Birthday cake blog

You already know the recipe , so let's be specific about the baking of this particular cake.
I arrived home last night, confident that I had all the ingredients for Granny Grene Chocolate Cake, which I needed to prepare for this morning. My plan was clear and achievable: make the cake, put it in the oven, spend 20-25 minutes pottering over some chores, take the cake out of the oven and go to bed well before midnight. This would have made it easy to get up early, ice the cake and deliver it before going to work.
This all went swimmingly until it came time to measure out the flour and cocoa . I knew for a fact that I owned (in the sense of paid for and have not yet used) 1 1/2 small pots of Green & Black's Cocoa , and a large pot of supermarket own brand cocoa. Unfortunately I had not bothered to pack them in the last move, so they are all sitting in a kitchen cupboard in Chelsea, an hour's bike ride away.
NO COCOA!
Not a disaster. Put jeans on instead of pyjama bottoms, hop on bike, up to late night shop. Nearest LNS closed; go to the next one. Next two also closed. Head down Green Lanes (a lively or dangerous road, depending on your sense of adventure) to the 24-hour convenience store. First one: no cocoa. Second one: five different varieties of drinking chocolate, still no cocoa.
Back on the bike to get to another shop - this one I'm confident will provide.
But the nice police constable politely asks me to wait while the police photograph the crime scene between me and the final shop. Finally traffic is allowed through and I gingerly cycle past, not liking to stop and peer at what I think are bloodsoaked rags behind the police incident tape.
The last shop has cocoa!
Invigorated by my success, I zoom home to complete the interrupted baking.
After this adventure, it scarcely seems worth commenting on the actual baking, icing, decorating and eating of the cake. I would just like to say that my fan oven, which up till now I have found unsatisfactory, seems to bake cake beautifully.
Happy birthday, Jack!
