Line two large rimmed baking sheets with parchment paper. Set aside.
In a very large bowl, combine Rice Chex cereal, Golden Grahams cereal, coconut and almonds. Gently stir to combine. Then divide cereal mixture evenly into two large bowls. Set aside.
In a medium saucepan, melt butter over medium-high heat. Once butter is melted add the granulated sugar and corn syrup. Stir continuously until mixture comes to a soft boil.
Once boiling, set a timer for two minutes. Remove from heat after two minutes. Quickly stir in vanilla extract.
Carefully, (it will be very hot) pour half of the syrup mixture over each bowl of the cereal mixtures. Gently stir to coat cereal. Pour each bowl out over prepared baking sheets. Let stand a few minutes to cool then dig in and enjoy!
