Tim and I make this every Christmas. We quite enjoy it. We always do a double batch. This will last a couple months stored in the fridge. 1CUP half and half or heavy cream 1 can of sweetened condensed milk 3TBSP chocolate syrup 1TSP instant coffee 1TSP vanilla extract, pure is best though Add all the above to a bowl, mix very well can use hand mixer as well. Then add in 1 2/3CUPS Whiskey stir til combined.I store in a quart size mason jar, any air tight container will work. Store in fridge and shake well before every use. We cant wait to hear what you think.
