Funfetti Mug Cake Ingredient Notes:
- Flour: This recipe is made with all-purpose white flour. You can also make it with a 1:1 gluten-free flour mix, such as this one. I haven’t tried making this recipe with other flours. If you try any other flours, let me know how it turns out in the comments!
- Sugar: I tried this recipe with Turbinado cane sugar and regular white sugar. Use what you have on hand.
- Baking powder and salt: Baking powder to help the cake rise and salt to help balance the sweetness and enhance the flavors.
- Oil: Use a light-tasting oil. I love using avocado oil in this recipe.
- Oat Milk: This recipe was tested using plain, unsweetened oat milk. You can use any plant-based milk, preferably a plain, unsweetened milk.
- Vanilla: For flavor.
- Sprinkles: Feel free to omit the sprinkles to make a plain vanilla cake. It’s just as good!
Suggested Add-Ins:
Serve this cake with a scoop of your favorite vegan ice cream. Vanilla ice cream is a delicious classic option, but you can try other flavors.
Not an ice cream lover? You can top it with vegan whipped cream or coconut whipped cream instead. It’s also good plain, but toppings do take it to the next level.

ok WOW! This is soooo delicious!! I didn’t have the sprinkles so I omitted them. I think next time I’ll try some blueberries in it! Thanks for sharing

I’m so happy you liked it!! Blueberries would be good too. Thank you for sharing your feedback! 🙂

Update- I was curious if almond flour would work and I was very unsuccessful. At least not Bobs Red Mill almond flour. I’ll stick to using normal flour LOL!!

Hi Danielle, thank you for the update! My guess is that any almond flour won’t work as it works differently than regular flour. I’ll update the post when I try other flour options, but I’m thinking that whole wheat and spelt might work. But regular flour is always a good option. 🙂

I used coconut oil and didn’t have any sprinkles, it came out moist and delicious, thank you!

I was watching Grey’s anatomy and scrolling Instagram when I saw this recipe. Popped over here and realized it would take me 5 minutes. Paused Grey’s and made this! I subbed Bobs Red Mill GF one to one flour and it worked beautifully! SO easy and SO delicious! Thanks for a quick and easy treat to enjoy with my evening TV show 🙂
