Preheat your air fryer to 330°F (165°C) for about 5 minutes.

Open the tube of Pillsbury Grand Biscuits and separate them into two thinner layers. Flatten each into a circle about 4 inches in diameter.

Place 1 tablespoon of Nutella in the center of each flattened biscuit, being careful not to overfill.

Fold the edges of each biscuit over the Nutella filling and pinch the seams to seal.

Brush the melted unsalted butter over the exterior of each Nutella bomb.

Carefully place the Nutella bombs in the air fryer basket, leaving space for air circulation.

Set the timer for 7-8 minutes and air fry until golden brown.

Once cooked, let them cool for 3-5 minutes and dust with confectioners' sugar before serving.
