Preheat oven to 350 F and grease a 13×9 baking dish.
Mix together the brownie mix, oil, water, and 2 eggs until completely combined.
Pour into the baking dish.
Beat the cream cheese in a bowl until creamed, then add 1 egg, sugar, and almond extract until completely mixed. Pour on top of the brownie mix and smooth it all over top.
Using a fork or knife, drag it through the cream cheese layer to make lines with the brownie mix. Bake for 35-40 minutes.
Once it’s cooled, use the decorative gels to recreate your favorite Banksy art.
