My chef-tested, Best Ever Brownies recipe are everything you'd want in a homemade brownie: ooey-gooey, fudge-like, and oh so delicious!
Preheat the oven to 350°F (180°C) and line a 9x13 inch (23 x 33 cm) baking pan with parchment paper. Set aside.
In a large bowl combine the melted butter, oil, brown sugar and granulated sugar.
Add the eggs, vanilla and salt, then whisk for about one minute until evenly combined and light in color.
Sift in the flour and cocoa powder over the butter mixture. Gently fold the dry ingredients into the wet ingredients until JUST combined (do NOT over mix). Fold in half of the chocolate chunks.
Pour the batter into the prepared pan, then smooth the top. Top with the remaining chocolate chunks.
Bake for 35-40 minutes, or until the center of the brownies no longer jiggles and is JUST set to the touch.
Remove from the oven and allow to cool to room temperature before removing from the baking tray and slicing into 16 brownies. Enjoy!
Store leftovers in an airtight container at room temperature for up to 3 days.
