Begin by mixing 1/4 cup water with the ground flax. Let sit for a few minutes while you complete the next steps.
Preheat the oven to 350 degrees.
Cream the sugars and butter together until well blended, smooth, and fluffy. 5-10 minutes.
Add in molasses, vanilla, and eggs, mixing well after each one.
In a separate bowl combine the flour, almond meal, hemp hearts, salt, baking soda, and cinnamon.
Mix the dry ingredients into the wet with a sturdy spoon.
Lastly, add in the oatmeal and your mix-in of choice...fruit, nuts, or chocolate chips.
Grease the 9x13 pan with butter, be sure to get the bottom and sides well covered.
Place a layer of parchment paper on the bottom of the pan.
Scoop the batter out and spread evenly across the pan. It is pretty thick so this will take a little doing.
Bake for 30-40 minutes.
Allow the bars to cool in the pan, then slice in the pan or flip onto a cutting board.
I like to cut them in various sizes so I have an option for what size bar I might be hungry for.
Store in the freezer for up to three months or the fridge for a few weeks.
