In a food processor pulse the rolled oats 4-5 times, just until they start to break up. Remove about two-thirds of the oats (3 ⅓ cups, but no need to be exact) and pulse the remaining oats to a fine powder.
Combine the oats, sugar, powdered milk, salt and any optional additions. Store in a large airtight container or portion out into individual servings and store in zipped bags. Mix should keep for 1-2 months.
