If you have a box of brownie mix lying around, you’re in for a treat! I absolutely love making brownie cookies from a box mix. They’re so easy and delicious! Today, I decided to switch things up and added some Reese’s chocolate bars to the mix and a drizzle of creamy peanut butter on top once out of the oven. The combination of fudgy brownie texture with the creamy peanut butter flavor is simply irresistible.
