Follow these easy steps to create your own batch of Gooey Brownies:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper.
2. Melt Butter: In a saucepan over low heat, melt the butter. Remove it from heat and let it cool slightly.
3. Mix Sugar and Eggs: In a large bowl, combine the melted butter and granulated sugar. Stir until well mixed. Add the eggs one at a time, mixing well after each addition. Then stir in the vanilla extract.
4. Combine Dry Ingredients: In another bowl, sift together the flour, cocoa powder, salt, and baking powder.
5. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
6. Add Chocolate Chips and Nuts: If desired, fold in the chocolate chips and chopped nuts for added texture and flavor.
7. Pour Batter into Pan: Spread the batter evenly in the prepared baking pan.
8. Bake: Place the pan in the preheated oven and bake for 25-30 minutes. A toothpick inserted into the center should come out with moist crumbs, not clean.
9. Cool: Remove the brownies from the oven and let them cool in the pan for about 10-15 minutes before transferring them to a wire rack to cool completely.
10. Cut and Serve: Once cooled, cut into squares and serve.
