In a food processor, pulse the puffed rice cereal until small pieces form. In a shallow dish, combine the cereal, granulated sugar, and cinnamon. Set aside.
In a medium bowl, whisk together the eggs, heavy cream, milk, and vanilla. Dip each stick of bread into the egg mixture then using a clean hand, dip into the cereal mixture until coated on all sides. Shake of excess and place the coated sticks on a baking dish. Repeat the dipping process with the remaining sticks.
Heat a large skillet or sauté pan over low-medium heat. Add a small pad of butter and bit of oil. Once the butter has melted, add 5 sticks in a single layer into the pan. Make sure you don't over crowd the pan. Cook until golden brown on one side and flip and continue cooking until the sticks are golden on crispy on all sides.
Serve immediately with maple syrup, fresh fruit, and sprinkled with powdered sugar.
