I made this for a football party we had with some friends. I used my 10 & 4 football pan and doubled the original rice crispy recipe. I added brown gel color to the marshmallows to get the football color. You could use cocoa crisps but I think that would be way too sweet.
I can't believe how many times I have used this pan. I definitely recommend getting this one. You can also bake bread in it to make a fun sandwich.
