Microwave Mug Cake with spoon inside

This is such a great treat if you want to treat yourself, treat a special someone or teach your kids how to make it so they can surprise you on your birthday. The latter is my plan and I’m optimistic for this year with my kids being older! If you love the idea of making food in a mug, be sure to check out my Pasta in a Mug!

How do you make a mug cake

  1. Grease a mug with cooking spray. Measure all the ingredients and place them directly into the mug.
  2. Use a small fork or whisk to blend the ingredients together until you don’t see any more lumps.
  3. Microwave for 90 seconds on high. Then remove from the microwave and allow it to cool for 5 minutes before enjoying.
Step by step shots for how to make a mug cake

Tips for making mug cake

  1. Use a mug wide enough for about double the batter. When cooked in the microwave, the batter will expand almost double the size, so make sure the mug is large enough for the expansion.
  2. Use a mug with straight sides if possible. I love a fun wide mug which is what I use here, but straight sides will help the mug cake bake evenly all around. Since this is a vegan mug cake, we don’t have an issue with eating raw eggs if anything is under cooked!
  3. Place a plate or paper towel under your mug if its not large enough. There might be some overflow happening, if you only have a small mug, so this trick will help keep the microwave clean.
  4. Test your microwave strength to determine the best time. It can range from 1 to 1 ½ minutes, but I found the ideal time for mine was 1 ½ minutes. Keep in mind that wider mugs will cook faster than taller mugs.

Frequently Asked Questions

Can you make a mug cake ahead of time?

Because these cakes only takes minutes to make, they are easy to whip up whenever you want! If you do have leftovers, you can keep them in an airtight container in the fridge for up to 3 days.

Can you make a mug cake in the oven?

If you don’t have an oven. don’t fret, you can still make these delicious cakes! Whisk the ingredients together in bowl and pour it into a greased oven proof ramekin. Bake in the oven for 15 to 20 minutes at 350F.

Can you add toppings to a mug cake?

This cake is pretty perfect as is, but if you want to add some toppings to make it extra special, I won’t stand in your way! Chocolate shavings, some whipped cream or a dusting of powdered sugar will all work well.

Cake made in a large mug with sprinkles

What a fun treat to make a cake in a mug in just a couple minutes! I love enjoying this in the evening sometimes when I don’t want to make a mess and don’t need to feed the whole family a large cake. The sprinkles make the mug cake extra fun for a birthday or any other celebration!

P.S. Today is MY birthday!! 🙂

  1. Since I’m allergic to Almonds and Grapes and Vanilla. I can use Vanilla Imitation but
    what can I substitute for the Almond milk and grapeseed oil, which I have never heard of. Thank you. It’s a nice idea for that cake.

  2. Can this be made with whole milk instead of the almond milk and avocado oil or olive oil instead of the grapeseed oil? Thank you!

  3. I just had a sweet craving and looked up your mug cake recipe. It absolutely blew my mind. It is so simple and quick. Thank you so much for sharing.

  4. My son is allergic to dairy and egg. This is his all time favorite dessert! Thank you so much for this recipe and all the others you have on your site. 🙂
