Why choose a chocolate mug cake?
Perfect for one serving

Quick and convenient
From mixing to microwaving, this cake takes less than 10 minutes. That's faster than a trip to the store for packaged snacks.
No oven, no mess
All you need is a mug, a fork, and a microwave. Cleanup? Just one mug to wash.
Ingredients you'll need
This easy chocolate mug cake recipe uses basic pantry ingredients. Chances are, you already have everything on hand.
- Flour - all-purpose works best
- Sugar - balances the cocoa
- Cocoa powder - unsweetened, for that deep chocolate taste
- Baking soda - makes the cake rise
- Salt - just a pinch to boost flavor
- Milk - keeps the cake moist
- Oil - use a neutral one like canola
- Water - helps with texture
- Vanilla - just a dash for a warm finish
Optional: chocolate chips, whipped cream, or a scoop of ice cream on top.
How to make your quick chocolate mug cake
Step 1: Prepare the mug
Choose a microwave-safe mug that holds at least 12 ounces so your cake has room to rise.
Step 2: Mix dry ingredients
In the mug, stir together flour, sugar, cocoa powder, baking soda, and salt.
Step 3: Add wet ingredients
Pour in milk, oil, water, and vanilla. Stir until the batter looks smooth with no lumps.
Step 4: Microwave
Cook on high for about 1 minute 45 seconds. Microwaves vary, so check at 1:30. The cake should look set but soft in the middle.
Step 5: Cool & enjoy
Let the mug cool for a minute (it'll be hot!). Then dig in with a spoon-or add ice cream for extra fun.
