Ever since I started reading the Harry Potter series in third grade, I’ve been obsessed with trying to create my own version of an old wizard favorite — Butterbeer. The perfect accompaniment to a handful of chocolate frogs.

Now, I don’t believe there are specific ingredients out there for this magical beverage. While the recipe may be up for interpretation, the book describes butter beer as a “less sickly butterscotch.” It’s also served hot and with a generous serving of whipping cream!

Keto Butterbeer Recipe

At any rate, the recipes that I did find online varied greatly — some with sugar and water, pumpkin juice, and even frozen butterbeer.

Out of desperation, I decided to take matters into my own hands. With a few flicks of my wand I was off to the kitchen with a warm drink in my heart.

  2. Add spoonful of butterbeer mixture
  3. Stir, froth or use an electric mixer to combine

  • ½ cup butter unsalted
  • ½ cup heavy whipping cream
  • ½ cup golden monkfruit sweetener
  • ¼ cup erythritol powdered
  • 1 tsp salt
  • 1 tsp cinnamon
  • ½ tsp vanilla extract
  • ¼ tsp nutmeg
  • ¼ tsp ginger


  • In a sauce pan, melt butter over medium heat. Stir occasionally until a light brown color develops (approximately 8-12 minutes)
  • While butter is browning, combine rest of the ingredients (aside from the vanilla) and stir to combine.
  • When butter is slightly browned, turn heat to medium low and stir in the other ingredients. I find that a whisk works best.
  • Add in heavy whipping cream and whisk to combine. Stir every so often. As soon as you start seeing a few small bubbles, remove from heat.
  • Whisk in vanilla.
  • Cool mixture for at least 20 minutes before pouring into a glass jar. Mixture can be used immediately or cooled in the fridge for up to 5 days.

To Prepare the Butter Beer

  • Add half a cup of boiling water to your favorite mug.
  • Take a heaping spoonful (or 2) of your Butter Beer mixture and melt it in the boiling water. Blending with a milk frother works really well.
  • If you're feeling boozy, add a shot of spiced rum. This recipe is delicious either way!
  • For something extra indulgent, add a spoonful of whipped cream!

The butterbeer mixture will come out sort of like a thick butterscotch topping. The flavor is amazing and deep — it would probably go great in coffee, too.

Tips & Substitutions

  • Make the butterbeer mixture in advance if you’d like to serve this at parties or have it ready to go after a long day at work!
  • This recipe is just as delicious without the rum, but they do go down fairly easy! Be careful.
  • If you’d still like to leave a taste of rum without a shot of alcohol, consider adding rum extract.
  • If you don’t have any of the golden sweeteners (or those meant to be a brown sugar substitute), you can use all regular sweetener.
  • While it’s very unlikely to be Keto friendly, the Wizarding World of Harry Potter at Universal Studios serves their own version of the drink — the recipe is a secret — but it’s on my bucket list in the upcoming years!
  • Yep, this is the Harry Potter Butterbeer you’ve been looking for.
