What if I only have regular old-fashioned rolled oats and not the quick-cooking? You can make your own “quick” oats by pulsing regular rolled oats in the food processor to break them down. Add a 1 ¼ cups of oats to the food processor then pulse until the oats are chopped but some larger pieces still remain (they should not be a fine powder). Once the oats are chopped, measure the amount needed in the recipe.
