Preheat oven to 350ºF, and line a muffin tin with paper liners.
In a medium bowl, sift together the flour, cornstarch, baking powder, baking soda, salt, spices and Apple Cider mix. Set aside.
In the bowl of a stand mixer fitted with a paddle attachment, cream the butter and sugars together on high until light and fluffy. Reduce speed to low and add the eggs, one at a time, until fully incorporated. Add the yogurt, applesauce, and vanilla and mix to combine.
With mixer set on low speed, slowly add in flour mixture and mix just until incorporated. Do not overmix! Stop mixer and scrape down sides and bottom of bowl, giving one last stir by hand to ensure everything's well blended.
Using an ice cream scooper or two large spoons, scoop batter into lined muffin cups about 3/4 full. Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Remove from the oven and allow to cool in the muffin tin for 5 minutes before transferring to a wire rack to cool completely.
