3. Flavor the Chocolate and Spoon Into a Candy Mold

(Video below)

Ingredients:

The melted chocolate (from previous step)
The butter/flavor mixture (from first step)

Stir one teaspoon of the butter/flavor mixture into the melted white chocolate. Mix well.

Spoon the mixture into the heart-shaped candy molds.

Now, the chocolate needs to dry until firm — probably a few hours. How long it takes to dry depends on the type of chocolate you used, the ambient humidity, and the room temperature.

(DO NOT REFRIGERATE. Refrigerators have so much humidity that the chocolate would tend to get sticky after being removed from the chill.)

As noted, the chocolate in the candy mold will need to dry before it can be removed.
