I wanted to make a cute back to school treat, but couldn't find anything I liked. I thought the school bus idea was cute, but had only seen it with a twinkie, and that just seemed gross to me. So, I decided to try it with Rice Krispies treats.
I started by making a double batch of the recipe found on the side of the Rice Krispies box and pressing it into a 9x13 glass pan. I wanted it to be thick, and it didn't look like it would fit at first, but it did. After I let the treats cool, I cut them into 16 rectangles, took a few out at a time, put them on their sides, and cut a little out of each one to make the bus. I bought the betty crocker dark chocolate brownie topper to help with decorating. I also bought the plastic screw on decorating tips so I could have a thin line. That stuff dries pretty hard, which I was not aware of, but it worked well because it was thick and I didn't have to make my own frosting.
After trial and error and fingers in frosting, I discovered the following order works best for avoiding messing up the windows:
1 - put on the wheels - I used the mini fudge stripes that come in 100 calorie packs for the wheels, and used toothpicks and the frosting to try and get them to stay on. Later when the icing had dried, I found I could take out the toothpicks and they would stay. Maybe mini oreos would have worked better. I don't know. I might try something different next time.
2 - put on the lights - I cut a red and a yellow jelly belly in half to make the lights and secured them with frosting. I tried pushing them into the treat the first couple of times, but that didn't work too well.
(Don't worry, I made her wash her hands twice with soap before continuing to help)
3 - draw the front window and put in the bear driver - We cut the legs off of some mini teddy grahams for the driver and attached with frosting.
4 - draw all the other windows and black lines on the sides
Voila! School buses for sharing. At first we tried putting bears in all the windows as well, but my daughter got tired of cutting off the legs of the bears and we decided it was easier to just have an empty school bus. We found that we could do about 8 at a time assembly line style.
When we were done, I let the kids create their own masterpieces with the cut out leftovers of rice krispies treats and some candy and frosting.
