How to Prepare Fresh Sweet Potatoes

I cooked my fresh sweet potatoes by peeling, chopping and microwaving them in some water. After they were fork tender, I drained the water and mashed. Feel free to try canned sweet potato for this recipe.

How to Make Sweet Potato Cupcakes

For full recipe details, including ingredients and measurements needed, see the printable recipe card down below. Here is step by step what you can expect when making these cupcakes:

sweet potato cupcake ingredients

Preheat Oven + Prep Muffin Tin

Preheat oven to 350° F. Line a muffin tin with 12 cupcake liners and set aside.

muffin tin with paper liners

Combine Sugars + Wet Ingredients

In a large mixing bowl, using a stand mixer or an electric hand mixer, cream coconut oil (or unsalted butter) with both brown and granulated sugars. Stir in egg, egg yolk, vanilla extract and sweet potato. Scrape sides and whip until wet mixture becomes light and fluffy. 

Combine Dry Ingredients

In a separate bowl, stir the dry ingredients (all-purpose flour, baking soda, baking powder, salt, cinnamon and nutmeg) together using a fork or whisk.

Combine Wet + Dry Mixtures

With the mixer on low, alternate mixing in dry ingredients and the milk, into the bowl with the wet ingredients, starting and ending with dry flour mixture.

Once ingredients are all incorporated, mix the batter together by hand to ensure everything is mixed evenly. 

Bake + Allow to Cool

Spoon into prepared muffin tin (filling about 2/3 full) and place into hot oven. Reduce temperature to 325° F and bake 18-22 minutes or until toothpick comes out clean after being inserted. Set aside to cool.

Make the Frosting

Place brown sugar, granulated sugar and water into a small pot. Stir to moisten sugar and place over medium high heat on the stovetop. 

Whip Egg White

In a large bowl, whip egg white and cream of tartar until stiff peaks form. 

whipped egg whites

Combine Hot Sugar Mixture + Whipped Egg White

Once the sugar dissolves in water and starts to bubble (not too violently), set a timer for 1 minute. After the 1 minute timer goes off, remove from heat and stir in marshmallows. Once those have melted, slowly pour the hot sugar mixture into the egg whites while whipping with a hand mixer on medium speed. Continue whipping for 3-5 minutes or until frosting becomes very thick and holds its shape. 

Stir in Vanilla Extract + Scoop Frosting into Piping Bag

Stir in vanilla extract. Immediately (no time to dilly dally with this frosting) scoop frosting into a piping bag and frost all cupcakes. Top with toasted chopped pecans, if desired.

Storing + Make Ahead Directions

Cupcakes should be cooled to room temperature before either frosting or storing. Store in an airtight container with good fitting lid and into the fridge. They will stay fresh for a day or two, but are best enjoyed right away.

Make Ahead – These can easily be made a day before you want to serve them. Once they are frosted, they should be stored in the fridge because of the egg whites used in the frosting.

Freezing – The tender Sweet Potato Cupcakes can be frozen to store for a longer period of time. I would suggest freezing them unfrosted if you can. Then, once you’re ready to pull them out and use, allow them to defrost before frosting.

FAQ + Baking Tips for Sweet Potato Cupcakes

How many cupcakes does this recipe make?

This recipe makes 12 cupcakes.

How do I easily cook a sweet potato? Can I use canned from the grocery store instead?

I cooked my fresh sweet potatoes by peeling, chopping and microwaving them in some water. After they were fork tender, I drained the water and mashed. Feel free to try canned sweet potato puree for this recipe.

Can I substitute pumpkin or butternut squash puree instead?

Yes, ultimately you can. Of course, these wouldn’t be sweet potato cupcakes anymore. 🙂

Do I have to peel the sweet potato for this recipe?

While peeling sweet potatoes for baking is considered optional, you do need to peel a sweet potato when using for cupcakes.

Can I use a different frosting on these cupcakes?

Of course! I would say a Cream Cheese Frosting would work great if you don’t like the taste of marshmallow.

    Wow – these cupcakes are amazing!!! thank you for the recipe. I couldn’t quite get the frosting to turn out right (probably didn’t beat it long enough) but the flavors can’t be beat. I shared the results with some friends and they also were very impressed!

    If I make these a day in advance, is the icing going to break down and be a soggy mess? I’ve had that experiance before when I made other icing with egg whites.

On top of the traditional chocolate and vanilla, they can also be made from ingredients that are more suited to the dinner table than the dessert one — like sweet potatoes, for example.

    I’m making these tonight but am wondering if I could substitute all purpose flour for the whole wheat pastry flour? Not sure if that would effect the texture of the cupcake though?? Any advice would be great!

    My 2 year old and I made these yesterday, and they are awesome!!! Thanks for the great recipe. I am not normally a fan of frosting, but I definitely licked the bowl clean after making these! 🙂

  15. christina @ ovenadventures

    this frosting sounds ridiculous, in a crazy going to eat the entire bowl with my spatula kinda way.

    love these, lady! i am a HUGE fan of baking with sweet potato, or any root vegetable for that matter! also way into whole wheat pastry flour–well, any flours, really. i have an obscene amount of flours in my kitchen, i think it might be an obsession.

    these look absolutely scrumptious, and i think you are such a darling mom! that sweet kid of yours certainly learned well from her mama 😉

  17. Katie

    Sounds great! I love the fact that you ran out of butter and white flour and used healthier alternatives:) Beautiful photos too.

  18. muffinka

    Hi!
    I’m ravishing your frosting recipe. My question is how much is cup?
    It’s like 125ml or 250ml?
    It’s very important for me, because I want to do this frosting, but i don’t have brown sugar, can I use another?

    Cheers!

  19. what katie's baking

    i bet using coconut oil was actually better!! i’m in love with sweet potatoes. this is an amazing recipe!

  20. Krissy's Creations

    You are a wonderful Mom! Only you would bake cupcakes and celebrate a fake birthday for your daughter. And so creative of you working around all of your missed ingredients!

  21. akb

    Can you make this without the whole wheat pastry flour? I have all the other ingredients on hand and would love to skip a trip to the store…

      1. Kristal Jordan

        Since I plan to use all purpose flour do I just use the same measurements you have listed for the white whole wheat flour (2/3 cup) in place of that with my all purpose flour? Just double checking.

  22. Sally @ Spontaneous Hausfrau

    I TOTALLY need one of those pourer-cover thingies. I’m constantly making a mess and getting flour all over the place. Anyway, these cupcakes look so pretty and tasty, especially that frosting!

  23. baker in disguise

    Woww.. its really amazing on how you photograph each and every stage!! and these look amazing.. sweet potato.. who would have thought?!!

  24. Chung-Ah | Damn Delicious

    It’s amazing how you run out of the essentials yet you have so much backup! Now that’s a true baker.

    These cupcakes look great. And your daughter is freaking adorable.

    Also, way to be the best mom ever and let your daughter have another birthday. :):)

  26. Kathryn

    This is such a cute post, I love how you went along with your daughter and made cupcakes for her. I’m pretty sure you are the number one mom in the world right now!

    Also, I’m thinking about replacing my pillow with brown sugar marshmallow frosting. It will be sticky but worth it.

  27. Cookbook Queen

    Love that you used coconut oil!! I have some in the cupboard that I’ve yet to use on ANYTHING.

    That frosting looks like a dream. Yummy!!

      My kids won’t stop eating them! The cupcakes are moist and delicious. I made them to go with tomorrow’s Christmas treats. Only critique is I wish Sam exact measurement was provided for the cream of tartar.

  28. Megan Pence

    I’m so in heart. And if the baby wants to celebrate her birthday a month late or multiple times – it means more cupcakes. And more cupcakes, is Never unfortunate. 🙂

  29. Rachel @ The Avid Appetite

    Love that you worked with what you had. Sometimes that produces the best result! Also crushing on your idea to use sweet potatoes! Yum!

  30. Daisy@Nevertoosweet

    These look fantastic 🙂 it’s great how you were able to immediately change to using coconut butter instead ~ very smart and yummy too 😀 These look so wonderful to me! I love sweet potato but have never had it in a cupcake hehe

    Thanks for sharing!

  31. Erin

    Haha I love how your baking adventures are as problematic as mine. I play it off as being creative by using different ingredients, but sometimes it is out of necessity because I failed at making sure I had all the ingredients beforehand. But look at the amazing results you got! Yum yum yum.

  32. Miss @ Miss in the Kitchen

    Those cupcakes look so good right now! I would be eating them for breakfast! Love, love that frosting!
