How to make a black cocoa fudgy brownie recipe
This is how you can make these dark chocolate brownies. Make sure to scroll down to the recipe card for the full detailed instructions!
- Line your with parchment paper and set aside. Keep in mind that leaving some overhand on the sides of the pan will make it easier to pull the brownies out.
- Add the butter, oil, brown sugar, and white sugar to a large microwave-safe bowl.
- Microwave for 60 seconds then whisk to get everything well combined. The mixture will thicken but don’t worry about it!
- Add in the eggs one at a time then whisk to get them combined well each time.
- Mix in the vanilla extract until combined.
- Add in the flour and salt and mix until the dry ingredients disappear.
- Fold in the chocolate chips and pour the batter into a parchment-lined square pan.
- Bake in the preheated oven.
- You can enjoy your brownies as is or decorate them with melted marshmallows and spider chocolates to make them fit the Halloween vibes! I also love to top them with a sprinkle of sea salt for that sweet and salty vibe to bring out the chocolate flavor even more.
If you decide to make spider webbing on top of these brownies so you can serve them for Halloween, melt the marshmallows in a medium bowl then using either forks or your fingers (if you can handle the heat and move quickly) pull the melted marshmallows over the brownies to create that webbing effect.
Tips and tricks to make sure your brownies get rave reviews every time!
- Use room temperature ingredients– Using room temperature ingredients will ensure that everything will be mixed and emulsified properly within the batter of these brownies.
- Do not overbake your brownies– No one likes a dry brownie and the best way to keep that from happening is to slightly underbake your brownies because they will keep baking as they cool down. When checking for doneness, you want to insert a toothpick or wooden skewer in the center of the brownie itself and have it come out with some fudgy moist crumbs only. We don’t want the toothpick to come out with wet batter because that would indicate that the brownie is not baked fully, but a few crumbs are what we want!
- Allow your brownies to cool down fully before slicing into them– I know how tempting it is to dig into these perfect brownies but trust me when I say allowing them to cool down before slicing will give you a more perfect slice and will allow the flavors to deepen and settle some more. If you don’t mind for having those sharp square pieces, feel free to dig in, or even serve spoonfuls of this in a bowl with a scoop of ice cream.
