Place cream cheese and 3 tablespoons sugar in a medium bowl; beat with a mixer at high speed for 2 minutes or until smooth. Beat in yogurt until blended.
Combine 1 tablespoon sugar, peaches, and raspberries in a large bowl, tossing to coat. Let stand 5 minutes.
Spoon 2 tablespoons cheese mixture into each of 6 (8-ounce) glasses; top each with 1/4 cup peach mixture and 2 1/2 tablespoons cookie crumbs. Repeat layers once with remaining cheese mixture and remaining peach mixture; top each with 2 whole cookies. Cover and chill until ready to serve.
