Thanks so much for comments!
The person the cake was for is from Mexico. She talked about wanting a filling like her aunt used to make which was pineapple with coconut added but no corn starch or flour. She didn’t have any more info than pineapple, sugar and cinnamon and cook (and add coconut). I kept searching on the web for recipe. I winged it the first time. This time when I looked again, I found essentially what I did on my wing which was summarized as Latin pineapple marmalade. Much less syrupy and more loose than pineapple fillings on cake. I also cooked it a long time but it is tasty!
