These Halloween brownies are made with simple ingredients in less than sixty minutes for a decadent, fudgy dessert that’s almost as fun to make as it is to eat!
Before you begin, preheat your oven, line a baking pan with foil or parchment paper, and grease it with nonstick cooking spray.
In a large microwave-safe bowl, add the butter and sugar, and microwave just until the butter is melted. Add the oil, and stir to combine.
In the same bowl, add the eggs and vanilla, and whisk until smooth. Sift the flour, cocoa powder, cornstarch, and sea salt into the bowl of wet ingredients. Gently stir just until the ingredients are fully incorporated and no streaks remain.
Spread the brownie batter in an even layer in the prepared pan, and sprinkle your toppings of choice on top.
Place the pan in the preheated oven, and bake just until the brownies are set and a cake tester or toothpick can be inserted into the center and comes out clean.
Remove the brownies from the oven, and allow them to cool completely in the pan. Enjoy!
