Notes
Chocolate Chips. Add 1/4 cup of mini chocolate chips to batter.
Nutella Swirl. Take 2 tablespoons of Nutella and drop by teaspoons onto the top of the brownie batter after it is in the pan. Take a knife and swirl through the batter and the Nutella.
Flaky Salt. Use some flaky sea salt, I like Maldon, and sprinkle lightly on the surface of the brownies before baking.
