1 // Line a baking tray with parchment paper and pour your sprinkles into a shallow dish or two. Set aside.
2 // Add about 1-inch of water to a double boiler (or a saucepan with a metal bowl nestled atop). Heat over medium-low heat, slowly stirring the chocolate so it melts into a smooth consistency. White chocolate has a lower melting point, so it can seize easily.
3 // Dip the edge of the cones in the melted white chocolate, then lightly dust with sprinkles while the chocolate is still melted.
4 // Place the cones upside down on the paper-lined tray, and place them in the fridge, allowing the chocolate to set for at least 15-20 minutes.
