Preheat the oven to 350°F. Grease an 8x8 baking pan, then line it with parchment paper. In a small bowl, mix the flaxseed and water. Set aside to let the mixture thicken.
Combine the flour, cocoa powder, sugar, baking powder, and salt in a large mixing bowl, whisking until well combined.
Add in the melted butter, vanilla, soy milk, and thickened flax mixture. Stir the batter until just combined, being careful not to overmix.
Gently fold in the chocolate chips, then pour the batter evenly into the prepared baking pan. Sprinkle some more chocolate chips on top (optional) before baking.
Bake at 350°F for 25-30 minutes, or until a toothpick inserted into the center comes out almost clean.
Let brownies cool in the pan for 10-15 minutes, then transfer them onto a wire cooling rack for another 10-15 minutes before cutting. Happy eating!
Notes
Grease the pan: Rub a little butter in the pan before lining it with parchment paper, which will secure it in place. Once it’s secured, grease the parchment paper with a little more butter so there’s no chance of your brownies sticking.
Cool before cutting: It may be tempting, but don’t cut into the brownies right away. If they don’t set, they will end out like a gooey mess.
Oven temperature: Make sure you have the right oven temperature by purchasing a portable oven thermometer. All ovens vary slightly, so a thermometer helps ensure more accurate and consistent brownie results.
High-quality ingredients: Using quality ingredients results in the best-tasting brownies. From the cocoa powder to the chocolate chips, choose the highest quality ingredients you can afford.
Don’t overmix: Mix your dry and wet ingredients just until you don’t see flour streaks. If you mix too vigorously you’ll end up with dense or dry brownies.
Don’t overcook: Overcooking results in dry, crumbly, and crispy brownies. Take them out just before you think they’re ready. They may look slightly underdone, but they will set as they cool.
