Peanut Butter Brownies

Going through our bar recipe files makes me hungry for some of the "old standbys" which we haven’t used for some time.  Here is one that easily makes a big batch (it makes two 9x13 pans).

Blend thoroughly:

4 eggs
2 cups white sugar
1 cup brown sugar
2/3 cup peanut butter
1/3 cup shortening
2 tsp. vanilla

Sift and add to mixture to make smooth batter:

2 2/3 cups flour
1 Tbsp. baking powder
1 tsp. salt

Add:

1/2 cup chocolate chips
1/3 cup nuts

Bake in 2 9x13 pans at 350ºF for 30 minutes.
