One Saturday morning, a fresh batch of banana muffins came out of the oven. The aroma wafted up, up, up, into the apartment above. And down, down, down came a mysterious thumping on the staircase. I grabbed my handy grandma-cam, and managed to snap a few photos of the mystery intruder. Aha: The Case of the Missing Sugar Crusty Banana Muffin Bite solved! That's probably all the endorsement you need for these irresistible muffins, except that they're super-easy to make if you have a ready-for-the-compost couple of bananas sitting on the countertop. Sugar on top makes them crusty; if you'd like to cut back on the sugar, add the cinnamon to the batter and eliminate the final topping. Cinnamon and banana, plus good-quality pure vanilla extract, gives these muffins a bit of Caribbean flavor to start your day. The dozen muffins I baked for breakfast disappeared in minutes.
