Ingredients:
- 125ml water
- 125ml whole milk
- 115g unsalted butter, cubed
- 5g granulated sugar
- 2g salt
- 150g gluten-free all-purpose flour blend (containing xanthan gum)
- 220g large eggs (approx. 4 to 5), room temperature and lightly beaten
- 500ml whole milk (for filling)
- 10ml vanilla bean paste
- 4 large egg yolks
- 40g cornstarch
- 100g granulated sugar (for filling)
Instructions:
- Combine water, milk, butter, 5g sugar, and salt in a heavy-bottomed saucepan over medium heat. Bring to a rolling boil until butter is completely melted.
- Add the gluten-free flour all at once. Stir vigorously with a wooden spoon for about 2 minutes until a cohesive dough ball forms and a thin film develops on the bottom of the pan.
- Transfer the dough to a mixer bowl. Beat on low speed for 2 minutes to allow steam to escape and the dough to cool slightly.
- Gradually add the beaten eggs one tablespoon at a time, incorporating fully after each addition. Stop adding eggs when the batter becomes glossy and forms a 'V' shape when lifted with the paddle.
