Place the chocolate chips in a microwave-safe bowl. Heat in 3-second bursts, stirring well after each, until fully melted and smooth.

Dip one side or edge of each fortune cookie into the melted chocolate, letting any excess drip off.

Arrange the dipped cookies on a parchment-lined baking sheet or tray.

While the chocolate is still warm, sprinkle with rainbow sprinkles.

Let the chocolate set, then serve or store in an airtight container until ready to serve.
