Banana Espresso Chocolate Chip Muffins

Great Excellent* muffins. I love adding instant espresso powder to desserts and baked goods. The result is richer without tasting the espresso. Amy gave me this tip a couple years ago when I was baking brownies and now I'd never bake brownies again without it.

The recipe I used for these muffins is found here.

*Edited this post the next day: These are awesome. They should not be described as "great".
