Preheat oven to 350°F (177°C). Lightly grease and line a 9 x 13-inch pan with parchment paper, ensure that the longer sides have about a 2-inch overhang for easy unmoulding.
In a large bowl, whisk together the Redpath® Dark Brown Sugar, Redpath® Special Fine Granulated Sugar, flour, cocoa powder, and until no lumps remain.
In a separate large bowl, whisk together the melted butter, lightly beaten eggs, and extracts.
Add the dry ingredients to the wet and fold with a large rubber spatula until everything is well combined.
Pour and evenly spread the brownie batter into the prepared baking pan smoothing out the top with a small offset spatula. Place into the preheated oven; 25 to 30 minutes, or until set. Err on the side of under-baking to avoid dry brownies.
Remove pan from the oven and place onto a wire cooling rack to cool completely.
