It will take about 3 hours.Chocolate coating:Using a small saucepan in a hot water bath inside a larger sauce pan on the stove, melt the baking chocolate.As the chocolate melts, add the vanilla extract and the Confectioner's Swerve and stir well until completely dissolved.Prepare an ice bath that can fit the small saucepan on the side of the stove.Once all your mousse cubes are ready to be dipped and handy nearby, get the chocolate to the right consistency: not too runny and not too dense, by bringing it to the ice water bath.One at a time dip and coat the peanut mousse cubes, until completely coated, helping yourself with a spoon.Once coated place them on to a cookie sheet lined with parchment paper to cool.Once all coated I would refrigerate them for 10 minutes to set the coating.Store the resulting Chocolate Coated "Bullwinkles" in the refrigerator until ready to eat.They will not melt at room temperature so they can be also kept outside the refrigerator for transport.
