Equipment

9x13-inch baking pan
Mixing Bowl
Whisk
Spatula

Ingredients

1 cup Unsalted butter, melted
2 cups Granulated sugar
4 large Eggs, room temperature
2 teaspoons Vanilla extract
1 cup All-purpose flour
1 cup Unsweetened cocoa powder
1 teaspoon Baking powder
1/2 teaspoon Salt
1 cup Chocolate chips
1 cup Walnuts, chopped (optional) Can be substituted with pecans or omitted for nut-free version.

Instructions

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan with butter or nonstick spray. Lining the pan with parchment paper and leaving an overhang makes removing bars easy later.
In a large bowl, mix together the melted butter and sugar until well combined. Use a wooden spoon or a hand mixer on low to fully incorporate the sugar into the butter so it feels smooth.
Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract. Take your time to mix after each egg so the batter becomes glossy and slightly thickened.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Sifting the cocoa and flour helps avoid lumps and ensures even mixing.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Do not overmix — stop when no streaks of flour remain.
Fold in the chocolate chips and walnuts (if using). Reserve a small handful of chips to sprinkle on top if you like a pretty finish.
Pour the batter into the prepared baking pan and spread it evenly with a spatula. Smooth the top so the bars bake uniformly.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs but not raw batter. The edges should be set and the center slightly gooey. Remove from oven and allow to cool completely in the pan before cutting into bars for clean slices.

Notes

For extra fudginess, slightly underbake: aim for 25 minutes and test with a toothpick. Let bars cool fully in the pan; cutting too soon can make them fall apart.
