Preheat oven to 350 degrees.
Mix dry ingredients in a medium-sized bowl: flour, salt, baking powder, baking soda, and sugar and set aside.
Using an electric mixer, mix wet ingredients: butter, cream cheese, vanilla, egg, and peaches.
Slowly add dry ingredients to the wet ingredients
Refrigerate dough for 30 minutes. You can skip this step if you're in a pinch, but the cookies won't form balls quite as easily.
Roll dough into balls using your cookie scoop. Dust each ball with powdered sugar and place evenly on a baking sheet lined with parchment paper.
Bake cookies for 10-12 minutes.
Let cool and serve.
