A baked Alaska is all about contrast: warm, golden meringue on the outside, frozen coffee ice cream in the middle, and a soft chocolate cake underneath. This version takes a little planning, though none of the individual steps are difficult.

The easiest way to handle it is to spread the work across two days. Make the ice cream first, bake the cake once the ice cream is firm, then save the meringue and final assembly for serving time.

Baked Alaska Is Easier with a Make-Ahead Plan

The dessert looks dramatic because three separate components come together at once. In practice, most of the work happens well before it reaches the oven.

Start with the coffee ice cream, since it needs at least 5 to 6 hours to freeze into a solid dome. Overnight is better. The chocolate cake can also be baked up to a day ahead, then kept covered once it has cooled completely.

Only the meringue needs to be made close to serving time. Before assembling, have the baking sheet, spoon or piping bag, hazelnuts, and cooled cake ready. Once the ice cream leaves the freezer, work steadily. A firm dome and organized counter make the final stage much less stressful.

Ingredients for Chocolate Hazelnut Baked Alaska

The ice cream begins as a cooked custard made with whole milk, heavy cream, egg yolks, sugar, and instant coffee. Instant coffee works well here because it dissolves evenly into the hot dairy and gives the custard a clear coffee flavor without adding liquid.

For the cake, you’ll need butter, sugar, eggs, all-purpose flour, baking powder, and melted dark chocolate. I prefer chocolate with about 70% cocoa. It keeps the cake rich without making the whole dessert overly sweet.

The topping uses egg whites, sugar, cream of tartar, and roasted hazelnuts. Cream of tartar helps the whipped whites hold their structure, which matters when the meringue has to cover a frozen dome. The hazelnuts go into the meringue and over the top, adding a little crunch against the soft cake and smooth ice cream.

Preparing the Coffee Ice Cream Core

Chill the ice cream maker bowl according to its instructions before starting. Some machines need a full day in the freezer, so check that first.

Heat the milk and cream over medium heat. As soon as small bubbles appear around the edge and the mixture begins to simmer, take it off the heat and stir in the instant coffee. There’s no need to boil it.

In a large heatproof bowl, whisk the egg yolks and sugar for about 2 minutes. The mixture should become paler and slightly thicker. Pour the hot coffee mixture into the yolks very slowly while whisking the whole time. This gradual warming helps keep the eggs smooth rather than scrambled.

Return everything to the saucepan and cook over medium heat for 5 to 6 minutes, stirring constantly. Scrape across the bottom and into the corners of the pan. The custard is ready when it lightly coats the back of a spoon and a finger drawn through it leaves a clear line.

Strain the custard through a fine-mesh sieve, then refrigerate it for at least 30 minutes. Once cool, churn it until it reaches a soft-serve texture.

Line an 8-inch freezer-safe bowl with two layers of plastic wrap, leaving plenty hanging over the sides. Spoon in the ice cream, smooth the surface, and fold the plastic over it. Freeze for at least 5 to 6 hours. The center should feel completely hard before assembly.

Baking the Chocolate Cake Base

Heat the oven to 350°F and grease an 8-inch round cake tin with butter. Line the bottom with parchment paper so the cake releases cleanly later.

Beat the butter and sugar until the mixture looks lighter and creamy. A whisk or wooden spoon works, though an electric mixer makes this quicker. Add the eggs and beat until the batter looks even.

Mix in the flour and baking powder only until no dry streaks remain. Overmixing at this stage can make the cake firmer than it needs to be. Fold in the melted dark chocolate, scraping the bottom of the bowl so the color stays uniform.

Transfer the batter to the prepared tin and level the surface. Bake for about 30 minutes. Check the center with a toothpick; it should come out clean or with a few dry crumbs.

Let the cake cool completely in its tin on a wire rack. Don’t rush this part. Even slight warmth can soften the ice cream during assembly. Once cool, cover the cake and keep it at room temperature until needed.

Whipping a Stable Hazelnut Meringue

Make the meringue only when the cake is cool and the ice cream dome is fully frozen. Add the egg whites to a clean, dry bowl and whisk until soft peaks form. At this stage, the peaks should bend over when you lift the whisk.

Keep whisking while adding the sugar slowly. A spoonful at a time works better than pouring it in all at once. If the sugar goes in too quickly, the mixture can stay grainy and struggle to build enough volume.

Add the cream of tartar and continue whisking until the meringue looks glossy and holds firm peaks. When the whisk is lifted, the tip should stand upright instead of folding over. Rub a little meringue between two fingers. It should feel mostly smooth, not sandy.

Fold half of the roasted hazelnuts in with a spatula. Use broad, gentle strokes so you don’t knock out too much air. The finished meringue should be thick enough to cling to the frozen ice cream without sliding down the sides.

Assembling and Baking the Baked Alaska

Heat the oven to 425°F before taking the ice cream from the freezer. Place the cooled cake on a flat cookie sheet or rimmed half-sheet pan, with the flat side facing up.

Unfold the plastic wrap from the ice cream, lift the frozen dome from its bowl, and invert it onto the center of the cake. Peel away the remaining plastic immediately.

Cover the ice cream and exposed cake with meringue, working from the bottom upward. Spread it all the way down to the baking sheet so there are no gaps. That complete coating is what slows the oven heat from reaching the frozen center.

Shape peaks with the back of a spoon, or pipe the meringue if you prefer a neater pattern. Sprinkle the remaining hazelnuts over the surface. Work at a steady pace. If the ice cream starts to soften, return the whole dessert to the freezer for a few minutes before baking.

Bake for 7 to 8 minutes, just until the peaks turn golden and the hazelnuts smell lightly toasted. Watch closely near the end because the color can deepen quickly.

Serve the baked Alaska as soon as it comes out of the oven. Use a sharp knife dipped in hot water, then wiped dry, to cut clean slices through the meringue, frozen coffee ice cream, and chocolate cake.

A Dessert Worth Planning Ahead For

The key to this baked Alaska is timing rather than complicated technique. A solid ice cream dome, a completely cooled cake, and firm meringue make the final assembly much easier.

Prepare the frozen and baked layers in advance, then save the last few minutes for covering and browning. When it reaches the table, those contrasting layers make the extra planning feel worthwhile.
