Step 1

Preheat to 360F, butter an 8 inch cake pan and line with parchment paper.

Step 2

Chop chocolate and butter then place in a bowl over a pot of simmering water and melt stirring occasionally. Sift in the cocoa powder, whisk in the sugar, salt, espresso powder and eggs mix very well. You may add a teaspoon of vanilla at this point but it is optional.

Step 3

Pour into prepared pan and bake at 360f for 22-25 minutes. The top will have a crust and the edge will have risen and set.

Step 4

Allow to cool in pan for a few minutes then run a knife along the edge and invert onto a cake plate. Allow to cool then dust with powdered sugar, cocoa or cover in ganache. Top with berries and enjoy!
