Spray a non stick cooking spray on a rectangle baking pan and set aside.

Measure out your rice crispy cereal and set aside.  I prefer to melt the marshmallows using the stove top method over medium heat.  I've seen many photo fails with the microwave method.

Start by melting the butter.

Once the butter is melted, add the marshmallows.  Stir repeatedly so you don't burn them.

Once completely melted, I immediately add the Rice Crispy cereal and stir.

After the melted marshmallow is completely mixed in I dump the hot ingredients into the baking pan.  I grab a little bit of butter and rub it on my clean hands.  By doing this I never worry about the treats sticking to my fingers.

Next, start shaping the rice crispy treats in the pan by spreading it out and pressing down.  I add more butter to my hands if needed.
