Preheat oven to 350° (177 °c) and lightly grease a 10 inch (25 cm) iron skillet.
Whisk the flax seed and water together and let sit.
In a medium bowl, whisk the flour, baking soda, and sea salt together until well blended.
In a large mixing bowl, beat the butter and sugars together until combined, add the vanilla, maple syrup, and flax egg and mix until light and fluffy. Slowly add the flour into the mixture and mix until just blended. Fold in the chocolate chunks and spread evenly in the pan.
Bake on the middle rack for 15 to 18 minutes, or until golden brown and firm in the middle. Serve with a scoop of cashew vanilla ice cream.
