(The jellies require approximately 2.5 hours to prepare and set.) Jelly Nutella Expresso is a dessert served in a trapezoid-shaped glass, featuring a square block of firm Nutella-flavored jelly with a hint of expresso. This treat combines the rich, creamy taste of Nutella with the bold flavor of expresso in a smooth, slightly chewy texture. You can also add whipped cream or other toppings from the menu to customize and elevate the indulgence.
