Next, I mix everything together until the crumbs and Nutella combine into a thick, moldable paste. The mixture should feel similar to cookie dough—soft but able to hold its shape when pressed. If it feels too dry, I sometimes add just a small extra spoon of Nutella to help it come together.
To assemble the centers, I take a small amount of the wafer mixture and flatten it in my palm. Then I place a tiny drop of Nutella and one whole toasted hazelnut right in the center. I carefully fold the mixture around the hazelnut and roll it between my palms until it forms a smooth ball.
Once all the balls are formed, I place them on a tray lined with parchment paper and transfer them to the fridge for about 30 minutes. I’ve learned that this chilling step is really important because it helps the truffles hold their shape when they’re dipped into the melted chocolate later.
Pro Tips for Best Results
After making these several times, I’ve realized that finely crushed wafers work best for the base. If the crumbs are too chunky, the balls can crack when rolling them. A smooth crumb texture helps everything stick together more easily.
Another tip I’ve learned is to make sure the hazelnuts are toasted before using them. Toasting brings out their natural oils and gives them that deep nutty flavor that makes Ferrero Rocher so special.
I also like chilling the balls long enough before dipping them in chocolate. I once skipped this step because I was in a hurry, and the truffles started falling apart in the warm chocolate.
Common Mistakes to Avoid
The first mistake I made with this recipe was adding too much Nutella to the wafer crumbs. While Nutella tastes amazing, too much can make the mixture too soft to shape properly.
Another mistake is skipping the chilling step before dipping. When the centers aren’t cold enough, they soften quickly in the melted chocolate and lose their round shape. (See the next page below to continue…)
