In a large mixing bowl, combine graham crumbs, melted butter and 1/4 cup sugar. Press into the bottom of 13x9-inch baking pan. Stick in the fridge while you prepare the cheesecake mixture to let it firm up.
In another mixing bowl, beat softened cream cheese and remaining 3/4 cup sugar until completely blended. Add in dry Jell-o mix; mix well. Gently fold in Cool Whip and peaches. Pull pan out of fridge and pour cream cheese mixture over crust. Spread evenly using a spatula.
Place pan back in the fridge and refrigerate for about 4 hours or until firm.
Notes
