Melt butter in a microwave safe measuring cup. In a separate measuring cup combine the Worcestershire sauce, onion, and garlic powder until it forms a thick paste.
Add a little butter at a time to the paste whisking vigorously until all the butter is added.
In a roasting pan combine the Shreddies, oatmeal 0’s, stick pretzels, and Cheese Nips.
Pour ¼ of the butter mixture over the dry mix gently stirring, repeat this process until the butter mixture is gone.
Bake in a 250°F oven for 1-1½ hours gently stirring every 15 minutes.
The mixture will darken in colour and should be dry. We always do a taste test to see if the pieces are crunchy. Keep in mind if they are still warm, they may still seem a little wet. If you are unsure remove the mixture from the oven, allow it to cool before testing it again. If it still needs a bit more time throw it back in checking the mixture every 5-10 minutes. Enjoy
