Preheat oven to 350°F. Line a 9x9-inch baking pan with foil or parchment paper and spray with nonstick cooking spray.

Stir together melted butter, oil, and sugar. Stir in cocoa, eggs, vanilla, and salt. Carefully stir in flour.

Spread brownie batter in prepared pan. Bake for 18-22 minutes or until a toothpick comes out clean.

While brownies are cooling, place the Nutter Butters and cream cheese in a food processor. Blend until smooth, scraping the bottom of the food processor if needed.

Press Nutter Butter mixture over cooled brownies.

Melt chocolate chips and peanut butter in microwave until smooth. Spread over Nutter Butter layer.

Let set at room temperature or chill before cutting for clean slices.
