Preheat the oven to 350 degrees. Spray a 9 x 13 pan with cooking spray and set aside.

In a large bowl, whisk together the flour, sugar and salt.

Cut in the butter using a pastry cutter until you have a crumbly mixture.

Remove about 1 ½ c to save for the top crust. Press the remaining dough into the bottom of the pan and press down into an even layer.

Place in the oven and bake for 13-15 minutes, until golden brown.

Remove and let cool.

To make the filling, whisk the eggs in a large bowl.

Add in the sour cream, nutmeg, cinnamon, salt, vanilla and flour.

Whisk until smooth.

Use a spatula and fold in the diced peaches. Pour the filling over the crust and smooth into an even layer.

Take the remaining crust and sprinkle over the top of the peach mixture.

Place the pan back into the oven and bake for 55-60 minutes, until golden brown. Remove and allow to cool.

To make the glaze, place the powdered sugar, 1 tablespoon of cream and the vanilla into a medium sized bowl and whisk.

Continue to add heavy cream until you get the consistency desired.

Drizzle over the top of the bars.

Slice and serve!
