Double Chocolate Peanut Butter Mug Cookie

Perfect for when you just want one dessert not three dozen, this Double Chocolate Peanut Butter Mug Cookie will satisfy your sweet tooth and not ruin your diet (and the peanut butter is optional!)

{Hahahahaha. I just said peanut butter optional. #wordsineverthoughtiwouldsay}

Hi everyone! You may not know it but I’ve been kiiiiind of ignoring this space for the last two weeks. All my posts through yesterday were scheduled before Christmas. I wish I could say I’ve just been relaxing on the couch for the past two weeks, soaking up books and movies, but alas. I’ve been arm deep in batter and cheesecake and cookies. Such is life…for another month or so. It’ll be worth it in the end.

Anyway. the other day I asked on Facebook  if I should post a mug cookie or a regular cookie recipe today. And overwhelmingly the answer was MUG! And I’m super glad too, because the cookie recipe is fabulous (coming later this week) but this mug cookie is WOW.

It’s a cookie. For one. In a mug.

It’s a chocolate cookie. With mini chocolate chips. And peanut butter. In a mug. Single-serve. For one.

If you’re not like me and don’t have two identical (but for the failed crust on one) cheesecake bars, a batch of donuts, and three dozen cookies on their counter, and you want something sweet but not a whole batch, this recipe is for you.

I adapted an adaption of this chocolate cookie recipe to make this cookie. This is where my nerdy math background (summa cum laude in mathematics, thankyouverymuch, although I laugh when I think about it because I’m so not even close to that level anymore, if I even was) comes in handy. I can convert fractions of cups into tablespoons and teaspoons and divide by 12 or 36 or whatever. It’s actually quite simple…which I know just made about 3/4 of you roll your eyes.

The tricky part is the egg. How do you twelfth an egg? You don’t. You adjust other things so that you can use 1 yolk. It’s just how it is. The beauty of this recipe is that you can make it egg-free by substituting milk or water (1 tablespoon) for the egg yolk. It won’t rise as much or be as rich, but it’ll still be good.

The chocolate and richness of this cookie make it taste like a brownie. A rich fudgy brownie that’s actually a cookie that’s been 36th’d.

The peanut butter is just because I’m…me. Everything is better with peanut butter, especially chocolate and fudgy cookies. I just added a dollop of Super Chunk Skippy Naturals (my favorite brand). You can totally leave it off, or use Nutella or Biscoff or any other nut butter or spread.

It whisks up in a few minutes and cooks in 30 seconds. Perfect when you need chocolate NOW but got rid of it all because it’s January.

It’s almost too easy. I’m sorry?

    Peanut Butter Optional?! No way! I love Skippy Naturals as well…so creamy and smooth without all the added stuff! Girl, I need this…Tonight. And it only takes a few minutes, which means I can totally make that happen! My tastebuds love you. I love you. You win.

      I’ve found the trick is to make the mixture thicker. Whenever my mixture has been too thin it just boils over!

    I totally laughed about the recipe math part… I do that ALL the time! (And it totally helps confused customers on the baking aisles who need to know how many teaspoons are in a tablespoon and how many tablespoons are in a cup.) I ran into the problem of dividing eggs a few years ago when trying to halve a cake recipe with 3 eggs. I started using an egg substitute called Ener-G (very popular in vegan baking!). It’s a shelf-stable powder (lasts for months, if not years!), and 1 1/2 tsp Ener-G + 2 tbsp warm water = 1 egg. Much easier to divide that kind of egg by 12! ;)

      Sweet! I need to find that. I thought about using my husbands egg whites, but figured not everyone would have it on hand. Thanks Amy!

        You’re welcome! Some Safeways have it; others don’t. But I can always find it at Whole Foods and the Nugget (not sure if that chain extends past Sacramento though!). Any vegetarian- or vegan- or health-food oriented store should carry it. Good luck!! :)

    I have to make more mug cookies! I’m so jealous of your quick math skills. I’m always worried when I half a recipe. Not that I’ll get the math wrong, but that I’ll half one ingredient and put the full amount for another!

    I have tried so many times to get a good mug cake, let alone a cookie, and let’s just say, they didn’t work. :) You nailed this one, hit it out of the park – everything about this is perfect! The cookie truly looks like a brownie (you just stole my heart) and I can’t stop thinking about that warm melted peanut butter in the middle. After my microwave failures, this recipe has all of my respect!

    Ok, tried this (out of weight watchers ice cream candy bars:(. BUT, after the holidays trying to cut down on sugar and others. SO, I cut out some of the brown sugar and used applesauce instead of the egg. It was still pretty good. Not very sweet, but didn’t need to be, it was rich enough. Will have to make for DH tomorrow night, his carriage has turned into a pumpkin a little early tonight!

    Hi Dorothy! I made this mug cake because of 2 reasons last night:

    1) I had a dream about it (because I follow your blog) and I had made it in my dreams. So of course it’s in my subconscious I had to give it a try. Lol
    2) Last night I went to a dinner party and for dessert there was a yucky custard-y-pudding-trifle. Ewww I mean that’s just yuck! When I came home I made this mug cookie and I’m so glad I did, it was the perfect size and it was really good. I’m gonna try the coffee cake one too that you posted earlier. thanks

    An way this could be made with an eggbeater equivalent to one egg instead of a real egg?

    • Dorothy Kern replied on January 12th, 2014 at 7:08 pm

      Yes! I think it totally could. I’m not sure what them measurements are, but I’d say 1/2 an egg (however much egg beaters that is). Whites would work too. I wanted to use that, I just didn’t have any! Let me know what amount you use and how it works!

    I’m getting ready to kill my chocolate craving for today with this mug cake. But I have to share something with those of you who have a Whole Foods Market nearby. If you are a PB lover, you MUST TRY the fresh ground honey peanut butter, usually available in their bulk section. I always grind it fresh in the store, although they also have it ready to go as well. It’s something psychological, I guess. haha. I assure you… It.Is.The.Best.EVER!

    • Dorothy Kern replied on March 22nd, 2014 at 2:16 pm

      I LOVE their freshly ground PB! And, if you have a food processor, you can make your own too. Just grind peanuts (and honey, if you like) for several minutes and you have PB!

I don’t own a microwave but I will share these recipes with my readers. My blog is recipes that have been trimmed down for 1-2 servings. http://www.mealsalone.com

      Yes, I’m 99% sure it can! Just use an oven safe dish (ramekin or other similar size). 350°, probably under 10 minutes, watch it after 5!
