Custard-Filled Éclairs Recipe with Homemade Choux

These classic éclairs use the two components in the original recipe: a water-and-butter choux pastry and a milk-based vanilla custard. Cook the flour briefly in the hot water and butter until it forms a smooth ball, then let it cool before beating in the eggs one at a time. The batter should be glossy and hold its piped shape. Bake the fingers at a higher temperature first, then lower the oven so the shells dry without burning. Meanwhile, cook the egg-yolk custard until it thickens and bubbles, then chill it promptly in a shallow covered bowl. Fill the shells only when both components are cool. This keeps the crust from softening too early and makes it easier to judge whether the cream is thick enough to stay inside.

Helpful tips

• Cook the flour paste until it leaves a film on the pan.
• Let the dough cool enough that eggs do not scramble.
• Do not open the oven door while the shells rise.
• Cool custard promptly and fill shells close to serving time.

Serving ideas

• Dust with a little icing sugar before serving.
• Add a thin line of melted chocolate on top.
• Serve with coffee.
• Offer with fresh berries on the side.

Variation

The original suggests stirring 50 g dark chocolate into the warm custard for a chocolate filling.

Make ahead

Bake the shells and cook the custard in advance; keep the chilled custard separate and fill the shells close to serving.

Food safety

Cook egg-yolk custard until thick and bubbling, then cool it promptly and refrigerate filled pastries.

Storage

Refrigerate filled éclairs immediately and use within 2 days. Keep unfilled shells dry and separate until needed.
