5-Minute Chocolate Mochi Mug Cake
This rich and chewy chocolate mochi mug cake version takes just 5 minutes start to finish and is absolutely delicious! Sweet rice flour and cocoa powder are the main ingredients, leading to a moist rich chocolate cake that's similar in density to a brownie, but incredibly stretchy and chewy.

Ingredients
Quantities are shown as originally provided.
- 2 tablespoons sweet rice flour
- 1 tablespoon granulated sugar
- 1/2 tablespoon unsweetened Dutch-processed cocoa powder (I use Rodelle cocoa powder)
- 1/8 teaspoon baking powder
- 1/2 tablespoon vegetable oil
- 2 tablespoons non-fat milk (or soy milk)
- Optional: powdered sugar for sprinkling on top
Instructions
- 1
Whisk together all of the dry ingredients in a medium microwave safe mug (I used a 4-ounce tea cup in the photos above and it just reaches the very top, so I'd recommend using 4-ounces or larger).
- 2
Add the wet ingredients and use a fork or a small whisk to mix until the batter is smooth.

Cook in the microwave for 1 minute. If the cake is not done, heat an additional 15 seconds. Sprinkle with powdered sugar and serve immediately.
