2Granny Smith or baking applespeeled and finely chopped (3 cups or 315 grams apples)
Cinnamon Sugar (optional)
Preheat oven to 350 degrees F.
In a large bowl, whisk together yogurt, applesauce, eggs, milk, vanilla and brown sugar until smooth.
Add baking powder, baking soda, cinnamon and salt and whisk until combined.
Fold in flour and apples with a spatula, just until moistened and no flour remains.
Lightly grease a non-stick muffin pan or fill with paper liners, and fill muffin cups to the top (you can also make smaller muffins but they will bake more quickly).
Bake for 20-25 minutes, until a toothpick inserted in the center comes out clean or with moist crumbs. Let cool for 5-10 minutes in the pan before removing to a wire rack to cool completely. (If using paper liners, they will be easier to remove after several hours has passed)
Cinnamon Sugar (optional)**
Brush butter over tops of slightly cooled muffins.
Stir together cinnamon and sugar. Sprinkle over muffins before serving.
Store muffins uncovered at room temperature on the day you bake them. To store longer, place in an airtight container and refrigerate up to 5 days or freeze up to 3 months.
*These muffins are not overly sweet but I find them perfect with the cinnamon sugar topping. If you are not going to use the topping, or you like muffins a little sweeter, you can add an extra 1/4 cup sugar to compensate.**Muffins with the cinnamon sugar topping are best eaten that day. Once they are sealed and stored, the sugar will lose its crispness and become moist. They are still tasty, it is just the texture that will change.
