Peanut Butter-Chocolate Fudge Brownie

 Prepare the chocolate brownie fudge mix according to package directions. Set aside.

In a saucepan, gently melt 3 tablespoons peanut butter with 1 tablespoon chocolate chips and 1/2 tablespoon butter. Add to brownie mixture until just combined.

Pour mixture in a lined 9-by-5-inch baking pan.

Melt remaining peanut butter and drizzle over brownie mixture.

 Bake in a preheated oven at 350F for 20 minutes or until it has a crust but the middle seems slightly uncooked.

Melt remaining chocolate and drizzle over the brownie. Cool before cutting into squares or bars.
