Ice cream is a great fast dessert! Dress it up! Crush cookies (Lorna Doone, chocolate chip, macaroons, Oreo's, etc) and layer in parfait glasses with ice cream and fresh fruit. Top with cool whip or whipped cream.
You can do the same thing with instant pudding.
Make a quickie using instant pudding and graham cracker or cookie crust for an instant pie. Use banana cream pudding with sliced bananas lining the crust. Stir in chocolate chips for vanilla or chocolate pudding. Add drained fruit cocktail to pistachio pudding. Garnish to "fancy up" with chopped nuts, whipped cream, cool whip, etc.
No time to bake - use a frozen pound cake (or make several and freeze for future use). Thaw, cut into cubes, layer with fruit, pudding, whipped cream or cool whip to make trifle.
Slice an angel food cake in half or thirds horizontally and fill each layer with fruit, canned pineapple, pudding, whipped cream, etc.
These are desserts that can be made in minutes and enjoyed.
