Directions

1. Warm the milk in a small saucepan until it bubbles, then remove from heat. Mix in the 4 tablespoons butter; stir until melted. Let cool until lukewarm.
2. Pour milk mixture into bread machine pan. Add 2 eggs, 1/2 cup sugar, vanilla extract, 4 cups bread flour, yeast and salt. Choose Dough setting; press start.
3. When dough is finished mixing, leave it in the bread machine pan and cover with a towel. Let rise until doubled, about 45 minutes.
4. Deflate the dough and turn it out onto a lightly floured surface. Divide the dough into two equal pieces and form into loaves. Place the loaves into two lightly greased 9x5 inch loaf pans. Cover the loaves with a damp cloth and let rise until doubled in volume, about 40 minutes. Meanwhile, preheat oven to 350 degrees F (175 degrees C).
5. In a small bowl, combine 1/4 cup sugar, 1/4 brown sugar and 1/3 cup flour. Cut in butter until mixture resembles coarse crumbs; set aside. In a separate bowl, beat together 1 egg and 1 tablespoon water.
6. Brush loaves of risen bread with the egg wash and then sprinkle on crumb topping. Bake at 350 degrees for about 30 minutes, until golden brown.
