1 C. Butter, Softened
3 C. Brown Sugar
3 C. Flour
2 tsp. Vanilla
1 tsp. Baking Powder
1 tsp. Salt
1 C. Chocolate Chips
1. Mix all ingredients except chocolate chips.
2. Spread in a 10x15 jelly roll pan.
3. Sprinkle chocolate chips on top.
4. Bake 25-30 minutes at 350 degrees. The middle takes a while to set and stays a bit gooey but honestly it's my favorite part of these bars!!!
