up a batch when you have unexpected guess or you for got you were supposed to bring treats to work tomorrow.
  • There are only 5 ingredients, because we use the chocolate cake mix to provide us with the flour and sugar and cocoa powder in one convenient package.
  • Because of the cake mix, they are moist and chewy cookies, a little bit like a cross between a cupcake and a traditional cookie.
  • They are sort of an inside out version of these peanut butter chocolate chip cookies.

Notes about chocolate cookies:

In my experience, it’s tricky to tell when a chocolate cookie is finished baking.  I typically rely on the browning of the bottom of the cookies to help determine when they are done, but that does not work for a chocolate cookie.  

For chocolate cookies, I rely on the look of the top, you want the top of the cookie to look mostly dry and a little bit cracked.  You don’t want it to be shiny on top.
