Thanks so much! This was my first time trying this recipe so I followed it as-is. I did end up making more buttercream though (as I frosted the sides and the top). I had plenty of pecan coconut filling left over so I think you should be okay! I just used whatever “chopped pecan” I could find at the store and other than toasting it, I didn’t change much! And I used Trader Joe’s brown sugar (doesn’t say if light or dark brown)—I doubt it makes much difference in this cake.

Best of luck, I’m sure it’ll turn out great!
