I prefer leaving the skin on my apples for both fiber and color, but peeling them is probably what most folks prefer to do. These muffins are moist and lightly sweetened and each little piece of apple still retains a little crunch with the kind of apple I used. They were delicious warm, spread with a bit of softened butter and would be great eaten as a snack, spread with a little smear of peanut butter, too. My favorite way to eat them though is “as is” just popped into my mouth (in two bites). The aroma they created while baking was amazing. There is just something about the smell of apples and cinnamon wafting through the kitchen while you are baking on a cool fall morning.
I'm going to make another batch of them this weekend. I think they taste even better the next day after the apple flavor and moistness has worked its way throughout the muffin. I recommend you cut your apples into small dice (1/4" or so) so the apples get distributed evenly throughout all the muffins and you get a bit of apple in each bite. Also, I want to share one interesting thing that I noted. I baked 2 dozen muffins at a time and refrigerated the batter uncovered until I was ready to put the 2nd batch in the oven and I to. I noticed that the 2nd batch of muffins that's batter had sat for about 25 minutes rose higher and were fluffier than the first batch baked right after mixing (they had nice rounded crowns). It was noticeable enough for me to purposely place the entire bowl of batter in the fridge to sit for 20 minutes or so before scooping and baking all of them next time. The recipe and photos are below. Enjoy!
