Peanut Butter Swirl Bars - cooking recipe

Ingredients

1/2 cup crunchy peanut butter (we like Jiff)
1/3 cup softened margarine
3/4 cup packed brown sugar
3/4 cup sugar
2 eggs
2 teaspoons pure vanilla extract
1 cup flour
1 teaspoon baking powder
1/4 teaspoon salt
1 cup chocolate chips (or to taste)

Preparation

Preheat oven to 350 degrees.
Cream together peanut butter, margarine, brown and white sugar.
Add eggs and vanilla.
Sift or mix together flour, baking powder and salt and add to mixture.
Spread in a greased 9x13 pan and sprinkle chocolate chips over top.
Bake for 3 minutes.
Remove pan and swirl melted chocolate chips through peanut butter mixture with a butter knife. We make it look like a huge serpentine snake going through the mixture, as opposed to circle swirls.
Return pan to oven and bake 15 minutes more.
