Here we go! First things first, in a large bowl mix together the Cheerios, Shreddies, pretzels, peanuts, cheezits, pecans and goldfish. Set aside.
Pre-heat the oven to 250F.
Next, melt the butter, mix in the Worcestershire sauce, olive oil, maple syrup, garlic powder, paprika, chilli powder, sugar, and salt. Whisk until incorporated.
Place the dry cereal mixture in a large roasting pan, and pour the melted butter mixture over everything. Using a spatula and your hands, toss until the whole mixture is coated with the melted butter.
Place the roasting pan into the oven for 1 1/2 to 2 hours, tossing the mixture with a spatula every 25 minutes.
After the mixture is done baking, remove pan from the oven and let it cool to room temperature. Now, eat!
