Preheat your oven to 350°F (175°C).

In a mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.

Mix in the apple butter and eggs until well combined.

In a separate bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt.

Gradually add the dry mixture to the wet ingredients, mixing until just combined.

Using a cookie scoop or spoon, drop rounded tablespoons of dough onto a parchment-lined baking sheet.

Bake for 10 to 12 minutes, or until the edges are lightly golden.

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