MK’s Quadruple Chip Cookies

1 cup butter, softened to room temperature
3/4 cup granulated sugar
3/4 cup brown sugar
2 eggs

2 teaspoons white vinegar

1 tablespoon vanilla
3 cups all-purpose flour

3/4 teaspoon salt
1 teaspoon baking soda

1 tablespoon cornstarch
3/4 cups each milk chocolate, vanilla, butterscotch, and peanut butter chips

 Preheat oven to 350 degrees.  Beat the butter and both sugars until light and fluffy. Add eggs and beat until mixed.  Beat in vinegar and vanilla.  Mix together the flour, salt, baking soda, and cornstarch in a large bowl. Slowly add to batter and mix just until blended. Stir in chips by hand until mixed. 

 Drop dough onto parchment paper lined baking sheet by a 1-2 tablespoon measure cookie scoop.  Leave about 1-2 inches in between cookies.  Bake 10-12 minutes or until cookies are set and light golden brown around edges.  Cool on baking sheet for 2 minutes before transferring to a wire rack to cool completely.
