Step 1

Preheat air fryer to 370 degrees F (185 degrees C). Spray a silicone egg-bite mold with nonstick cooking spray.

Step 2

Whisk flour, sugar, water, egg yolk, butter, baking powder, vanilla extract, and salt together in a large bowl. Stir to combine.

Step 3

Beat egg white in a small bowl using an electric hand mixer on medium speed until soft peaks form. Fold into batter. Add batter to the prepared mold using a small hinged ice cream scoop.

Step 4

Place filled silicone mold into the basket of the air fryer.

Step 5

Fry in the preheated air fryer for 10 minutes. Remove mold from the basket carefully; pop beignets out and flip over onto a parchment paper round.

Step 6

Place parchment round with beignets back into the air fryer basket. Cook for an additional 4 minutes. Remove beignets from the air fryer basket and dust with confectioners' sugar.
