Ingredients explained

🥐 2 sheets of thawed puff pastry
🥛 950 ml whole milk
🍬 300 g white sugar
🌾 150 g wheat flour
🥚 8 eggs (separate yolks and whites)
🍦 3 teaspoons vanilla extract
🥃 2 tablespoons rum (optional)
🍶 500 ml cold whipping cream
❄️ 2 tablespoons icing sugar + extra for sprinkling

Note: You can substitute whole milk for non-dairy milk for a lighter version, or use gluten-free puff pastry if you prefer.

Equipment and preparation

What you need: A 23×33 cm rectangular mold, baking trays, spatula, large bowl and the Thermomix.

Previous preparation: Defrost the puff pastry and chill the cream before starting. Preheat the oven to 180°C to brown the puff pastry while you prepare the cream. Weighing and having all the ingredients ready makes the process much easier and avoids setbacks.

Tip: Having a sturdy spatula and a large bowl ready to mix the egg whites with the cream will save you time and stress.

Step by step instructions

Preheat the oven to 180°C. Place the puff pastry sheets on trays and bake for 10 minutes until golden. Reserve and let cool completely so that they do not become moist when adding the cream.

Pour 750 ml of milk into the glass and program 8-10 minutes, 100°C, speed 3 until it boils. This ensures that the milk is ready to receive the yolk and flour mixture without lumps forming.

In a clean glass, beat the yolks with the sugar for 2 minutes, speed 4 until you obtain a clear and airy cream. This will give volume and softness to the pastry cream.

Add the flour, vanilla extract, rum (optional) and the remaining 200 ml of milk. Mix 30 seconds, speed 5 until well integrated.

With the glass at speed 3, little by little pour the yolk mixture into the boiling milk through the hole in the lid. Program 8-10 minutes, 90°C, speed 4 until thickened. Stir constantly to avoid lumps.

Wash and dry the glass. Whip the egg whites until stiff peaks form, speed 3.5-4 for 3-4 minutes. Incorporate them into the cream with enveloping movements to keep the mixture aerated.

Place a sheet of puff pastry in the mold and pour the pastry cream. Spread evenly and refrigerate 1-2 hours until firm.

Whip the cold cream with icing sugar for 1-2 minutes until firm peaks are obtained. Spread over the cold cream.

Cut the second sheet of puff pastry into 15 squares and place it on the cream. Refrigerate at least 2 hours or overnight.

Before serving, sprinkle with icing sugar and cut into squares. Ready to enjoy and share! 🎉

Pro tips and troubleshooting

🌟 Secrets to success:

Whip the egg whites until stiff but not too stiff, so that the cream does not lose volume.
Use very cold milk and cream to get the right texture.
Stir constantly when adding the yolks to the hot milk to avoid lumps.
Refrigerate the dessert long enough for it to compact and be easy to cut.

❌ Common mistakes:

Problem: Liquid cream. Cause: Not thickening enough. Solution: Increase cooking by 1-2 minutes and check the temperature.
Problem: Wet puff pastry. Cause: Add hot cream to cold puff pastry without waiting. Solution: Let the puff pastry and/or cream cool before assembling.
Problem: Cream cut. Cause: Assembly with hot utensils or glass. Solution: Make sure the glass and cream are very cold.
