In a large microwave safe bowl, add peanut butter, honey, and coconut oil. Microwave for approximately 30-40 seconds and stir to combine.
Using a food processor, add flax seeds dates and walnuts (see note 1). Pulse until a course mixture forms.
Add the date and walnut mixture to the wet ingredients, add oats, and stir to combine. Press evenly into the prepared baking pan. Refrigerate the bars for at least 15-20 minutes, until the bars are set.
Slice the bars into 10 servings and either individually wrap or store in an airtight container in the fridge or freezer (note 2).
Flax seeds: to grind them up more, add them to your food processor or small blender first before adding the additional ingredients.Storing the Bars: Wrap the bars individually for easy grab-and-go convenience and store them in the fridge, as they are a little softer than baked granola bars. You can also freeze the bars. I've used both walnuts and pecans in these bars, they both have a good amount of fiber yet a little fat to keep you full, too. Use whichever you prefer.If you don't have a food processor, you can chop the nuts and dates by hand and mix in the flax seed whole.
