Preheat oven to 350 degrees F.
Line an 8×8 pan with parchment paper.
Melt 1 stick of butter in a pan and cook on low heat until browned, stirring occasionally to make sure it doesn't burn. You'll know the butter is ready when it's foamy, deep brown, and has a nutty flavor. Pour the butter into a glass dish to cool for 10 mins. (You can skip this step if you're using olive oil.)
In a large bowl, whisk together all dry ingredients.
In the same bowl, add all of your wet ingredients. Then, fold in 3/4 cup of the chocolate chips.
Spread the batter into the pan. Sprinkle the rest of the chocolate chips on top
Bake for 20-30 mins (baking time widely depends on your oven. You want the edges to be golden and the center to be gooey but not raw.)
Allow the bars to cool for itlest 15 mins before slicing. Top with flakey sea salt and serve with ice cream of choice!
