The next day, take the chocolate chips and oil in a small bowl.
Heat in microwave for 30 seconds and then mix.
Heat another 10 seconds and mix again
Repeat this till all the chocolate is mixed in and you see no lumps. Alternatively, you can melt the chocolate over a water bath as well
Let the chocolate cool to room temperature
While the chocolate is cooling, lets take the ice cream bars out of the mold.
To make it easier, run the mold under warm water and then carefully remove the ice cream bars
Place them on a tray lined with parchment paper and pop it in the freezer to let the ice cream bar firm up
Move the cooled chocolate to a tall glass or container. The container needs to be deep enough to immerse the ice cream bars.
Dip the ice cream bars in the chocolate and shake it off a bit to let the extra chocolate drain off to leave behind a thin coat/shell of chocolate.
Just before the chocolate hardens around the ice cream bars, you can add any decors like sticking the pretzel, candy eyes and red M&M's to make Rudolf the Red-Nose-Reindeer
The chocolate should harden within 15 to 20 seconds.
Pop it back in the freezer or you can enjoy these right away.
