Preheat your oven to 350F or 175C. Add the sugar, milk, peanut butter and apple sauce to a bowl and mix until combined.
Now to a sifter add 1/2 cup of half of the flour and then add the baking powder, cardamom, cinnamon and add the rest of the flour on top. Sift the flour into the bowl of wet ingredients and mix until well combined. Be sure to not over mix the dough cause this will cause the cookies to become gummy.
Now with an ice cream scoop (or spoon) even sized balls onto a baking tray covered with parchment paper. Place into your preheated oven and after about 6 minutes take a fork and mash press it on top of the cookies to flatten it out a bit.
After approximately 15 minutes (depending on your oven and how thick you made your cookies) your cookies are done!
