A super easy, super fudgy ONE BOWL treat!
In a medium-sized bowl, combine melted butter, oil and sugars and whisk well for about a minute. Add the eggs and vanilla; beat until lighter in color (at least another minute).
In the same bowl, add flour, cocoa powder, and salt. Gently stir the dry ingredients through the wet, until JUST combined (Be careful to not over beat.)
Bake for 25-30 minutes, or until the centre of the brownies in the pan no longer jiggles.
Remove and allow to cool to room temperature before slicing into 12 brownies.
Important: Once you add the flour and cocoa powder, do NOT over beat your batter or it could affect the texture of the brownies.
