You'll need a 9x12 baking dish.
It's easy to half the recipe too if you want a smaller batch...just use a 9x9 baking dish.
2 cups Flour
2 cups Granulated Sugar
3/4 cup cocoa powder
1 tsp baking powder
1 tsp salt
1 cup water
1 cup oil
1/2 cup almond milk (or any milk alternative)
1 1/2 tsp vanilla extract
1/4 cup cookie dough
Pre-heat oven to 350 F.
In a large bowl, combine the flour, sugar, cocoa powder, baking powder, and salt.
Heat the water in a small saucepan on medium heat until almost coming to a full boil.
Remove from heat.
Add oil to the dry mix, then pour the water and vanilla extract in as well. Continue stirring to combine. Add the milk last and stir well until all mixed together.
Pour into a 9x12 baking dish. Take cookie dough and put small glops on top in different areas of the batter. Then take a butter knife and cut in through the batter before baking.
Bake for 30 minutes or until a toothpick inserted in the center of the brownie comes out clean.
Let fully cool and let your mouth have the time of it's life. Because it will.
