4. Mix until yeast is dissolved, then let mixture stand for about 5 minutes until yeast has developed.
5. Add milk, vanilla, eggs, flour, and salt.

7. Add butter, a couple pieces at a time, letting them combine into the dough.
8. Add the remaining sugar and mix for another 4 minutes. Check the dough: if you can stretch it out for about 3 inches without it breaking, it's ready. If it tears, mix a couple more minutes.
9. Transfer dough to lightly floured board and form into a ball.
10. Place into prepared bowl, cover with plastic wrap, and let proof for about 2 1/2 to 3 hours until it has doubled in size. You can now use the dough, or refrigerate overnight and bring back to room temperature to use.For the apples:Peel, core, and cut apples in 1/2 inch cubes. Melt butter in a sauté pan over medium heat.
