Here you go. It makes a lot but keeps for a year. Or of course the recipe could be halved. For individual servings, it works out to a scant 3T of the mix to 1 cup of milk. I typically use about 3/4 c. 1% milk and the rest whole milk, if I've got it. I made it once with their specified whole milk/half&half, and it was heavenly, but I can't afford that many calories for breakfast (not that this is diet food

) And I omit the cayenne.
Hot Chocolate Mix
The Back in the Day Bakery Cookbook
2 cup dutched cocoa, sifted
8 oz. semi-sweet chocolate, finely chopped
3/4 c. packed brown sugar
1/4 c. granulated sugar
1-1/2 t. espresso powder
1/4 t. freshly grated nutmeg
1/2 t. cinnamon
1/4 t. fine sea salt
1/4 t. cayenne peper
Combine all the ingredients in a medium bowl and mix well. Store in an airtight container for up to 12 months.
Hot Chocolate for four: Heat 2-1/2 c. whole milk and 2 c. half & half until steaming. Turn the heat to low and simmer the milk for 6-7 minutes; do not let it boil. Remove the pan from the heat and whisk in 3/4 cup hot chocolate mix until smooth and creamy.
p.s. As far as the cookbook in general, I've made several things and they were all winners, with one exception. The cinnamon buns were definitely subpar compared to other recipes I've made.
