Whisk together the flax meal with 5 tbsp of then hot water and set aside until it forms a gel, about 10 minutes. Give it a stir every few minutes.
Heat your oven to 350 degrees F and line the bottom of an 8x8 inch baking pan with parchment paper, spraying the sides with cooking spray.
In a large, microwave-safe bowl, microwave the butter, oil and sugar until the butter is melted. About 1-1.5 minutes. Stir well until the mixture starts to come together and make ribbons on itself - about 1-2 minutes.
Add in the flax seed, the remaining 1 Tbsp of hot water and the vanilla and stir well.
Add all the ingredients up to the chocolate chips and stir just until mixed. Gently fold in the chocolate chips.
Spread into the prepared pan and bake until the top feels set and forms some cracks and a toothpick inserted in the center comes out clean (except for possible melted chocolate chip. It shouldn't be gooey.) about 30-35 minutes.
Immediately place the brownies on a cooling pad in the refrigerator for 15 minutes.
Remove from the fridge and let cool on the counter COMPLETELY.
Gently cut and remove from the pan (they're fragile so be nice!) and DEVOUR!
