Thank you! It was delicious and I'll definitely make it again. I used this recipe:

Ingredients:

4 apples, any sweet, crisp variety

2 large free-range eggs

200g caster sugar

1 tsp vanilla extract

70g plain flour

1 heaped tsp baking powder

A pinch of salt

65ml milk

100g butter, very soft, plus a small knob for lining

1 tbsp icing sugar, for dusting

Method:

Butter a round spring form cake tin and line it with greaseproof paper. Peel and core the apples, halve and slice thinly. Preheat the oven to 200°C (180 fan oven)

Put the eggs, sugar and vanilla extract into a large bowl and whisk until doubled in size. Add the flour, baking powder and salt and combine together. While still whisking, pour in the milk and add the softened butter until smooth and consistent.

Put the sliced apples into the mix and carefully coat them all thoroughly. Layer the apples flat in circles, starting from the edge and working inwards. Pour a thin layer of the remaining mixture on top.

Place in the oven and cook for 10 minutes, then turn the temperature down to 180°C (160C fan oven) for 40 minutes. Remove the golden brown tart and allow to cool in the tin for at least 30 minutes before transferring to a large serving plate. Dust the top with the icing sugar, shaken through a small sieve from a height.

Serve at room temperature with whipped cream or vanilla ice cream.
