This is a great recipe for feeding a crowd, and the presentation is beautiful.

could i make this cake using a DIFFERENT cake mix?

I am all about chocolate, however, you could easily switch out the chocolate cake mix for a vanilla or white.

We highly recommend giving either flavor a try because chocolate and white cake, are both delicious with this recipe.

what other frosting could i use with this cake recipe?

My family and I are the biggest frosting fans. We all love our frosting portion to be equivalent with our cake portion.

This recipe has a peanut butter buttercream frosting to it, but you could easily switch it up, and use a different frosting flavor.

Here are a few of our other favorite frostings to make this recipe with:
