Ingredients
For the Cookie Dough
-
1 cup unsalted butter, softened
-
¾ cup granulated sugar
-
¾ cup light brown sugar, packed
-
2 large eggs
-
1 tablespoon vanilla extract
-
1 (3.4 oz) box instant banana pudding mix
-
2 ¼ cups all-purpose flour
-
1 teaspoon baking soda
-
½ teaspoon baking powder
-
½ teaspoon salt
-
1 ½ cups white chocolate chips
-
1 ½ cups crushed Nilla wafers (plus extra for topping)
Instructions
In a medium bowl, whisk together flour, baking soda, baking powder, salt, and the banana pudding mix. Set aside.
In a large mixing bowl, beat softened butter with brown sugar and granulated sugar until creamy and fluffy, about 2–3 minutes.
Beat in the eggs one at a time, then add vanilla extract. Scrape down the sides of the bowl to make sure the mixture is well combined.
Gradually mix the dry ingredients into the butter mixture. Be careful not to overmix—stop once the flour disappears in the dough.
Fold in white chocolate chips and crushed Nilla wafers. The dough will be thick and flavorful.
Cover the bowl and refrigerate the dough for 30 minutes. This helps the cookies stay thick and prevents spreading.
Preheat the oven to 350°F (175°C). Scoop dough into 2-tablespoon balls onto a parchment-lined baking sheet.
Bake 10–12 minutes, until edges are set but centers look slightly soft.
Add extra crushed Nilla wafers on top while warm. Allow cookies to cool on the baking sheet for 5 minutes before transferring to a rack.
Notes
Banana pudding mix is the secret ingredient—it adds moisture, flavor, and softness. Always use instant pudding mix, not cook-and-serve. Chilling the dough is essential for thick cookies with bakery-style texture.
