Preheat the oven to 350°F and line a baking sheet with parchment paper and set aside.
In a large mixing bowl, add cookie dough, M&M’s, peanuts, and raisins and mix together with a rubber spatula.
Using a medium cookie scoop, portion out cookie dough and place on the prepared baking pan leaving 2 inches between cookies.
Bake for 10-12 minutes until the edges begin to turn a golden brown.
Let the cookies cool on the baking sheet for 2-3 minutes, then transfer to a wire cooling rack.
Notes
You can add additional mix-ins such as coconut flakes, peanut butter chips, chocolate chips, and other dried fruits.No more than 2 cups of additional mix-ins should be incorporated into the dough as it won’t be able to hold it all in.
