Preheat the oven to 350 degrees Fahrenheit.
Add the butter or coconut oil to the microwave and melt for about 20-30 seconds. You want it at the point where it's just melted and no clumps remain.
In a large mixing bowl, combine the oil and all remaining wet ingredients. Whisk together until combined.
Add in the dry ingredients and mix together until a batter forms. Fold in the chocolate chips and mix.
Transfer to an 8x8 pan lined with parchment paper. Spread evenly throughout the pan and sprinkle on additional chocolate chips if desired.
Bake for 18-25 minutes. 18 minutes will yield bars that are a bit gooier, but 25 minutes the bars will be more well done.
Let cool completely (annoying but important!) before slicing. Serve as is or with a scoop of vanilla ice cream!
You can safely use a 9x9 dish if that's all you have, just know the bars will be thinner and you will need to adjust the baking time slightly. Check the bars around 18 minutes.
You can swap the light brown sugar for coconut sugar to make these bars refined sugar free if you prefer. Dark brown sugar should also be ok.
I highly recommend using quick oats for this recipe. Rolled (old fashioned) oats will work, but they give the bars a grainier texture that I personally am not a huge fan of. You can also do half and half if you like a bit more texture.
I like using butter in this recipe, but if you're using coconut oil, just make sure it is refined so you don't have any coconut flavor.
I have not tested this recipe with an egg replacer, but I do think it would work. Brownies, blondies and bars of all kind are generally pretty forgiving, so I would suggest either using apple sauce (3 tablespoons for each egg) OR use flax eggs. To make the flax eggs combine 1 tbsp of ground flax or flax meal with 2 1/2 tablespoons of water. Set aside to thicken, that mixture will equal one egg.
