Preheat the oven to 350°F (175°C).
Grease and line a 9x13-inch baking pan with parchment paper.
In a medium saucepan, melt the butter over low heat.
Remove the saucepan from heat and stir in the sugar.
Add in the eggs one at a time, mixing well after each addition.
Stir in vanilla extract until fully combined.
Sift together the flour, cocoa powder, baking powder, and salt in a separate bowl.
Gradually fold the dry mixture into the wet ingredients until just combined.
Optionally, fold in chocolate chips for added richness.
Pour the batter into the prepared baking pan and smooth the top.
Bake for 25 to 30 minutes, until a toothpick comes out with moist crumbs.
Allow the brownies to cool completely in the pan before slicing.
Cut into squares and enjoy your Touchdown Brownies!
