I highly recommend the use of a silicone mold for these chocolate cups. See notes below for a link to the one I used. Wash and dry your mold and set aside.

Place chocolate disks in a medium microwave safe bowl. Microwave for 30 seconds. Stir and then microwave again for 30 seconds. Repeat until all chocolate is melted. Place about 2 ounces (4 tablespoons) of melted chocolate into plastic sandwich bag and seal. Set aside.

Spoon about 2 teaspoons of melted chocolate into one mold. Brush chocolate to the edges using a pastry brush until the whole mold is covered in chocolate. Make sure the edges are loaded with as much chocolate that will stick in place. The edges are delicate so we don't want the chocolate layer to be too thin. Repeat with other 11 molds. You may need to reheat chocolate to melt it again. Reheat in 15 second intervals.

Once all molds are filled, place in freezer to chill the molds for 10 minutes. This will solidify the chocolate. Remove solid molds from the freezer. Push the chocolate cups out of the mold from the bottom, being very very gentle, to release the cup. It's okay if the edges aren't perfect but you don't want the whole thing to crack.

Fill each mold with an assortment of berries. Grab the sandwich bag filled with chocolate. Snip a corner off the bag and then drizzle chocolate over each cup. Refrigerate until chocolate has hardened again. Serve within the next couple of days, or before fruit goes bad. Refrigerate leftovers.
