Swap the espresso martini for this decadent (but not-too-sweet) coffee cocktail. At first glance, this chocolate-infused medley may look like a dessert cocktail, but the addition of bitter elements like stout and coffee liqueur help balance out the condensed milk for a not-too-sweet bevvy. If you haven’t made a flip before, you might be surprised by the egg, which is used to emulsify the ingredients and create a rich texture.—Christine Sismondo
