Chocolate-Peanut Butter Trifle I didn't find this kind of cookie mix at the store so I tweaked it a little. I used Rainbow Chip Cookie mix (the regular cookies with mini M&M's) and added a little cocoa to them to darken the cookies. I forgot until I got to the step that the recipe called for a hand mixer. We don't have one so I beat the cream with a couple of forks for awhile. Instead of peanuts I cut up a few bite size Resees and Hershey's. It turned out to be amazing!
