Peanutbutter-Chocolate Chip Brownies

I got this recipe from my dad, who got it from a lady he worked with. These blond "brownies" are soooo good, yet very simple to make!

2 cups sugar
1 cup melted butter
2/3 cup crunchy peanutbutter (creamy works, too)
4 eggs
2 tea. vanilla
2 1/2 cups flour
1 1/3 cups semi-sweet chips

Preheat oven to 350 degrees. Cream sugar, butter, peanutbutter, eggs and vanilla together until well-incorporated. Slowly add flour and mix well. Stir in chocolate chips. Spread batter into a 9"x13" baking pan. Bake for 25-30 minutes or until lightly browned.   

*You do not want to overcook! (They are wonderful served with vanilla ice cream!)
