Trogdor, the Chex Mix

My Grandpa, who is like Trogdor, loves spicy Chex Mix. So about a year ago, I made him Hot and Spicy Chex Mix, but it really wasn't hot enough for him. Like I said, he's like Trogdor. Since then I've been slowly adapting the recipe to get it up to the burning level he needs. I think I'm just about there. Here's the latest version.

Trogdor, the Chex™Mix

3 cups Corn Chex™ cereal
3 cups Rice Chex™ cereal
4 cups Wheat Chex™ cereal (because the Wheat Chex are the best)
1-1/2 cups mixed nuts
2 cups pretzels
2 cups Hot & Spicy Cheez-It™ crackers
2 cups Flaming Hot Cheetos™
5 Tbsp butter
1 Tbsp Worcestershire sauce
2 tsp seasoned salt
1/2 tsp garlic
4 tsp sriracha hot sauce
2 tsp jalapeño powder

In a large microwavable bowl, combine the cereals, nuts, pretzels, crackers and Cheetos™. Set aside. In a small microwavable bowl, melt the butter (about 30-45 seconds). Stir in the Worcestershire sauce, salt, garlic, sriracha hot sauce and jalapeño powder. Pour over cereal mixture. Stir until well coated. Heat in the microwave for 6 minutes, stirring every 2 minutes. Spread Chex™Mix out on paper towels until cool. Store in an air tight container.
