These chocolaty, tender brownies use a simple substitution and just a few recipe tweaks. But make sure you follow both the ingredients and directions to the letter for the best results. See the post above for FAQs and tips.
Preheat your oven to 350ºF. Grease an 8×12-inch or 9×13-inch baking pan or line it with parchment paper.
In a small bowl, stir together the ¼ cup water and the egg replacer until the powder is dissolved.
Dump the brownie mix into a large bowl. Add the egg replacer mixture, the remaining ½ cup water, and oil. Whisk or stir until the ingredients are combined.
Scrape the brownie batter into your prepared pan and even it out.
Immediately bake the brownies for 25 to 35 minutes (test after 25 minutes), until a toothpick inserted in the center comes out clean.
Let the brownies cool completely in the pan before cutting into squares.
The brownies will keep in an airtight container at room temperature for a few days, but we prefer to freeze any we won't be eating within a day. These brownies freeze well.
