I originally shared this Microwave Sweet Potato Mug Cake back in September of 2015 and I still make it regularly. Have you ever tried a microwave mug cake? It’s basically a nice, warm dessert that’s ready in two minutes and doesn’t require an oven. Just mix a few ingredients, pour into a coffee mug or mason jar and pop it in the microwave.
This is my favorite way to make dessert after a long day when I don’t have much energy left. However, I’ve also been loving this as a snack lately! I leave out the maple syrup and just add a handful of chocolate chips. This recipe is essentially a small batch of my Sweet Potato Banana Bites cooked in the microwave instead of the oven, so you could also add some mashed banana instead of maple syrup for sweetness if you want!
This Microwave Sweet Potato Mug Cake recipes makes the perfect amount to split between two mugs, mason jars or ramekins and share with a loved one. Topping it with ice cream is pretty much a must in my book. To make this on the fly, you’ll first need to cook your sweet potato. I just poke a few holes in mine and then microwave for five minutes. To make this even easier, I cook a sweet potato on the weekend and save it in the fridge so I have some mashed sweet potato ready and waiting whenever I want one of these!
Here’s how you make it:Print

See how easy it is? Especially if you have the sweet potato already prepped, this treat comes together in a flash! You could also try this recipe with pumpkin or roasted squash.
Life’s short. Eat dessert. Like cake. But when you don’t have time to make a full cake, make this!

Love all mug cakes, but I’ve never made one with sweet potato before. Great idea, considering I have two sweet potatoes sitting on my table that I need to use.

This sounds so good!! The only problem…we don’t have a microwave! HA! Honestly, I love not having one, but wish we did for little mug cakes like this!

I recently received a mug cookbook and tried one of the recipes w/ great success. I’ll be adding your recipe to my must-try list! Looks delish.
Erica D House says
This looks so good! I’ve been all about mug cakes lately, but mine have about 10x the sugar (and calories) as this one. I’ll definitely be trying yours out soon!
Shashi at RunninSrilankan says
There’s absolutely no flour of any kind in these! Wow!!! Love this recipe Lindsay – thanks so much!
This looks great! I’m wondering if it would work with pumpkin too as I have more than I can deal with at home at the moment! I’ll let you know if I try it.

Wow this sounds amazing and looks so pretty! My husband and youngest are big sweet potato fans, I’m going to have to whip some up for them!
Sam @ PancakeWarriors says
I’m all about the return of the mug cake!! I love that you used sweet potatoes, we always have extra from meal prep that I like to make into sweet dishes! Can’t wait to try this one 😉 And yes to the ice cream!!
Sweet potatoes are the best.. they’re so versatile!! This looks like a yummy one! Also.. your mugcake looks perfect.. when I make them they always taste delish.. but look kinda like dog food- LOL
Call me crazy, but I have yet to make a mug cake. This will definitely be the first one I try!
Erin @ Erin's Inside Job says
This looks so good and it perfect timing for fall. Also, prob quite a bit healthier than the 60 sec microwave choc chip cookie I used to make all the time 🙂
Erin @ Her Heartland Soul says
Oh wow this sounds fabulous! Thanks for sharing!
Ashley @ A Lady Goes West says
Well I’ve got to try this one. I eat sweet potatoes for nearly every meal, but never for dessert. Thanks for the simple recipe! 🙂 And good luck finishing up that to-do list!
Jenn - a traveling Wife says
This looks amazing. I would have never thought to make a sweet potato mug cake – genius!
How cute are these! I love these mug recipes! I am glad to see a mug recipe that you can feel good about, too!
[email protected] says
I love this, but let’s be honest, I would probably make it with full intentions to share, then eat them both myself. Chocolate chips included 🙂
Good luck on your to-do lists.

Frugal Foodie Frank says
This looks absolutely delicious! I bet an impromptu cream cheese frosting would take it over the top 🙂
Kalee @ The Crowded Table says
I love mug cakes, and I’ve been wanting to try a version for fall…………yours looks delicious! 🙂
Erin @ The Spiffy Cookie says
It’s been far too long since I’ve made a mug cake!
I’m lickin’ my chops thinking about it. I’d have to eliminate the egg right now, do you think it’d still be enjoyable?
you might want to try a spin on this one bc it doesn’t use an egg: https://www.theleangreenbean.com/microwave-sweet-potato-muffin/
Lauren Gaskill | Making Life Sweet says
This is such a simple and delicious idea! Can’t wait to try it!
Gluten free, sweet, delicious!!!! A keeper!
I’m vegan so I just used egg replacer (flaxseed + water) and it turned out amazing! I mixed all the ingredients and realised there was no flour or milk and put it in the microwave wondering and my mind was blown! Thanks for the recipe it’s in my favourites now 🙂
