Tiramisu tart

The return of this Buyer's pie circle that I love so much! This time I used it to make a tiramisu tart; this idea had been on my list of recipes to bake for a very long time, but I love classic tiramisu so much that I was afraid of being disappointed by changing the recipe and adding elements to make a tart. As you can imagine, I'm posting the recipe here, no disappointment at all, but a delicious pie with the basic elements of tiramisu, coffee, mascarpone and chocolate. I reused the recipe of Karim Bourgi's mascarpone cream, it is perfect and allows to keep the tart longer since the eggs are cooked, contrary to classic recipes.
