Best Cocoa Fudge Brownies (Print Version)

# Ingredients:

→ Dry Ingredients

01 - 1 cup (120g) all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/2 teaspoon salt
04 - 1/2 cup (43g) unsweetened cocoa powder
05 - 1 teaspoon espresso powder (optional)

→ Wet Ingredients

06 - 3/4 cup (170g) unsalted butter
07 - 2 tablespoons (28ml) oil (canola, vegetable, or coconut)
08 - 1 and 1/3 cups (265g) granulated sugar (divided)
09 - 2 large eggs
10 - 1 large egg yolk
11 - 2 teaspoons vanilla extract (optional)

→ Mix-ins

12 - 3/4 cup (128g) chocolate chips

# Instructions:

01 - Preheat oven to 175 degrees C (350 degrees F). Line a 9x9-inch baking pan with parchment paper and lightly spray with non-stick baking spray. Set aside.
02 - In a large bowl, sift together the flour, baking powder, salt, cocoa powder, and espresso powder. Set aside.
03 - In a medium saucepan, combine the butter, oil, and 1/3 cup of the sugar. Heat over medium, stirring frequently, until the butter melts completely. Remove from heat.
04 - In a large mixing bowl, whisk together the eggs, egg yolk, vanilla (if using), and remaining sugar for about 30 seconds until well combined.
05 - Slowly pour the warm butter mixture into the egg mixture, adding it gradually while whisking constantly until fully combined.
06 - Gently fold the dry ingredients and chocolate chips into the wet mixture using a rubber spatula. Stop mixing when the last traces of dry ingredients disappear. Avoid overmixing to prevent cakey brownies.
07 - Pour the batter into the prepared baking pan and smooth the top evenly.
08 - Bake for 28-30 minutes, or until the edges are firm and the top is shiny and slightly cracked.
09 - Place the pan on a cooling rack and cool completely before slicing. Adjust bake time as needed for desired gooeyness or structure.

# Notes:

01 - To achieve gooey brownies, bake closer to 27 minutes; for more structured ones, bake for 30-32 minutes.
02 - Overmixing the batter is the main reason brownies turn out cakey instead of fudgy.
