Butterbeer

I'm making butterbeer for my sister for Christmas. I'm storing the recipe ideas here so I don't lose them.

RECIPE 1
1 cup (8 oz) club soda or cream soda
½ cup (4 oz) butterscotch syrup (ice cream topping)
½ tablespoon butter

1: Measure butterscotch and butter into a 2 cup (16 oz) glass. Microwave on high for 1 to 1½ minutes, or until syrup is bubbly and butter is completely incorporated.

2: Stir and cool for 30 seconds, then slowly mix in club soda. Mixture will fizz quite a bit.

3: Serve in two coffee mugs or small glasses; a perfectly warm Hogwarts treat for two!

RECIPE 2
1/4 cup sweetened condensed milk
1/4 cup butterscotch topping
2 tablespoons whipped butter, room temperature
1 1/2 cups vanilla cream soda

Combine condensed milk, butterscotch topping, and butter in a glass heatproof measuring cup. Heat in microwave for 1 minute. Remove and stir until butter has melted and incorporated into mixture. Meanwhile heat cream soda in another heatproof measuring cup for 1 minute 30 seconds.

Divide butterscotch mixture between 2 (10 to 12-ounce) mugs. Fill mugs with heated cream soda and stir thoroughly. Serve garnished with an old-fashioned butterscotch candy stick.

RECIPE 3
FOR THE BUTTERBEER
6 12-ounce bottles cream soda [I prefer IBC or Polar Classics Vanilla, but any will work perfectly]
3 teaspoons imitation butter, or clarified butter (instructions linked above)

FOR THE FOAM
2 cups heavy cream
6 tablespoons sugar
2 teaspoons vanilla extract
1 1/2 teaspoons imitation butter

To make the butterbeer: Set out 6 16-ounce glasses. Place 1/2 teaspoon of imitation butter in each glass. Pour 12 ounces of butterbeer into each glass. Lightly stir, if necessary.

To make the foam: In a large bowl, or the bowl of a standing mixer, whip the heavy cream on medium high speed for 3-4 minutes until it starts to thicken. Add the sugar and continue whipping until very soft peaks begin to form, another 3-4 minutes (if you need to whip more or less, then be sure to do so, the times can vary quite a bit based on environment). Stir in the vanilla and imitation butter, then whip for another 30 seconds or so, until soft peaks form.

Spoon a generous portion of foam on top of each glass of butterbeer. Serve immediately.
