Step 1

Combine the water, granulated sugar, corn syrup, and cocoa powder in a small saucepan. Whisk until smooth. Set over medium heat and bring to a low boil.

Step 2

Remove from the heat and immediately add the peppermint extract and chocolate chips, stirring until all of the chocolate has melted.

Step 3

Set aside to cool. The sauce will appear very thin, but will thicken as it cools. Serve warm (or chilled from fridge) over ice cream or incorporate into your favorite milkshake. Store in a jar in the refrigerator for up to 10 days.
