  1. Preheat the oven to 350 degrees F (175 degrees C). Grease an 8 inch square baking dish.
  2. In a large bowl, combine the flour, cocoa, baking powder and salt; set aside. In a separate bowl, stir together the melted butter, sugar, and vanilla. Mix in the eggs. Gradually stir in the dry ingredients just until blended. Fold in chocolate chips and pecans if using. Spread the batter evenly in the prepared pan.
  3. Bake in the preheated oven until the edges start to pull away from the sides of the pan and the top appears dry, 35 to 40 minutes.

I live at 7500 ft and they were great for me! (7/8 cup is 1 cup minus 2 Tbsps)

These were okay. Like another reviewer said, I have had better brownies from a mix. The batter was delicious though.

This was a wonderful brownie, gooey in the middle and crunchy around the edges. I used a 9x13 pan and I am so glad I didn't double the recipe, it was still pretty thick. I used 3/4c pecans and...

These are the best brownies I have ever made - very moist, chewy and "fudgy". I live at 10,500 feet and they turned out great at 38 minutes.

I live in Quito, which is 9895 ft above sea level. Brownies are one of the most difficult treats to make here. But, these passed the test. Not only against the altitude, but with all of my High ...

Oh my goodness I made these the other nite & I live near Boulder, CO and have always had difficulty perfecting the art of baking at high altitudes, however this recipe has converted me for sure!...

I live at 8,228 feet and have all but given up on baking. That being said, I have made these brownies 3 times with rave reviews. It's so nice seeing these come out of the oven without a big cr...

Tried this recipe at about 6500' and were quite pleased with the result. Chewy and fudgy and delicious! Definitely add the chocolate chips.

I made this recipe at 5000', it turned out great! The time was right on. The nuts and chips are an added touch, making the brownies even tastier. I will be making these again.
