Caramel Chocolate Blondie Bars

Preheat oven to 350 degrees. Grease 7x11 glass baking dish. If you only have non-stick reduce heat to 325. Combine first three ingredients, set aside. In a large mixing bowl, beat butter and sugars until smooth, add eggs and vanilla until blended. Gradually add the dry mixture and chocolate chunks. Stir until well blended. Spread evenly into prepared pan. Drizzle caramel topping in criss-cross fashion across the batter. Swirl with a knife if needed. Bake for approx 20-23 minutes or until golden brown.
