Gluten Free Pear Cake

I was cooking and baking for a few coeliacs last week. This cake was a little thrown together from some left over pears from a pud a night before and I made the recipe up based on a sponge but it was very good actually, especially eaten warm out the oven. 

225g caster sugar

175g of rice flour

1 heaped tbsp corn flour

50g ground almonds

4 eggs

poached pears cut into pieces  (in sweet wine, citrus peel and brown sugar)
225g unsalted butter

1tsp baking powder (gf)
