Ah, Saturday morning. I love acting like I have nothing to do except curl up with some coffee and homemade muffins. Ignoring my to-do list is one of my most favorite activities. Banana & Blueberry Buttermilk muffins with a crunchy sweet topping are the perfect fodder for a lazy Saturday morning.I found myself with a lot of buttermilk on hand after making something else (more on that later) that only called for a small amount. I was going the way of buttermilk pancakes until I came across this recipe from Eating Well. I followed it closely with the exception of using whole wheat flour and low-fat buttermilk (I used all-purpose flour and full fat buttermilk). Oh, and I added a topping from a recipe I found here that’s just sugar, flour, butter and cinnamon all mix up together. Another note: for some reason the muffin recipe produced batter for more than a dozen regular sized muffins, so it made about a batch and a half in the end. Which is okay because they’re pretty good and you will want to eat more than just one. Especially if you do the sweet topping part.
