Frozen peach Shortcake Squares

We hosted some friends for dinner last night, and recipes were requested. Here's the menu: Apricot stuffed chicken breasts, roasted asparagus, herbed roasted potatoes, and smokey bacon onions. Dessert was as follows...

Frozen Peach Shortcake Squares
2 cups thawed Cool Whip Whipped Topping
2 cups Vanilla ice cream, softened (I used Nestle "Real Dairy" ice cream)
1 pkg. (85 g) Peach Jelly Powder
4 cups Prepared pound cake cubes (1 inch cubes)
1/4 cup Kraft Pure Red Raspberry Jam, warmed (I used the seedless variety)
2 small fresh peaches, each cut into 6 slices
12 fresh raspberries
fresh mint-optional

MIX first 3 ingredients in large bowl until well blended. Stir in cake cubes. Spoon into 8-inch square pan.

FREEZE 3 hours or until firm.

DRIZZLE with jam. Cut into squares; top each with 1 peach slice and raspberry. Garnish with mint if desired.
