These things are huge and full of all kinds of goodies!
 
I start with a basic Rice Krispie square recipe and then pile on the extras.  It's got peanuts.  It's got chocolate chips.  It's got toffee bits.  It's got pretzel pieces.  
 
So much stuff, in fact, that it fills an entire 9X13 pan.  I mean all the way to the top:  2 inches tall.
 
Easily customizeable if you'd like.  I can substitute things like M and M's, peanut butter chips, potato chips, other kinds of cereals, Rice Krispie treats are great that way.  
 
The full pan, the crowd-sized batch, all 3 pounds of it, is $30 cut to whatever size you'd like.  I can also do a half recipe which would fit in an 8 x 8 pan (though not as tall as a 9 x 13) for $15, again cut however you'd like.  
 
If you aren't that hungry, I can sell an approximately 3" x 2" block (about 6 oz) block for $4 each.
 
p.s. this is an easy one to make gluten free too.  I can just sub in gluten free pretzels.
