Ingredients
Scale
Main Ingredients
- 2/3 cup butter
- 2 tbsp vegetable oil
- 3/4 cup granulated sugar
- 1/4 cup brown sugar
- 2/3 cup cocoa powder
- 2 eggs, cold
- 1 tsp vanilla extract
- 1/2 tsp salt
- 2/3 cup all purpose flour
- 1/2 cup semi-sweet chocolate chips
Spider Web Decoration (Optional)
- 3/4 cup mini marshmallows
Instructions
- Preheat and prepare pan: Preheat the oven to 350F and line an 8×8 inch baking pan with parchment paper. Set aside.
- Melt and mix wet ingredients: In a microwave-safe bowl, melt the butter, vegetable oil, granulated sugar, brown sugar, and cocoa powder together in 30-second intervals, stirring after each. Once melted, microwave for an additional 1 minute and stir vigorously to fully dissolve the sugars and emulsify the fats.
- Add eggs and vanilla: Whisk the cold eggs in one at a time, then add the vanilla extract. Mix until the batter pulls away slightly from the bowl.
- Incorporate dry ingredients and chocolate chips: Add the flour and salt, folding gently just until combined. Fold in the semi-sweet chocolate chips evenly.
- Bake the brownies: Pour the batter evenly into the prepared baking pan and bake in the preheated oven for 30 minutes.
- Cool before slicing: Remove from oven and allow the brownies to cool completely on a wire rack to achieve a perfect crinkly top and clean slices.
- Create spider web decoration (optional): Melt the mini marshmallows in the microwave for 20 seconds, stir well, and let cool for 1-2 minutes. Using two forks, carefully pull the marshmallow mixture over the cooled brownies to create a spider web effect. Alternatively, use your hands if the mixture is cool enough.
Notes
- Ensure eggs are cold for best texture in the batter.
- Use parchment paper to easily lift brownies from the pan and for easy cleanup.
- Do not overmix after adding flour to keep brownies tender.
- For extra fudgy brownies, slightly underbake and check with a toothpick.
- If marshmallow mixture is too hot to handle, wait longer before shaping spider webs.
- Substitute semi-sweet chocolate chips with dark or milk chocolate according to preference.
