Baked Alaska is three components — sponge cake, frozen vanilla ice cream, and meringue — baked together for just a few minutes so the outside browns while the inside stays frozen. It takes planning and a couple of hours of freezer time, but none of the individual steps are difficult. Make it when you want something genuinely impressive without buying anything expensive.
Before you start
The two things that actually determine success here are freezer time and meringue coverage. The ice cream needs to be completely solid — not just cold, but hard — before it goes into the oven. If it’s soft at all, three to five minutes at 220°C will melt it through. Give the assembled cake at least two hours in the freezer after you add the sponge base, and longer is better. The second thing: meringue is your insulation. It has to cover every single bit of the ice cream and meet the sponge with no gaps. Any exposed spot is a weak point where heat gets in. Take an extra minute to check the edges and patch any thin areas before it goes in the oven.
Smart swaps
- Caster sugar for meringue: If you only have regular granulated sugar, blitz it in a blender or food processor for 30 seconds. It won’t be as fine as true caster sugar, but it dissolves well enough for a stable meringue.
- Ice cream flavor: Any flavor works — chocolate, strawberry, coffee, or even a store-brand vanilla. Skip the garnish of toasted coconut or chocolate shavings on top; it’s not worth the extra dish.
- Cream of tartar: A small squeeze of lemon juice (about half a teaspoon) does the same stabilizing job if you don’t have cream of tartar on hand.
- Sponge cake: A thin layer of store-bought pound cake or plain sponge cake, cut to fit, works fine as the base. It just needs to be sturdy enough to hold the ice cream mold.
Troubleshooting
- Meringue weeps or goes watery: This usually means the sugar wasn’t fully dissolved. After adding the sugar, rub a little meringue between your fingers — if it feels gritty, keep whisking. The finished meringue should feel completely smooth.
- Ice cream melts before the meringue browns: Your oven wasn’t hot enough or the ice cream wasn’t frozen solid going in. Make sure the oven is fully preheated to 220°C/425°F before the cake goes in, and don’t skip the final freeze after assembling.
- Meringue slides off the ice cream: The ice cream surface was too smooth and cold for the meringue to grip. Rough up the surface of the ice cream dome slightly with a spoon before spreading the meringue, and work quickly so it doesn’t start to sweat.
- Sponge is soggy at the base: The sponge wasn’t fully cooled before assembly, or the ice cream was slightly melted when placed on it. Both release moisture into the cake. Cool the sponge completely on a wire rack and make sure the ice cream is firm.
- Meringue peaks burn before the base browns: The peaks are thin and catch heat fast. Either smooth the meringue into a more even layer, or watch it closely and pull it at three minutes rather than five — golden tips are fine, black tips are not.
Classic Baked Alaska
Ingredients
Ice Cream Layer
- 1 litre premium vanilla ice cream softened slightly for easy molding
Sponge Cake
- 100 grams all-purpose flour
- 100 grams granulated sugar
- 3 large eggs room temperature
- 1 teaspoon vanilla extract
- 40 grams butter melted and cooled
Meringue
- 4 large egg whites
- 200 grams caster sugar
- 1 teaspoon cream of tartar
Instructions
- Begin by lining a bowl or mold with plastic wrap. Fill with slightly softened premium vanilla ice cream, smoothing the surface. Freeze until firm, about 2 hours.
- For the sponge, preheat the oven to 180°C/350°F. Line a baking sheet with parchment paper.
- In a bowl, whisk together the eggs and granulated sugar until pale and thickened. Gently fold in the flour and vanilla extract. Lastly, blend in the melted butter.
- Spread the batter evenly on the prepared sheet and bake for about 10 minutes or until light golden. Let it cool completely on a wire rack.
- Cut the cooled sponge to fit as the base for the ice cream mold. Place it back into the freezer with the mold.
- To make the meringue, whisk egg whites and cream of tartar until soft peaks form. Gradually add sugar, whisking to stiff, glossy peaks.
- Invert the ice cream and sponge onto a baking tray. Peel off the plastic, completely covering with meringue to seal in ice cream. Swirl for decorative peaks.
- Bake in a preheated oven at 220°C/425°F for 3-5 minutes until meringue is golden.
- Serve immediately with a sharp knife to slice through the layers.

Your questions, answered
Can I make Baked Alaska the day before?
Yes — assemble it fully with the meringue and freeze it overnight, then bake it straight from the freezer when you’re ready to serve. The meringue holds up well frozen and actually benefits from the extra chill time before going into the hot oven.
Do I need a kitchen torch, or does the oven work?
The oven works perfectly well for this recipe — 3 to 5 minutes at 220°C/425°F gives you an even golden color all over. A kitchen torch is faster and gives you more control over browning, but it’s not required.
How do I know when the meringue is done?
Pull it when the peaks are golden brown and the surface has a dry, set look — usually around 3 to 4 minutes. Don’t go by time alone; ovens vary, so start checking at the 3-minute mark.
Can I use a different size or shape mold for the ice cream?
Any bowl or container works as long as you can line it with plastic wrap and unmold it cleanly. Just cut your sponge base to match the opening of whatever mold you use so there are no gaps around the edges.
What if my meringue won’t reach stiff peaks?
The most common cause is a trace of fat in the bowl or on the whisk — even a small amount of egg yolk will prevent the whites from whipping up properly. Wipe your bowl and beaters with a little lemon juice or white vinegar before you start, and make sure no yolk got into the whites when you separated the eggs.
