Step 1

Preheat oven to 375.

Step 2

Combine flour, 1 cup of sugar, baking powder, and salt in a medium bowl. Add butter to flour mixture and toss. Using a fork or pastry cutter, blend in the butter to create a crumbly texture. Whisk the egg slightly, and stir it into the mixture. Press half of the dough into a greased 9x13 baking pan.

Step 3

In a separate bowl, stir together your remaining ½ cup sugar and your cornstarch. Add the sliced peaches and gently mix. Spoon peaches over the pressed crust. Crumble your remaining dough over the peach mixture.

Step 4

Bake at 375 for 45-55 minutes. Top should be slightly brown.

Step 5
