๐ What Is Napoleon Cake?
Napoleon cake, also known as โNapoleon Torteโ or Russian mille-feuille, is a multi-layered dessert made with thin, flaky pastry and a velvety custard or pastry cream. Unlike the French mille-feuille, which often has three layers, the Russian version usually has 6โ12 thin layers and is left to chill overnight so the cream soaks into the pastry, resulting into a sliceable, melt-in-your-mouth experience.
This cake is a beloved classic in Eastern Europe and is often made for special occasions like New Yearโs, birthdays, and weddings.
You’ll Need
- Puff Pastry โ Use frozen puff pastry sheets or blocks. Make sure theyโre fully thawed before rolling. Roll each piece thinly for crisp, delicate layers that soften perfectly once assembled with cream.
- Flour (for dusting) โ Helps prevent sticking when rolling out the pastry. Just a light dusting is enough.
- Sweetened Condensed Milk โ Brings sweetness and a creamy texture to the filling. No need for extra sugarโthis does the job beautifully.
- Heavy Whipping Cream โ Whip until stiff peaks form. It gives the filling a light, airy texture and helps it hold its shape between layers.
- Fresh Berries (strawberries & blueberries) โ Optional, but great for a fresh and colorful garnish. Slice or halve them for easy decorating.
- Powdered Sugar โ Adds a simple, elegant finish. Dust just before serving for the best look.
How to Make Napoleon Cake
Prep the pastry: Roll out chilled puff pastry into thin sheets and cut into rectangles. Prick them with a fork to prevent too much puffing.
Bake the layers: Bake the pastry until golden and crisp. Let them cool fully. Save some offcuts for decorating.
Make the cream: Whip the heavy cream to soft peaks, then beat in sweetened condensed milk until thick and glossy.
Assemble the cake: Layer pastry and cream, one after the other. Press lightly to keep it even.

How to Store Napoleon Cake
Napoleon cake should be stored in the refrigerator, tightly covered or in an airtight container.

Avoid freezing, as the whipped cream filling can separate and the pastry may lose its crispness.

Napoleon Cake Recipe
Ingredients
Napoleon Cake Layers
- 2 pounds puff pastry blocks, thawed according to package instructions
- ยผ cup all-purpose flour, for dusting
Cream for Napoleon Cake
- 1 (14-ounce) can sweetened condensed milk
- 2ยฝ cups heavy whipping cream, 35% fat
For Cake Decoration
- 5 fresh strawberries, halved or sliced
- 2 tablespoons fresh blueberries
- 1 tablespoon powdered sugar
Instructions
- Set your oven to 400 ยฐF (200 ยฐC) ยฐF. Pop the rack in the middle so everything bakes evenly.
- Make sure your puff pastryโs chilled but pliableโovernight in the fridge is perfect, or let it sit on the counter for about 20 minutes if itโs still stiff.
- Cut each 1-pound block in half so youโve got four pieces. On a lightly floured piece of parchment paper, roll each piece until itโs nice and thin.
- Cut each sheet into two 12โณร8โณ rectanglesโyouโll have eight total. Keep those offcuts on the parchment; they turn into our tasty topping. Give every rectangle a good prick with a fork (or lightly drag a pizza cutter over it) so it wonโt puff up too much.
- Lay two sheets (parchment and all) on your baking sheet and bake for about 9โ10 minutesโjust until theyโre gently golden. Donโt wander off! Transfer to a wire rack to cool, then repeat with the rest.
- In a cold bowl, pour in 2ยฝ cups of cold heavy cream. Whip on medium speed until you see soft peaks. Pour in the entire 14-ounce can of sweetened condensed milk, then keep whipping until those peaks are stiff and glossy.
- Place one crisp pastry sheet on your serving platter. Slather on a generous layer of the cream, then top with another sheet. Press down lightly and repeat until youโve used six sheetsโcream between each layer, of course.
- Crumble the last baked sheet and all those trimmings into tiny bits. Stir in 1 tablespoon of powdered sugar, then press the crumbs all over the top and sides of your cake.
- Arrange 4โ5 halved fresh strawberries in a circle around the top edge. Scatter 2 tablespoons of fresh blueberries in the center. Dust the fruit and edges with a light sprinkle of powdered sugar for a finishing touch.
- Cover your cake and let it rest in the fridge for at least 1โ2 hours. This little nap makes it slice like a dream. Grab a sharp knife, cut yourself a generous piece, and enjoy every flaky, creamy bite!

I made this Napoleon cake for my momโs birthday, and it was a huge hit! The cream was so light and perfectly sweet, and the layers softened beautifully overnight. Honestly, it tasted even better the next day. Will definitely be making this again for the holidays!
