Dec 08, 2016 Baby, It's Cold Outside Brrr, it's chilly outside! Warm yourself up with our vintage hot chocolate (the recipe was published in the Kansas City Star in December of 1911). We use Hartzler's whole milk, melted chocolate and a little coconut milk and eggs (pasteurized) to give it extra richness. Served with your choice of a large homemade marshmallow or whipped cream. Have a cup with a made-from-scratch Snowflake Sugar Cookie.
