Cut a Carrot Sheet Cake into 3 square cuts, graduating in size by about 1/2 inch. Place the largest square on the bottom of a plate or shallow bowl. Add the following layers by rotating 1/4 turn, with the result resembling a Christmas Tree. Use a frill pick to secure a Maraschino cherry on top. Drizzle raspberry and caramel dessert sauce around the cake like ribbons and ornaments, then garnish with sifted powdered sugar to simulate snow. Place holiday candies as presents at the base, if desired.
