Recreating the infamous Butterbeer

I have tried many different recipes for butterbeer but I have not been completely satisfied so I combined a couple of the recipies and altered them until I came up with something I liked.

FOR THE BUTTERBEER
1 liter of cream soda
1 tsp of butter flavoring

FOR THE FOAM
2 cups heavy cream
3 tablespoons sugar (most recipes called for more but I didn't want all that extra sugar)
2 teaspoons vanilla extract
1 tsp of butter flavoring

**If you have some glass mugs, I recommend you put them in the freezer before making the drink so you can have a nice frosted mug to put your delicious butterbeer in.

For the foam, whip the heavy cream, sugar, vanilla, and butter flavoring together. Beat it until you get the consistancy you want. 

Next, put a tsp. of butter flavoring in the bottom of your mug then pour the cream soda in and mix. Put as much foam as you want on top of the drink and enjoy!
