Heat oven to 350 degrees. Generously grease and flour 2 round pans, 8-or 9-x1-1/2-inches. Drain peaches, reserving sauce. Add enough water to reserved sauce to measure 1-1/4 cups.
Prepare cake mix as directed on package, except substitute sauce mixture for the water.
Pour batter into prepared pans. Bake and cool as directed. Cut peaches into bite-sized pieces.
Mix yogurt and whipped topping; fold in peaches. Fill middle layer with about half of the peach mixture and place second cake on top. Spoon remaining peach mixture over top of cake.
Refrigerate about 2 hours or until chilled.
