Grab the largest mixing bowl you have to comfortably hold about 9–10 cups of trail mix and allow room for stirring.
Add the roasted salted peanuts, roasted almonds, cashews, and sunflower seeds to the bowl. Gently toss with clean hands or a large spoon until evenly combined.
1 1/2 cups roasted salted peanuts, 1 1/2 cups roasted almonds, 1 cup cashews, 1/2 cup sunflower seeds
Add the raisins and dried cranberries. Break apart any clumps with your fingers so the fruit is evenly distributed.
1 cup raisins, 1 cup dried cranberries
Add the mini pretzels or pretzel sticks. If the pieces are large, lightly crush them first so they’re bite-sized. Gently toss to combine.
1 cup mini pretzels or pretzel sticks
Pour in the plain M&Ms and peanut (or other flavored) M&Ms. Stir gently so the colorful candy is scattered evenly throughout the mix.
1 1/2 cups plain M&Ms, 1/2 cup peanut M&Ms
Scoop a small handful and taste. If it’s too salty, add more dried fruit. If it’s too sweet, add more nuts or pretzels. If you want more chocolate, add extra M&Ms to taste.
If using shredded coconut, sprinkle it over the top and give the mix one last gentle toss, breaking up any coconut clumps.
1/4 cup shredded coconut
Transfer the trail mix to airtight containers, jars, or small snack bags for easy grab-and-go portions. Store at room temperature, in the fridge, or freezer as desired.
