For the apples: Heat the honey in a small pan over medium heat. Add apples and apple pie spice to pan and, making sure they're well-coated with honey, cook until soft. Chill 1-2 hours or overnight.
For the yogurt: Measure out yogurt into a large bowl. If using plain yogurt, add sweetener of choice (such as Stevia, sugar, honey, etc.) and vanilla extract. Whip ingredients together until thoroughly combined.
Assemble the parfaits: In a tall glass, mason jar, or any bowl you have on hand, layer 1/2 cup yogurt, 1/4 cup apple mixture, and a sprinkle of granola. Repeat for remaining layer, and for other parfait.
Notes
Cook time includes chilling time, but actual assembly of parfaits only takes around 5 minutes.
