Mars Bars Squares

A couple of weeks ago, I was looking for a quick dessert to make for when my family came down to visit. My grandmother used to make this 'gourmet' twist on classic rice krispie bars for us as kids. It turns out that both my dad and my uncle, who were down with my grandmother for a visit, were a bit miffed that she had never made this for them as kids. They really only take about 2 minutes to make (and maybe less than that for them all to disappear off of the plate!).

4 Mars bars (I used dark chocolate Mars bars)
2 tbsp. butter
2 C rice krispies



8-inch square pan. Refrigerate.
