Here is a fabulous recipe my dear friend Betty shared with me several years ago. I make it when I need a coffee cake type dessert. I have never tried it with a different cake mix but if you cant find the Butter Pecan cake mix--Betty Crocker makes it--Im sure it would be good with yellow or spice cake mix.
Butter Pecan Cake
1 box Butter Pecan Cake Mix
3/4 c. oil
1 c. water
Mix above ingredients well. Add 1 can coconut pecan frosting to the batter.
Pour into a well greased and floured tube or bundt pan. Bake at 350 for 50-65 minutes until toothpick comes out clean.
