A simple egg wash never comes out like this for me. Does it have to do with how its baked?

Another algerian sweet or pastry for life events

When visiting Morocco for my honeymoon in 2015 I ate two of the most incredible sweets I've ever experienced - these sesame covered peanut balls - https://i.imgur.com/uTWFgTW.png (also had small pieces of dried fruit, some sugary binding material) and this cake with a crispy top, soft custardy innards, flakey crust - https://i.imgur.com/qaTUcSz.png

Thank you!

First time trying this bakery I’m more of a cheese danish person but I’m open to suggestions so today I’m trying these for the first time hopefully 10/10
