Set oven rack to middle position, and preheat oven to 325 °F. Finely grind 2 tablespoons of old-fashioned oats using a spice grinder or food processor. In a large bowl, whisk together ground oats, remaining 1.5 cups old-fashioned oats, steel-cut oats, and pecans.
In a medium bowl, whisk together brown sugar, coconut oil, maple syrup, cinnamon, cloves, salt, vanilla, and orange oil. With a rubber spatula, fold sugar mixture into oat mixture until evenly distributed.
Transfer granola to a parchment-lined baking sheet. Press granola into an even layer. Continue pressing granola from center out towards edges to create a thin tightly packed layer, less than ½-inch thick. Make sure the edges are as thick and tightly packed as the center. It is worth taking a few extra minutes to do this thoroughly.
Bake granola until edges are firm, and center gives only slightly when pressed; oats are light golden brown, and nuts are dark; granola smells fragrant and toasty; about 30 minutes, rotating baking sheet halfway through.
Transfer baking sheet to a cooling rack; allow granola to cool completely. Break granola into 2-inch chunks, and sprinkle dried cranberries over the top. Store granola in an airtight container for up to a month.
