Please let me know if you have any questions about this recipe. I read all the comments myself and I try to help as soon as I can. I have readers from all levels of comfort and experience in the kitchen on my site, and I’ve tried to answer some of your questions already in the post.

How to make
The complete recipe‘s below with full ingredient amounts and instructions. I have tips and tricks in the post for you.

It’s a fairly sweet treat. Start with 1 teaspoon lemon juice and add another teaspoon if you prefer a less-sweet Butterbeer. The additional lemon juice balances the sweetness of the cream soda and butterscotch. The lemon juice may seem like an unusual addition to a sweet drink, but a small amount helps balance the sweetness of the cream soda and butterscotch topping.

For the best cold foam, use cold heavy whipping cream. The cold foam should be thick and foamy but still easy to spoon or pour over the soda. Be careful not to over-whip it into stiff whipped cream. If it thickens too much, simply stir in a little milk (even oatmilk) to thin it.
For the best texture and fizz, assemble the Butterbeer just before serving. And serve the Butterbeer immediately.
You could also garnish each glass with a small drizzle of butterscotch topping or a light sprinkle of cinnamon or pumpkin pie spice.
Storage and make ahead
Cold foam: Store tightly covered like in a mason jar with a tight-fitting lid in the refrigerator for up to 1 week. For the best texture, use it within a few days. Give it a quick whisk or froth before using if it has separated.
Assembled Butterbeer: This is best served immediately. Once the soda and foam are combined, the drink will gradually lose carbonation and the foam will soften.
Cream soda: Keep unopened cans or bottles refrigerated until you’re ready to assemble the drinks.
Serving Suggestions
This Butterbeer would be especially good for:
- Halloween parties
- Harry Potter movie nights
- Harry Potter-themed birthday parties
- Fall gatherings
- Kids’ parties
- Halloween sleepovers
- Book club or reading-night gatherings
- Family movie nights
For a party, make the cold foam ahead of time and keep it refrigerated. Pour the cream soda just before serving so it stays fizzy.

Variations
For an adult version, replace the butterscotch topping with 1 ounce butterscotch schnapps and add 1½ ounces gold or spiced rum to each glass along with the cream soda. Note: The boozy version is for adults only.
For a different flavor, you can also try ginger beer instead of cream soda. Ginger beer will give the drink more ginger spice and a sharper, less-sweet flavor. Note that ginger beer can vary considerably in sweetness and intensity, so it will produce a noticeably different drink.
