Just a few more weeks until school starts. This year the kids aren’t going back until after Labor Day but the school supply list is out and we’ve already started our back-to-school shopping. I seem to be more excited about it than the kids :). We started by stocking up on lunch box and after school snack essentials at Harris Teeter, including everything we needed to make these super easy, totally delicious Trail Mix Cookies. Nothing gets kids excited for back-to-school like letting them help bake cookies :).

adding butter to peanut butter trail mix cookie mix

Along with all of the back-to-school staples like juice boxes and peanut butter and jelly I also let the kids pick out all of the mix-ins for a big batch of Trail Mix Cookies. We ended up with Harris Teeter semi sweet chocolate morsels and Harris Teeter mini marshmallows to go along with the Harris Teeter trail mix and oatmeal. These Trail Mix cookies are so easy to make and if you put them in an airtight container they last for days. They make the perfect lunch box dessert or after school snack!

M&M trail mix cookies

My daughter had so much fun helping me make them. The recipe is simple you cream the shortening, butter, sugar, peanut butter, and eggs together and then add the dry ingredients flour, oats, baking soda and baking powder mixing until everything is combined. Then come the mix-ins. You start with trail mix and oatmeal and then you can add anything else you like, dried fruit, candy, whatever you and your kids like. Mine chose chocolate chips and marshmallows because well, let’s just say they are their mother’s children :).

The cookie dough gets dropped onto a baking sheet and then into the oven they go baking at 375 degrees F for about 10 minutes or until they are light brown. Once they are out of the oven let them cool for a few minutes and then put them in an airtight container, or call the kids and sit down for cookies and milk like we did!
