Step 1: Cream the butter, granulated sugar, and brown sugar until light and fluffy. Add eggs one at a time, then stir in vanilla and mashed bananas.
Step 2: In a separate bowl, whisk together flour, baking soda, and pudding mix. Gradually add to wet ingredients and mix until just combined. Fold in white chocolate chips and crushed vanilla wafers.
Step 3: Drop rounded tablespoons of dough onto a parchment-lined baking sheet, leaving space between each cookie.
Step 4: Preheat oven to 350°F (175°C) and bake for 10-12 minutes until edges are golden and centers are soft.
Step 5: Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
