Place two pots filled with water on the strove and bring them to a boil. 

Once your water is brought to a boil, add another pot on top and place the milk chocolate in one and the white chocolate in the other. 

Place a lid over the pot and allow it to melt while stirring every few minutes

In the heart shaped molds add one layer of sprinkles

Once the chocolate is finally melted our it into the heart shaped molds

Place the mold into the fridge and let it set for 20 minutes

Once they are complete and hardened you can put them on display or gift them to your loved ones for valentines day
