My friend Lisa D. called a few months ago and asked me to make her wedding cake. There was only one catch...she wanted it to be made of Rice Krispie Treats. 
She wasn't too particular about the design. Her colors were navy blue and yellow (go Orem Tigers!!!). She wanted fresh flowers and multiple tiers. So I drew up a little sketch and she approved.
The next step was to try to visualize how it would all look. I couldn't decide how tall to make the layers but finally decided on about 3.5" each.
My tower fell down very soon after i took that last picture!!!
I figured it would take about 4 batches of RK Treats for the whole cake...boy, was I wrong!!!
It took 7 batches! That's 7 lbs. of marshmallows, 1 lb of butter, and 49 cups of Rice Krispies. (I had to run to the store at 9pm just to get a couple more bags of marshmallows!)
Here are the RK Treat "cakes" all finished. My cake pans are only 2" high so I had to use cardboard collars to get the cakes as tall as I wanted.
Gratefully, the flowers arrived on time at the flower store. I could barely fit them in my tiny fridge for their overnight stay! 
It's amazing what a little ribbon and a few flowers can do to make RK Treats look quite elegant!
Congratulations Lisa and Spencer!!!
