Step-by-Step Instructions
Now, let’s get into the fun part—making your low calorie chocolate mug cake!
- Grab your favorite mug: Make sure it’s microwave-safe and has a bit of room for the cake to rise.
- Whisk the dry ingredients: Toss the flour, cocoa powder, sweetener, baking powder, and salt directly into your mug. Whisk until there are no clumps.
- Add the wet ingredients: Pour in the milk, oil (or applesauce), and vanilla extract. Stir until everything is just combined.
- Pop it in the microwave: Place your mug into the microwave and zap it on high for about 60 seconds.
- Check for doneness: After 60 seconds, take a peek. If it’s still super wet, give it another 15-30 seconds, checking frequently.
- Cool (if you can wait): Let it sit for a minute or two before enjoying. It’s the hardest part, I know!
Pro Tips for the Perfect Mug Cake
