Chewy Peanut Butter Brownies

"These brownies have been a favorite in my family since I was a small child. Because they're so popular, I usually double the recipe. Great with chocolate frosting!"

Make 1 (9x9 inch) pan.

Ingredients :

• 1/2 cup peanut butter
• 1/3 cup margarine, softened
• 2/3 cup white sugar
• 1/2 cup packed brown sugar
• 2 egg
• 1/2 teaspoon vanilla extract
• 1 cup all-purpose flour
• 1 teaspoon baking powder
• 1/4 teaspoon salt

Directions :

1. Preheat oven to 350 degrees F (175 degrees C ). Grease a 9x9 inch baking pan.
2. In a medium bowl, cream together peanut butter and margarine. Gradually blend in the brown sugar, white sugar, eggs, and vanilla; mix until fluffy. Combine flour, baking powder, and salt; stir into the peanut butter mixture until well blended.
3. Bake for 30 to 35 minutes in preheated oven, or until the top springs back when touched. Cool, and cut into 16 squares.
