Peanut Butter Rice Krispie Squares

Thats right, a recipe! For the past couple of weeks I had this incredible craving for mars bar slice. I made it, loved it, and felt very ill. I then had to work out what to do with the remaining box of rice bubbles. After some experimentation, we have..

Ingredients:
-2 cups rice bubbles
-1 tablespoon peanut butter
-1 teaspoon margerine/butter
-100g marshmallows

Directions:
Grease and line tin (20cm square is a little big but ok)
Microwave first 3 ingredients for about 10 sec, till marshmallows puff up.
Mix in rice bubbles and put mixture into tin. Flatten.
Cool in fridge, then cut into squares and put into an airtight container.

Obviously you could make more, this is is about the minimum worth making. The basic idesa behind these sorts of recipes seems to be melting caramel/chocolate/marshmallow with a small amount of nicely flavoured fat (generally butter), then mixing in crunchy carbohydrates like cereal or biscuits. Next idea is melting jersey caramels and mixing with biscuits..mmm...
