Napoleon roll cake is a beautiful chilled dessert made from golden store-bought puff pastry strips layered with sweetened condensed milk cream, then rolled into a log and topped with crunchy crumbs.

Ingredients

Scale
  • 1 1/16 lb puff pastry (thawed)
  • 1 can (14 oz.) sweetened condensed milk
  • 7 oz. (200 g) unsalted butter (softened)

Instructions

  1. Preheat the oven to 400°F (200°C). Roll out the defrosted puff pastry to a thickness of about 1/6 inch (4 mm). Cut into thin, long strips: 9 inches (23 cm) long, 1/2 to 3/4 inch (1.5-2 cm) wide. Place the cut pieces on a baking sheet lined with parchment paper. Bake for about 15-20 minutes until slightly golden brown. Let the pastry puff cool down.
  2. Place the softened butter and sweetened condensed milk in a bowl and whisk with an electric mixer until well combined. The cream will be liquid enough.
  3. To assemble the cake, place two pieces of cling film on the work surface. One piece - along, the second - across to the first. Spread 2-3 tablespoons of the cream on the film. Reserve 2-3 puff strips for decoration, and divide the remaining strips into two parts.
  4. Place the first part of the puff strips over the cream and spread with 1/3 of the cream. Place the second layer of sticks on top and cover with another third of the cream.
  5. Using the free end of the cling film, roll the puff pastry into a tight roll. Close all ends of the film and roll the roll over the work surface to even out its shape. Place the rolled cake in the refrigerator for 3-6 hours, or better yet, overnight. Cover the remaining cream with plastic film and refrigerate.
  6. Remove the cake from the refrigerator and remove the cling film. Prepare the topping from the remaining puff sticks by rubbing them between your palms. Mix the cream with a rubber spatula to warm it up. Spread the cream over the roll and sprinkle it with crumbs.

Notes

  1. Make sure your butter is very soft to blend smoothly with the condensed milk. 
  2. Add 1/2 teaspoon of vanilla extract to the cream for a hint of vanilla flavor.
  3. Keep leftovers refrigerated for up to 2-3 days.
