Prepare an 8x10 baking dish with non-stick spray or butter. Mix together the carrot cake ingredients in a large mixing bowl. Use your hand mixer to beat together for about 2 minutes. Add the batter to the deep baking pan and bake for 25-30 minutes, until a toothpick comes out clean. Remove the cake from the oven and allow it to cool for about 30 minutes.
Once the cake has cooled, add it to a large mixing bowl and crumble using your hands or a spoon (clean hands work best!). Add the frosting and mix into the crumbles until it becomes a dough-like consistency.
Place a piece of wax paper on a baking sheet. Take about 1 tablespoon of the cake mixture and roll it into a ball between your hands. TIP: To keep the mixture from sticking to your hands, spray them with non-stick spray or place a little vegetable oil on your hands before rolling the balls. Place each ball on the wax paper. Once all of the balls are rolled, place the baking sheet in the fridge for 1-2 hours to chill.
Before removing the cake bites from the fridge, melt the almond bark. You can melt over the stove using a double boiler or you can melt in the microwave in a microwave-safe bowl. Cook in the microwave for 1 minute, remove the bowl, and stir. Continue to melt at 30-second intervals until the bark has melted completely. Add the shortening or oil and stir in.
Remove the cake bites from the fridge and dip each one in the almond bark, coating completely. Remove the ball using a spoon and tap on the edge of the bowl to remove excess bark. Place the ball back onto the wax paper to cool/set. Once you have 6 bites coated, take the bunny feet candy and place two on each ball. You want to do this before the coating completely sets or they will not stick (see notes on how to attach the feet if this happens). Once all of the bunny feet have been stuck to the cake bites, continue coating the remainder cake bites.
Take each of the marshmallows that have been cut in half, dip the end in the leftover almond bark and stick it to each ball above the feet.
Make the edible grass by placing the shredded coconut into a small mixing bowl. Add a few drops of green food coloring and mix immediately using a fork or a spoon. Continuing stirring until all of the green food coloring has been distributed on the coconut. This will take a minute or two. Add more coloring if need, a few drops at a time. A little goes a long way.
Place one bunny in a cupcake liner. Place some of the green coconut grass around the edges. If you are using a candy carrot, add that to the grass. Enjoy!
