Peanut Butter Streusel Brownies

Ingredients

4 (1-oz.) unsweetened chocolate baking squares 

3/4 cup butter

1 1/2 cups granulated sugar

1/2 cup firmly packed brown sugar

3 large eggs

1 cup all-purpose flour

1 teaspoon vanilla extract

1/8 teaspoon salt

1/2 cup all-purpose flour

2 tablespoons light brown sugar

2 tablespoons granulated sugar

1/3 cup chunky peanut butter

2 tablespoons melted butter

1/8 teaspoon salt

 Preparation

1. Preheat oven to 350°. Line bottom and sides of an 8-inch pan with aluminum foil, allowing 2 to 3 inches to extend over sides; lightly grease foil. 

2. Microwave chocolate squares and 3/4 cup butter in a large microwave-safe bowl at HIGH 1 1/2 to 2 minutes or until melted and smooth, stirring at 30-second intervals. Whisk in 1 1/2 cups granulated and 1/2 cup brown sugars. Add eggs, 1 at a time, whisking just until blended after each addition. Whisk in 1 cup flour, vanilla, and 1/8 teaspoon salt. 

3. Pour mixture into prepared pan. 

4. Stir together 1/2 cup flour, 2 Tbsp. brown sugar, 2 Tbsp. granulated sugar, peanut butter, 2 Tbsp. melted butter, and 1/8 tsp. salt until blended and crumbly. Sprinkle peanut butter mixture over batter. 

5. Bake at 350° for 50 to 54 minutes or until a wooden pick inserted in center comes out with a few moist crumbs. Cool completely on a wire rack (about 1 hour). Lift brownies from pan, using foil sides as handles. Gently remove foil, and cut brownies into 16 squares.
