In a large mixing bowl, combine 5 cups Chocolate Chex cereal, 5 cups Cocoa Puffs cereal , 4 cups Golden Grahams cereal, 1 cup shredded sweetened coconut, and 1 cup almonds.
In a saucepan, combine 1 cup light corn syrup , 1¼ cup salted butter, and 1 cup white granulated sugar. Over medium heat, bring mixture to a gentle boil, stirring constantly. Boil for 2 minutes while stirring.
Remove from heat and add in 1 teaspoon vanilla extract.
Pour over cereal mixture, and stir in gently with rubber spatula, being careful not to crush the cereal. Spread in a layer over greased parchment paper to cool to speed up the cooling process.
Notes
Note 1: Toast coconut on a parchment paper lined baking sheet in oven preheated to 350℉ for 5-7 minutes, stirring occasionally. You can toast for a few more minutes for a more brown color. Store in an airtight container for up to 5 days at room temperature.
