This cake was for my Dad's birthday. I found it on Annie's Eats - another Annie who made it for her Dad's birthday! Sounds perfect! I am not a big fan of coconut, so I omitted it and added extra nuts instead. So it was really nutty, but very good! I used my food processor to chop the recommended amount of nuts with an extra half of a cup instead of the coconut.
Annie from Annie's Eats also recommended using less rum syrup, so I followed her recipe changes and still had extra syrup.
There's a really nice printable version of the recipe on Annie's Eats... you can check it out there!
