In the bowl of a stand mixer, combine egg, egg yolks, water, yeast, canola oil, sugar and salt. With the dough hook on low speed, slowly add the flour. Mix for about 8 to 9 minutes or until dough comes together. If the dough seems sticky, add a bit of flour.
Shape dough into a ball on a lightly floured surface. Grease a large bowl with canola oil and place dough in the bowl. Cover with plastic wrap and let rest in a warm place for about 1 1/2 hours to 2 hours or until doubled in size. You may put the dough in the fridge overnight or shape and cook the same day.
Once the dough is shaped, put into a lightly greased loaf pan or on a lightly greased baking pan if doing individual mini buns. Let rise in a warm place for about 90 minutes, covered with a kitchen cloth or lightly wrapped with plastic.
Once the dough has risen to about the top of the loaf pan, cook in a 350˚F (175°C) oven for about 25 minutes or until golden and cooked through.
Wait 30 minutes to slice.
