Preheat oven to 350 degrees F.
Line a cupcake pan with liners and set aside.
In a large bowl or stand mixer fitted with a whisk attachment, beat together the flour, baking powder, eggs, yogurt, and applesauce and mix until combined.
Beat in peanut butter, honey, and grated apple.
Add a 1/4 cup of batter to each cupcake liner and bake for 20-25 minutes, until toothpick comes clean when inserted into the center. Allow to cool in pan for a few minutes before transferring to a cooling rack.
Once pupcakes have cooled, beat heavy cream until light and fluffy, about 3-4 minutes.
Pipe whipped cream onto the cooled pupcakes and top with a dog biscuit. Serve shortly after frosting or store in the fridge or freeze them. Dogs should only be given one a day.
