Vegan Fudge Brownies – Gretchen’s Vegan Bakery


You’ve probably heard about the 100 hour fudge brownies challenge 

If you are like me you are wondering why on earth can anyone wait 100 hours for a brownie!
So I decided to get to testing various recipes and my trek began to get to the bottom of this and I found out some very interesting things!

What’s all the hype about?

I mean, seriously I can make the most amazing vegan fudge brownies in just about one hour!

First things first though, I had to veganize the best fudge brownie recipe!

If you watch the video attached to this recipe linked below
You will see the process and my opinions regarding this whole idea.

For those who just don’t have time to sit through a 12 minute video I will give you the low down straight away.

Spoiler alert! I honestly couldn’t tell the difference!

In my opinion there really was not much difference between the brownie batter that sat in the refrigerator for 100 hours before baking
vs. my super easy mix and bake in less than 1 hour fudge brownie recipe!

Have we been duped into believing all the hype that this amazing 100 hour brownie recipe is going to change your life?

Or perhaps vegan brownies are just superior with their magical goodness without making us wait days on end to enjoy the treasure!
But if you want to see for yourself go ahead and make the recipe below just as I did over a span of four days.
Then make it again and then bake them both at the same time.
I’d love to hear your comments if you do try the long version and comparison.

Notes for Success:

This recipe is being baked in a 1/4 sheet pan but can be done in an 8″ x 8″ pan as well

Many people are adverse to using coffee in their recipes; you can leave it out and use water instead
But first understand that coffee brings out the best in chocolate and you will not taste the coffee in the final result

Molasses seems to be an ingredient not readily available to most so if you cannot get it just switch to light brown sugar and increase it by 1 extra tablespoon

Any cocoa powder will be fine for this recipe, read more about cocoa powder here
