Gâteaux Mille-Feuille

Napoleon Pastry


Gâteaux Mille-Feuille  is the famous pastry that may be difficult to pronounce and some think it is difficult to prepare too!

Let’s first understand that Mille-Feuille (which technically is just the flaky pastry part) literally means 1000 layers and in English we simply call it Puff Pastry.

Napoleon Pastry

Although I will not be showing you how to make the actual puff pastry recipe here (at least not today, but we will get there!) we are going to construct it into a gâteaux with layers of pastry cream lightened with whipped cream, stack it high and then ice with poured fondant!

This classic French pastry is often mistakenly known as The Napoleon.

Most people do not know that a real deal Napoleon is actually an Italian dessert that “should be” made with almond paste (like frangipane) between the layers of puff pastry and not with pastry cream.

So let’s get our stories straight~ our geography recognized ~ and our recipes in order so we can dive into this decadent pastry ASAP!

  1. This looks light and delicious! I love the fact that can make this and can change it up a little with white chocolate (I’m allergic to chocolate). Thanks for a fabulous recipe that looks like you spent several hours in the kitchen making it! 🙂

  2. Hi Gretchen, nice recipe. My husband loves pastry cream and Puff Pastry or dulce de leche and Puff Pastry 🙂 so I think I would like to try this recipe for him. I have some questions regarding the cooking of the Puff Pastry… I have seen in some other places that the dust some powder sugar over the pastry before put it in the oven and then half baking process they also place another baking sheet on top of the pastry to prevent too much rising and crumbs. Do you think this is a good idea too? Thanks.

    1. Sure you can do that if you like. That was the standard practice in my bakery when we made dozens of full sheet pans of puff pastry at once. But here I didn’t find it was too much trouble to allow it to puff naturally then press them down. It is 2 ways to the same destination, you can do what you like better

  3. I have made this twice and my entire family cannot stop raving about how good and delicious this dessert is-Thankyou for your awesome recipes.

  4. Hi Gretchen!

    I am planning to make this tomorrow and freeze the fully assembled pastry without the icing (not serving till Friday). My question is, will the toasted almonds be soggy once it’s thawed? Sorry, if my question is silly. Thank you!

    1. Last question, for the toasted almonds and chocolate mixture did you use sweetened or unsweetened chocolate? I only have unsweetened chocolate.

  5. Hi Gretchen,

    I am really excited to try this recipe as it looks amaaaazing…… Any idea when the fondant will be back in stock?

    Thank you!

    1. Hi Thanks! It is awesome! I was not sure if I would buy more, I have to get a sense if people will buy it since I have to buy 50lbs at a time and I want to be able to move it fast, not have it sit around! Ill send an email to see if folks want to buy it! Thanks! (are you a Best baker? that way you can get the emails too?) (Sign up right column on the blog here)

  6. Hi Gretchen, I see that the fondant is back in stock, yippee!!! Just a quick question…..I will be making napoleans as part of a pastry display for my sister’s wedding in a couple of weeks. I wanted to freeze the napoleans until then. This may be a silly question but when should I apply the fondant, i.e. right away or after it comes out of the freezer in a couple of weeks? Thanks Gretchen!

  7. Hi Gretchen May the Lord Jesus continues blessing you!
    I follow you and I love every single recipe,thanks for cheering all of them with us! I love pastries and I will be making this recipe soon.
