Whip the cream.
Pour the cold heavy cream into a bowl. Add powdered sugar and vanilla, then whip until soft peaks form. Stop before it turns stiff—this cake likes soft and fluffy, not butter vibes.
Mix in the Nutella.
Gently fold Nutella into the whipped cream. Don’t overmix. You want a smooth, light chocolate-hazelnut cream, not a sad deflated mess.
Prep the Oreos.
Quickly dip each Oreo into milk. One second per side is plenty. If you soak them, they’ll fall apart and ruin the vibe.
Start layering.
Line the bottom of your dish with dipped Oreos. Spread a thick layer of Nutella cream on top. Repeat the layers until you run out, finishing with cream on top.
Chill like a pro.
Cover and refrigerate for at least 6 hours, but overnight is even better. This is where the magic happens—the cookies soften and turn cake-like.
Final touch.
Before serving, add crushed Oreos or a drizzle of Nutella on top if you’re feeling fancy (and you should).
