Easy Foolproof Chocolate Eclairs (1hour 20 mint)

Real eclairs are one of those pastries that feel impossible until you understand the order of operations: a crisp, hollow choux shell, a cool spoonable vanilla pastry cream, and a glossy chocolate ganache to dip the tops in. Tackle each part on its own and the whole thing turns out far more reliably than its reputation suggests. The payoff is a row of bakery-window eclairs that shatter at the first bite and ooze cold custard.

Why you'll love this

• A proper twice-cooked choux: dried on the stove, then baked hot-then-low so the shells puff tall and stay hollow
• Pastry cream cooked from scratch with yolks and cornstarch for a thick, pipeable vanilla custard that holds
• A two-ingredient chocolate ganache glaze that sets to a clean, shiny finish
• Broken into clear stages, so nothing has to happen all at once and each step has a cue to wait for

Key ingredients & swaps

• Water and butter — boiled together they melt the butter and create the steam that puffs the shells; bring to a full rolling boil before the flour goes in so the fat is fully melted and evenly dispersed
• All-purpose flour — the starch gelatinizes into the structure that traps steam and holds the puff; add it all at once and stir hard so it cooks into a smooth paste with no dry pockets
• Eggs — they are the leavening and the glue, beaten in one at a time until the paste forms a slow V-ribbon off the spatula; add the last egg gradually, as too much makes a loose batter that bakes flat
• Egg yolks and cornstarch — the thickeners for the pastry cream; the cornstarch lets the custard come to a boil without scrambling and sets it firm enough to pipe and hold
• Whole milk — the body of the pastry cream; whole milk gives a richer, silkier custard than low-fat, and heating it before tempering keeps the cooking quick and lump-free
• Semi-sweet chocolate and cream — melted into a ganache for the glaze; let it cool until just thickened before dipping so it coats in a glossy layer instead of running off

How to make it (step by step)

1. 

   1

   Cook the panade

   Bring the water, butter and salt to a full boil, then dump in all the flour at once and stir hard over the heat until it forms a smooth ball that pulls from the sides, about 1 to 2 minutes. You are gelatinizing the flour, so keep going until the dough looks glossy and a thin film coats the pan.

2. 

   2

   Beat in the eggs

   Let the dough cool a few minutes so it won't cook the eggs, then beat them in one at a time, fully blending each before the next. Stop when the paste is smooth, shiny and falls from the spatula in a slow V-shaped ribbon; if it runs off in a sheet you have added too much egg.

3.

   Pipe and bake tall

   Pipe even 4 to 5 inch logs onto parchment, spaced apart, and smooth any peaks with a wet finger. Bake at 425F (220C) for 10 minutes to spring them up, then drop to 375F (190C) for another 20 to 25 minutes until deeply golden and firm; do not open the door early or they will collapse.

   Dry out the shells

   Turn the oven off, crack the door and leave the eclairs inside for about 10 minutes so the insides finish drying. A pale or damp shell will go soggy once filled, so wait for a crisp, hollow, deep-gold shell before you take them out.

   Make the pastry cream

   Whisk the yolks, sugar and cornstarch smooth, then slowly pour in the hot milk while whisking to temper the eggs. Return it to the pan and cook, stirring constantly, until it bubbles and thickens, then keep it at a boil for about a minute so the cornstarch fully sets before you stir in the vanilla off the heat.

   Chill the cream

   Scrape the custard into a bowl and press cling film right onto the surface so it can't form a skin, then refrigerate until cold and thick. It needs to be properly chilled and stiff to pipe cleanly, so don't rush this.

   Fill the eclairs

   Once the shells are completely cool, poke two or three small holes in the base of each and pipe in the cold pastry cream until you feel it fill and a little pushes back. Filling from underneath keeps the tops smooth for glazing.

   Glaze and set

   Pour hot cream over the chopped chocolate, let it sit a minute, then stir to a smooth ganache and let it cool until just thickened. Dip the top of each eclair, let the excess drip off, and leave them to set before serving.
