Frost it one more time so that it looks nice and clean. Basically, we just don't want to see crumbs. Also, get it as smooth as you can manage. Now things get messy! Grease your counters WELL. Be liberal with your amount of shortening you spread around. Be sure to get it on your hands and wrists as well. I know it feels weird! Just go with it and you'll have nice and soft hands when you're finished. :)

Thank you for the instructions! Mine came out pretty well and the kids loved it. Here's what I learned: Melt your marshmallows and and about 2 tbs of water in a large, microwave safe bowl. Put the bowl in the microwave for 30 second intervals. After every 30 seconds, open microwave and stir the mixture until it is fully melted. This should take about 2.5 minutes. When melted, pour about 3/4 of the powdered sugar on top of the marshmallow. tablespoons of water This isn't exact. You may need more or less. You just want your fondant to be workable.First thing you need to decide is how your cube is going to sit. I prefer the "in progress" look of the cube, but you can have it be a correctly aligned cube if you so desire. :)

A bag of good quality mini marshmallows. I say good quality because I have used discount marshmallows that refused to melt!Make the marshmallow fondant: In a large microwave-safe bowl, combine the marshmallows and water. Microwave on medium power for 2-3 minutes, stirring every 30 seconds, until the marshmallows are completely melted. Add the softened butter and use a silicone spatula to stir until combined. First, you need to chose a type of cake to bake. It really doesn't have to be any particular kind for this cake. Use your favorite recipe or box mix and double it. The next step is to cover your cake in a "crumb coat" with your frosting. Don't feel bad when this looks ugly. That's why it's a crumb coat. Just make sure to evenly coat your cube and let dry before you move on to the next coat of frosting. Fondant- I highly recommend making your own marshmallow fondant. It's simply, delicious, and looks very professional
