Preheat oven to 375°. Grease a 9×13 inch pan, set aside.

In a large bowl, whisk together sugar, flour salt and baking powder. Using your hands, fork or pastry cutter, cut in the butter until it resembles a coarse meal. (I like to use my hands.) Mix in the egg until fully combined. Press half of dough into the prepared baking pan and bake for 7 minutes.

While the crust is baking, gently stir together the peaches and lemon juice. In another bowl, whisk together the flour, sugar, salt and spices. Stir both mixtures together very gently until peaches are fully coated. Once crust is done, spread peach mixture over the warm crust and crumble the remaining dough over the filling. No need to make this absolutely perfect, it's looks nice when some peaches show through. Place back into oven and bake for another 35-45 minutes or until top starts to turn slightly golden. Once done, allow them to cool for 20 minutes before cutting.

Bars will stay fresh for up to 5 days stored in an airtight container at room temperature or up to 7 days stored in the fridge. They will get soft after day 1, but this doesn't affect the flavor at all.
