Recipe Information
Ingredients
- 2 sheets Puff pastry sheets
- 80 grams Vanilla protein powder
- 40 grams Cornstarch
- 100 grams Granulated sugar
- 600 milliliters Whole milk
- 1 teaspoon Vanilla extract
- 4 pieces Egg yolks
- 5 grams Gelatin powder
- 2 tablespoons Water
- 25 grams Butter
- 200 milliliters Whipped cream
- 10 grams Icing sugar for dusting
Instructions
Preheat your oven to 200°C (392°F).
Place the puff pastry sheets on lined baking trays and prick them all over with a fork to prevent excessive rising.
Bake the pastry sheets for about 15 minutes or until golden and crispy. Allow them to cool completely.
In a small bowl, mix the gelatin powder with 2 tablespoons of cold water and set aside to bloom.
In a large saucepan, combine the protein powder, cornstarch, and granulated sugar.
Gradually whisk in the milk and egg yolks until smooth.
Place the saucepan over medium heat and cook the mixture, whisking continuously, until it thickens and comes to a gentle boil.
Remove from heat and stir in the bloomed gelatin, vanilla extract, and butter until fully incorporated.
Allow the custard to cool slightly, then fold in the whipped cream until well combined.
Trim the edges of the puff pastry sheets to fit a square or rectangular dish if necessary.
Place one pastry sheet on the bottom of the dish, spread the custard evenly over it, and top with the second pastry sheet.
Refrigerate for at least 3 hours or until set.
Once set, dust with icing sugar, slice, and serve.
