|Heat oven to 300 degrees. Line a large 17x14-inch cookie sheet or 2 (15x10x1-inch) pans with foil; spray foil with cooking spray. In large bowl, mix both cereals, the oats and almonds; set aside.|
In a 1-quart saucepan, heat butter, brown sugar and syrup over medium heat, stirring frequently, until butter is melted and mixture boils. Pour over cereal mixture; stir until well coated. Spread mixture evenly on cookie sheet with rubber spatula until about 1/2 inch thick.
Bake 35 to 40 minutes or until almonds are golden brown. Cool completely, about 15 minutes. Break into pieces with fingers. Store in tightly covered container. Makes 14 servings (1/2 cup each).
