Cream Puffs with Custard Filling
๐งย Instructions
-
Mix Dry Ingredients:ย In a medium saucepan, whisk together the sugar, cornstarch, and salt.
-
Add Wet Ingredients:ย Whisk in the egg yolks until the mixture is smooth and pale. Gradually whisk in the milk until everything is well combined.
-
Cook:ย Place the saucepan over medium heat. Cook, whisking constantly, until the mixture thickens and begins to bubble, about 5-7 minutes. Let it bubble for 1 full minute while whisking; this ensures the cornstarch is fully cooked.
-
Finish:ย Remove from heat. Immediately whisk in the butter and vanilla extract until smooth.
-
Chill:ย Pour the custard into a clean bowl. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Refrigerate for at least 2 hours, or until completely cold and set.
Part 2: Make the Choux Pastry Puffs
-
Preheat Oven:ย Preheat your oven to 425ยฐF (220ยฐC). Line a large baking sheet with parchment paper.
-
Boil Liquids:ย In a medium saucepan, combine the water, butter, and salt. Bring to a rolling boil over medium-high heat.
-
Add Eggs:ย Transfer the dough to a mixing bowl. Using a hand mixer or stand mixer on medium speed, beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. The dough will look slick at first but will become thick, smooth, and glossy once all eggs are added.
-
Pipe & Bake:ย Spoon or pipe the dough into 1.5-inch mounds on the prepared baking sheet, spacing them about 2 inches apart.
-
Bake:ย Bake for 15 minutes at 425ยฐF. Without opening the oven door, reduce the temperature to 350ยฐF (175ยฐC) and bake for another 15-20 minutes, until the puffs are golden brown, puffed, and sound hollow when tapped.
-
Cool:ย Immediately transfer the puffs to a wire rack. Use a sharp knife or toothpick to poke a small hole in the side of each puff to let the steam escape. This prevents them from getting soggy. Let them cool completely.
Part 3: Assemble the Cream Puffs
-
Fill:ย Once the puffs and custard are completely cool, slice the puffs in half horizontally or use the pre-poked hole to fill them.
-
Pipe:ย Spoon the chilled custard into a piping bag fitted with a round or star tip. Pipe the custard into the bottom half of each puff and replace the top.
๐ย Pro Tips & Storage
-
Make Ahead:ย The unfilled baked puffs can be stored in an airtight container at room temperature for 1 day, or frozen for up to 3 months. Thaw and crisp them up in a 300ยฐF (150ยฐC) oven for 5-10 minutes before filling.
-
Filling Variations:ย Add a tablespoon of liqueur (like Grand Marnier or Amaretto) to the custard, or fold in softly whipped cream for a lighter texture.
-
For Crispy Puffs:ย Ensure your oven is fully preheated and avoid opening the door during the initial baking stage.
-
Serve Immediately:ย For the best texture, fill the puffs no more than a few hours before serving to keep the pastry crisp.
