Melt white chocolate in a double boiler or in the microwave at 20-30 second intervals, stirring well between each time.
Once the chocolate is melted, stir in 2 drops of green gel food coloring. Stir well and add additional drops as needed until you reach your desired shade of green.
One at a time, add a treat stick to one end of a Rice Krispies Treat, then dip the opposite end of the treat into the chocolate. Immediately place a jumbo heart sprinkle onto the dipped treat and place on the wax-lined baking sheet.
Once all of the treats have been dipped, allow the chocolate to set. Chocolate will set in 1-2 hours at room temperate or 15-20 minutes in the refrigerator.
Notes
Treats can be stored at room temperature in an airtight container for 3-4 days.
