Quick Recipe Version (TL;DR)
Quick Ingredients
- 4 large egg whites, room temp
- 200 g (1 cup) superfine or granulated sugar
- Pinch salt + 1/4 tsp cream of tartar or 1/2 tsp lemon juice
- 360 ml (1 1/2 cups) heavy cream, well chilled
- 30 g (2 tbsp) powdered sugar + 1 tsp vanilla
- 250 g sweetened chestnut spread (crème de marrons)
- 150 g unsweetened chestnut purée (or extra chestnut spread)
- 60 ml (4 tbsp) heavy cream + 15 g (1 tbsp) soft butter
- 1–2 tbsp dark rum or 1 tsp vanilla, pinch salt
- Powdered sugar for dusting; optional candied chestnuts or chocolate shavings
Do This
- 1. Heat oven to 110°C / 225°F. Line 2 baking sheets with parchment. Draw eight 7–8 cm (3 in) circles as guides.
- 2. Whip egg whites with salt and cream of tartar to soft peaks, then slowly beat in sugar until stiff and glossy. Pipe or spoon into meringue discs within the circles, slightly hollowing centers.
- 3. Bake 1 hour 30 minutes until crisp and dry. Turn oven off, crack door, and cool meringues inside at least 45 minutes.
- 4. Beat chestnut spread, chestnut purée, cream, butter, rum/vanilla, and salt until smooth and pipeable. Chill 30 minutes, then transfer to a piping bag fitted with a multi-hole or small round tip.
- 5. Whip cream with powdered sugar and vanilla to soft, billowy peaks. Keep chilled.
- 6. To assemble, mound whipped cream on each meringue, forming a small dome. Pipe chestnut cream in thin “vermicelli” strands all over to completely cover the cream.
- 7. Chill 30 minutes to set, dust with powdered sugar, garnish if desired, and serve within 2–3 hours.

Step-by-Step Instructions
Step 1: Prepare the pans and preheat the oven
Preheat your oven to 110°C / 225°F with a rack in the center. Line 2 baking sheets with parchment paper. Using a pencil and a 7–8 cm (3 in) round cookie cutter or glass as a guide, trace 4 circles on each sheet (8 circles in total), spaced a few centimeters apart. Flip the parchment over so the pencil marks are underneath but still visible through the paper. This gives you neat, evenly sized meringue bases.
Make sure your mixing bowl and whisk are completely clean and grease-free; any fat will prevent your egg whites from whipping properly. If you like, quickly wipe the inside of the bowl with a little vinegar or lemon juice and dry with a clean towel.
Step 2: Whip the meringue
Place the egg whites and salt in a large, clean mixing bowl (or the bowl of a stand mixer fitted with the whisk attachment). Begin whipping on medium speed until the whites are foamy. Add the cream of tartar or lemon juice and continue beating until soft peaks form.
With the mixer running on medium-high speed, add the sugar very gradually, about 1 tablespoon at a time, taking 2–3 minutes to add it all. Once all the sugar is in, increase speed to high and beat until the meringue is thick, glossy, and holds stiff peaks that stand up straight when you lift the whisk, about 3–5 minutes. Rub a tiny bit between your fingers; it should feel almost completely smooth, not gritty. If it is still gritty, beat another minute or two.
Step 3: Shape and bake the meringue bases
Transfer the meringue to a piping bag fitted with a large round or star tip (or simply use a spoon). Pipe or spoon the meringue onto the parchment, staying within each drawn circle. Aim for discs about 1.5–2 cm (3/4 in) high. With the back of a spoon, gently create a shallow indentation in the center of each disc, building up the sides slightly like a little nest. This hollow will later hold the whipped cream.
Bake at 110°C / 225°F for 1 hour 30 minutes, or until the meringues are dry to the touch and easily lift from the parchment. They should remain pale and not browned. Turn off the oven, crack the door open slightly (use a wooden spoon to prop it if needed), and let the meringues cool and dry inside the oven for at least 45 minutes, or until completely cool. This slow drying helps prevent cracks.
Step 4: Make the chestnut cream “vermicelli”
While the meringues bake or cool, prepare the chestnut cream. In a medium bowl, combine the sweetened chestnut spread, unsweetened chestnut purée, soft butter, heavy cream, rum or vanilla, and salt. Using a spatula or hand mixer on low speed, blend until completely smooth, thick, and creamy. You are aiming for a texture similar to thick frosting or smooth mashed potatoes: soft enough to pipe, but stiff enough to hold the thin strands.
If the mixture seems too thick to pipe, add an extra teaspoon or two of cream until it loosens slightly. If it seems too soft, chill briefly, then beat again. Taste and adjust with a little more rum or vanilla if you like a stronger flavor, or a tiny pinch more salt to sharpen the sweetness.
Cover the bowl and chill the chestnut cream for at least 30 minutes to firm up slightly before piping. When ready, transfer it to a piping bag fitted with a Mont Blanc tip (multi-hole), a small round tip (2–3 mm), or even a potato ricer if you have one dedicated to desserts.
Step 5: Whip the cream
Once the meringues are completely cool and you are getting close to serving time, make the whipped cream. In a chilled mixing bowl, combine the cold heavy cream, powdered sugar, and vanilla. Whip on medium-high speed until soft but stable peaks form. The cream should be thick and billowy, but still smooth and spreadable. Take care not to over-whip; if it starts to look grainy, stop immediately.
Keep the whipped cream refrigerated until you are ready to assemble the Mont Blancs. They are best assembled within an hour or two of serving so the meringue stays crisp.
Step 6: Assemble the Mont Blancs
Gently peel the cooled meringue discs off the parchment and place them on a serving platter or individual dessert plates. If any are uneven, you can carefully trim the bottoms with a serrated knife to help them sit flat.
Spoon or pipe a generous mound of whipped cream into the center of each meringue, creating a smooth dome shape about 4–5 cm (1 1/2–2 in) high. This dome will give the classic rounded Mont Blanc silhouette.
Next, take your piping bag filled with chestnut cream. Starting from the top of each whipped cream dome, pipe long, thin strands of chestnut cream, letting them fall naturally in loops and swirls down the sides, turning the plate as you go. Continue until the whipped cream is completely covered and each dessert looks like a little mountain of chestnut “vermicelli.” Do not worry about perfection; the charm of Mont Blanc is in the slightly messy, snowy look.
Chill the assembled Mont Blancs for about 30 minutes to set the shape and allow the flavors to meld.
Step 7: Garnish and serve
Right before serving, lightly dust the tops with powdered sugar to create a snowy effect. If you like, garnish each Mont Blanc with half a candied chestnut or a few dark chocolate shavings on top.
Serve immediately for the crispiest texture, or within 2–3 hours of assembly. Over time, the whipped cream will gently soften the meringue (which some people love), but they are at their most elegant when the base is still mostly crisp and the inside is soft and marshmallowy.
Pro Tips
- Use room-temperature egg whites. They whip to greater volume and more stability than cold whites, giving you lighter, taller meringues.
- Add sugar slowly. Gradual addition helps the sugar dissolve and prevents weeping or grainy meringues. Take a full 2–3 minutes to add all the sugar.
- Control chestnut cream texture. If your chestnut mixture is too stiff to pipe, add cream a teaspoon at a time. If too soft, chill briefly and re-whip. It should hold delicate strands without melting.
- Chill everything well before assembly. Cold whipped cream and slightly chilled chestnut cream are much easier to shape neatly and hold their form longer.
- No special Mont Blanc tip? A small round piping tip (or even the corner snipped off a sturdy piping bag) still works. Pipe multiple loose passes to mimic the look of fine chestnut “noodles.”
Variations
- Chocolate Mont Blanc: Add 2 tbsp unsweetened cocoa powder sifted into the chestnut cream and 30 g (2 tbsp) melted, cooled dark chocolate. Top with extra chocolate curls instead of candied chestnuts.
- Coffee-kissed Mont Blanc: Dissolve 1–2 tsp instant espresso powder in the cream used for the chestnut mixture, and add a touch of coffee liqueur. The subtle bitterness is wonderful with sweet chestnut.
- Family-style Mont Blanc: Instead of 8 small meringues, pipe a single large 20 cm (8 in) meringue disc, top with a big dome of whipped cream, and cover with chestnut strands to make a dramatic centerpiece dessert. Slice like a cake.
Storage & Make-Ahead
Meringues: Once fully cooled and dried, store the meringue bases in an airtight container at room temperature for up to 5 days. Add a small sachet of silica gel (food-safe) if you live in a humid climate, or keep them in the driest part of your kitchen.
Chestnut cream: The chestnut mixture can be made up to 3 days in advance. Store in an airtight container in the refrigerator. When ready to use, let it sit at room temperature for 15–20 minutes, then beat or stir briefly until smooth before transferring to a piping bag.
Whipped cream: For best texture, whip the cream the day you plan to serve. It can be stabilized for longer holding by adding 1–2 tsp instant vanilla pudding mix or 1 tsp powdered gelatin (bloomed and dissolved) if you need it to stay perfect for several hours.
Assembled Mont Blancs: Once assembled, they are best eaten within 2–4 hours. Store covered in the refrigerator. The meringue will gradually soften, but the dessert will still taste delicious the next day, just less crisp.
