Today I am presenting a peach tart with only four ingredients: peaches, flour, sugar, and butter. If you have these ingredients at home, feel free to get started on this beauty. This is an upsidedown cake, so you will need an ovenproof pan. However, the tarts I photographed here were all made in Spain and I didn’t have an ovenproof frying pan. This is also possible, just make the caramel separately. Think caramelized peaches that are held together by some dough and you will get this summery dessert. Serve with a dollop of whipping cream or ice cream and you’ve got summer on your plate.
