FOOD PRODUCTS
In general, foods that are cooked, canned, frozen or commercially processed and/or packaged are allowed to be transported to Hawaii, as long as the product is arriving from within the U.S.
Frozen or chilled meats are also allowed to be transported to Hawaii as long as the meat originated from within the U.S.
Manufactured food products are not required to be declared or inspected.
My advice would be to bring the packaged ingredients in your luggage and make up the trail mix when you get there.
If you need some during the flight I'd only take along enough mixed trail mix for the flight itself in case you are asked to dump it at the airport.
Internationally
If you are arriving from another country, then it becomes a US CBP issue and the relevant link is: Travelers bringing food into the U.S. for personal use. That site explicitly lists a large number of allowed/disallowed products. So check off your ingredients to see what is/isn't allowed.
