Butter a 13x9 inch baking pan, or use non-stick spray; set aside.
In a large saucepan, or Dutch oven pot, melt the butter and 7 cups of the mini marshmallows over medium heat, until melted - stirring the whole time, so that the mixture doesn't stick or burn.
Once the marshmallows are completely melted add in the lemon extract and a few drops of pink food coloring. Use only a few drops at a time to get the color you want.
Add the cereal and mix together. Once the cereal is incorporated, add the remaining 2 cups of mini marshmallows and combine.
Spread mixture into prepared pan and lightly pat down. Top with sprinkles and again, lightly press down. Allow mixture to cool completely before cutting into squares. You can also put the treats into the refrigerator for 30 minutes to cool quicker.
