Line a tray with parchment paper. If you have a wire rack, set it over the tray so drips fall onto the parchment.
Add the chocolate chips and coconut oil to a microwave-safe bowl. Microwave in 20 to 30 second bursts, stirring well each time.
Stop when there are a few small pieces left, then stir until smooth. (Chocolate finishes melting from the heat of the bowl.)
Hold each strawberry by the green stem and dip into the melted chocolate. Rotate to coat evenly and keep the leaves clean.
Let the excess drip for a few seconds, then lightly scrape the bottom against the edge of the bowl.
Place dipped strawberries on the wire rack or parchment-lined tray, leaving space between each one. Add sprinkles right away, before the chocolate sets.
Refrigerate for at least 30 minutes, or until the chocolate is firm. Enjoy right away, or keep chilled.
