Pear and walnut cake (1 colour)

I made this with freshly bought pears, but next time I shall leave them to ripen for a day or two.

Ingredients
Plain flour - 250 g
Caster sugar - 180 g
Baking powder - 2 tsp
Pears - 3 ripened, peeled and coarsely chopped
Walnut pieces - 80 g
Eggs - 2, beaten
Milk - 100 ml
Butter - 125 g

Methods
1) Melt the butter in a pan and leave to cool. Preheat the oven to 180 °C and grease a 9 inch round baking tin.
2) Sift the flour, sugar and baking powder into a large mixing bowl. Add the pear and walnut pieces and mix well.
3) Place the milk and eggs together in a small bowl and whisk for a couple of minutes.
4) Add the milk and egg mixture together with the butter to the mixing bowl. Mix thoroughly.
5) Pour into the baking tin and cook for 45 minutes or until a skewer comes out clean. Serves 6-8.
