A classic, with a twist.

In a large pot set over a medium heat add 180g marshmallows, 3 tbs margarine, 3 tbs peanut butter, 2 tbs agave syrup, 2 tbs cocoa powder, and stir constantly till the marshmallows are melted and everything is well-combined. 

Turn off the heat and add 4 cups Rice Krispies. Stir well to evenly coat the grains and then pour into a large square or rectangular baking dish which has been lined with a non-stick liner.

Cool and then cut into squares.
