Ingredients

  • 1/4 cup white all-purpose flour, spoon and level
  • 2 tablespoons granulated sugar
  • 1/2 teaspoon baking powder
  • 1/8 teaspoon fine grain sea salt
  • 1 tablespoon avocado oil, or other light tasting oil
  • 3 tablespoons oat milk, unsweetened, plain
  • 1 teaspoon vanilla extract
  • 1/2-1 teaspoon vegan sprinkles (optional)
  • Vegan ice cream, for topping

Instructions

  • Add the flour, sugar, baking powder, salt and sprinkles to a medium mug. Stir to combine.
  • Add the oat milk, oil and vanilla to the dry mixture. Stir using a spoon or small whisk until combined. Make sure not to overmix, but mix until smooth.
  • Microwave for 60-90 seconds. The timing will depend on your microwave. Keep an eye on the cake and if it overflows (this shouldn't be an issue), heat it in small intervals.
  • Serve with a scoop of your favorite vegan ice cream if desired.

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.
