I used King Arthur’s Black Cocoa and Dutch Cocoa
in these brownies, which by the way are very moist, yet cake-like and the texture is amazing.
If you’ve never used black cocoa give it try! Black cocoa is a super-dark Dutch-process cocoa. It gives your chocolate treats an intense, deep chocolate color and is ultra-rich in flavor, so you don’t need to use as much.
This rich cocoa will make the darkest chocolate cake or cookies you’ve ever seen.
That’s why these are perfect for Halloween, right?
By the way, besides the deep dark chocolate components, these brownies were made with whole wheat flour, bananas, and peanut butter. So therefore, we are healthy-ish, up until we add the creamy peanut butter frosting, chopped Reese’s Pieces and mini chocolate chip cookies.
Sounds like a well-balanced compromise to me!
Dark chocolate and peanut butter together make me happy!
Bring these to the parties!
Bring these to the office!
Make these for birthdays!
Bring these to the closet?
LOL! I’m a hoarder of chocolate, what can I say? And now it seems peanut butter has always been following suit, but I don’t talk about it as much as I do chocolate. But I have a deep affection for the dreamy duo!
These Vanishing Black Cocoa Brownies will vanish before you know it! Enjoy!

I LOVE the look of these! They sound amazing and that black colour is stunning.I’m only gutted that I can’t get hold of black cocoa powder for the life of me in The Netherlands or even online to ship it here. I’ll just have to look at your brownies whilst I eat my own regular coloured ones trying to taste the darkness :’D
Have you tried Amazon? That’s where I got it or you could try King Arthur Flour. It’s their black cocoa that I used. Thank you so much, I love the color too and it’s gives the chocolate a deeper flavor when you use it. I love it! ๐
My son would just love this thanks a lot for the recipes ๐
You are very welcome Claire! These are super yummy brownies!!
