Soften yeast in the 1/3 cup warm water.
Add vanilla extract and egg to milk mixture. Add softened yeast. Add flour gradually
as needed. Knead dough on floured surface until smooth. Let rise until double.
Punch dough down and divide in half. Roll each half to a 12 x 15-inch rectangle.

spreading as evenly as possible. Roll up and pinch edges to seal. Place in greased
bread pans and let rise until double for 30 to 35 minutes.
