How to Make a Funfetti Mug Cake

Microwave the batter for 60-90 seconds or until you get a light and fluffy cake. This recipe makes one cake, which you can enjoy by yourself or you can share it with someone special. Top it with a scoop of your favorite vegan ice cream or a dollop of vegan whipped cream.

Notes on Substitutions
  • Omit the sprinkles to make a plain vanilla cake. It’s just as good!
  • You can use any light tasting oil, such as avocado oil or vegetable oil.
  • If you don’t have plain and unsweetened oat milk, you can use any other plant-based milk. Ideally, use a plain and unsweetened plant-based milk as this is what was used to test this recipe.
  • 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!
Suggested Add-Ins:

Serve this cake with a scoop of your favorite vegan ice cream. Vanilla ice cream will be a great 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.

This vegan mug cake is not made to be healthy or nutritious and that’s okay. We don’t need to healthify everything we eat. Vegans and non-vegans all need delicious cake options! I hope you’ll love this one.

Notes

Omit the sprinkles to make a plain vanilla cake. It really tastes just the same!
You can use any other plant milk, such as soy milk or almond milk. I would recommend using plain and unsweetened milk as this is what I used when testing this recipe.
I haven’t tested this cake with other flours, so I can’t guarantee it will work with other options. If you try a different flour, let me know how it turns out in the comments!
You can use your favorite granulated sugar. I tested this recipe with both regular white granulated sugar and turbinado cane sugar. Both worked well.
