Start by placing an ovenproof baking dish on the oven and preheat it inside to 180 degrees.
Strain the peaches, reserving the peach juice. Cut the peaches into wedges.
Mix the flour, baking powder, 100 g sugar, vanilla sugar, milk, salt, egg, and lemon sugar in a bowl and whisk until smooth.
Put the butter in the preheated baking dish and melt it in the hot oven.
Then remove the casserole from the oven and, using a pastry brush, spread the batter in the baking dish. Brush the edges with it too.
Slowly pour the peach cobbler batter in a serpentine fashion into the baking dish on top of the butter. And do not mix them.
Spread the peach wedges on top of the batter.
Then sprinkle brown sugar and cinnamon and sprinkle on top.
Bake the Peach Cobbler in a preheated oven for about 45 minutes until crispy brown. The Peach Cobbler is not done until it rises as high in the center as it has around the edges.
Serve the hot Peach Cobbler with the peach juice or vanilla ice cream and whipped cream.
Have fun baking!
