Procedure:
This recipe makes around 2 cups of batter for up to 4 cakes, depending on your baking dish. Multiply the ingredients as needed for your desired number of portions.
Preheat the oven to 450F / 230C.
Generously butter (1-2 tbsp) and sugar four 6-8oz CHILLED baking tins or ramekins and refrigerate to set butter. Chilling them helps the butter to set quickly so that it grips the dish and doesn’t puddle in the bottom.
Melt the chocolate and butter together then add the instant coffee, cocoa powder, and vanilla and mix well. Set aside to cool.
**This step is key to the final texture of the batter and the cake**
In a mixing bowl, whisk the eggs, sugar, and salt until mixture “ribbons” and is doubled-ish in size**.
5-7 minutes on a stand mixer on medium to medium-high,
7-9 minutes with a hand mixer on medium to medium-high, or
9-11 minutes by hand. (Not recommended, LOL)
The batter has reached the “ribbon” stage when the batter runs from the coated beater to the bowl in a constant stream without breaking or dripping and looks like a ribbon hanging from the beater(s).
Gently pour the melted chocolate/butter mixture into egg mixture and mix to combine well.
Add flour to the chocolate and egg mixture and fold just until combined.
Divide evenly between the 4 baking tins or ramekins, about a 1/2 cup (4oz) each.
Make these up to three days ahead then portion, cover with plastic wrap and refrigerate until you are ready to bake them.
GAME PLAN: You need 12 minutes from the time you put them in the oven till you can plate and serve them.
Start preheating the oven when you serve the main course and put them in the oven when the main course is being cleared. SET A TIMER!! They will be ready by the time the table is set for dessert.
Cook for 7-8 minutes at 450F/232C. If they are cold when put in the oven, go the full 8 minutes and pull immediately. If they are room temperature when you put them in, pull them at 7 minutes or they will overcook and the centers will set. If you use a larger container and a larger amount of batter in your baking dish, you will have to adjust your cooking time.
Let them rest for 3 minutes before turning them out. Serve these warm but not hot.
