Simple Step-by-Step
- Finish and Decorate:
- Take the cake out of the pan using the parchment. Slather buttercream all over the top. Swirl some butterscotch sauce on using the back of a spoon. Toss some white or gold sprinkles for extra sparkle
- Whip Up the Sauce:
- Add the butterscotch chips and cream to a microwaveable bowl. Heat in half-minute bursts then stir until melted and glossy. Mix in honey and set aside to cool off a bit
- Make the Butterbeer Frosting:
- Beat softened butter with a pinch of salt until super light and fluffy—give it five to 10 minutes on high. Add melted butterscotch chips and blend them in. Mix in sifted powdered sugar on low, then crank it up. Finish with vanilla and butter extract to take it over the top
- Bake Your Cake:
- Spoon your batter into a parchment-lined 9-inch square pan. Slide it into a 350-degree oven for roughly 27 to 31 minutes. Toothpick-test for doneness, then cool in the pan on a rack
- Mix Dry With Wet:
- Go back and forth adding your buttermilk and flour mix in batches. Keep things moving slow and low until your batter’s totally smooth. Scrape the bowl’s sides along the way
- Pour in Reduced Soda and Butterscotch:
- Now add your cooled soda reduction and melted chips right into the batter. Blend it all together until everything looks golden and blended
- Drop in Eggs and Extracts:
- Crack in the eggs, then add the vanilla and butter extract. Keep mixing on medium—you’ll see it thicken and lighten up fast
- Cream Sugars and Butter:
- With an electric mixer, beat softened butter and both sugars on high until pale and full of air—only a couple minutes. This step keeps things light
- Mash Up the Dry Ingredients:
- In another bowl, whisk together your flour, baking powder, baking soda, and salt so the baking powders are really even
- Make That Butterscotch Reduction:
- Tip the butterscotch beer or cream soda into a pot and simmer until you’re left with a half cup. Stir off and on, letting those flavors get strong—takes about 30 minutes. Let it cool just to lukewarm

The butterscotch beer reduction in the batter? That’s the real game changer. It’s like capturing every magical moment from the movies and baking it up at home. Everyone in my house fights for the corner slices with the most frosting and sprinkles.
Keeping It Fresh
Once it’s frosted, this cake stays yummy for four days in the fridge. Wrap it tightly with plastic or stash it in a sealed container. Want to freeze? Go for it—just wrap an unfrosted cake in two layers of cling film and then foil. Frost fresh after thawing for the best bite.
Switch It Up
If you can’t find butterscotch beer, grab cream soda with a buttery caramel smell instead. For buttermilk, regular milk with a teaspoon of lemon juice works just fine—let it sit five minutes. No vanilla paste? Vanilla extract swaps in, but the flavor won’t be quite as bold.

Behind the Magic
Butterbeer is probably the best-known treat in the Harry Potter universe. Rowling wrote that it tastes like mellow butterscotch. Making this cake always brings fans together—birthday bashes, movie marathons, you name it. It’s a cute throwback to the book series that sparked a generation’s love for fantasy. Butterscotch comes from Victorian England, which makes it right at home in a cake like this.
