Mix together 20g peppermint flavouring and 5 460g Spred N Fill, reserve. Grind up candy canes, reserve. Mix brownie mix according to manufacturer directions. Line a half sheet tray with parchment paper and treat with pan spray. Deposit 1 135g batter, spread to edges, and bake at 350F/ 180 C until set. Let brownies cool completely then freeze. Unmold while frozen (this step is optional, but the brownies will both unmold and slice much easier from frozen) and top with 680g prepared peppermint crème. Melt fudge icing and pour a thin layer on top, sprinkle with ground candy canes before icing sets. Slice into 10x15 cm rectangles. Drizzle with warmed fudge icing and top with a mini candy cane.
