VEGAN CHOCOLATE MUG CAKE

Whether you are making this easy and quick Vegan Chocolate Mug Cake for dessert or these Vegan Chocolate Crepes for breakfast, you are going to be more than satisfied. If you are wondering “what is a mug cake?“, then you are in for a real treat! You simply cook a small cake in a mug in the microwave, it’s that easy. And this vegan gluten-free chocolate mug cake I can confidently say is the best one I’ve ever tasted. Bonus that it is gluten-free and oil-free. This isn’t my first ever mug cake recipe though, I have a Vegan Toffee Mug Cake that you should probably make stat.

I’ve probably tasted and tested 10 chocolate mug cakes over the past couple of years. They were all either too dry or simply not enough chocolate flavor. I love really rich chocolate desserts. This mug cake is incredibly moist, but not dense. It has the perfect cake texture and is so decadent and rich.

If you are looking for a healthier low-fat option, make this one!

INGREDIENTS NEEDED

First, you will need to gather these 8 ingredients (+salt):

  • Superfine blanched almond flour: Since almond flour is high fat, it provides the moisture to the mug cake and replaces any oil or butter that would typically be used. So, it is oil-free, but incredibly rich and decadent.
  • Superfine oat flour: I use Bob’s Red Mill.
  • Tapioca starch or cornstarch: This helps to bind the cake, since eggs are normally used in mug cakes, this replaces eggs perfectly and gives the mug cake structure.
  • Unsweetened cocoa powder
  • Baking powder
  • Pure maple syrup
  • Vanilla extract
  • Dairy-free semi-sweet chocolate chips: I use the Enjoy Life brand.

HOW TO MAKE A VEGAN CHOCOLATE MUG CAKE

Step 1: To a small bowl, combine the almond flour, oat flour, starch, cocoa powder, baking powder and salt and whisk very well, making sure to break up any lumps. If your cocoa is lumpy, sift it, otherwise it will not cook through well. Add ONLY 1 tablespoon of the chocolate chips.

Step 2: Add the water, syrup and vanilla and stir well until the batter is completely smooth. The batter is not overly sweet, so this allows for a rich chocolate flavor to come through and also the sweetness from the chocolate chips gives the perfect touch of sweetness.

Step 3: Pour the batter into an 8 oz mug. Top the remaining 1/2 tablespoon of chocolate chips sprinkled on top. This can be spread after cooking to give a somewhat frosting effect, if desired.

Step 4: Place in the microwave and cook for 1 min 30 seconds. (full directions below)

CAN YOU MAKE A MICROWAVE MUG CAKE IN AN OVEN?

Why yes you can! I’m good to y’all, so since many people may not have a microwave, or prefer not to use one, I tested this vegan microwave cake it in the oven, too. Simply pour the batter into 2 parchment paper muffin liners inside a muffin pan and bake for 20-22 minutes. Once the toothpick comes out basically clean (a few crumbs are ok, not wet batter), it is done. Cool for 15 minutes before eating.

Both versions, whether in the microwave or oven, are equally delicious! This vegan chocolate mug cake is everything a mug cake should be. It is cakey, like truly a cake texture, meaning, light and fluffy. Yet it is decadent, moist and super rich in chocolate flavor! With melty chocolate chips inside, you can’t beat it!

Yields 1 mug cake

Ingredients

  • 4 tablespoons (28g) superfine blanched almond flour (I used Bob's Red Mill labeled "superfine")
  • 2 tablespoons (16g) fine oat flour*
  • 1/2 tablespoon (4g) tapioca starch (or cornstarch)
  • 2 tablespoons (12g) unsweetened natural cocoa powder
  • 1/4 teaspoon baking powder
  • 1/8 teaspoon fine salt
  • 2 tablespoons (30g) water
  • 2 tablespoons (40g) pure maple syrup
  • 1/4 teaspoon vanilla extract
  • 1 1/2 tablespoons (23g) dairy-free semi-sweet chocolate chips, divided
  • I use this scale.

Instructions
 

  • To a bowl, combine the almond flour, oat flour, starch, cocoa powder, baking powder and salt and whisk very well, making sure to break up any lumps. If your cocoa is lumpy, sift it, otherwise it will not cook through well. Add ONLY 1 tablespoon of the chocolate chips. OVEN DIRECTIONS in step 6.
  • Add the water, syrup and vanilla and stir well until the batter is completely smooth. The batter is not overly sweet, so this allows for a rich chocolate flavor to come through and also the sweetness from the chocolate chips gives the perfect touch of sweetness.
  • Pour the batter into an 8 oz mug. Top the remaining 1/2 tablespoon of chocolate chips sprinkled on top. This can be spread after cooking to give a somewhat frosting effect, if desired.
  • Place in the microwave and cook for 1 min 30 seconds. This was the perfect time for my microwave (full power) to cook it through to the perfect cake texture but not overcook it or make it dry. Obviously, all microwaves will vary. You will know it's done when the top of the mug cake has a cooked look and not still wet batter if you touch it. It should JUST be cooked on top (refer to the look of the cake in the photo).
  • Set your timer for 4 minutes to cool before eating. The cake will be way too hot to eat immediately and this allows the interior to finish cooking a bit. Depending on your microwave, you may need to alter the time to get it cooked to your liking. Enjoy!
  • To make this in the oven, preheat the oven to 350°F (177°C) and line a muffin pan with 2 parchment paper muffin liners. Follow the same batter instructions and divide the batter evenly and top each with the remaining 1/2 tablespoon chocolate chips. Bake for 20-22 minutes until a toothpick comes out basically clean (a few crumbs are ok, not wet batter). Cool for 15 minutes before eating so they finish cooking.

Notes

  • Make sure to use certified gluten-free oat flour if needed. I use Bob's Red Mill.
  • Nutrition based on 1 mug, however this mug is the equivalent of 2 large muffins. I actually split this with my daughter to be 2 servings or save half for the next day.

      Hi Deborah! Thank you so much! No, it needs to be the almond flour blend above, as since it’s oil-free, that blend is what makes the cake so moist. There are lots of mug cake recipes online that use regular flour if that’s what you want, they are just not oil-free and likely made with white sugar. Just depends on what you’re after 🙂

    Hello Brandi

    What a beauty this cake is! Can I make my own oat flour at home using steel cut oats ?? And if I wanted to double or triple the number of cupcakes in the oven – do I just double or triple the ingredients as is ??

    Thanks

      Hi Lavanya! Thank you! I’m not too sure how fine you can get steel cut oats?? It needs to be totally smooth and fine, like regular all-purpose flour, otherwise the texture will be compromised and your cake more dense. If you can get it really fine, then try it out. Yes, just double or triple the ingredients and definitely use a scale so it all turns out correctly! 🙂

    Hi Brandi,

    This sounds so good.

    I can blitz some rolled oats to get some flour but I’m not sure it will be as fine as the commercial brand you used. Could it be possible to sub with rice (brown? white?) or spelt flour do you think?

    Reply
    • brandi.doming@yahoo.com

      March 19, 2019 at 4:16 pm

      Hi Sandy, I wouldn’t sub with rice flour here, not too sure how that would work, but I think it would make it grainy and dry. The oat flour works amazing here. If you have a Vitamix, you can get them pretty fine. You could also try spelt flour, it is the closest to oat flour, although it may cook slightly faster, not sure.

      Hi Ann Marie, yes, I just calculated it and even though it’s one mug, I do not eat the whole thing in 1 serving, but split it in 2 or share with my daughter. Because, technically, it makes the amount for 2 regular sized muffins, to give you an idea. The calories are 494, or 247 if you per muffin.

    This was wonderful, Brandi. I had given up on mug cakes because the couple of recipes I tried were just a gooey mess and nothing I would consider to be cake—apologies to those who like goo, but I personally prefer cake!), but the texture and flavor were perfect (this came as no surprise–perfection is what always comes with your recipes). So easy to make. This was the fourth thing of yours we made yesterday. Dinner was the potatoes and lentils with BBQ sauce from your cookbook (so delicious!), accompanied by salad with your ranch dressing. Then we shared the mug cake, with one of your chocolate chip crystallized ginger cookies. Yesterday was truly Brandi day and our taste buds are so grateful to you!

      Haha, you cracked me up with “apologies to those who like goo”! I totally know what you mean, too, which is why testing this recipe so many times was so important to me. They’ve either been goo, like you said, mushy/dense OR just DRY as a bone, so getting a moist, fluffy cake in a minute 30 in the microwave was the highlight of the month for me, haha! And I’m so super honored you had a vegan 8 day!! Adding the ginger cookie to this mug cake sounds So amazing Ellen, I totally have to try that!!

    This chocolatey mug cake REALLY hit the spot tonight! It was super easy to make and the perfect dessert when you don’t have time to make dessert! The really funny thing is I had all ny various flours out and accidentally used brown rice flour instead of almond flour, which should have never worked because it needs the fat from the almonds. However, my husband absolutely loved it! It was dense but not gooey. I made it right the second time and noted that it was much lighter and fluffier, but both versions were delicious. Thanks for this scrumptious treat, Brandi!

      Hi Shanna, oops I answered you regarding the wrong recipe earlier, sorry about that. For this mug cake, you can try it doing half the amount of oat flour with potato starch, so 1 tbsp. I have not tested it personally, so I can’t vouch for the results, but that is what I would try. Not sure if the cooking time will be the same. Just look for the dry look on top as in the photos.

    Since I saw this recipe on my email inbox, I was dying to try it, but here were I live in Brazil it is not easy to get maple syrup (and it is too expensive when I can find it). So finally, I couldn’t wait anymore and decided to replace the maple syrup with a homemade sugar syrup. I made it this morning and, although the batter was too thick (almost like a bread dough), it was delicious. Do you think the batter being so thick was because of the sugar syrup?

    Reply
    • brandi.doming@yahoo.com

      April 7, 2019 at 6:35 pm

      Yes, definitely, since you changed a liquid ingredient, that affects the batter consistency. Maple syrup is pretty runny, so that would be why. The batter isn’t running but it’s smooth and pourable.

    Loved it. This is the solution for the instant your brian snaps “I want cake. Now”.
    Tried it out yesterday with my mom, as she has a microwave and I don’t (and I don’t really want to use the oven for just 1 small cake… and if you want something fast, the oven isn’t the best option anyway).
    The only thing I had to adjust was water, which I doubled, because the original mix just simply dry, like I could work it with my hands (like a nuts’ base for a pie, or like the mix to make balls). With double the water and 1:30 in my mom’s microwave boom, the magic was done. It reminded me instantly of the double chocolate muffins (https://thevegan8.com/2013/12/06/double-chocolate-muffins/), which we make pretty often and upon comparison I saw they’re almost the same, so basically, I’ve now discovered that there’s no need to wait and no need to make big batches to get a double chocolate muffin. THIS IS EPIC!!! No need to bake and eat 12 cupcakes in a day, woohoo! Thank you a million for this recipe. I might just be visiting mom and her microwave more often (and I already do visit very often!).

    I’d never had a mug cake. Now I don’t think I’ll make any other kind of chocolate cake again. This was DELICIOUS, and I’m convinced no other mug cake could ever measure up. I made it exactly as you wrote the recipe, it turned out perfectly, and even my husband was impressed. (I almost ate the batter though, it was sooo good.) Perfect proportions for a chocolate cake craving, and instant gratification! Plus these ingredients all are staples in my house.

    Come December I think I’ll try mini marshmallows in the mug cake and see if that doesn’t make the perfect kind of around-the-fire-at-Christmas treat!

    Is there a substitute recommended for the oat flour…my little one has an oat allergy, but we just recently found out about the wheat and egg allergy this week.

      You can try brown rice flour but I can’t guarantee the results. It may be a bit grainier.

        I just made this mug cake and WOW it’s hands down the best I’ve ever had, plus it ticks all the boxes of vegan/GF/refined sugar free! I swapped the oat flour for rice flour, and skipped the corn starch and choc chips (didn’t have either) and it still turned out really amazing! Thank you!

    I do crossfit & typically looking for ways to add in more protein. Could I substitute vital wheat gluten for one of the flours or cornstarch in this recipe if I’m not concerned if its GF?

      Hi Jennifer! I would definitely not add or swap a flour with wheat gluten to this. It will ruin the recipe and make it excessively hard and chewy. Gluten isn’t really something that can be swapped for flours in baking recipes because it will completely change the texture of everything. If you want to use wheat gluten, I’d maybe try googling recipes/baked goods that call for it?

    This tastes AMAZING! I happily made it last night as I had all of the ingredients already on hand (except chocolate chips, which would’ve taken it to the next level for sure). The texture is super soft and light. Perfectly delicious dessert without the added guilt! 10/10

    I got rid of my microwave! Do you have a suggestion for doing this in an air fryer perhaps? I have the Vegan Foodi – instapot + air fryer combined – the best!

      Hi Susie, I included oven directions on the recipe card! I have no idea about using an air fryer.

    I didn’t see any notes explaining the nut-free version. Am I missing it somewhere?

    Yumm… I made 3 of them in the microwave for dessert (one at a time). I didn’t have oat flour but blended up some oats with my immersion blender real quick before I started. This recipe is A+++!!!

    So good! I can’t have oat flour, so I subbed cassava flour, added an extra tablespoon of water and it was perfect! Thanks for the great recipe!
