Prepare both cake mixes, according to directions on box. Pour batter into two standard sized bundt cake pans and bake according to package directions. Let cool completely. Set aside.

In a large bowl, whip frosting until light and fluffy, using an electric mixer. Use the two food colorings to dye frosting deep orange color. Place one bundt cake, round part down, on a serving platter. Place the second bundt cake, flat side down, on top of the first cake to resemble a pumpkin shape. Using a cake spatula, spread the orange frosting over the top and sides of the cake. Using your favorite candies, design the eyes, nose and mouth of the pumpkin. Garnish with flowers and candies.
