OK anyway, so you will need -
200 grams white sugar
1 teaspoon baking powder
360 grams plain flour
1/2 teaspoon cinnamon
1/4 teaspoon freshly grated nutmeg
1/4 teaspoon salt
227 grams cold unsalted butter
1 large egg
2 peaches, pitted and thinly sliced (about 1/4-inch thick)
Brown your butter in a saucepan over medium-low heat until it smells nutty. Set it in the freezer until solid (about 30 minutes).
Preheat the oven to 190°C. Butter a pan. In a bowl, stir together sugar, baking powder, flour, salt and spices. Then blend the solidified brown butter and egg into the flour mixture. It will be crumbly. Pat 3/4 of the crumbs into the bottom of the prepared pan, pressing firmly. Tile peach slices over crumb base in a single layer. Scatter remaining crumbs over peaches and bake in preheated oven for 30 minutes, until top is slightly brown.
Cool completely in pan before cutting into squares.Voila!
Mine came out closely resembling a crumble (I think I packed the bottom layer too thick) but it was still pretty damn good (if I may so myself)!
