Whisk the flour, baking powder, and cinnamon together in a bowl and set aside.
In a larger mixing bowl, cream together the butter and sugar. Then add one egg and mix well.
Add the second egg, vanilla, and apple butter, mixing to combine.
Add the dry ingredients and mix until it comes together. Warning: it will be a very soft and sticky dough.
Wrap the dough in plastic wrap or cover the bowl and chill in the fridge for 3-4 hours to make it easier to handle.
Preheat your oven to 350℉. Line your baking sheet with parchment paper. Mix up the cinnamon-sugar topping in a shallow tray to roll dough balls in.
Use a spoon or scoop, separate the dough into one tablespoon balls. Roll these up and roll them in the cinnamon-sugar topping to coat.
Place each dough ball on your baking sheet and press with a spoon or other flat-ish object to flatten them out. They'll puff up during baking.
Bake each batch for about 12 minutes. When done, let the cookies cool for about 10 minutes before moving to a cooling rack to finish cooling.
