Dark Chocolate Molten Lava Cake

Prepare six 6-oz ramekins by brushing insides generously with softened butter

Dust buttered ramekins with cocoa powder, tapping out excess

This ensures clean release and adds chocolate flavor to edges

Refrigerate prepared ramekins while making batter

Place finely chopped dark chocolate and butter in heatproof bowl

Microwave in 30-second intervals, stirring between each, until completely melted and smooth

Alternatively, melt over double boiler

Let chocolate mixture cool slightly while preparing eggs

In a large bowl, whisk together whole eggs, egg yolks, granulated sugar, and brown sugar

Whisk vigorously for 2–3 min until mixture is pale, thick, and ribbony

This incorporates air for a lighter texture

Whisk in vanilla extract, espresso powder, and salt

The espresso enhances chocolate flavor without adding coffee taste

Pour slightly cooled chocolate mixture into egg mixture

Whisk gently until completely combined and glossy

Sift flour and cocoa powder over chocolate mixture

Fold in gently with spatula until just combined - don't overmix

A few small streaks of flour are fine

Divide batter evenly among prepared ramekins, filling about 3/4 full

Tap ramekins gently on counter to release air bubbles

Cover each ramekin tightly with aluminum foil, crimping edges to seal

Preheat sous vide water bath to 176°F (80°C)

Carefully place covered ramekins in water bath

Ensure water comes at least halfway up sides of ramekins

Cook for 45 min until edges are set but centers remain molten

The cakes should look set around edges but still jiggle in center

Remove ramekins from water bath carefully using tongs

Let rest for 2–3 min - the centers will remain liquid

Run a thin knife around edge of each ramekin to loosen

Place a dessert plate upside down over each ramekin

Using oven mitts, quickly flip ramekin and plate together

Gently lift ramekin - cake should release cleanly

Dust warm cakes with powdered sugar

Garnish with fresh raspberries and mint leaves

Serve immediately with vanilla ice cream and whipped cream

Drizzle plate with chocolate sauce for elegant presentation

The molten center will flow when first cut - serve right away
