1. Place cereal and raisins in a large mixing bowl. Heat almond butter and agave nectar over medium-low heat until the mixture is warm and thinned like syrup. Remove from heat and stir in vanilla and cinnamon. Pour over cereal and raisins and stir until completely coated. 2. Spray a 7-by-11-inch baking dish with natural cooking spray. Transfer the cereal mixture to the baking pan. Pat it down with wet fingers to even out the top. Chill for an hour before cutting into squares. Keep chilled between servings.
