Step 1

Preheat the oven to 400°F (200°C). Butter two 6-ounce ramekins or oven-safe mugs and place on a baking sheet. Set aside.

Step 2

In a medium bowl add in the butter and chocolate and gently melt either in the microwave or over a ban-marie.

Step 3

Once melted, whisk in the sugar, eggs, vanilla, and coffee until well combined.

Step 4

Lastly, stir in the flour and salt and mix until just combined. Evenly divide the batter between the two prepared dishes.

Step 5

Bake for 20-22 minutes or just until there is a jiggle in the center and the edges are set. A soft center ensures lovely, lava on the inside.

Step 6

Remove from the oven and allow to stand for 1 minute before carefully turning out each cake onto your serving dish. Enjoy straight away with some vanilla ice-cream.
