Baked Alaska
Baked Alaska is a composed dessert built from a layer of sponge cake, a dome or block of ice cream, and a thick coating of meringue that's browned quickly under a broiler or with a kitchen torch just before serving. The meringue insulates the ice cream from the heat long enough to toast the outside without melting the inside, which is the trick that makes the dessert work at all.
Varieties
Some versions are flambeed with rum or brandy poured over the meringue and lit tableside instead of being browned in the oven or with a torch, giving a caramelized crust and a dramatic presentation rather than a different flavor base.
Buying tips
Use a dense, low-overrun ice cream (the kind that feels heavy for its volume) rather than a soft-serve style, since it holds its shape better while the meringue browns. If buying sponge cake instead of baking one, choose a plain vanilla or genoise-style cake without added frosting, since frosting will melt and separate under the broiler.
Substitutes
Italian meringue (in place of French or Swiss meringue) — 1:1 by volume
Made by beating egg whites while pouring in hot sugar syrup, which cooks the whites in the process. It's more stable under a torch and holds its shape longer before deflating, making it the safer choice for a dessert that has to survive being carried to the table.
Marshmallow fluff — 1:1 by volume
Skips the whipping and browning risk of raw egg whites entirely. It browns less evenly under a torch and tastes more one-note sweet, but it's the fastest fix if meringue isn't holding together.
Fruit sorbet in place of ice cream — 1:1 by volume
Gives a dairy-free, lighter version and pairs especially well with a berry or citrus sorbet under vanilla-scented meringue, though the flavor reads sharper and less rich than with ice cream.
Brownie base in place of sponge cake — same thickness, about 1/2 inch
A denser, fudgier base that holds its structure well after freezing and stands up better to slicing than a delicate genoise.
Store-bought pound cake in place of homemade genoise — same thickness slice
Cuts significant prep time and gives a sturdier crumb, though the flavor is heavier and less airy than a classic sponge base.
Storage
Assemble the cake and ice cream layers, wrap tightly, and freeze solid (at least 4-6 hours, ideally overnight) before adding meringue. The meringue should go on and get browned right before serving; once torched or broiled, it doesn't hold well and should be eaten within about 15-20 minutes before the ice cream starts to soften.
How to use
Serve baked Alaska sliced immediately after browning the meringue, while the outside is still warm and the inside is still frozen. It's typically made as one large dessert for a table rather than individual portions, though mini versions built in ramekins or on cupcake-sized cake rounds work the same way and torch faster.
What it pairs with
A thin raspberry or passionfruit coulis spooned around the plate cuts the sweetness of the meringue. Fresh berries or a dusting of espresso powder also work well against the very sweet, very rich combination.
Nutrition
Baked Alaska is calorie-dense by design, combining sugar-heavy meringue, sweetened ice cream, and cake in one slice. A typical wedge runs several hundred calories, most of it from sugar and the fat in the ice cream rather than the meringue itself.
FAQ
Why doesn't the ice cream melt when baked Alaska goes under the broiler?
The meringue is a poor conductor of heat and traps air, so it insulates the frozen ice cream long enough (usually under 2-3 minutes at high heat) for only the meringue's surface to brown before heat reaches the ice cream underneath.
Can baked Alaska be made ahead of time?
The cake and ice cream layers can be fully assembled and frozen up to a few days ahead, wrapped airtight. The meringue should be made and browned no more than about 30 minutes before serving.
Is a kitchen torch necessary, or can it go under the broiler?
A broiler works fine and is the traditional method, but it heats the whole dessert at once, so the ice cream has less buffer time. A torch lets you brown just the meringue's surface in a few seconds with the rest of the dessert staying frozen longer.
Why does the meringue sometimes weep or turn watery?
Underbeaten egg whites or undissolved sugar cause weeping. Beat whites to stiff, glossy peaks and make sure sugar is fully incorporated before piping or spreading the meringue.
