Preheat oven to 350 F. Line muffin cups with 8 jumbo papers or 12 regular size papers.
Using an electric mixer, cream together butter & sugar then add applesauce, eggs & vanilla & mix until smooth.
In a bowl, whisk together flour, baking powder, salt & 5-spice powder.
Add flour mixture to wet mixture, folding in only until barely combined then add diced pear & gently fold into mixture.
Scoop the batter evenly into prepared muffin tin. Divide topping between muffins & gently spread over top using a fork. Bake 25-30 minutes & a toothpick inserted into center comes out clean.
Cool for 5 minutes before removing from muffin tin.
