Notes

Storage
Fridge: Store in the fridge for up to 5 days. 
Freezer: Store in the freezer for up to 3 months.
Room Temperature Egg
It is important to use an egg that's been brought to room temperature. You can do this by taking the egg out of the fridge 30 minutes before, or you can fill a bowl with warm water, add the egg from the fridge and let it sit for 5-10 minutes to come up to temp. 
Weigh Ingredients
This is the best way to ensure that you get consistent results, every time. If you add too much flour you'll end up with dense cupcakes. Using a kitchen scale is the easiest way to ensure consistent results. If you don't have a scale, be sure to always spoon and level your flour. 
Don't skip aeration! 
Sifting the ingredients removes clumps and aerates the dry ingredients to ensure a light and airy chocolate bottom. 
Always use liners
Be sure to use mini muffin tin liners for this one!
