Used Gluten- Free Pantry decadent chocolate cake mix to make my birthday cake. And coconut/ pecan frosting--- works for a german choc cake for me!
I wanted a 2- layer cake (love the frosting between the layers), but it's just me & DH here, didn't want a whole ton of left- over cake. So just baked one layer in a round cake pan, let it cool, cut it in half, frosted the bottom half, then put the top on & frosted it . It may not have been super perfect, but I liked how it turned out!
And from what I've tasted of the cake (waiting till desert time for my big piece of the day. and of course, i will have ice cream, too!) it was yummy... would never have been able to tell it is gluten-free!!
On the back of the box is also a recipe for cupcakes (using the mix, of course) I think it would be a good idea to make up a batch of those & have in the freezer to grab to take to picnics, ect.
