Mix together R&H® Fudgie Brownie Mix according to the directions on the bag. Treat sheet trays with pan spray and line with parchment. Fill about ¾” full. Spread a thin layer or cream cheese filling over the brownie batter. Drag a knife or spatula through the pan to create a marbled design. Bake at 350°F for 40-50 minutes, or until a toothpick inserted in the center of the pan comes out clean. Cool brownies completely before cutting.
