Apple Coffee Cake Muffins

1.  Preheat oven to 350 degrees.

2.  Line a 12 cup muffin tin with paper liners or cooking spray.

3.  In a medium bowl, combine chopped pecans, brown sugar, and cinnamon. Mix well and set aside.

4.  In a large bowl, combine flour, sugar, and salt. Cut 8 tablespoons of butter into ½ inch pieces and sprinkle evenly over flour mixture.

5.  Using a pastry blender, cut the butter into the flour mixture until butter is oat-sized.

6.  Remove 1 cup of the flour-butter mixture and stir into reserved brown sugar mixture until combined to make streusel- set aside. 

7.  Add baking powder and baking soda to remaining flour mixture and stir to combine.

8.  In a liquid measuring cup, whisk together sour cream, egg, and vanilla.

9.  Add liquids to flour mixture and stir until just combined.

10.  Add 3/4 cup of streusel mixture to flour mixture and stir until streusel is just distributed throughout batter. 

11.  Melt the remaining butter and stir into remaining streusel mixture, until streusel resembles a crumble. 

12.  Gently fold apples into batter.

13.  Divide batter among 12 muffin cups and sprinkle generously with streusel topping, crumbling with your hands to make some big chunks. 

14.  Bake 22-24 minutes, or until a toothpick inserted in the center of muffin comes out clean. 

15.  Allow to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

16.  To make the glaze, whisk the confectioners' sugar, milk and vanilla extract together. 

17.  Drizzle over muffins & enjoy!
