FAQs
Can I use self-rising flour instead of all-purpose?
Yes, omit the baking powder and salt if using self-rising flour.
What if I don’t have powdered sugar for the glaze?
You can make a simple glaze with granulated sugar and a little milk, though it will have a different texture.
Can I double the recipe?
Yes, but use a larger mug or bowl to prevent overflow, and microwave in intervals to ensure even cooking.
Is it supposed to be soft and fluffy?
Yes, the texture is similar to a cake-donut hybrid—soft, fluffy, and slightly dense.
Can I add mix-ins like chocolate chips?
Absolutely! Stir in a tablespoon of mini chocolate chips, crushed nuts, or sprinkles before microwaving.
Can I make this without butter?
Yes, you can substitute melted coconut oil or a neutral vegetable oil.
Can I use plant-based milk?
Yes, almond, soy, or oat milk all work well in this recipe.
How can I make it less sweet?
Reduce the sugar in the cake by half and use a lighter glaze or no glaze at all.
Can I bake it in the oven?
Yes, bake in a small ramekin at 350°F (175°C) for about 12–15 minutes, or until set.
Is the glaze necessary?
The glaze adds the “donut” effect, but the cake can also be enjoyed plain or with a dusting of sugar.
