Begin by whisking a full cup of hot coffee into the chocolate cake batter.
Transfer the batter into the oven and bake it until your kitchen is filled with a delightful aroma.
Once the cake is warm, poke holes all over its surface.
Pour the smooth Nutella ganache into the holes of the cake.
In a separate bowl, melt dark chocolate with butter and a bit more Nutella.
Coat the crushed cornflakes in this buttery chocolate mixture.
Heap the coated cornflakes on top of the cake, spreading them out evenly.
Finish by sprinkling flaky sea salt on top to balance the sweetness, and serve while warm.
