I have a very good cake that I bake in my bundt pan, but I don't think it has the filling you are looking for. I'm guessing that the kind you want would be cake with like a cream or jelly type filling that would look like a ring trough the cake? I think I remember seeing some like that in one of my Taste Of Home mags. I did find this one on their site:
Pear-Filled Bundt Cake Recipe | Taste of Home Recipes
It looks good, but it has a fruit filling. My bundt cake has fruit, but it is blended in before I bake it. It started out as the 'Aloha Cake' and I tweaked it so it's my 'Mandarin Orange Spice Cake' Let me know if the link helped

And if you want my recipe
Peace
