Follow these simple steps to bake your way to brownie bliss:

1. Preheat your oven to 350°F (175°C). Grease a 9-inch pie pan with butter or non-stick spray.
2. In a large mixing bowl, whisk together the melted butter, granulated sugar, brown sugar, and vanilla extract until smooth.
3. Add the eggs one at a time, mixing well after each addition. This step is crucial for achieving that gooey texture.
4. In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt.
5. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid overmixing.
6. Fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.
7. Pour the batter into the prepared pie pan, spreading it evenly with a spatula.
8. Bake in the preheated oven for 30-35 minutes, or until the edges are set but the center remains slightly soft.
9. Remove from the oven and let the pie cool slightly before serving. This will help the gooey center set a bit more.

One of my favorite tips? Save a handful of chocolate chips to sprinkle on top of the pie right after it comes out of the oven. They melt beautifully and add an extra layer of chocolatey goodness.
