How to Make Gluten Free Mille-Feuille / Custard Slices

I finally made some mille-feuille / custard slices this morning 😍, using Jus Rol gluten free puff pastry + homemade pastry cream and a simple icing. 

Along with eclairs and proper Krispy Kreme style doughnuts, this was yet another classic dessert that was missing from my gluten free life (until now). I had been wanting to make these for AGES but for some reason I always assumed it would be impossible or way too much hassle…

And well, it turns out they’re actually not that difficult to make. You have to prepare the pastry cream in advance so it’s a bit time consuming in that sense, but otherwise it’s relatively simple. Well worth a try if it’s something you miss. 👍

P.S.: I highly recommend cutting the pastry into individual little rectangles BEFORE baking and assembling each mille-feuille separately. People usually bake large pastry sheets, assemble a large mille-feuille, refrigerate and then slice into portions… but to be honest I found that process a bit messy and difficult with GF pastry.

Directions

STEP 1 – MAKE THE PASTRY CREAM (IN ADVANCE):

  1. Add the milk and half of the sugar into a sauce pan and bring it to a light simmer on medium heat, stirring constantly.
  2. Whisk together the rest of the sugar, 2 egg yolks, cornflour and vanilla extract in a bowl, then pour some of the warm milk into it and whisk it all until well combined.
  3. Then pour the content back into the sauce pan and keep whisking, still on medium heat, until the pastry cream thickens. This should take about 1 minutes.
  4. Then stir in 1 tablespoon of butter.
  5. Pour the pastry cream into a bowl, cover with cling film and place in the fridge for a few hours or overnight. Note: to prevent a skin from forming on top, press the cling film directly against the surface of your pastry cream.

STEP 2 – COOK THE PASTRY:

  1. Take your pastry out of the fridge and let it rest for 10 minutes at room temperature before carefully unrolling it. This helps prevent cracks which can happen if the pastry is too cold (if it does, just fix the cracks by smudging them with your fingers).
  2. Slice the pastry sheet into several little mille-feuille size rectangles (you’ll need 3 layers for each).
  3. Poke the pastry all over with a fork to prevent the pastry from rising too much. Note: with ‘normal’ pastry, it’s recommended to place baking beads or another baking tray on top to prevent it from rising, but honestly this isn’t really a problem with gluten free puff pastry!
  4. Bake in a preheated oven (200C/392F) or about 15 minutes, until golden.
  5. Take it out of the oven and let it cool down completely before assembling your gluten free mille-feuille.

STEP 3 – MAKE THE ICING:

  1. Mix the icing sugar, salt and corn syrup together.
  2. Then add the milk slowly, one tsp at a time, until you reach the right consistency. Note: icing sugar absorbs liquids like crazy so it’s important to add the milk little by little.
  3. For the chocolate icing, just transfer a few tablespoons of the normal icing into a small bowl and add some cocoa powder.

STEP 4 – ASSEMBLE THE MILLE-FEUILLE:

Mille-Feuille are made with 3 layers of pastry: one at the bottom, a second one in between two layers of pastry cream and one at the top covered in icing.

  1. Let’s start with the top layer: cover each top layers with plain icing, spreading it evenly with a spatula or knife. Then add a few lines of chocolate icing (you can use a piping bag with a very small tip for this or do what I did: fold a small square of baking paper into a cone shape, add the chocolate icing and pipe it out). Then drag the lines into a V shape using the tip of a knife or a skewer (as seen in the pictures above). Clean up the sides and leave to dry.
  2. Cover the bottom layer in pastry cream, either by using a knife or a piping bag, place the middle pastry layer on top (pressing it gently) and add a second layer of pastry cream.
  3. Once the icing on the top layer has dried enough to handle, place on top of your mille-feuille.
  4. Then clean up the sides with a knife.
  5. Place the mille feuille in the fridge or freezer.

Enjoy!
