Expert Baking Tips on how to make this quick easy microwave cake
Although this egg free microwave cake recipe is super simple to make, here are just a few expert tips i'd recommend:
- Add a teaspoon or two of muesli to your mug cake to add more texture for the crumble topping.

- The cake is ready when the sponge springs back when touched.

How make microwave cake vegan
Microwave cake recipe no egg - Ingredients
Here's everything I used to make this microwave cake without egg
Vegan butter- You can use either vegan block butter or margarine.
Water - A very small amount is required and is needed to bind the crumble together.
Sugar- I like to use caster sugar which is just a very refined sugar, but if you don't have any refined granulated sugar will work well here.
Gluten free Plain flour - If you’re gluten free flour doesn't already have xanthan gum add a teaspoon to the dry ingredients. This will help add stability to the cake and prevent it from crumbling.
Banana/Apple puree - This will act as the egg substitute.
How to bake microwave cake - Step-by-step instructions
Microwave crumble topping
- Start by making the crumble this by rubbing the flour sugar and butter together between your fingers then add the water and musli and mix.

- Make the cake mix by creaming the butter and sugar then add the milk and vinegar.
- Next, add the dry ingredients.

- To assemble all the parts for this cobbler begin by microwaving the fruits and crumble for 2mins to release some of the fruit juice.
- Next, pour the cake mix into the mug leaving a ¼ behind for the top.
- Layer the fruit mix on top, leaving as much juice from the fruit behind.
- Finally add the remaining cake mix to the top and microwave for 3 mins, at 30sec intervals to prevent the cake from rising above the mug and flowing out.
- Serve with a scoop of ice cream and enjoy!
