Mint Chocolate Dessert Cups

In a small bowl, combine mint chocolate sandwich cookie crumbs and melted butter. Mix to combine.
Portion the crumbs into 28 2-ounce plastic cups using a small cookie scoop or spoon. Use one of the plastic cups to press the crumbs into the bottom of the cup.
In another mixing bowl, combine room temperature cream cheese and granulated sugar. Cream together using an electric hand mixer on medium speed until combined and smooth.
Add mint extract, heavy whipping cream, and one drop of green gel food coloring if desired. Whip on medium-high speed until light and fluffy.
Fill a piping bag with the mint cream. Pipe the mixture into the cups until about 3/4 full.
To make the chocolate ganache, combine chocolate chips and heavy cream in a microwave-safe bowl and heat for 30 seconds. Mix until smooth. Transfer to a squeeze bottle or piping bag.
Drizzle the chocolate ganache over the mint cream. Sprinkle with additional mint chocolate cookie crumbs.
Seal the cups with a lid and chill. The cups can be served immediately or stored in the refrigerator for 2 to 3 days.
