Good News Banana Flax Mini-Muffins

For the second morning in a row, I woke up today to find good news in my inbox. This morning's good news: my lab meeting this afternoon got canceled. Naturally I wanted to celebrate by using my morning for crafting and blogging rather than preparing for a meeting after work. With the 100˚ days we've been having in Upland lately, my bananas have turned black on the counter, and no one likes a black banana, so I decided to make some banana bread.
I adapted a recipe I found at food.com for these delicious and healthy little breakfast treats
