In a heavy saucepan, bring cream and corn syrup to boil. Add butter and invert sugar. Cool to at least 98°. Melt chocolate. Blend with a whisk until a smooth consistency is reached. Stir in cinnamon oil.
CUT GANACHE:
Spread the mixture into a 9" x 9" pan lined with parchment paper, keeping the top as smooth as possible. Chill for several hours in the refrigerator. Remove from pan and cut into squares using a bench cutter, pizza cutter or a cut shapes using a cookie cutter. Dip into melted candy coating or melted and tempered chocolate. The squares may be kept in the refrigerator for ease of dipping. Immediately after dipping, place a chocolate transfer sheet square on the top, texture side down. Allow to set for several minutes, then peel transfer sheet off.
