A decadent and rich brownie elevated adding crumbled Oreo pieces throughout the batter as well as on top before baking creating a delicious take on a timeless classic.
Set oven rack to middle position and preheat oven to 350 degrees Fahrenheit.
Line a 9X9 aluminized brownie pan parchment paper including up the sides and grease with butter.
In a medium mixing bowl combine melted butter and sugar and combine with a whisk.
Add eggs, vegetable oil and vanilla and whisk to combine.
Add flour, cocoa powder and salt and fold into the wet ingredients using a spatula until only a small amount of visible flour is left unmixed.
Add half of the crumbled Oreo pieces and continue folding into the batter.
Pour batter into the parchment and greased lined brownie pan and spread evenly using a spatula.
Add remaining crumbled Oreo pieces on top and slightly press down into the batter.
Bake for 45 minutes until edges are slightly starting to darken and middle is set.
