Ingredients
Pastry Layers
- 2 pounds puff pastry blocks (thawed according to package instructions)
- ¼ cup all-purpose flour (for dusting)
- 1 tablespoon powdered sugar (for topping crumbs)
Cream Filling
- 1 (14-ounce) can sweetened condensed milk
- 2½ cups heavy whipping cream (35% fat), cold
Toppings
- 5 fresh strawberries (halved or sliced)
- 2 tablespoons fresh blueberries
Instructions
- Preheat Oven: Set your oven to 400 °F (200 °C) with the rack positioned in the middle to ensure even baking across the pastry sheets.
- Prepare Puff Pastry: Make sure your puff pastry is chilled yet pliable—overnight refrigeration is best, or let it sit at room temperature for about 20 minutes if still stiff.
- Roll Out Pastry: Cut each 1-pound block in half to create four pieces. On a lightly floured piece of parchment paper, roll each piece out thinly to prepare for baking.
- Cut and Prick Dough: Cut each rolled sheet into two 12″×8″ rectangles, yielding eight total rectangles. Keep the offcuts for topping later. Prick each rectangle thoroughly with a fork or lightly drag a pizza cutter over them to prevent excessive puffing during baking.
- Bake Pastry Layers: Place two pastry sheets (with parchment) on a baking sheet and bake for 9–10 minutes until they turn gently golden. Transfer baked sheets to a wire rack to cool. Repeat baking remaining sheets and offcuts similarly.
- Prepare Cream Filling: In a cold bowl, whip 2½ cups of cold heavy cream at medium speed until soft peaks form. Gradually add the entire can of sweetened condensed milk and continue whipping until stiff, glossy peaks develop.
- Assemble Cake: Place one cooled pastry sheet on your serving platter. Spread a generous layer of the whipped cream mixture over the sheet, then top with another sheet. Lightly press and repeat layering until six sheets with cream in between are stacked.
- Prepare Topping Crumbs: Crumble the last baked sheet along with all trimmings into small bits. Mix in 1 tablespoon powdered sugar, then press these crumbs evenly over the cake’s top and sides to create a textured coating.
- Decorate with Fresh Fruit: Arrange the halved strawberries in a circular pattern around the cake’s edge and scatter blueberries in the center. Lightly dust the arrangement and edges with powdered sugar for an elegant finish.
- Chill Cake: Cover the cake and refrigerate for at least 1–2 hours to let it set and enhance sliceability. Once chilled, slice and serve the flaky, creamy Napoleon Cake.
Notes
- Ensure puff pastry sheets are thin and well-pricked to avoid excessive puffing and achieve crisp layers.
- Use cold heavy cream and bowl for whipping to ensure maximum volume and stability.
- Chilling the assembled cake is essential for easier slicing and improved flavor melding.
- Fresh berries add a refreshing contrast but can be substituted with other fruits like raspberries or kiwi as desired.
- Store leftovers covered in the refrigerator and consume within 2 days for best texture and freshness.
