Mix all dry ingredients in a bowl, then add in all wet ingredients and mix with a spoon. Knead everything well or mix with a hand mixer.
Let the dough rest for 5 minutes.
Line a baking sheet with parchment paper. Use your hands to fashion a palm-sized ball of dough into a bun shape and place onto the paper. Repeat with remaining dough, spacing evenly on the sheet.
Sprinkle with seeds if desired.
Bake at 200 ° F (150 ° C) convection oven or 325 ° F (170 ° C) in an electric oven for 30 minutes.
