Gently combine the heavy cream, milk, white chocolate chips, sweetened condensed milk, and vanilla extract in your slow cooker. Stir until everything is nicely mixed.
Set your slow cooker to low heat for 2 to 3 hours. Make sure to stir the mixture every 20-30 minutes until the chocolate is fully melted and smooth.
Once melted, add a few drops of green food coloring, then adjust with yellow and more green until you achieve that vibrant Grinch green color you love.
Keep the hot chocolate on the warm setting for up to 3 hours for serving. Feel free to top with a sprinkle of mini marshmallows or a swirl of whipped cream for extra fun!
