5-minute Chocolate Cake





Introduction: 5-minute Chocolate Cake

There are a lot of 5-minute cake-in-a-mug recipes out there, but I've taken the time to experiment with eight variations on a a recipe to come up with the best, tastiest, and most reliable 5-minute chocolate cake on the web.  This quick and easy chocolate cake recipe will change your life! Now you can have a rich, chocolate dessert in an instant.  So grab a big mug (I link to my favorite in the next step) and get ready to make new kind of cupcake - the cake in a cup!

Step 1: Supplies


  • 4 tablespoons flour - make sure you measure it right - or the cake is a lie!
  • 4 tablespoons sugar
  • 1 tablespoon unsweetened cocoa
  • 2 tablespoons whisked egg - 1 egg is too much, 1 egg white is too eggy, 1 yolk is too dense, but 2 tblsp is just right!
  • 3 tablespoons milk
  • 3 tablespoons oil
  • 3 tablespoons chocolate chips
  • splash vanilla or other flavoring - try peppermint or cinnamon
For a fudgier version, omit egg.

Step 2: Mix Your Ingredients

  • Add all of the dry ingredients to the mug and mix.
  • Add the egg and combine well. It gets pretty pasty at the point.
  • Stir in milk and oil.
  • Add chocolate chips* and splash of vanilla. Stir well.
*if you don't have chocolate chips, try a broken up candy bar - I can't stress how much this amps the awesomeness of your cake

Step 3: Nuke It!

  • Microwave for 3 minutes in a 1000w oven, or 4 minutes in a 700w oven.
It will start to crown over the top of the mug. Don't panic! It will collapse once the heat stops.

Step 4: Experiment!

Some people have had mixed results with the final texture of this cake.  

This cake is tricky mostly because of people's microwaves all being different.  I experimented a lot with the amounts of different ingredients. 

I think if it's something you're going to make quite a lot in the future, it's worth fussing around with!  Try just a bit less time in the microwave (you can always put it back in for more).  If that doesn't help, try a little less egg, or a little less flour. 

Keep notes on what you're trying each time, and eventually you'll find the cake that's perfect for both you and your microwave!

There are so many bad versions of this recipe everywhere but yours really works Thankyou :D

does not it wrecked my cup

I think you used a non-microwaveable cup. Some cups can't go in the microwave, such as plastic, because it could melt or deform.

Use an oversized mug. That cured it from wrecking my mug again!!

Thank you!
I actually experimented with about 6 different variations of the recipe before I decided that this one was the best.

these things are optional

  • splash vanilla or other flavoring - try peppermint or cinnamon

For a fudgier version, omit egg.

for a first timer with zero baking experience, it worked like magic! thank you.


yum! This recipe has come out great all three times I've used it. I love to add cinnamon, chili powder, nutmeg... whatever I have around.

I mix the batter in a small bowl and then pour it into two smaller oiled mugs and cook for about a minute.

In the picture below I added semi-sweet and white chocolate chips. Then melted a bit of the white chocolate and decorated the tops.


After some instant microwave cake disasters, this recipe came out great! I've tried a few microwave treats, and this was the only one that came out on the first try. It was delicious! It also looked like it needed frosting. We didn't have any, so I used chocolate sauce.

Oh, this is terribly dangerously DANGEROUS to know. :-) My mugs are pretty small, so I made this in a bowl, which required reducing the cooking time to about 1: 45. I omitted the egg for a fudgier result, and it's a wonderful cake/brownie hybrid. I chopped up 3 tablespoons' worth of Hershey with Almond bar, since it's all I had; I also made a glaze with about 3 tbsp. confectioner's sugar and just a few drops of milk. DAN. GER. OUS. It's incredibly rich and I'm not sure I'll be able to eat the whole thing, but dangit, I'm trying.
