1) Whisk the eggs until pale and lightly foamy. Don't overbeat the eggs.
2) Add the hot chocolate powder and whisk until fully dissolved.
3) Fold in the self‑raising flour gently until just combined into a rich batter.
4) Pour the batter into a 7" x 4.53 x 2.5" (20 × 11.5 × 5 cm) ceramic dish and cover tightly with tinfoil.
5) Steam over a gentle simmer for 13 to 15 minutes, depending on how fluffy or custardy you want it.
6) Let the steamed hot chocolate cake rest for 5 minutes before slicing — it sets as it cools. Fresh and lukewarm out of the oven is the best way to enjoy this cake!
