Preheat the oven to 350°F
In a medium sized, microwave-safe bowl (big enough for the brownie batter), melt the oil and HALF (60 g) of the chocolate chips in the microwave
Once melted, add the rest of the wet ingredients and mix until combined – it's okay if it's a little lumpy
Add the dry ingredients to the wet and mix until smooth
Fold in the remaining chocolate chips, then evenly spread the batter into a prepared 8x8 or 9x9 square baking pan
Remove the cookie dough from the fridge and using a measuring spoon, spoon, or your hands, scoop out ~½ TBSP sized pieces of cookie dough and lightly press the pieces into the brownies, spreading them out evenly – it doesn't need to be perfect, you can make them as big or small as you'd like
Bake for 17-20 minutes or until a toothpick can be inserted into the center and come out clean; for gooier brownies, remove around 15-16 minutes and let cool before cutting
