Apple and almond cake bars

Gluten-free and rather yummy.

Ingredients:

4 oz real butter (salted)
3 oz sugar
4 oz ground almonds
3 eggs

1 large cooking apple
1 oz sugar

Method:
Preheat oven to moderate. Grease a square or rectangular non-stick baking tin.

1. Cream the butter with the 3 ozs of sugar.
2. Stir in the ground almonds.
3. Break the eggs into the mixture and beat them in.
4. Peel and core the apple and slice it into a saucepan. Add the 1 oz of sugar.
5. Put the pan on the heat and stew the apple until it is fluffy. Beat it to ensure it is all smooth.
6. Take the stewed apple and (while still hot) pour it into the almond mixture. Stir it quickly into the mixture and beat it a bit to add some air.
7. Pour the mixture into the greased tin.
8. Bake in moderate oven for about 25 minutes.
9. Cool in the tin and then cut into bars with a plastic spatula. Alternatively serve warm with custard for pudding.

For added interest add some lemon zest or pith, or cinnamon or ginger.
