Black Bean Brownie Mug Cake

I don’t understand how anyone could dislike a mug cake.  They are super easy and fast and satisfy any dessert cravings in less than five minutes.

Well, today I’m going to shock the socks off your mug cake lovin’ shoes.

You can make a mug cake out of beans.  And it can taste like a fudgy brownie, not even kidding.  It is possible to take beans, whole wheat flour, honey, and cocoa powder and make a dairy free whole wheat mug brownie.

(don’t think I’m not seeing your bare feet)

Now, I’m not going to lie, I like some whacky foods.  I don’t always share them with you, because well, they are kind of out there.  But when my mom and brother (lava cake lovers to the extreme) ate this, thinking it was a lava cake and were only disappointed because it tasted like a fudge brownie instead of a lava cake, you know this is for reals good.  No, this is not a lava cake.  It is a mug brownie.  Oh, I never told them it was made from beans, not even after we finished licking the ramekins (because melted chocolate chips and fudge brownie crumbs are really good!)

Guys, this has a whopping 16 grams of protein per serving.  16 grams!  You have to try this.  Seriously.

My next person on my list to thank is Zainab, from Blahnik Baker.  Ironically, it was her cakes that first caught my attention.  She makes crazy amazing cakes.  But she is an even better blogger friend than a baker.  When she first emailed me, just for fun, she didn’t probably anticipate the floods of emails she would receive from me asking her a million and one questions.  And she answered every.single.question I asked about blogging.  And guys, this wasn’t just one email.  This was months and months of emails!  She guided me through choosing hosts and frameworks and themes and advertising.  Actually, she is still doing that!  She was the first blogger I could ask for solid numbers, like stats and ads and prices.  I can’t tell you how many things she helped me with because it would take several posts – all I can say, is that without her, I wouldn’t be on WordPress.  Period.  And I wouldn’t enjoy blogging like I do.  It is the people behind the blogging that make it worth it.  She always responded quickly and satisfied my curiosity about whether or not WP was worth it, or if transferring it on my own was possible, or if I could make money blogging.  She was open and honest, encouraging and personable, and her blog is a joy to follow.  If you haven’t already, check out her blog.  Just don’t read this post – don’t say  I didn’t warn you.

    Natalie and I just tried them (and for once in our life we didn’t make any substitutions) and they turned out great! The hardest part was waiting for them to cool… we set the timer for one minute and stared at them longingly. :) They were velvety and chocolaty and totally delicious. :) Thumbs up!

    And no need for thanks dear. I was very happy to help at every stage. I loved emailing back and forth and I learned a lot myself. I’m so glad the theme is now installed. I love the look very much :)

      I completely agree! Layered cakes always make me go “ooh” and “ahh!” but I never can commit the time and energy to them (aka I’m a lazy baker … and dish washer 😉

    I’m not gonna lie, I get really scared and apprehensive when super-fattening traditional ingredients are replaced with things like beans, zucchini, etc. But these little cakes look SO good and so easy that I might just have to give them a try!

      I agree, sometimes I’m like, yep, too good to be true! But not in this case :) Thanks for taking the time to comment!

    • maryfrances says

      I’ve always wanted to try your black bean brownies – now that I know beans and choc can be friends, I can’t wait! Thanks Dorothy!

    I love that you put black beans in these and your family was none the wiser! It looks very fudgy and delicious! I love mug cake but it’s been too long since I made one.

      Thanks so much! Mug cakes are so fun and I always appreciate it when they are actually healthy!

    • maryfrances says

      Hi Michelle! Sorry I have taken so long to respond – I have never worked with stevia, so I’m not sure. As for the egg whites, the yolk provides the fat to make it fudgy, but I don’t know if egg whites would work. Let me know what you think if you give it a go! Thanks for stopping by!

      Hi Mirjam! Thanks so much for reporting back – I’m so glad you liked it! It is still one of my favorite recipes on the site. :) Have a wonderful day and thank you again!

    This is awesome. I only had 1/2 cup beans leftover from dinner last night so I couldn’t make a batch of black bean brownies. I need snacks with protein and although this recipe is a bit high in carbohydrates for me for a snack/dessert, the fact that each serving has protein of 1/4 cup beans, I ate a smaller dinner tonight so I could try it. I’m so glad I did. This will be a great occasional treat.

    • maryfrances says

      Thank so much for taking the time to comment Rachel! I so appreciate feedback and I’m thrilled you enjoyed this! It is still one of my all time favorite recipes. Hope you’re having an amazing (chocolate filled :) ) week!
