chewy peanut butter brownies

Josh made these yesterday and they are yummy. We even had fun taking pictures. They are from the "3 books in 1" recipe book that Joy gave us for Christmas (pg2).

Chewy Peanut Butter Brownies
3/4 c. (1 1/2 sticks) butter, melted
3/4 c. creamy peanut butter
1 3/4 c. sugar
2 tsp vanilla
4 eggs, lightly beaten
1 1/4 c. all-purpose flour
1/2 tsp baking powder
1/4 tsp salt
1/4 c. unsweetened cocoa powder

1. Preheat oven to 350F. Grease 13*9 inch baking pan.
2. Combine butter and peanut butter in large bowl; mix well. Stir in sugar and vanilla. Add eggs; beat until well blended. Stir in flour, baking powder and salt just until blended. Remove 1 3/4 cups batter into small bowl; stir cocoa into remaining batter.
3. Spread cocoa batter evenly in bottom of prepared pan. Top with remaining 1 3/4 cups of reserved batter. Bake 30 minutes or until edges begin to pull away from sides of pan. Cool completely in pan on wire rack; cut into bars.
