Apple Cinnamon Muffins

Preheat oven to 350 degrees F. Line a 12-cup standard muffin tin with paper liners. Set aside.

In a large bowl, whisk together the butter, granulated sugar, brown sugar, buttermilk, egg and vanilla until well-combined.

Add the flour, baking powder, cinnamon, baking soda and salt. Whisk until just combined (it's ok if there are a few dry streaks).

Add the apples and stir until evenly combined - don't over mix.

Divide the batter evenly among the muffin tin, filling the cups 2/3 full.

Sprinkle the top of each muffin with a bit of coarse, turbinado or brown sugar, if using.

Bake for 17 to 18 minutes until the tops of the muffins spring back lightly to the touch.

Remove the muffins from a tin to a cooling rack to cool completely. These muffins are tasty warm, but even more delicious as they cool and the flavors have time to deepen.
