Thinly slice peaches and toss with lemon juice in a bowl, set aside.
In another bowl cream butter and 1 cup sugar until fluffy. Add eggs and vanilla and beat well with electric mixer.
Sift flour, salt and baking powder and add to mixture. Put into well greased 8 in spring-form pan.
Place peaches on top and sprinkle with vanilla sugar or, if you can get your hands on it, the wonderfully named Gluttony butterscotch and sugar grinder.
