Preheat oven to 350 degrees Fahrenheit. Line two 9×13-inch baking pans with Gefen Parchment Paper and set aside.

In a bowl, mix the oil, granulated sugar, brown sugar, and eggs until combined.

Add the flour, pudding mix, baking soda, and vanilla sugar. Mix until a smooth batter forms.

Stir in the chocolate chips and about two-thirds of the cookie pieces, reserving the remaining third for step 5.

Divide the batter evenly between the prepared pans, pressing into an even layer in each pan. Press the reserved cookie pieces on top.

Bake for 22–25 minutes, until light golden. Set aside to cool and cut each pan into 12 bars.
