- Prepare Nutella Ganache:
- Heat the heavy cream until it begins to simmer. You can do this on the stovetop over medium-high heat, whisking constantly, or in the microwave using short intervals (30-60 seconds at a time) until bubbles form around the edges.
- Add Nutella and butter, then whisk together until fully combined
- Allow to cool while you prepare the rest of the tiramisu
- Make the mascarpone cream:
a. In one bowl, whip together one 16oz container of mascarpone cheese, Nutella, and some of the heavy cream until smooth and creamy.
- In a separate bowl, mix together the other 16oz container of mascarpone
- Prepare the coffee: put brewed espresso in a shallow dish that will be easy for dunking
- Assemble the tiramisu: We used a 9x13 baking dish. Quickly dip ladyfingers in the coffee mixture and arrange them in a single layer in a dish. Spread a layer of the Nutella mascarpone cream over the ladyfingers. Repeat the layering process with the mascarpone mixture. End with some lady fingers on top.
5. Cover with Nutella Ganache: Evenly pour the Nutella ganache over the top of the tiramisu
- Refrigerate and serve: Chill the tiramisu in the refrigerator for at least a few hours, or ideally overnight, to allow the flavors to meld. Garnish with chopped, roasted hazelnuts before serving.
