Combine the butter, yeast, sugar, salt and 1 cup warm water in a stand mixer fitted with the dough hook attachment. With the mixer on low speed, add 1/2 cup of the flour at a time, waiting for each addition to be fully incorporated before adding more. Once all of the flour is added, knead on medium speed for 8 minutes.
Transfer the dough to the prepared pan, cover and let rise until doubled in size, about 1 hour.
Add the pan with the dough to a 3.5-quart air fryer and set to 380 degrees F. Cook until the bread is dark brown and the internal temperature registers 200 degrees F, about 20 minutes. Let cool in the pan 5 minutes, then turn out onto a rack to cool completely.
When measuring flour, we spoon it into a dry measuring cup and level off excess. (Scooping directly from the bag compacts the flour, resulting in dry baked goods.)
