Remove dough from refrigerator and place on a lightly floured cutting board. Combine butter and powdered sugar. Add honey and vanilla and mix until smooth. Set aside.
Combine cinnamon and sugar and set aside.
Cut each loaf into 16 slices. Spoon butter mixture over slices and sprinkle with cinnamon sugar.
Place the slices of each loaf into a loaf pan that has been lightly sprayed with nonstick spray. Sprinkle with any remaining cinnamon sugar.
Place loaves in a warm place and let rise until doubled, about 1 hour. Preheat oven to 350 degrees. Bake loaves for 25 minutes - the tops will be golden brown. Remove pans from oven and carefully cover both loaves with aluminum foil. Return them to the oven to cook for 15 more minutes for a total cook time of 40 minutes.
Remove from oven, remove foil, and let cool.
Combine ingredients for glaze and drizzle over cooled loaves.
