Molten Chocolate Lava Cake

Ingredients

Equipment Needed

• •Six 6-ounce ramekins or custard cups
• •Double boiler or heatproof bowl over saucepan
• •Electric hand mixer or stand mixer
• •Rubber spatula
• •Fine-mesh sieve for sifting and dusting
• •Rimmed baking sheet
• •Thin-bladed knife for unmolding

Instructions

1. 1

   Prepare the ramekins

   Generously butter six 6-ounce ramekins, working the butter into every crevice and up the sides. Dust each with cocoa powder, rotating the ramekin to coat completely, then tap out the excess. This cocoa coating creates the thin, delicate crust that shatters when you press your spoon through. Place the prepared ramekins on a baking sheet for easy transport.

   The butter must be thorough. Any bare spots become sticking points that tear your cakes when you unmold them. Cold butter from the refrigerator works best because it stays where you put it.
2. 2

   Melt chocolate and butter

   Combine the chopped chocolate and butter in a heatproof bowl set over a pot of barely simmering water. The bottom of the bowl should not touch the water. Stir occasionally with a spatula until completely smooth and glossy, about four minutes. The mixture should be warm but not hot. Remove from heat and let cool for five minutes while you prepare the eggs.

   A microwave works too: heat in 30-second bursts, stirring between each, until smooth. The double boiler gives you more control, but both methods produce identical results.
3. 3

   Whip eggs to ribbon stage

   In a large bowl, combine the whole eggs, egg yolks, sugar, salt, and vanilla. Beat with an electric mixer on medium-high speed for four to five minutes until the mixture triples in volume and falls from the beaters in thick, pale ribbons that hold their shape on the surface for several seconds before dissolving. This aeration is essential. It builds the structure that allows a thin cake layer to form around that molten center.

4. 4

   Fold chocolate into eggs

   Pour the cooled chocolate mixture over the whipped eggs. Using a large rubber spatula, fold gently but decisively, cutting down through the center, sweeping along the bottom, and folding over. Rotate the bowl a quarter turn and repeat. Continue until no streaks remain, about fifteen strokes. You're preserving the air you just whipped in.

5. 5

   Add flour

   Sift the flour over the batter. Fold it in with the same gentle technique, just until the flour disappears. The batter will be glossy, thick, and mousse-like. Do not overmix. The moment you stop seeing white specks, stop folding.

   Sifting isn't fussiness here. It breaks up clumps that would create pockets of raw flour in your finished cake. Ten seconds of sifting prevents a ruined dessert.
6. 6

   Fill ramekins

   Divide the batter evenly among the prepared ramekins, filling each about three-quarters full. The batter will mound slightly in the center. Use a small offset spatula or the back of a spoon to smooth the tops. At this point, you can refrigerate the filled ramekins for up to 24 hours or freeze for up to a month.

   A kitchen scale makes portioning foolproof. Weigh your total batter and divide by six. Each ramekin should hold roughly 100 grams.
7. 7

   Bake to the crucial moment

   Preheat your oven to 425°F. Bake the cakes on the center rack for 12 to 14 minutes. The edges will be set and slightly pulled away from the ramekin sides, the tops will look puffed and dry with fine cracks forming, but the center will jiggle like barely set custard when you shake the pan gently. This is the moment. Remove immediately.

   If baking from refrigerated, add 2 minutes. From frozen, add 4 to 5 minutes. Every oven varies. The first time you make these, watch them like a nervous parent. By the third batch, you'll know your oven's timing.
8. 8

   Rest and unmold

   Let the cakes rest in their ramekins for exactly one minute. No longer. Run a thin knife around the edge of each cake, pressing against the ramekin rather than the cake. Invert a dessert plate over the ramekin, flip both together, and lift the ramekin straight up. The cake should release cleanly, standing proud with its cracked dome now facing down.

9. 9

   Serve immediately

   Dust with powdered sugar through a fine sieve if desired. Add a scoop of cold vanilla ice cream or a dollop of softly whipped cream beside each cake. Serve within thirty seconds of unmolding. Instruct your guests to break through the top immediately with their spoons. The molten chocolate should flow out in a glossy, viscous pool. This is the moment you've been working toward.

Chef Tips

• •The quality of your chocolate determines everything. Use something you would happily eat straight from the bar. Bittersweet in the 60 to 70 percent cacao range provides the ideal balance of intensity and sweetness. Chocolate chips contain stabilizers that prevent proper melting.
• •Room temperature eggs whip to greater volume. Cold eggs straight from the refrigerator will work, but you'll need an extra minute of beating to reach the ribbon stage.
• •If a cake refuses to unmold, run your knife around it again and give the bottom of the ramekin a firm tap before lifting. The cocoa coating should release it. If you're still struggling, serve it in the ramekin with no apology. It tastes exactly the same.
• •A cold accompaniment is essential. The temperature contrast between molten chocolate and frozen ice cream or cold whipped cream heightens every sensation. Do not skip this.
• •For deeper flavor, add a pinch of instant espresso powder to the melted chocolate. It doesn't make the cake taste like coffee. It makes the chocolate taste more like chocolate.

Advance Preparation

• •Filled ramekins can be covered with plastic wrap and refrigerated for up to 24 hours before baking. This makes them ideal for dinner parties. Prepare them the morning of or even the night before.
• •For longer storage, freeze the filled ramekins until solid, then wrap each in plastic and store for up to one month. Bake directly from frozen, adding 4 to 5 minutes to the baking time.
• •The batter cannot be stored unbaked. Once made, it must go into ramekins immediately.
