Found this recipe in my new favorite book: The One-Bottle Cocktail
1oz Reiger’s Kansas City Whiskey (2020 Holiday Edition)
1/2oz maple syrup, diluted 1:1
1/2oz Cold-brew coffee (Streetlight blend from Craft Coffee)
1/2oz buttermilk
Garnish with dark chocolate shavings (recipe calls for hazelnut, but I didn’t have any)
Put it all in a shaker without ice, shake for 20 seconds. Fill with ice and shake for 30 seconds. Double-strain.
Tastes like a mocha milkshake.
Came here to recommend this. Great choice.
