One of my extended family's favorites, too! We call it "Sex in a Bowl". I use pecans in the crust, and have made it with the pudding and whipped cream topping. But, instead, our favorite is canned pie filling. Strawberry is the best, and cherry comes in a close second. YummmmYummmmm......
All the kinfolks are disappointed if this dessert doesn't show up at family gatherings and meals.
