1. Preheat oven to 325 ⁰F.
2. Soften the chocolate bar and coconut oil by heating them in a bowl in the microwave or by using a double boiler. Then mix together.
3. In a separate bowl, mix together all the remaining ingredients.
4. When the chocolate and coconut oil mixture has softened and cooled (so as not to cook the egg whites), combine the two bowls of ingredients and mix until uniform.
5. Pour batter into heart-shaped silicone molds.
6. Bake for 15 minutes.
7. Enjoy your creation!
