In a large bowl, measure out 4 cups of the cereal. Set aside.
Line an 8x8 baking pan with parchment paper and set aside.
In a small saucepan, add the almond butter, coconut nectar, coconut sugar, and salt. Cook over medium heat, stirring to combine all of the ingredients. When the mixture begins to softly boil, let it do so for about 1 minute as you continue stirring. Remove from heat and stir in the vanilla.
While caramel is cooking, place the cereal in a large plastic bowl. Pour the caramel mixture over the cereal and stir with a silicone spatula until all of the pieces are coated well.
Turn the mixture out into the parchment-lined pan and press it into the pan evenly with the back of the spatula. Place in the freezer for at least 2 hours to harden up. Then, lift out the parchment paper, and place it on a cutting board. Cut into 9 squares. Serve!
