Every time a Harry Potter movie marathon starts at my house this butterbeer fudge appears on our table It captures all the magic of butterscotch white chocolate and caramel in two swirled layers and brings a bit of Hogwarts right to your kitchen
This recipe became a favorite after my kids requested a Harry Potter themed birthday I made three batches in a week and now it is a staple whenever we want a treat that feels special but not too complicated
Ingredients
- Salted butter: Adds rich butterscotch flavor and helps layers set choose a good quality brand for best texture
- Marshmallow crème: Gives the fudge a creamy smooth finish use fresh marshmallow crème for easy melting
- Sweetened condensed milk: Brings sweetness and stability the full fat version works best for thick fudge
- Granulated white sugar: Balances the flavors and aids in thickening stick with regular fine sugar
- Caramel ice cream syrup: Infuses caramel notes which mimic the taste of butterbeer use a real caramel not butterscotch
- Butterscotch chips: Create the signature butterbeer flavor look for chips that are rich and not too waxy
- White chocolate chips: Form a creamy topping that melts easily opt for real cocoa butter in the ingredients list
Step-by-Step Instructions
- Line the Pan:
- Line an eight inch square baking dish with parchment paper then lightly coat it with cooking spray This prevents sticking and will make removing and slicing the fudge much easier
- Butterbeer Fudge Layer:
- In a medium saucepan combine the salted butter marshmallow crème sweetened condensed milk granulated sugar and caramel syrup Place over medium high heat Stir this constantly as it begins to melt and combine so nothing scorches on the bottom
- Boil the Mixture:
- When bubbles appear set a timer for four minutes Keep stirring eagerly The concoction will slowly deepen to a golden brown shade This stage ensures a thick but easy to pour result
- Melt in the Butterscotch:
- After four minutes stir in the butterscotch chips until the chips melt fully and the mixture turns silky Keep whisking off the heat for one to two extra minutes so it thickens but still flows smoothly
- Set the Butterbeer Base:
- Pour the fudge mixture into the lined pan Gently tap the pan on your countertop to level it Slide the pan into your freezer to quick chill while you work on the next layer
- Create the White Chocolate Layer:
- Using a clean saucepan heat together the white sugar salted butter remaining marshmallow crème and sweetened condensed milk Stir without walking away When you see it boil adjust the temperature to medium and continue cooking for two minutes never stop stirring
- Add White Chocolate:
- Remove from heat and smoothly mix in white chocolate chips Watch closely and do not overstir because white chocolate can seize Pour this layer right over the slightly chilled butterbeer base and gently smooth to the edges with a spoon or spatula
- Chill Completely:
- Place the assembled fudge in your refrigerator for two to three hours or in the freezer for about an hour until set The fudge should be very firm and peels easily from the parchment
- Cut and Serve:
- When fully chilled lift the fudge out and cut it into one inch squares Use a sharp knife dipped in hot water for the cleanest cuts Serve chilled or at room temperature to showcase the creamy layers

My favorite part is the bold butterscotch layer It takes me back to the first Harry Potter party I threw for my niece She wore a homemade cape and insisted every guest must have a square of fudge to start the festivities
