Scale and mix R&H® Fudgey Brownie Mix according to bag directions. Incorporate 12% pecans into batter before baking. Line a half sheet tray with parchment paper and treat with pan spray. Deposit 3 pounds batter, spread to edges, and bake at 350F until set. Let brownies cool completely, spread with chocolate fudge icing, then freeze. Unmold and cut while frozen (this step is optional, but the brownies will both unmold and slice much easier from frozen). Decorate by piping small squiggles of caramel fudge icing and cream cheese icing.
