In a medium bowl, soak the oats in ½-cup of milk for 10 minutes.

In a large bowl, whisk together the flour, baking powder, baking soda, and salt.

Add the lightly-beaten egg, brown sugar, vanilla extract, yogurt, remaining ¼-cup of milk, zest, berries, and soaked oats to the dry ingredients. Stir until just combined.

Heat a large skillet or non-stick griddle over a med-high flame and brush with butter. Once piping hot, reduce the flame to medium and parcel out batter by the tablespoon-full (aim for a diameter of about 2½-3 inches) Cook each pancake for about 2 minutes or until golden, then flip and cook the other side. To make sure the outside doesn’t burn, you may need to turn heat down to medium-low. Repeat until all batter is cooked.
