Preheat your oven to 350°F. Lightly grease an 8-inch square baking pan.
Place oats in a food processor, and pulse them just briefly to break them down a bit; three 1-second pulses should do the trick. Transfer oats to a large bowl along with almonds and flour. Stir to combine.
In a separate bowl, mix together brown sugar, oil, maple syrup, vanilla, cinnamon, and salt until smooth. Add these liquid ingredients into the bowl of dry; and stir well.
Pour the mixture into your prepared pan, and firmly and evenly pack it down.* Bake for 22 to 25 minutes, or until the entire top is amber.
Score into bars immediately after removing the pan from the oven, and let cool. To reduce crumbling, wait until the granola bars have reached room temperature before you cut them.
Quick Tip: To quickly and easily pack the granola bar mixture into the pan, lightly grease the bottom of a measuring cup. Use it to smooth and press the mixture firmly into place.
