Next, mix the flours, baking powder, baking soda, and salt together in a medium-sized bowl until combined. Then in a separate bowl, whisk the yogurt, egg, oil, oats, and ¼ c. honey together until completely combined. After the yogurt mixture is combined, add in the milk. Then carefully mix the yogurt mixture into the flour mixture until it's just combined. If you mix too much, the bread will be really tough.
