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.

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.

For a gluten-free option, you can replace the flour with a 1:1 gluten-free flour mix. I tested the recipe with this flour and it worked well.

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.
