The recipe I heard was to mix cake mis with bisquick and follow the directions for biscuits on the bisquick box.
But I am sure I wouldn't like tha artificial flavors in the cake mix. If you want sweeter shortcake, just add a little more sugar and a teaspoonful of REAL vanilla extract.

I know a genuine, old time strawberry short cake is supposed to be made with a biscuit dough, but I never liked it made that way. I always make a sponge cake. Much tastier that way, and much more like the dessert it is supposed to be!
