Preheat oven to 350˚F.
Place 2 tbsp butter and 9 oz chocolate (I recommend 63%) in a microwavable measuring cup or bowl. Melt this in the microwave.
In a mixing bowl, mix together the remaining 7 tbsp softened butter and all the sugar. Then mix in the egg, hot water, and peppermint extract.
Add the chocolate mixture. Mix in almond flour.
Mix in spelt flour, salt, and baking soda.
Finally, mix in any additional chocolate chips (I like white chocolate chips here).
Bake at 350˚F for ~15 min. Remove from the oven even if they look slightly undercooked. Let cool 5 minutes in the pan. Then, remove them from the pan (if removed too soon, they will fall apart).
