Chocolate Bliss Peanut Butter Brownies

1 package (8 squares) semisweet baking chocolate
3/4 cup firmly packed brown sugar
1/2 cup peanut butter
1/4 cup (1/2 stick) butter or margarine, softened
2 eggs
1 teaspoon vanilla extract
1/2 cup flour
1/4 teaspoon baking powder
1 1/2 cups semisweet chocolate chunks
2 cups peanuts, chopped

Heat oven to 350 degrees F.

Microwave chocolate squares in large microwavable bowl on HIGH for two minutes, stirring halfway through heating time. Stir until chocolate is completely melted and smooth. Stir in sugar, peanut butter, butter eggs and vanilla extract with wooden spoons until blended. Stir in flour and baking powder. Stir in chopped chocolate and peanuts. Drop by scant 1/4 cupsful onto ungreased cookie sheets.

Bake 13 to 14 minutes or until cookies are puffed and feel set to the touch. Cool on cookie sheets one minute. Remove to wire racks and cool completely. Makes about 18 large cookies.

If omitting peanuts, increase flour to 3/4 cup to prevent spreading. Makes about 15 large cookies.
