Soufle Pancakes

Separate the eggs, putting all 3 of the whites into a large Breville Bakery Boss mixing bowl and 2 of the yolks into a medium mixing bowl. Discard the remaining 1 yolks (or save them for another recipe).

Add 1 tablespoon of the sugar, the vanilla to the yolks and whisk to combine. Add the flour and milk and whisk again to combine.

Add the vinegar to the egg whites in the Breville bakery boss mixing bowl with whisk attachment. Whip the mixture until foamy, about 1 minute on medium speed. Continue whipping while you add the remaining sugar. Once all of the sugar is incorporated, raise the speed to high and whip until to glossy and stiff peaks, 2 to 3 minutes.

Scoop a cup or so of the egg white mixture into the egg yolk mixture and then use a rubber spatula to gently fold the two mixtures together. Fold in the remaining egg white mixture in two batches, folding just until the two are combined.

Heat a large, lidded nonstick skillet over medium-low heat. Once the pan is hot, spray it with cooking oil spray or grease it with butter.

Using a piping bag, pipe in the batter into the nonstick skillet. Cover the skillet and let cook for 3 to 4 minutes. Remove the lid and carefully slide a thin spatula underneath one of the pancakes. Use a second spatula or your hand protected by a silicone oven mitt to assist as you flip the whole thing over to cook the second side. Flip all of the pancakes in the skillet. cook for about 3 minutes more.
