Ingredients

• 1 cup unsalted butter (melted)
• 2 cups granulated sugar (can reduce to 1.5 cups for less sweetness)
• 1 cup brown sugar (light or dark brown sugar works)
• 4 pieces large eggs (room temperature)
• 2 teaspoons vanilla extract (pure vanilla is best)
• 1 cup all-purpose flour (spooned and leveled)
• 1 cup unsweetened cocoa powder (use quality cocoa for best flavor)
• 1 teaspoon salt (to enhance the chocolate flavor)
• 1 cup chocolate chips (optional, can use semi-sweet or dark chocolate)

Instructions

1. Step 1: Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan or line it with parchment paper.
2. Step 2: In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
3. Step 3: Add the eggs one at a time, whisking well after each addition, then stir in the vanilla extract.
4. Step 4: In a separate bowl, combine the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring just until combined. Do not overmix.
5. Step 5: Fold in the chocolate chips if using.
6. Step 6: Pour the brownie batter into the prepared baking pan and spread it evenly.
7. Step 7: Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.
8. Step 8: Allow the brownies to cool in the pan for at least 10 minutes before cutting into squares.
