Preheat the oven to 325℉. Grease a 12-cup bundt pan.
In a large bowl, whisk flour, sugar, baking soda, baking powder, cinnamon and salt.
In a separate bowl, mix applesauce, yogurt, egg, oil vanilla (and tart cherry concentrate if using). Add to dry ingredients and stir until just combined.
Pour into prepared pan.
Bake for 50-60 minutes, or until toothpick inserted in center comes out clean. Mine have consistently been done at 48-50 minutes.
Cool 15-30 minutes or longer. I let mine cool for an hour to avoid any disasters! Before unmolding, run a plastic knife around the center circle to loosen it a bit.
To store cake, allow it to cool completely. Wrap tightly in plastic wrap and store at room temperature up to 2 days. This flavorful cake may be stored in the fridge for up to one week or frozen up to 3 months. Defrost at room temperature then warm gently in the microwave at 50% power until desired temperature has been reached.
