Preheat the oven to 300°F. Line a large sheet pan with parchment paper.
Combine oats, almond flour, sliced almonds, cinnamon, and salt in a large bowl.
Melt the coconut oil in a separate medium bowl. Whisk in the brown sugar, maple syrup, vanilla extract, and almond extract. Alternately, you can use a small saucepan to melt the coconut, sugar, and syrup oil over medium heat.
Pour the wet ingredients over the oat mixture and stir with a rubber spatula to combine, making sure all of the oats are covered in the mixture. It will be sticky.
Dump the granola mixture into the prepared pan and use a rubber spatula to spread and press it down firmly into an even layer.
Bake in the preheated oven for 35 minutes, rotating halfway through for even cooking. Do not stir the granola.
Remove it from the heat and allow it to cool slightly for 10 minutes. Carefully use your hands to break the granola up into big or small clusters, depending on preference. Bake for an additional 5 minutes, until the granola is toasty and golden brown.
Remove from the oven and allow them to cool completely before serving. It will get crunchier as it cools. Leftover granola stays fresh in an airtight container at room temperature for up to 1 week or in the freezer for up to 3 months.
