Ingredients
[19x19cm (7.5 inch) square pan]
Unsalted Butter: 110g (1/2 cup)
Eggs: 3
Granulated Sugar: 150g (3/4 cup)
Dark Brown Sugar: 50g (1/4 cup)
All-Purpose Flour: 65g (1/2 cup)
Cocoa Powder (unsweetened): 25g (1/4 cup)
Salt: 1/4 tsp
Vanilla Extract: 1 tsp
Instructions
Preheat the Oven:
Preheat your oven to 175°C (350°F).
Prepare the Chocolate Mixture:
In a heatproof bowl, melt the dark chocolate and unsalted butter together until smooth. You can use a microwave or a double boiler method.
Mix the Sugars and Eggs:
In a separate large bowl, whisk together the granulated sugar, dark brown sugar, and eggs until light and fluffy.
Combine the Mixtures:
Slowly pour the melted chocolate mixture into the sugar and egg mixture, stirring continuously to combine.
Add Dry Ingredients:
Sift in the all-purpose flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet mixture until just combined. Do not overmix.
Add Vanilla Extract:
Stir in the vanilla extract until evenly incorporated.
Pour into Pan:
Pour the batter into a greased or parchment-lined 19x19cm (7.5 inch) square pan and spread it evenly.
Bake:
Bake in the preheated oven for 20-25 minutes. To achieve a crackly top, tap the pan gently on the counter after 20 minutes and continue baking until done.
Cool:
Remove the brownies from the oven and let them cool completely in the pan on a wire rack.
Refrigerate (Optional):
For an even better texture, place the cooled brownies in an airtight container or wrap them in plastic wrap and refrigerate for at least an hour before serving.
Tips
Preheat the Oven: Always bake in a preheated oven for the best results.
Sugar Replacement: You can replace granulated sugar and dark brown sugar with light brown sugar.
Adjust Sweetness: If the brownies are too sweet for your taste, reduce the sugar by 20g.
Crackly Top: Tap the pan gently after 20 minutes of baking for a crackly top.
Quality Ingredients: Use high-quality dark chocolate and cocoa powder for the best flavor.
Refrigeration: The brownies taste even better when refrigerated in an airtight container.
Enjoy these decadent, fudgy brownies! Perfect for any chocolate lover.
