Line a cookie sheet with wax or parchment paper or aluminum foil.
Melt the white chocolate in the microwave, stirring every 30-45 seconds, or using a double boiler.
**If you would like to decorate them like a pumpkin, remove ~¼ cup of melted chocolate and place it in a separate bowl. Add orange food coloring to the larger portion of melted chocolate and green food coloring to the reserved portion.
Remove the truffles from the freezer and use a spoon or a candy dipping spoon to fully coat them in (*orange-colored) chocolate.
Place the coated truffles on to the prepared cookie sheet and put them in the fridge to set for a few minutes.
Add the green-colored melted chocolate to a piping or ziploc bag and cut a very small tip.
Remove the truffles from the fridge and add a green tip on top of the truffle to resemble the pumpkin stem, with swirls to resemble vines (if desired).
Place the truffles back in the fridge to fully set, then place them in a sealed container. Store them in the fridge.
