Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Cream together butter and cream cheese with granulated and brown sugars until smooth and fluffy.

Add the egg and vanilla to the mixture, mixing until fully combined.

Whisk together the flour, baking powder, cinnamon, and salt in a separate bowl, then combine with the wet mixture.

Fold in the diced apples until evenly distributed.

Drop rounded balls of dough onto the prepared baking sheet, spacing them 2 inches apart.

Bake for 12-15 minutes until golden around the edges but soft in the center.

Cool the cookies on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.

Store in an airtight container at room temperature for up to three days or in the fridge for up to a week.
