Add 1 cup of chocolate chips and 2 tbsp of oil to a heat-safe bowl. Microwave for 1 minute and 30 seconds or use the double boiler method to melt the chocolate and oil.
Stir with a forkuntil all the oil and chocolate are mixed and smooth.
Allow to cool for a few minutes until it starts to firm slightly and will stick to the sides of the molds. (This will temper your chocolate).
Fill the chocolate molds
Spoon in about ½ tsp of chocolate mixture into the bottom of each mold. (Enough to cover the colored silicone bottom).
Stir each mold with a butter knife, pulling the chocolate up the edges of the candy mold enough to cover the edges.
Spoon in the filling of choice, like peanut butter, jelly, caramel, or peppermint cream. Use about 1/2 tsp. in the center of each chocolate.
Drop the mold from about an inch above the countertop a few times to flatten the filling so you can add the final layer of chocolate.
Spoon in more melted chocolate, enough to completely fill the molds.
Drop the chocolate mold onto the countertop a few more times from about an inch above the countertop to get out any air bubbles and make the top flat and smooth.
Remove any excess chocolate from the top of the mold.
Decorate and freeze
Add any sprinkles or garnishes you want to the bottom of the chocolates like colored sugar, sprinkles, or Kosher salt.
Freeze your chocolates for ½ hour to make them set.
Pop-out the chocolatesby allowing them to sit out of the freezer for a minute or two, then turning the mold upside down and giving a little push on the silicone part of the mold.
Drizzle additional chocolate or white chocolate over them if you wish.
Fill your boxes with chocolates placed in a paper candy cup.
Store in the freezer.
Notes
Do not overheat your chocolate!
Use a clean dry bowl and molds for your chocolates, even a few drops of water can thicken and ruin your chocolate.
Use oil, not margarine to mix with your chocolates. Margarine has water in it and it will make your chocolate thick.
Your chocolate should be smooth and shiny when melted.
Allow the chocolate to cool back down to a slightly thick and sticky consistency before filling your molds.
Work quickly to put your chocolates into candy boxes. Handling the chocolates too much causes them to start to melt slightly and leave marks on them.
