If you love sweets or anything from the wizard world, this homemade Harry Potter Butterbeer Fudge will blow your mind. It’s packed with layers of dreamy white chocolate and rich butterscotch, all soft and creamy just like a treat from Honeydukes. As soon as we whip up a batch for a family movie night, it disappears super fast—no magic needed.
I first made this fudge for my kid’s magical birthday bash, and both the grown-ups and little ones kept sneaking back for more. Now we whip it up every single time we do a Harry Potter movie marathon.
Ingredients
- White chocolate chips: melts down for a creamy finish that takes away some of the butterscotch’s boldness. Real white chocolate (with cocoa butter) works best
- Butterscotch chips: brings that classic, sweet butterbeer taste. Get the best ones you can for smooth melting
- Caramel ice cream syrup: adds that caramel vibe so you get the full butterbeer feel
- Granulated white sugar: makes the fudge sweet and helps it keep its shape. Go for super fine sugar if you can
- Sweetened condensed milk: makes every piece super creamy. Use your favorite brand for best flavor
- Marshmallow crème: makes everything stretchy and smooth. Grab a fresh jar—it’ll mix in easiest
- Salted butter: gives that rich, balanced taste. Quality matters, so pick one with just a couple ingredients
Easy Instructions
- Cut and Enjoy:
- Once everything’s cold and set, lift by the parchment and slice into little squares
- Pour and Chill Again:
- Dump the white chocolate mix on top of the cooled butterscotch layer, even it out, then chill in the fridge for a few hours or pop in the freezer for about an hour
- Short Boil and Add White Chips:
- Once you see bubbles, turn the heat lower, stir for two minutes, then pull off the heat and gently stir in the white chocolate chips until just melted. Don’t overdo it—white chocolate seizes up quick
- Make the White Chocolate Top Layer:
- Put marshmallow crème, sugar, salted butter, and condensed milk into a new pot over medium and stir ’til it mixes and boils
- Chill Your First Batch:
- Pour the cooked fudge into your lined pan, smooth it out, then toss in the freezer to set up while you handle the next layer
- Beat Off the Heat:
- Take the pan off the burner and whisk for another minute or two. It should thicken up but stay easy to pour
- Add Butterscotch Chips:
- When your four minutes are up, quickly dump in the butterscotch chips and mix until every bit melts and it’s silky
- Let the Mix Boil:
- Stir constantly as the mix comes to a bubble. Hit the timer for four minutes, keep stirring, and watch until it thickens with a nice golden hue
- Make the Butterbeer Layer:
- Toss salted butter, marshmallow crème, condensed milk, sugar, and caramel syrup in a pan. Use medium-high heat and stir until all melted smooth
- Get the Pan Ready:
- Line an 8 x 8 baking dish with parchment sprayed lightly with oil—it’ll make life much easier when you take the fudge out

The best part for me is when the butterscotch and white chocolate swirl together. The creamy bite and that throwback butterbeer taste always remind us of those lazy, rainy Harry Potter days when the only thing better than the movies is sharing this fudge together on the couch
How to Store
Pop the fudge in something airtight and stash it in the fridge for up to ten days. Want it to last longer? Slip extra pieces in a zipped bag and freeze for three months tops. Let them warm up on the counter so both layers get soft and chewy again before digging in
Swaps That Work
If you’re out of butterscotch chips, toffee chips work too! For dairy-free, try plant-based butter or white chocolate and just melt them a little more gently. If you’re missing caramel syrup, light corn syrup can stand in—just know it won’t taste quite as caramelly
Fun Ways to Serve
This fudge pairs perfectly with a hot mug of cocoa—or go all out and serve with homemade butterbeer. If you’re feeding a crew, cut the pieces smaller so everyone gets a taste. Add whipped cream and a few extra butterscotch chips on top for a magical look

Story Behind It
Fudge started as an old-school American favorite from the late 1800s. The butterbeer flavor is a modern, whimsical twist straight from the Harry Potter stories—meant to be cozy and comforting, just like the made-up drink from the books. Eating this dessert ties back to those warm, festive scenes at the Three Broomsticks
