Mansikkakakku is a traditional cake originating from Finland. The cake is usually made with a combination of strawberries, almonds, sugar, egg whites, salt, heavy cream, and vanilla. The egg whites are beaten with salt and sugar until stiff peaks form.
The almonds are ground and mixed with sugar, and the mixture is folded into the meringue. The meringue is baked and dried, then topped with whipped cream and strawberries. The process is repeated again with the same layers, and the cake is then chilled before serving.
