Prep Your Sheet: Line a baking sheet with parchment paper and set it aside.
Make the Mint Base: In a medium bowl, combine the softened cream cheese with Β½ cup of the powdered sweetener, mint extract, and green food coloring. Mix well.
Add More Sweetness: Gradually add the remaining powdered sweetener, about Β½ cup at a time, mixing until everything is well combined and forms a dough-like consistency. You can use a mixer, but many find mixing by hand works best to avoid overbeating.
Form the Buttons: Scoop out about a teaspoon of the dough and roll it into a small ball with your hands. Place each ball on the prepared baking sheet.
Create Indents: Use the back of a ΒΌ-teaspoon measuring spoon to press a small indent into the center of each mint ball. If the spoon sticks, you can dust it lightly with powdered sweetener or dip it in a tiny bit of water.
Chill the Mints: Place the baking sheet in the fridge and chill for about 1 hour, or until the mint bases are firm.
Melt the Chocolate: In a small, microwave-safe bowl, combine the heavy whipping cream and chocolate chips. Microwave for 1 to 2 minutes, stirring every 30-45 seconds, until smooth and melted.
Prepare for Piping: Let the melted chocolate sit for a few minutes until it thickens slightly to a yogurt-like consistency. Be careful not to let it sit too long, or it will harden.
Add Chocolate Topping: Transfer the chocolate mix to a disposable decorator's bag with a tip, or use a Ziploc bag with a small corner snipped off. Remove the chilled mint buttons from the fridge.
Finish & Chill: Pipe the chocolate into the indent of each mint button. Return the completed candies to the fridge for another hour, or until the chocolate has fully set.
