Use day old croissants so I usually buy it a day ahead. Fresh croissants are soft so its not ideal.
Some recipes call for soaking the croissants in sugar syrup but I tried that and totally hate it because its too sweet ! Dislike!
So all you do is slice the croissants in half like how you would make a sandwich, set the oven to 180 degrees and make the filling
Filling Recipe:-
1/2 cup sugar
2/3 cup ground almonds
a pinch of salt
100g butter (softened)
2 eggs
Mix everything in until creamy and lastly add the eggs 1 by 1. Spread about 2 tablespoons in between the croissants. Cover and spread about 1 tablespoons over the croissants and sprinkle sliced almonds. Bake for 15-18 minutes until croissants are golden and firm. Dust with icing sugar and enjoy!!!
