This no-bake recipe creates a decadent Nutella tart featuring a crunchy crust made from Nutter Butter cookies. The process involves crushing cookies and combining them with melted butter for the base, then preparing a rich Nutella filling with whipped heavy cream and egg yolk. The tart is then chilled until firm, resulting in a luscious, easy-to-make dessert.
For a truly stable crust, ensure your Nutter Butter cookies are pulverized to a fine crumb; any large pieces will compromise its integrity. Press the crust firmly and evenly into the tart pan, paying special attention to the sides. When preparing the filling, whip your heavy cream to soft peaks before gently folding it into the Nutella and egg yolk mixture. Overmixing can deflate the cream, leading to a less airy, dense filling. The egg yolk adds richness and helps stabilize the emulsion, providing a smoother, more luxurious texture. Thorough chilling is crucial for the tart to set properly; aim for at least 4-6 hours, or ideally overnight. Garnish with a sprinkle of flaky sea salt or a few toasted hazelnuts to cut through the sweetness and add textural contrast.
