As soon as it's Harry Potter movie night at my place, this fudge with that butterbeer flair makes an appearance. Imagine big butterscotch, creamy white chocolate, and sweet caramel all swirling together in every bite. It's like a bit of Hogwarts right on the table.

This treat totally took off at our place after my kids asked for a big Harry Potter birthday bash. I whipped up three batches one week. Now anytime we want something magical but easy, this fudge is a must.

Delicious Ingredients

  • Sweetened condensed milk: It keeps everything sweet and thick—the regular stuff (not low-fat) is where it's at if you want that dense texture
  • Marshmallow crème: Brings a super soft, creamy texture—make sure it's nice and fresh so it melts fast
  • Salted butter: This is what gives you that rich butterscotch kick and helps everything set up—spring for a decent brand for best results
  • Caramel ice cream syrup: Extra caramel flavor that makes it taste just like real butterbeer—real caramel is better than butterscotch syrup here
  • White chocolate chips: This is your smooth top layer—check that cocoa butter’s listed for good melting
  • Granulated white sugar: Evens out the sweetness and helps the fudge firm up—just use the regular fine stuff
  • Butterscotch chips: The real heart of that butterbeer flavor—go for a brand that isn’t waxy and has bold taste

Tasty Step-by-Step Directions

Slice and Serve:
Once everything’s chilled through, grab the edges of the parchment and pull it all out. To cut clean squares, dip a sharp knife in hot water and wipe between cuts. Serve these bites cold from the fridge or let them warm up to room temp if you want extra creamy layers.
Chill Until Firm:
Pop the whole pan in your fridge for a couple hours, or the freezer for close to an hour, until it's nice and set. The fudge should come away from the paper without any sticking.
Melt in White Chocolate:
Take the pan off the heat and stir in the white chocolate chips until they just melt—don’t keep going too long or it’ll get grainy. Spread this white chocolate layer gently over the semi-chilled base and smooth out to the edges.
Make the White Chocolate Mix:
With a clean pot, stir together the last of the marshmallow crème, butter, sweetened condensed milk, and sugar. Stir non-stop as it heats up. When it bubbles, drop the heat a bit and let it go two minutes, still stirring the whole time.
Set the Bottom Layer:
After mixing, pour the butterscotch layer into your lined pan. Tap the pan to flatten it out, then slide it in the freezer so it firms up while you do the next step.
Blend in Butterscotch:
Once you’ve bubbled the mix for four minutes, dump in the butterscotch chips. Take it off the burner and stir until melted and smooth—keep whisking a minute so the fudge thickens but still pours easily.
Boil the Base:
After you start seeing bubbles, set your timer for four minutes. Don’t walk away—keep stirring as it goes gold and thick. This way, you'll get fudge that’s easy to pour but holds its shape.
Butterbeer Magic Start:
Melt butter, marshmallow crème, sweetened condensed milk, sugar, and caramel syrup in a pot over medium-high heat. Stir non-stop as things start melting so nothing sticks or burns at the bottom.
Get Your Pan Ready:
Line an eight-inch baking pan with parchment paper and give it a quick shot of cooking spray. This keeps the fudge from sticking and makes it super simple to lift out later.

I always go back for that thick butterscotch middle. I remember making this for my niece’s first Harry Potter celebration—she wore her cape (homemade, of course) and said everyone had to grab a piece before we even started the games.

Storing Butterbeer Fudge

Stick any extras in a container with parchment or wax paper between stacked layers. It lasts about a week in the fridge, or up to two months in the freezer. If you freeze, let it sit out ten minutes so it’s soft and tasty again.

Simple Swaps

No salted butter? Just mix in a tiny pinch of salt in every layer if you’re using unsalted. Need it nut free? Double check those chips, just to be sure. Want more caramel taste? Swap caramel syrup for some dulce de leche.

Fun Ways to Serve It

Perfect for birthdays, any fantasy or wizard themed party, or in your holiday treat box. Goes super well with mugs of warm milk, spiced cider, or even a simple butterbeer knockoff drink. For a party tray, toss in some chocolate frogs or gummies for the best kind of magical spread.

A Touch of Magic

You might know butterbeer from Harry Potter—students sipped it all through Rowling's books. This fudge takes all those sweet, creamy flavors and brings them together with regular stuff you’ll find at the grocery store—no Hogwarts train ticket needed.

What You'll Need

→ Butterbeer Fudge Layer

01 1 bag (312 grams) butterscotch chips
02 1/4 cup (60 milliliters) caramel syrup for ice cream
03 1/2 cup (100 grams) white sugar
04 3/4 cup (180 milliliters) sweetened condensed milk
05 about 3/4 cup (120 grams) marshmallow fluff — just over half a 7-ounce jar
06 10 tablespoons salted butter

→ White Chocolate Layer

07 the rest of your 7-ounce jar marshmallow crème (about 1/2 cup, 85 grams)
08 1/4 cup (60 milliliters) sweetened condensed milk
09 170 grams (1 cup) white chocolate chips
10 1/2 cup (100 grams) white sugar
11 1/2 cup (115 grams; 1 stick) salted butter

Step-by-Step Directions

Step 01

Get an 8-inch square pan (20x20 cm). Lay parchment paper inside and spritz a little nonstick spray on top. Move it aside for now.

Step 02

Put salted butter, marshmallow crème, sweetened condensed milk, sugar, and caramel syrup in a medium pot. Set the heat to medium-high. Keep stirring, don’t walk away, until you see bubbles.

Step 03

As soon as it boils, stir on a steady pace for 4 minutes. The mix will get thicker and turn a warm golden color. Toss in those butterscotch chips and keep stirring until everything’s melty and blended. Take off the heat, whisk for another minute or two so it cools a bit but still pours easily.

Step 04

Pour the butterscotch fudge into your pan, smoothing it right to the corners. Let it hang out in the freezer while you get the next layer started.

Step 05

For the top layer, grab a clean saucepan and add sugar, butter, marshmallow crème, and sweetened condensed milk. Turn the heat to medium and don’t stop stirring until the mix bubbles up.

Step 06

Once you see it boiling, dial down the heat a bit and keep mixing for 2 minutes. Take off the heat. Quickly dump in white chocolate chips and gently stir till you’ve got a smooth blend. No need to keep stirring so much—it can mess up the texture.

Step 07

Right away, pour the white chocolate mix onto the cold butterscotch layer. Use a spatula to spread it out even, edge to edge.

Step 08

Stick it in your fridge for a few hours (2 to 3) or speed things up in the freezer for an hour until totally set and hard.

Step 09

Once it’s chilled, pop it out of the pan and slice into 49 chunks (about one inch each). Dig in right away.
