Layer fresh fruit, billowy whipped topping and melt-in-your-mouth shortbread cookies in see-through glasses to make these quick and easy desserts.
Cut 1-1/2 peaches into 1/2-inch pieces; reserve remaining half for snacking. Set aside 4 peach pieces and 4 raspberries for garnish. In a medium-size bowl, gently stir together remaining peach pieces, remaining raspberries, sugar and vanilla. Let stand 5 minutes.
In a large bowl, combine whipped topping mix and milk. Beat on low speed for 1 minute, then increase speed to high and beat 4 minutes, until fluffy and stiff (makes about 2 cups). Fold 1-1/2 cups of the whipped topping into yogurt in a small bowl (reserve remaining 1/2 cup topping).
Place about 1/4 cup fruit in the bottom of 4 glasses. Top each with 1/4 cup yogurt mixture. Crumble one cookie into each glass. Repeat layering, ending with cookies. Dollop reserved whipped topping over parfaits, about 2 tablespoons for each. Garnish with reserved fruit and mint, if desired.
