Lightly coat a 9x5" loaf pan with cooking spray. In a large saucepan, melt 3 Tbsp. butter over medium heat. Add in 4 cups marshmallows. Stir until combined. Pull pan off heat and mix in rice krispies until throughly covered with melted marshamllows. Immediately transfer to prepared pan and press firmly (I used a small spatula) to get an even layer on the bottom.
Rinse saucepan and repeat the first step: melt 3 Tbsp. butter, add in 4 cups marshmallows. Stir in orange food coloring and then rice krispies treats. When combined thoroughly, pour into pan over the first layer of cereal treats. Pat in firmly using buttered fingers or a small spatula.
Repeat the step one more time, melting the butter, adding in marshmallows and this time yellow food coloring. Stir in rice krispies and then pour and pat into the pan.
Let set for 2 hours, or until completely set. Run a knife around the outside of the pan and invert the loaf onto a cutting board. With a serrated knife, cut into 10 slices and then cut each slice in half crosswise.
Gently mold each square into a candy corn shape. Serve & enjoy!
