Want chocolate cake, and want it now? Satisfy that insistent cake craving with a Microwave Mug Cake…it’s quick work to chocolate goodness!

Quick time cake

Sometimes I want cake, and I want it n-o-o-o-o-o-w. Nothing fancy, no gimmicks or frills…just give me cake. I don’t even want to wait the 35-40 minutes it takes to bake a cake, or have leftovers to get stale. Not even something as easy as Kahlua Cake will fit the bill. Nope, just give me a good old-fashioned single serving of cake that I can eat almost immediately and almost anywhere, and no one will get hurt. Enter, Microwave Mug Cake, stage left.

(wait, did you say microwave?)

5 Minutes to cake

You read that right…you can bake a cake in a coffee mug in the microwave, and in 5 minutes you’ll have a something ready to quell that insistent cake monster (well, maybe add a couple of minutes to let the cake cool, but that’s just the time it takes to wash the dishes before digging in). It’s quick, easy, chocolate-y goodness that soothes that whiny child within. Usually my husband and I will share a mug (I find that half is enough to satisfy my cake cravings), but the original recipe says 1 serving…I’ll leave that decision up to you (table for 1, please!).

Want a full-sized cake?

Ok, if you must. This microwave mug cake is a just a scaled down version of what I call Oil-and-Vinegar Cake, a simple yet satisfying recipe that bakes up in a 9-inch cake pan…the scaling down works because the recipe doesn’t contain eggs so there’s no partial eggs to waste. To scale the recipe back up, just multiply all the ingredients by 4 (see the Recipe Notes for the list) and bake at 350ºF for 30 minutes. There, now you can share.

Chocolate cake in 5 minutes? Yes, please!


Oh, you can doll up the cake if you wish by mixing in the batter chocolate chips, jam (raspberry is my favorite), or even sprinkles. How about topping the baked cake with chocolate chips while the cake is still warm so they get all melty? Or let the cake cool, then top with powdered sugar, frosting, ice cream, caramel or whipped cream…whatever suits your fancy. So when that irresistible urge to have cake now strikes, reach for a bowl, a whisk, and a mug…after all, why wait?

Slainté! L’chaim! Cheers!

Recipe Notes

Each microwave cooks differently, so adjust time accordingly. Be sure to watch as it bakes so it doesn’t overcook.
This recipe makes 1 cake in a mug, but you can decide if that is 1 serving or 2. I won't judge.
You can make other cake flavors with just a few alterations:
  • Mocha: Replace the hot water with hot coffee
  • Vanilla: omit cocoa powder and increase the vanilla to 2 tsp
  • Spice cake: omit cocoa powder and add 1/2 tsp cinnamon and 1/4 tsp each nutmeg, cloves, & ginger
  • Pumpkin: omit cocoa powder and use the spices above & add 1 Tbsp pumpkin purée
For a full-sized cake, scale the recipe up by 4:
  • 1 1/2 cups (180g) all-purpose flour
  • 1 cup (200g) granulated sugar
  • 1/4 cup (20g) cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 Tbsp white or cider vinegar
  • 1 Tbsp vanilla
  • 1/3 cup canola oil (66g)
  • 1 cup hot water 
Pour the cake into a 9-inch square baking pan and bake at 350ºF for 30 minutes or until a tester comes out clean.
