Maybe amarula, bourbon cake??? Maybe those with a nut??? Walnut???
Or amarula, bourbon and pudding???
Or perhaps amarula, bourbon ice cream.
Amarula and a cake, for sure, I think would work well together. I struggle to identify a fruit that might go best with amarula. From my sft notes, I did get an almost pear like note in the amarula. Based on that I am thinking a pear would work well.
Maybe starfruit. Shortbread cookie.

Fran, don't read the "sweet" part in that link. Says chocolates, custards, cheesecakes with a cookie crust (or graham I'd imagine) go with Amarula.
This link also has some good ideas.
