Questions

What is Napoleon Cake?

A classic layered cake featuring thin, crispy pastry sheets filled with rich, velvety custard cream and coated in fine pastry crumbs. This reference files it under Russian dessert: made on the stovetop and in the oven, rated hard and about 100 minutes start to finish.

Can I skip chilling the dough for Napoleon Cake?

Step 3 reads: "Divide dough into equal portions and chill in the refrigerator for 1 hour." Not without a cost. The rest in step 3 firms the fat and relaxes the gluten, so the dough holds its shape and bakes up tender instead of spreading or shrinking.

Is there a substitute for cornstarch in Napoleon Cake?

The entry for Napoleon Cake calls for 4 tbsp cornstarch. In its place: Use twice as much all-purpose flour and cook it a few minutes longer, or the same amount of arrowroot or tapioca starch.

Can I make Napoleon Cake gluten-free?

Yes. The gluten in Napoleon Cake is 4 cups all-purpose flour, sifted. Swap the flour for a 1-to-1 gluten-free baking blend (where it only thickens a sauce, half as much cornstarch also works). Everything else proceeds as written.

Is Napoleon Cake vegan?

No, though it is vegetarian. What keeps it from vegan is 2 cups unsalted butter, chilled, diced, 4 cups whole milk, 1 cup unsalted butter, softened and 2 egg, beaten. For fully plant-based entries, see the vegan dessert collection.

Does Napoleon Cake contain eggs?

Yes: 2 egg, beaten and 6 egg yolks, whisked. The full allergen list for this entry is gluten, dairy and eggs. Packaged ingredients vary by brand, so check labels if the allergy is serious.

Can I start Napoleon Cake the day before?

Yes. Step 3 is a built-in pause of 1 hour: "Divide dough into equal portions and chill in the refrigerator for 1 hour." Do everything up to that point ahead of time and pick up at step 4 when you are ready to finish.
