Hello @anggreklestari. It's been a while since I was in the kitchen baking. I had enough energy to try this dessert. Already ate one of the cups. I think I may switch permanently to Ginger Snaps from vanilla wafers that used for many years.
You can also substitute the wafers for any you like as the crumb portion. I never thought of mango. To me that would completely change the taste, but I'll have to give it a sample.
Thanks so much for your visit and view of my recipe and dessert. I appreciate it. Take care.
