Add the cookie mix and pudding mix to the bowl of a stand mixer. Blend together until evenly combined.
1 17.9 oz pkg snickerdoodle cookie mix, 1 3.4 oz pkg banana cream instant pudding mix
Add the butter, mashed banana, and egg then mix (starting on low, then gradually increasing the speed) until a thick dough comes together- scraping down the sides of the bowl, as needed.
4 tbsp salted butter, 1 - 1 1/2 overly ripe banana, 1 large egg
Add the wafers and chocolate chips to the dough, and fold in with a sturdy spatula until evenly incorporated.
1 cup lightly crushed vanilla wafers, 1 cup white chocolate chips
Line two cookies sheets with parchment paper. Using a medium ( 1 1/2") cookie scoop, scoop out 12 balls of dough and arrange them on one of the sheets, evenly spaced out. Scoop the remaining dough and arrange in evenly spaced rows on the second baking sheet.
Bake at 350° for 10-12 minutes, just until the cookies are golden brown and the edges are set.
Remove the cookies from the oven, and let them cool.
Serve and enjoy!
