Combine the chocolate chips and condensed milk in a medium microwave-safe bowl.
Microwave on high for 30 seconds. Stir. Microwave for an additional 30 seconds. Stir. Repeat as needed until the chips are 75% melted. At that point let it sit for a few minutes so the rest melt from the residual heat.
Stir in the extracts.
Stovetop
Add the chocolate chips and condensed milk to a small saucepan. Heat over low, stirring, until the chips melt.
Stir in the extracts.
Assembly
Pour in the prepared container. Sprinkle with the sprinkles.
