Preheat oven to 375ºF.
Line a jelly roll baking pan with aluminum foil and spray with cooking oil.
In a large mixing bowl, stir together the flaxseed meal, gluten-free flour, oats, cinnamon, carrots, fruits and nuts of your choice (in similar proportions to those listed above). When fully combined, stir in the agave nectar, applesauce, molasses, nut butter, and juice, mixing with a large wooden spoon until totally incorporated. The mixture should be wet enough to press together for baking.
If you like your granola bars with lots of crunchy texture, use this wooden spoon or stand mixer (with flat paddle) mixing method. If you prefer a smoother texture, where the individual ingredients are more integrated, use a large food processor to combine all the ingredients — if your processor bowl is 14 cups or smaller, this may have to be done by dividing the ingredients in half and mixing in two batches.
Scoop the combined mixture into the bottom of the prepared baking pan and press down with the back of a rubber spatula or your wet hands.
Bake for 30 minutes or just until the edges begin to brown slightly.
Remove from the oven and cut into bars using a pizza cutter before fully cooled. To remove bars when cooled, simply lift the foil edges out of the jelly roll pan and store the cut bars in a zip top bag at room temperature or freeze.
