Perfect Fudgy Brownies Recipe (Print Version)

# Ingredients:

01 - 10 tablespoons (145g) unsalted butter.
02 - 1 ¼ cups (250g) granulated sugar.
03 - 3/4 cup plus 2 tablespoons (75g) unsweetened cocoa powder, spooned and leveled.
04 - 1 teaspoon vanilla extract.
05 - 1/4 teaspoon fine sea salt.
06 - 2 large cold eggs.
07 - 1/2 cup (65g) all-purpose flour, spooned and leveled.
08 - 2/3 cup (80g) chopped walnuts, pecans, or chocolate chips, optional.

# Instructions:

01 - Position an oven rack in the middle of the oven and preheat to 325°F (162°C). Line an 8-inch square baking pan with parchment paper or aluminum foil, allowing it to hang over the sides for easy removal.
02 - In a medium saucepan, melt the butter over medium-low heat until fully liquefied. Remove from heat and avoid browning.
03 - While the butter is still hot, stir in the sugar, cocoa powder, vanilla, and salt until the mixture is smooth. It's okay if the texture seems gritty initially.
04 - Let the mixture cool until it's warm to the touch, about 5 to 10 minutes. The batter should feel comfortable when touched.
05 - Add the cold eggs one at a time, stirring vigorously after each addition until the batter is thick and well blended.
06 - Gradually add the flour, beating the batter with a wooden spoon or spatula for about 40 to 50 strokes until it pulls away from the sides.
07 - Fold in nuts or chocolate chips if using.
08 - Spread the thick batter evenly into the prepared pan. It may be challenging to spread due to its density, so use a spatula to smooth it out.
09 - Bake for 20 to 30 minutes, until the edges appear dry and the center is slightly underbaked. A toothpick inserted should come out a bit moist.
10 - Allow the brownies to cool completely in the pan before lifting them out. This ensures they set properly.
11 - For clean slices, chill the brownies in the fridge for 1 to 2 hours and cut into 16 squares using a clean, sharp knife.

# Notes:

01 - Store the brownies in an airtight container at room temperature for 2 to 3 days or refrigerate for up to 2 weeks. They can also be frozen for up to 3 months.
02 - A metal 8-inch square pan is recommended; ceramic or glass may affect baking time.
03 - The recipe can be doubled for a 9x13-inch pan, resulting in slightly thicker brownies.
04 - For a more intense flavor, try using Dutch-process cocoa for a smooth, Oreo-like taste or natural cocoa for a deep, dark chocolate essence.
