1 cup butter, softened
3/4 cup turbinado sugar
2 cups flour
1 cup premium dark chocolate chips
1 tablespoon Madagascar vanilla
Whisk the sugar into the butter until it is creamy. Add half the flour gently using a wooden spoon until combined. Pour the vanilla over the chocolate chips and stir, then add to the batter and fold in. Add the remaining flour and blend.
Bake in a well-buttered 9x12 pan at 350 degrees for 12-15 minutes. It's done when the top is starting to firm and the edges are golden, pulling away a bit from the sides of the pan. Remove and scoreline bars, then let cool before removing.
