These were absolutely decadent! Neither my husband nor I am vegan, but we strive for health, diversity, and joy in our cooking and eating. These hit each mark. I used all whole wheat pastry flour and we don't use margarine so I used canola oil. I added the walnuts and additional chopped, very dark, vegan chocolate. I baked at 350 for 30 minutes because we like gooey, chewy brownies. The big, melted chunks of chocolate made the overall product a little structurally weak when removed from the pan, but no one really cared. These oozed melted dark chocolate, were moist and chewy, and had a wonderfully cookie-like crust. This is my new go to brownie recipe. Thanks!
