This is an amazing dessert beverage. I wish I could take credit for the idea, but yet again it was a bon appetit idea. When I saw this in the February 2011 issue, I knew I had to try it. I was pregnant at the time, but I finally tried making these about a month ago. I'm not much of a beer drinker, but if I drink beer, I tend to prefer darker, smoother beers and I've liked the beers with chocolate in them. However, my mother doesn't like Guinness at all and she really liked these, so if you're at all intrigued, just try making them!
Since the recipe is available online, I'm sharing it here.
Float
1 cup heavy cream
1 teaspoon vanilla extract
Kahlua
cocoa syrup
chocolate ice cream
3 bottles Guinness or other stout
Whip the cream and vanilla extract using an electric mixer. For each float, place one scoop of chocolate ice cream in a glass. Pour 1 tablespoon cocoa syrup and 1 tablespoon Kahlua over the ice cream. (Alternative: I prefer 2 tablespoons cocoa syrup and 2 tablespoons Kahlua per float.) Add half a bottle of stout to the glass, pouring gently down the side of the tilted glass to prevent too much head from forming. Spoon a dollop of whipped cream on top and drizzle cocoa syrup over the whipped cream. Serve with a straw. Makes 6 floats.
Cocoa Syrup
2/3 cup sugar
1/2 cup unsweetened cocoa powder
2/3 cup boiling water
1 teaspoon vanilla extract
Whisk the sugar, cocoa powder, and a pinch of salt together in a small saucepan. Pour 2/3 cup boiling water into a heat-resistant measuring cup. Whisk just enough boiling water from the cup into the cocoa mixture in saucepan to form a smooth paste, then whisk in the remaining water. Bring to a simmer over low heat, stirring constantly. (I get impatient and use medium heat and it has come out fine.) Simmer syrup 1 1/2 minutes, stirring often. Remove from heat. Stir in vanilla extract. Cool to room temperature. Can be made 3 weeks ahead. Cover and chill.
