In a stand mixer bowl with dough hook, combine the whole wheat flour and yeast.
In a separate bowl, combine the warm milk, butter, mashed potatoes, and sugar.
Add the milk mixture to the flour mixture and mix on low speed for 3-5 minutes.
Add half a cup of flour at a time and continue mixing until the dough forms and starts to leave the side of the bowl, about 3-5 more minutes. Don’t add too much flour though. The dough should still be sticky and soft, which will keep the buns soft.
Remove the dough hook and cover the bowl with Saran Wrap.
Allow to rest until doubled, 1-2 hours.
Using a little oil if desired, portion and shape your rolls: 3.1 ounce balls for 10-12 large buns, 2.5 ounce balls for 12-16 rolls For regular hamburger buns, and 1.5 ounce balls for 20-24 rolls for slider buns.
Place your rolls on a baking sheet and flatten slightly.
Sprinkle the tops with sesame seeds and cover with saran wrap.
Allow to rise 45-60 minutes.
Preheat the oven to 375° F.
Bake t5-18 minutes, depending on the size.
Remove from oven and cover with a clean towel, allow to cool for 15 minutes.
