Linda Loo's Just Add Water Chocolate Mug Cake Mix Recipe from More With Less Mom

Linda (kid #2) when she was littleWelcome to my quest for a homemade chocolate mug cake mix recipe! I am obsessed with chocolate. There are times when I NEED chocolate. If there is chocolate cake in the house, I will eat it. All. It’s a problem.

A while back people went bonkers for Warm Delights: warm, tasty desserts in little cups you zap in the nuker. I got one with a coupon and an overstock sale when they first came out, and couldn’t afford them ever again.
Shortly after there was a flood of recipes for these mug cakes. Quick, tasty, and not nuked in a plastic bowl (mmm plastic).

The thing I didn’t like about the bulk of these recipes was adding egg (costly and it makes me nervous), and many of them started with a box of cake mix. Not so helpful when you’re trying to cut out prepared foods and their associated additives.

I tried omitting the dry milk and mixing it with milk, and got a drier, more cakey cake. I tried omitting the salt, but it was so fudgy it was gooey.

My recipe follows, but is by no means original. Chocolate cake can never be overdone, though.

This is suitable for gift giving. It makes a rich, fudgy cake.

This recipe has been calculated for a single cake or a bulk batch of mix. 4 Tbl of mix filled my mug about half full, it does rise a little when cooking. This amount of mix will make 22 small cakes, or if your mug is big enough for a double batch it will make 11.

Batch Yield: Mix for 11-22 mug cakes

  • 2 cups flour
  • 1 1/2 cups sugar
  • 3 teaspoons baking powder
  • 1/2 cup dry milk
  • 1/2 cup cocoa
  • dash salt
  • optional to mix in: chocolate chips, peppermint chips, peanut butter chips, butterscotch chips, coconut flakes, various extracts
  • optional to top: chocolate syrup, strawberry syrup, whipped cream, powdered sugar, baking cocoa…

Single Yield: Mix for 1 mug cake

  • 2 Tablespoons flour
  • 1 Tablespoon sugar
  • 1 1/2 teaspoons sugar
  • 1/4 teaspoons baking powder
  • 1 Tablespoon dry milk
  • 1 Tablespoon cocoa
  • pinch salt


  1. Combine all dry ingredients.
  2. Mix 4 Tbl mix with 2 Tbl water (or milk if you want it more cakey) in a bowl or mug. Make sure you get those corners on the bottom mixed.
  3. For most mugs you can double this and it will fit, it does rise a tad.
  4. You can add chocolate chips if you prefer.
  5. Cook in microwave for 40 seconds (it takes longer if you double it or use milk). If it still looks wet keep cooking for 10 second intervals. Your cake should look dry on top. If you aren’t sure use a spoon to pull the side of the cake away from the mug and see if the bottom is wet. No raw egg, so a little wet won’t hurt you. You don’t want to overcook these.
  6. Let rest for 2 minutes.
  7. Top with chocolate sauce.
  8. Serve warm. Om nom!
