The classic flavor combination of apple + cinnamon, in an ultra-soft sourdough muffin. These are so easy, and SO delicious, they're bound to become a breakfast staple!Makes 12 muffins.

Line a muffin tin with paper cups.Whisk together the butter, starter, milk, eggs, and vanilla in a large bowl until smooth.Combine the flour, baking soda, salt, sugar, cinnamon, and nutmeg in a medium bowl. Sprinkle the dry ingredients over the wet ingredients and stir to combine. Fold in the shredded apple.Divide batter between prepared muffin tins. Sprinkle with turbinado sugar. Bake 22-25 minutes, until muffins are domed, baked through, and golden brown.
Notes
Apple varieties - I like to use a sweet apple (Honeycrisp or Fuji) for these, but any variety will work! Just keep in mind it will affect the flavor of the muffins, so if you're using a less sweet apple (like a Granny Smith or McIntosh), your muffins won't be as sweet.
