"This is a homemade roll recipe from my sister's mother-in-law. I make these for every holiday or special meal and my family wouldn't have it any other way! They are the best served with the honey butter."
Stir boiling water and oats together in a bowl; set aside to thicken and cool, 10 to 15 minutes. Stir brown sugar and vegetable oil into oat mixture.
Dissolve yeast in lukewarm water in a bowl. Let stand until the yeast softens and begins to form a creamy foam, about 5 minutes. Stir yeast mixture and salt into oat mixture. Beat flour, 1 cup at a time, into oat mixture until dough is soft. Turn dough onto a floured surface and knead for 10 minutes.
Place dough in an oiled bowl and cover with a damp towel; let rise until doubled in size, about 1 hour.
Punch dough down and form into rolls; arrange on baking sheets. Let rise again until doubled in size, about 30 minutes.
Preheat oven to 350 degrees F (175 degrees C).
Bake rolls in the preheated oven until lightly browned, 20 to 25 minutes.
Beat butter, honey, and cinnamon together in a bowl using an electric mixer until creamy and smooth. Serve honey butter with rolls.
