Preheat oven to 350 degrees F (175 degrees C).

Melt butter completely.

In a large bowl, combine flour, baking powder, and salt.

Add golden brown sugar to the dry ingredients and mix well.

Add eggs and melted butter to the mixture.

Mix all ingredients until smooth and well combined.

Stir in chopped pecans.

Pour batter into a 9x11 inch baking pan.

Spread the batter evenly across the pan.

Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.

Avoid overbaking to keep the brownies moist.

Remove from oven and run a knife around the edges of the pan to loosen the brownies.

Let the brownies cool completely before cutting into squares.

Serve and enjoy!
