Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, cream together softened butter, brown sugar, and white sugar for 2-3 minutes until light and fluffy.

Beat in eggs and vanilla extract until just combined, ensuring a smooth blend.

In another bowl, whisk together flour, banana pudding mix, and baking soda before gradually combining with the wet mixture.

Gently fold in crushed Nilla wafers and white chocolate chips.

Scoop dough balls onto prepared sheets, spaced about 2 inches apart, and chill in the refrigerator for 20-30 minutes.

Bake for 9-11 minutes until the edges are golden brown and the centers are soft.

Cool on the baking sheet for about 5 minutes before transferring to a wire rack.
