This version turned out to be a crispy corn flake cereal with oat clusters and a hint of brown sugar sweetness. It goes perfectly with milk (almond milk for me) or as a topping on yogurt.
Preheat oven to 275 degrees. Mix everything together is put on a parchment lined baking sheet. Bake at for 45 minutes to an hour stirring every 15 minutes. It will crisp up more once it cools.
