Easy Wacky Cupcake Recipe
I am very sure that you heard the word wacky cake before. This type of cake absolutely delicious just like an ordinary chocolate cake. For little bit info just in case some of you did not hear about the wacky cake before, it is a chocolate cake from depression era when food source was limited. It actually turns out into a perfect and famous cake of all times.
My dear friend told me about this cake when I had no clue what to make for my little one’s first birthday five years ago. I was still learning how to substitute dairy for baking at that time. I also wasn’t sure if she had an egg allergy or not.
She had done the allergy test to a specialist when she was few months after her first birthday. So, I mostly guessed what she was allergic to, and stay away from the common allergen. I made several batches of this cake at that time, it turned out the cake was perfectly safe for her, and tasty one for us who love chocolate cake.
The ingredients for the wacky cake are the staple pantry food without egg and dairy. It is so simple to make. Basically, you whip the batter on one bowl only, means less cleaning after.
Based on the wacky cake, I made it into a cupcake with one more special dairy-free frosting. I say it a special one because you definitely can make a healthier alternative for the icing without a heavy load of sugar on it.

This frosting is not loaded with sugar, the sweetness comes naturally from sweet potato, chocolate chip, and maple syrup. If you would like it more sweet taste, you can add any other sweetener or icing sugar half a cup at a time.

I would never have thought to make frosting out of sweet potatoes! How unique! I bet it tastes delicious too!!
Thank you, if you like sweet potato, then it is delicious, I personally love this frosting, as I don’t have to use bags of sugar icing.
I’ve never heard of wacky cake before! What an interesting concept!
Me neither, and it become my favorite chocolate cake now, no need egg and butter to make a delicious cake, it is a bonus for sure!
Thanks for sharing this wonderful recipe. Now I have new ideas to try.
Thank you, there is always new ideas to try!
I love that it only uses one bowl! ? I’m guessing if you really wanted to you could use sweet potato baby food to make it faster.
One bowl recipe is the best! I think sweet potato baby food is more runny consistency, by roasting the sweet potato first make the puree thicker! But you could try it using one!
This actually sounds very delicious! I bet my girls would LOVE to make these! Im going to try it out.
Thank you, yes please, I hope you like it as much as we do!
I like it when I can eliminate sugar from my desserts. Sweet potato is an excellent substitution to it.
I am definitely going to try this.
Thank you, you can always have a sweet treat with no sugar loaded!
I would try this! I’ve made brownies with pureed carrots and spinach and they taste great!
Oh, I love the idea of spinach and carrot on brownies, a great sneaky way for a picky eater, I have to try that one for sure!
The presentation of these cupcakes is adorable. I especially love the cherry on top.
Thank you, everything looks perfect when we put cherry on top, hehe
Looks so yummy! I would never have considered sweet potato for frosting until now 😉
Thank you, you just make a sweet mashed potato, hehe
I’ve never heard of wacky cake! BUT I am making this!! OMG, sweet pot frosting?? Perfection!
Thank you, yea I also had never heard one before, now I regret did not know this cake earlier!
I can’t wait to try this recipe! I recently eliminated dairy from my diet and love looking for alternatives to enjoy favorite treats!
Yes please, oh this wacky cake is absolutely moist and delicious, you won’t miss the chocolate cake that contain dairy after you try this!
When I first saw this post i thought, sweet potato frosting… um, I’ll pass… But after reading through this article and seeing all of your pictures, I take that all back… Those cupcakes look absolutely amazing. I’ll definitely try this recipe in the near future… I’ll keep you updated… Thanks…
Thank you, yup, I still have few people in my house turn their nose off when they hear sweet potato too, but they are missing something good here, haha. Yes please keep me update!
What a great dairy alternative! This is going to the bake soon list. Thank you!
Thank you, yes please, I hope you like it too! Having dairy allergy is challenging for sure!
Sweet potato frosting is a new one for me, but it looks delicious!
Thank you, it is new for me as well, but I love sweet potato on everything, lol
These sound really interesting and delicious, will need to give it a try!
Thank you, yes please, I hope you like it too!
Hmmmm ~ sweet potato frosting. Now THAT sounds unique and interesting. May have to just give this one a try.
Thank you, yes it is, no need a full bag of sugar icing to make a frosting!
Those look delicious! And I love the cherry on top!
Thank you, well, got to use these yummy cherry for some reasons, hehe
Love the idea of sweet potato frosting! I’ve tried avocado frosting, and that was good but still needs some sweetening. I am mostly dairy free, so I generally use coconut milk in my baking.
Love coconut milk on any cooking recipes, I use it a lot for soup too!
These look good! I’ve never made any sweets with sweet potatoes before. Looks yummy and helpful for those with allergens.
Thank you, yes it is, living with food allergy is challenging when it come to a treat, hehe
So interesting! I love sweet potatoes and always trying out new recipes. Will try this!
Thank you, sweet potato always good on any savory or sweet, hope you like it too!
This is wacky! But sounds super intriguing. And your photos make the cupcakes look delicious. I’ll have to try them.
Thank you, as wacky as can be, hehe. But seriously, chocolate cake is so easy this way! I hope you like it too!
These look so yummy!
Thank you!
How exciting to have sweet potato icing. I love it. Love that the elegant cup cakes are dairy free.
Thank you, it is totally possible to have dairy-free cupcake!
Cooking and, especially, baking for allergies is difficult but it sounds like you are slaying it! I’m super intrigued by the frosting!
Thank you, it is quite challenging, especially for substitute some ingredients, the frosting hold up quite nicely!
Ok, so what did your tiny person think of the texture? Mine is picky because of textures rather than flavors. Did it come out smooth and cake like, or more dense?
The cake is soft, chocolatey, and light. Just like a normal chocolate cake. You can even make it fudgy by adding melted chocolate to the batter before baking. She love it a lot, and she always ask me to bake it into a cake, or turn it into muffins, or baked donut.
I’d never heard of wacky cake before today. That’s really neat. I will definitely have to try these at some point. Funny story, I made my dog a birthday cake last year (and by cake I mean meatloaf, haha) and made sweet potato icing for it – just used mashed sweet potato and some coconut oil, she loved it!
Thank you, I had never heard of this cake before either until few years ago when I bake one for my daughter’s birthday. Oh yea, sweet potato is so versatile and healthy for us and pet too!
Our daughter is dairy free too. I can’t wait to try this. We don’t give her a lot of sweets, and sometimes it’s just because she can’t eat it with the dairy. It’ll be so awesome to make her a little treat.
Fingers crossed I have some baking skills though…
It is quite challenging with dairy allergy, because it can be on everything if we get it from store or bakery. Please try it because this cake is so easy and quick to make!
I have to tell you that I read the blog post’s title twice because of the “sweet potato frosting”. Ina, this is such a great idea and something that I can try with my kids who don’t like sweet potatoes.
Hehe, thank you, I know some people especially little kids will think twice when they hear sweet potato. Please try it, hope they like it as much as we do!
Yum! That’s so cool that the frosting has sweet potato in it!
Thank you, yes, so, no need sugar loaded icing for frosting.
OMG..sweet potato frosting!! I can’t wait to try this!! Thank you!!!
Yes please, let me know how it goes, add more sweetener if you prefer sweeter, otherwise it is already sweet and perfect frosting consistency!
