The great thing about chocolate mug cake is this quick recipe that transforms simple ingredients into a warm and soft cake, straight in your cup. No long dishwashing, no oven to preheat, just 5 minutes and there you are, in chocolate heaven. Well, it’s not necessarily the most elegant recipe, but oh boy, it’s so good!
I always have that reflex of slightly overcooking or undercooking it, because naturally, every microwave heats differently. So, I recommend watching your cake the first time, the texture can quickly change from soft to a bit rubbery (yes, I tested, annoying!). But honestly, once you get the hang of it, it’s perfect.

For those hesitating to try, know that this recipe is designed for a solo dessert, a little comfort after a busy day. Or just to treat yourself on the couch in three spoonfuls – or rather, in three spoonfuls in the mug!
Ingredients for an express chocolate mug cake
- 1 egg (essential for the soft texture)
- 3 tablespoons of sugar (a touch of sweetness)
- 3 tablespoons of flour (the cake base)
- 2 tablespoons of unsweetened cocoa powder (for the chocolate flavor)
- 3 tablespoons of milk (to make the mixture nice and liquid)
- 2 tablespoons of vegetable oil (to keep the softness)
- A pinch of baking powder (optional, I often add it)
How to prepare your chocolate mug cake in under 5 minutes
I’ll tell you how I do it, but well, adapt to your pace and your microwave. It’s not rocket science, I promise.
- In a large mug (avoid very small ones, or else watch out for spills!), crack the egg.
- Add the sugar, then whisk a little with a fork, just so it mixes.
- Mix in the flour, cocoa, baking powder (if you add it), then stir well to get a homogeneous batter.
- Pour in the milk and oil, mix again, it should be smooth, without lumps.
- Put in the microwave, max power, between 1 minute 30 and 2 minutes 30. I go slowly, often check, that’s the secret not to turn it into rubber.
When taking out the chocolate mug cake, be careful, it’s hot, so better wait a few moments before plunging the spoon. That moment when you touch the texture, feeling the chocolate still melting a bit… I love that.
Tools for a successful cake in a cup
- A mug large enough and microwave-safe (avoid plastic ones)
- A fork, essential for effective mixing
- A spoon to savor (and even, you can scoop straight with the fork)
- Microwave, naturally, for quick cooking
Variations and personal little tips
- Do you like it very chocolaty? Add chocolate chips or a square of chocolate in the center before cooking.
- For a lighter version, I replace the oil with applesauce, it works very well.
- Sometimes I add a pinch of cinnamon or vanilla to twist the recipe, and it changes everything.
- If you’re really in a hurry, some use oat flour for a more rustic and filling touch.
I don’t bother myself, I sometimes make two chocolate mug cakes in a row, because well, when it’s too good, you share… or not.
Can you prepare mug cake without a microwave?
Yes, you can bake it in a traditional oven, in a small ramekin, at 180°C for about 10 to 12 minutes. But it will be less quick and with a bit more washing up.
How to avoid the mug cake being rubbery?
Watch the cooking, it must be just long enough to cook the cake without drying it out too much. Every microwave is different, so test the power and time.
Can you replace the sugar in the recipe?
Absolutely, you can use agave syrup, honey, or a sweetener, but this slightly changes the texture and cooking.
How to make the mug cake even more indulgent?
Add pieces of chocolate, a bit of whipped cream, or even a scoop of ice cream right after the microwave. It’s delicious!
Is this recipe suitable for children?
Yes, this recipe is simple and quick, perfect for introducing children to baking. Just watch the cooking to avoid it turning out too hard.
