Add the espresso to your bowl with milk and mix well. Heat it for 30 seconds in the microwave, so it's warm but not piping hot.
Chop your pistachios with a knife.
Choose your casserole. If you prefer, you can also make two portions into large dessert glasses. That's how I usually make my healthy tiramisu portions.
If you want, you can sweeten your mascarpone with some white table sugar. I didn't.
Gather all the rest of the ingredients and you are ready to assemble the tiramisu.
Start dipping the first layer of lady fingers into the coffee milk. Layer them on the bottom of the casserole.
Spread one tablespoon of Belmorso Pistachio spread on top of the lady fingers, or you can drizzle it instead.
Top with half the mascarpone.
Repeat one more layer of dipped lady fingers, pistachio spread, and mascarpone.
Finish with the final layer of dipped lady fingers.
Top with more pistachio spread drizzle.
Add the chopped pistachios.
Add the powdered cocoa or grated dark chocolate; you can also add drizzled or melted chocolate of your choice.
Refrigerate for at least 2 hours before enjoying.
