Ingredients
- Butterscotch beer or cream soda: gives the authentic butterbeer taste Choose a quality soda that smells rich when you open it
- All purpose flour: ensures the cake has structure Spoon and level for best texture
- Baking powder and baking soda: help the cake rise for a fluffy crumb Check if your baking powder is fresh by seeing if it bubbles in water
- Salt: balances the sweetness and enhances every flavor Use a fine sea salt for a cleaner taste
- Unsalted butter: adds richness Use real butter for full flavor and let it soften at room temperature before mixing
- Light brown and granulated sugar: add depth and sweetness The brown sugar’s molasses gives that butterscotch warmth
- Eggs at room temperature: bind and give structure Let them sit out ahead so your batter is smooth
- Vanilla bean paste or extract: builds aromatic magic Vanilla paste gives those lovely specks in the crumb
- Butter extract: deepens the classic butterbeer hint Avoid imitation extracts if possible
- Butterscotch chips: melt into the cake for concentrated flavor Choose a smooth brand and let it cool before adding
- Buttermilk: ensures softness and moisture Only use fresh or homemade buttermilk never sour milk
- For the frosting more unsalted butter: makes a smooth base and melted butterscotch chips bring richness
- Powdered sugar: adds sweetness and structure Sift for lump free frosting
- Heavy cream in the sauce: gets the perfect pourable consistency Choose fresh cream with good fat content
- Honey: brings a silky finish and gloss to the homemade sauce Pure honey works best
Step-by-Step Instructions
- Prepare the Butterbeer Reduction:
- Pour the butterscotch beer or cream soda into a large pot and simmer over medium heat until it reduces to half a cup. Stir occasionally. This intensifies the flavor and takes about thirty minutes. Cool it until it feels just barely warm on your finger
- Mix the Dry Ingredients:
- In a medium bowl whisk together the flour baking powder baking soda and salt until completely combined. This helps ensure your leaveners are evenly dispersed
- Cream the Butter and Sugars:
- In a large bowl use an electric mixer to beat the softened butter light brown sugar and granulated sugar on high speed until fluffy and pale in color. This usually takes one to two minutes and creates an airy structure for the cake
- Add Eggs and Extracts:
- Add the eggs vanilla bean paste and butter extract to the creamed butter mixture. Continue mixing on medium speed until the batter looks thicker and lighter. About one to two minutes is perfect
- Blend in the Reduced Soda and Melted Butterscotch:
- Add in your cooled butterscotch beer reduction and melted butterscotch chips. Beat together on medium speed until the mix looks uniform and golden
- Combine Wet and Dry Ingredients:
- Alternate adding buttermilk and the dry flour mixture to your bowl in batches mixing on low speed until fully smooth. Scrape down the sides with a spatula so nothing is missed
- Bake the Cake:
- Pour the batter into a parchment lined nine inch square pan. Bake at three hundred fifty degrees Fahrenheit for twenty seven to thirty one minutes. Test with a toothpick and let the cake cool in the pan on a wire rack
- Make the Butterbeer Buttercream:
- Whip softened unsalted butter with a pinch of salt on high until extra pale and fluffy which takes five to ten minutes. Add melted butterscotch chips and blend in. Sift in powdered sugar and mix on low until smooth then finish on high. Add vanilla and butter extract for a final beat to maximum fluffiness
- Create the Butterscotch Sauce:
- Combine butterscotch chips and heavy cream in a microwaveable bowl. Heat in thirty second bursts and stir until melted. Once smooth stir in the honey and cool slightly
- Assemble and Decorate:
- Remove the cooled cake from the pan by lifting the parchment. Spread a generous layer of buttercream over the top. Drizzle the butterscotch sauce and swirl gently using the back of a spoon. Finish with gold or white sprinkles for a festive touch
