Sorry your cake pleas have been ignored Herbs!
The classic birthday cake here every time is this easy peasy can't go wrong one:
Weigh 4 eggs.
Beat same weight (as eggs) of butter and same weight again (as eggs) of caster sugar together.
Beat in eggs one by one, after 3rd one sift in some of the self raising flour you have already weighed out - same weight as - you guessed it, the eggs, but replacing 50g of it with cocoa powder with the last egg.
Add vanilla essence to taste.
Fold in the rest of the flour/ cocoa.
Add around 2 tablespoons milk or enough to make consistency one where will drip from an upturned spoon.
Divide between 2 greased, lined sandwich tins (7"? 10"?) and bake in oven at 180c for around 25 mins. Turn out to cool.
Sandwich together with jam / raspberries / cream or chocolatey fudgy icing as you prefer.
Ta Da!
Fingers crossed for the weather. If raining I think you have to embrace that like you say. Ds2 once had a "tree climbing" birthday party on Hampstead Heath (his choice) in the POURING rain and it was great - if v damp. One mother wouldn't let little Tarquin attend as she was worried he might be struck by lightning.
Off to Sheffield tomorrow on the last leg of the Uni tour. Wish me strength.
Well done to all the proud parents with glowing school reports in their possession! Oh and their children....
