Quick Walk Through: Eggless Blueberry Microwave Mug Cake

Why You’ll Love This Cake
- This mug cake is perfect for all your cake cravings – it’s soft, fluffy and slightly gooey with all those blueberries in there. They burst and left all this juice running out of the mug; more specifically tea cup in my case.
- Takes exactly two minutes from start to finish if you have everything on hand.
- The ingredient list is all of seven ingredients long. Which means you’ll probably have everything you need at hand.

Frequently Asked Questions
This depends on the strength of your individual microwave. It took me about 80 seconds for my cake to be fully baked. I would recommend cooking the cake for a minute to see if it’s done. If you notice it’s gooey or undercooked, stick it back into microwave in 30 second intervals until it’s done.
Since this cake is so simple and quick, I would recommend making it fresh every time. But during testing this recipe, I had like 10 mug cakes that I couldn’t possibly finish in a day. And these extras lasted in my refrigerator for two days.
Absolutely! Since this cake has no eggs, it is already vegetarian. However you can easily make it vegan by replacing normal milk with any plant-based milk of your choice.
Swap the blueberries for strawberries, chocolate chips, cranberries, sprinkles, raspberries … and see how you have a new mug cake every time!

Top Tips To Make The Best Microwave Mug Cake
- Use a microwave safe mug or ramekin bowls to make this cake. Also, the mug is going to be really hot, so don’t forget to use oven mitts when taking the mug out after the cake is ready.
- Do not fill the mug to the brim or the cake will spill out as it rises. To avoid this fill the mug only about halfway to two-thirds full and no more.
- Make this cake gluten-free by replacing all purpose flour with a gluten-free flour like almond or chickpea. However, gluten-free flours usually require more liquid, so make sure to adjust the quantity of the milk according. However, gluten-free mug cake will have a slightly different taste and texture, but it will still be good.
- If overcooked, this mug cake can become rubbery very fast. To avoid that check the cake after a minute and then at 30 second intervals after that.
At this point I love them so much that I’m only going to be serving mug cakes at the next party. Who needs real cake when you can have mug cake, ready in two minutes in a microwave?! Plus the flavors and the combinations; I can’t even! Yay for quick cooking, single serving mug cakes!

Eggless Blueberry Microwave Mug Cake
Ingredients
- 2 tablespoons Butter, melted
- 2 1/2 tablespoons Sugar
- 2 tablespoons Milk
- 1/2 teaspoon Vanilla extract
- 1/2 teaspoon Baking Powder
- 1/4 cup All Purpose Flour, or Maida + 1 tablespoons
- 7 – 8 Blueberries
Instructions
- In a bowl, whisk together butter, sugar, milk and vanilla extract.
- Add baking powder and flour and whisk till combined. Mix in blueberries and pour into two microwave proof tea cups or one mug. Only fill the cups or mugs halfway because the cake rises up quite a bit. To clarify, this recipe is enough for one mug but I was able to divide it into two when I used two tea cups.
- Microwave for 1 minute on high. I have a small microwave and I’m not sure about the wattage. Cooking time would vary slightly depending on the size of your microwave, so I recommend starting with 45 seconds and increasing by 30 seconds.
- Serve the blueberry mug cake dusted with sugar and topped with more blueberries.
Notes
- Storage: keep it in the refrigerator for a day or two in an airtight container.
- Swap the blueberries for strawberries, chocolate chips, cranberries, sprinkles, raspberries.
- If preferred, bake it in the oven at 350°F (180°C) for 15 – 25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe muffin mould.




Just what I needed to satisfy a random pregnancy craving! I substituted the sugar with honey and it still turned out as light and fluffy as promised!
Great
Thanks Melina!
This was alright, but way too sweet. We would use a lot less sugar if we were to make this again.
Just tried this and the cake completely collapsed in the mug 🙁 any idea why?
I’m not sure what you mean by collapsed?
I finally broke down and made this recipe for breakfast today. 🙈 LOL! I’m gluten and dairy free so I substituted my ingredients with plant based butter, agave nectar, coconut milk (beverage), gluten free measure for measure flour and frozen blueberries. I’m happy to say that it turned out great. I was pleasantly surprised and will definitely make this again. Thank you for taking the time to create a good recipe foundation.
This is such a treat! So glad you liked it Lacey
you can sprinkle chia seeds too.
Sure, Jim! Go ahead, but I refuse to make this mug cake a healthy recipe 😛
Turned out so well! Just what I needed on a lockdown afternoon. I didn’t have vanilla extract so added a pinch of cinnamon powder and it tasted yum.
