Instructions
In a small mixing bowl combine all mug cake ingredients except the flour (and not the crumb topping ingredients). Mix until everything is well combined and smooth. Then mix in the flour until smooth again.
In another small bowl, combine all of the crumb topping ingredients. Use a fork to mix the ingredients together until a crumb-like texture is formed.
Pour the cake batter into a microwave-safe mug and top it with the crumb mixture.
Microwave the mug cake for 1-1 ½ minutes, or until baked through. Leave it in the microwave to rest for at least 1 minute before serving.
Notes
A pinch of salt is roughly 1/16th of a teaspoon.
A mug that is not tapered and is the same size all the way around will cook your mug cake the most evenly.
Place a paper towel beneath your coffee mug when baking in case of overflow.
To check if the mug cake is baked through, stick a toothpick in the center. If it comes out clean, it is ready. If it comes out with wet batter on it, microwave it for a few more seconds and check again.
Your mug cake is best right after baking but should you need to refrigerate it, do so in an airtight container for 2-3 days. This equally delicious when served cold, so no need to reheat!
