Add the butter and marshmallows to a microwave safe bowl.  Melt by microwaving in 30 second intervals and stir between each interval until fully melted.

Add the green gel food coloring to this mixture and stir until it’s a vibrant green color.

Gradually add in the rice Krispies cereal. Mix until completely coated.

Let the mixture cool slightly so you can handle the mixture with your hands.

Spray your hands with a non-stick cooking spray.  Then shape approximately 1/3 cup of the mixture into a cone (Christmas tree shape) and press the mixture firmly together.

Decorate with the decorating gel and mini M&Ms.

Top each one with a gold sprinkle and use the decorating gel to place a Reeses peanut butter cup on the bottom of each tree for the stems.

Let the trees sit at room temperature for 1-2 hours until the mixture and decorating gel is set.

Then they are ready to serve and enjoy!
