PREP: position a rack in the center of the oven and preheat the oven to 300ºF. Line a large rimmed sheet pan with parchment paper and set aside for now.
MIX: In a large mixing bowl, combine the rolled oats, sliced almonds, coconut, chia seeds, powdered milk, kosher salt, and cinnamon.
STIR: In a glass measuring cup or small mixing bowl, add the melted butter, coconut oil, brown sugar, maple syrup, egg whites, almond butter, vanilla bean paste and stir to combine.
TOSS: Pour the wet ingredients over the oat mixture and toss using a spatula until all the dry ingredients are covered evenly.
SPREAD: the granola mixture out onto the parchment paper-lined baking sheet in an even layer.
BAKE: the granola for 15 minutes. Remove from the oven, and give it a toss. Bake again for 7 minutes. Then remove and toss one last time. Bake for another 2-7 minutes or until the granola is deeply golden. It’ll still be soft, but will harden as it cools. Remove and let the granola cool for 10 minutes.
ADD: the half the chocolate chips and stir. They’ll melt a little and kind of hold the whole thing together. Add the remaining chips once cooled if you want to see them in the granola.
STORE: Once completely cooled, transfer in to an air tight container. Granola can be kept at room temperature in an airtight container for up to a month.
