For Memorial Day I bought a Pamela's Vanilla Cake Mix, baked it, cut it into cubes and layered it in a trifle bowl with sugared strawberries and whipped cream. I took it to a cookout with about 15 people present. It was gone in about 5 minutes with comments of 'so good, so good!" and my favorite "if this is gluten free, then obviously I don't need gluten in my life".
It was really yummy. I really think the vanilla flavor of the cake made it better than traditional shortcake.
