Increasing ingrediants for a cake
REbecca
02/09/06 		Hello, this is a great site (I'm in the UK). I'm baking a cake for a party, it's called American-style Raspberry Cake, it serves 8-10 people in a 9inch cake tin. I want to increase this to serve 45 - 50 people. I'm wary of just increasing all the quantities equally, can you help please? Here are the original quantities:-

Ingredients
For the crumble topping:
45g plain flour
45g Walnuts, finely chopped
1-2 tsp ground cinnamon
pinch of Salt
45g unsalted butter, melted
125g raspberries (or diced plums if preferred)
60g light muscovado sugar, light muscovado sugar

For the cake:
150g self-raising flour
1 tsp Baking powder
pinch of Salt
150g soured cream or thick Greek yoghurt
1/2 tsp vanilla extract
45g unsalted butter, melted
110g caster sugar
1 large egg

Thank you Rebecca
