Soften 1/2 cup of the butter.
Cream with the sugars.
Add egg and 1 1/2 teaspoons vanilla and beat until light and fluffy.

Divide dough in half and place each half between two sheets of wax paper.
Roll each half of dough out into a 12 inch by 10 inch rectangle.
Chill until almost firm, about 30 minutes.
Meanwhile melt chocolate chips and remaining 2 tbsp butter.

Spread 1/2 of mixture over each rectangle of dough.
Roll each rectangle up into a tight jelly roll and wrap in wax paper.

Cut each roll into 1/8 inch slices and place on a parchment lined baking sheet.
Bake at 350 F until lightly browned, about 7-10 minutes.
