Learn how to make a chocolate chip mug cake from scratch that you cook in the microwave in 90 seconds or less! This quick and easy recipe makes cake for one without eggs and is ready in under 10 minutes from start to finish.
In a microwavable mug (make sure that it has a 1-cup capacity, ~250 mL, and is microwave-safe), stir together with a fork the flour, brown sugar, chocolate chips, baking powder, and salt.
Measure the milk, oil and vanilla directly into the mug. Stir again until there are virtually no more lumps. Make sure to scrape the bottom edges to make sure there are no flour pockets!
Top with more chocolate chips if you want.
Place the mug in the microwave, and cook on high for 90 seconds. The cake will puff up as it cooks. Use a cake tester and insert it into the centre of the cake to test if it's done cooking.
Carefully take the mug out of the microwave (it’s hot!) and let the cake sit for a couple of minutes before diving in with spoon. You can also top it with ice cream and sprinkles.
Notes
For the chocolate sprinkles, I used some imitation chocolate sprinkles from the grocery store. Cute in theory, but they are actually just dyed sugar and so the colour bled onto the ice cream. If you can, try to buy real chocolate sprinkles, like these on Amazon which are made with cocoa powder, not food dyes.
