Step 1: Heat oven to 350°F. Grease a 9 x 13 pan with cooking spray.
Step 2: Place butter in a saucepan; heat over medium heat until butter is melted. Remove from heat and stir in sugar and vanilla extract. Add eggs, one at a time beating well after each egg addition. Add cocoa; stir until well blended. Add flour, baking powder and salt; stir until combined. Mix in chopped Snickers.
Step 3: Transfer to pan. Drop dollops of peanut butter over the batter. Using a knife, swirl peanut butter into brownies.
Step 4: Bake for 35-40 minutes or until brownies begin to pull away from sides of pan and a toothpick inserted in the middle comes out clean. Cool brownies completely in pan on a wire rack then slice into squares.
