Shellie's Special K Treats

6 c. Special K cereal (you can also use corn flakes)
1 c. pecans
2 cubes butter
1 c. brown sugar
3 or more cups of marshmallows ( I think I use one pkg)

Melt marshmallows, butter and brown sugar in a big bowl in the microwave. Add the rest and make to the consistency of rice krispie treats.
