Ingredients

Why this recipe works

The combination of warm butterscotch sauce and cold frosting creates a delightful temperature contrast.

The sauce seeps slightly into the sponge layers, adding moisture and flavor, while the mascarpone frosting stays light and airy. The candied pecan praline provides a crunchy texture that balances the soft cake and creamy frosting.

Using store-bought or made-ahead sponge layers simplifies the process without sacrificing quality. The whipped mascarpone butterscotch frosting is easy to spread and holds its shape, making assembly straightforward.

The finishing touches—chocolate curls, praline, and sea salt—add visual appeal and layers of flavor that make this cake feel special.

Notes and substitutions

For the cake layers, use a light and fluffy sponge—either from a bakery or a homemade recipe. If making ahead, wrap the layers tightly in plastic wrap and store at room temperature for up to a day. The frosting can be prepared a day in advance and kept chilled; bring it to room temperature and whisk briefly before using.

Caramelized blonde coverture chocolate is a type of chocolate with a caramelized flavor; if unavailable, use high-quality white chocolate and add a pinch of caramel extract. The butterscotch sauce should be warm but not hot when poured, so it flows smoothly. Flaky sea salt, such as Maldon, is ideal for the finishing touch.

• caramelized blonde coverture chocolate: white chocolate with a touch of caramel extract, or use a high-quality white chocolate bar.
• whipped mascarpone butterscotch frosting: Use a stabilized whipped cream with butterscotch pudding mix, or a cream cheese frosting with butterscotch syrup.
• candied pecan praline: Use store-bought praline pecans or caramelized pecans, or make your own by tossing pecans with sugar and baking.
