These tasty bars serve 16, but you're going to want more than one ;)
2 sticks unsalted butter, melted
2 cups all-purpose flour
1 cup oats
1 cups sugar
4 large peaches, peeled and chopped into small pieces
the juice of one lemon to squeeze over the peaches as you cut them to prevent browning.
¼ cup sugar
⅓ cup cornstarch
Preheat oven to 350 degrees.
Line an 8" x 8" or 9" x 9" square baking pan with foil.
Brush with a little of the melted butter
Stir together flour, oats and 1 cup sugar.
Pour remaining melted butter over flour mixture and cut in with a pastry cutter or a fork until mixture resembles coarse meal.
Press approximately half of the mixture into the bottom of the baking pan.
Stir together peaches, lemon juice, sugar, and cornstarch until all is moistened. Note: You should stir the lemon juice in to the peaches as you cut them to prevent browning.
Spread peaches evenly over the pressed in crust.
Sprinkle the remaining flour mixture over the peaches.
Bake for approximately 50 minutes or until top is golden brown.
