melt butter in a large sauce non stick pan over low-medium heat. add the bag of marshmallows and stir until completely mixed and smooth. Stir over the 6 cups of rice krispies. Mix extremely well and quickly.
take a handful of the mixture and press into a cupcake pan molding a cup shape. I use a plastic easter egg to press into the middle to smooth it out and make it deeper than my fingers can.
Let these harden for an hour. Over night is ok if you have the time. MEAN WHILE........
In the cleane,d same non stick sauce pan, add the peanut butter and chocolate chips, over low to medium heat and stir until conbined and melted smooth
mix in the walnuts, raisins and mini marshmallows. Stir until covered and coated well. Using a regular eating table spoon, scoop enough of the mixture into the rice krispie cups to fill without pouring over the sides.
My family can never wait for these to harden naturally so I put them in the fridge for about 1 hour and VIOLA!! poop in a cup!
