Preheat oven to 350°F. Grease 9-inch square baking pan; line with enough parchment paper to hang over edges. Set aside.

In a heatproof bowl set over a saucepan of barely simmering water, melt butter and chopped chocolate, stirring occasionally. Remove from heat. Stir in sugar. Let it cool slightly.

Stir in eggs, one at a time, until well combined. Stir in vanilla. Fold in flour, mixing until incorporated. Fold in half of the Lay’s^® Classic Potato Chips.

Scrape batter into prepared pan; smooth top. Sprinkle with remaining chips and chocolate chips.

Bake for 30 to 35 minutes or until only a few moist crumbs adhere to a toothpick inserted into the center.

Let it cool completely in the pan or on a rack. Using parchment paper overhang as handles, transfer to a cutting board. Cut into squares.
