Preheat the oven to 350°F.
Line a 8x11 baking pan (***see note) with parchment paper and leave enough hanging over the sides to use as your "handles" later.
Whisk together the flour, flaxmeal, sugar and salt in a small mixing bowl and set aside.
In a medium mixing bowl, stir together the pecan butter, maple syrup and vanilla until smooth.
Stir the dry ingredients into the wet until well combined. Use your hands and really get in there to mash it all together.
Press the mixture into the prepared baking pan and flatten it down with the palm of your hand.
Bake for 20 to 25 minutes until the top starts to firm up.
Sprinkle on the chocolate chips and bake another 2 to 3 minutes until the chocolate gets melty.
With an off set spatula, spread out the chocolate evenly over the bars.
Immediately sprinkle with the chopped pecans.
Leave the bars in the baking pan on a wire rack for at least 10 to 15 minutes. They will continue to firm up as they cool.
Using the parchment paper "handles" lift the whole thing out of the pan and set on the wire rack to continue cooling all the way.
Cut into bars and enjoy!
