It’s a very simple Japanese-style Mont Blanc, chestnut cream dessert recipe. This snowy mountain look of the cake, following the meaning of the name in French, is the perfect winter dessert for Christmas holiday through daily snack. Store-bought mini tart shells and Bonne Maman chestnut preserve allow you to make Mont Blanc cake so easily. So thus, you will only need to prepare meringue cookies, melted chocolate and whipped cream. As the chestnut preserve contains a lot of sweetness, you won’t add any sugar to make chestnut cream. Meringue cookie can still be crispy for up to 3 days, so there is an option making them on another day for the rest of the steps.
What is Mont Blanc Cake in Japan
The reason I said this recipe, Japanese-style Mont Blanc, is because just I’ve never had traditional French or Italian Mont blanc cake. This recipe has been inspired from all that I’d eaten in Japan. There are various tastes: chestnut, chocolate, strawberry, sweet potato and green tea. it’s nationwide popular dessert that you can buy them any patisseries even at convenience stores just around the corner.
I think that we call “Mont Blanc” if it has some kind of base and top with spaghetti-like strings cream from a specific piping tip. Generally the base is a sponge cake, sliced rolled cake, meringue or tart. And under the chestnut cream, chestnut puree or a candied Chestnut is hidden with whipped cream.
My version of Mont Blanc layers from the bottom is :
- Mini tart shells
- Melted milk chocolate
- Chestnut preserve
- Whipped cream
- Meringue cookie
- Chestnut cream
This is one of the typical combination of Japanese Mont blanc. You can enjoy the delicious contrast of textures, along with rich flavorful chestnut cream. It’s very nice to pair with a cup of black coffee. I hope you have a good time in winter with this simple Mont blanc tart.
Mont Blanc Cake (Chestnut Desset)
- 12 store-bought mini tart shells

- Preheat oven to 100C (212F) and line a parchment paper on an over rack, then set aside.
- Crack the egg in a completely clean medium bowl and take out the egg yolk carefully with a spoon.
- Beat the egg white until firm peaks. Then gradually add the sugar as stirring each time and beat until the mixture is shiny. Remove the beater and add the almond flour (ground almonds), then mix softly with a rubber spatula.
- Transfer the meringue into a piping bag with a large tip (I used star shape). Then pipe about 0.7 inches (2 cm) diameter round onto the prepared paper sheet.
- Bake on 100C (212F) for 1 hour. After baking time, still leave the meringue in the oven door closed for 1 hour.

- Pour water in a large saucepan over high heat. Once water boiled, bring to simmer.
- Place the broken chocolate in the top of a double boiler or a heatproof bowl, and set over the saucepan. Stir occasionally until melted and smooth. Add 1-2 tbsp of milk (not in the ingredients) if the chocolate is too thick to brush.
- Brush a thick layer of the chocolate evenly inside the tart shells with a pastry brush.
- Pour the heavy whipping cream (double cream) into a large bowl and beat until firm peaks with an electric beater.

- Pipe the chestnut cream around the mini tower. Repeat the whole process for the rest of tart shells.
