Bake at 350 °F for 15–18 minutes or until wooden pick inserted in center comes out clean.
Cool on wire rack 10 minutes.
Remove from pans and cool completely.
Frosting
Combine cream cheese and butter in large mixer bowl; mix at medium speed until well combined.
Add vanilla; mix well.
Add powdered sugar a little at the time, mixing until mixture is of spreading consistency.
Spread between layers and on top of chocolate pecan coconut cake.
Sprinkle with chopped pecans, if desired.
Notes
For testing purposes, Duncan Hines German Chocolate Cake Mix was used. The taste and texture of the cake and frosting were good despite the fact that the recipe was made from a cake mix base.
