Russian Cake Layers (Print Version)

# Ingredients:

→ Quick Puff Pastry

01 - 400g of unsalted butter, either frozen or chilled, diced up
02 - 2 eggs
03 - 160ml of cold water
04 - 780g of all-purpose flour, sifted
05 - 3 tbsp of vodka or cognac (you can swap it with water)
06 - 2 tbsp of white vinegar
07 - 1/8 tsp kosher salt

→ Egg-Yolk Custard Cream

08 - 7 egg yolks
09 - 1.5 liters of whole milk
10 - 400g of granulated sugar
11 - 1 tbsp of vanilla extract
12 - 85g of all-purpose flour, sifted
13 - 200g of unsalted butter

# Instructions:

01 - In a big bowl, whisk together 2 eggs and 1/8 tsp of kosher salt. Add 160ml of cold water, 2 tbsp of white vinegar, and 3 tbsp of vodka or cognac. Set it aside for now.
02 - Throw 400g of cold, cubed butter and 780g of sifted flour into a food processor. Blend until the mixture has little chunks about the size of peas.
03 - Pour the egg mixture into the butter-flour combo and keep pulsing until the dough starts clumping but isn't fully formed yet. Gently knead on a clean surface until it just comes together.
04 - Split the dough into 4 even pieces, flatten each into disks, and wrap them up tightly with plastic wrap. Pop them into the fridge for 1-2 hours, or keep them there for a few days if prepping ahead.
05 - Grab a saucepan and whisk 7 egg yolks with 400g of sugar. Add a splash of milk to blend easily, then mix in 85g of sifted flour until it's smooth with no lumps.
06 - Warm up 1.5 liters of whole milk over medium heat, stirring regularly to make sure it doesn't stick to the bottom. Use a microwave as a backup if you like.
07 - We've got to temper the eggs! Slowly drizzle the hot milk into the egg mixture while whisking non-stop so the eggs don't scramble.
08 - Set the pan back on medium heat and stir constantly as it cooks. Let it boil for about 2-3 minutes until thickened. Take off the heat, toss in 1 tbsp of vanilla extract and 200g of butter, and stir until smooth. Strain if needed.
09 - Crank the oven to 200°C. Roll each dough ball into a circle about 32cm wide. Prick them with a fork and bake on a tray for 5-7 mins until lightly golden. Trim each one to a 28cm circle while warm, keeping the scraps for later.
10 - Lay one baked layer on a plate, spreading a bit of cream to make it stick. Add 1/8 of the custard onto each layer, stacking them up. Cover the sides with cream and sprinkle the crumbled scraps on top. Chill before serving.

# Notes:

01 - You can enjoy the dessert fresh for a crisp bite or leave it in the fridge for 24-48 hours for a softer texture.
