Chewy Peanut Butter Brownies

Step 1

Preheat oven to 350 degrees F (175 degrees C ). Grease a 9x9 inch baking pan.

Step 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.

Step 3

Bake for 30 to 35 minutes in preheated oven, or until the top springs back when touched. Cool, and cut into 16 squares.
