Allow any chilled items (banana – if smashed from frozen, milk, yogurt, eggs) to sit out until room temperature. By allowing them to warm from chill, they mix better for a smoother batter that will make fluffier pancakes.
Meanwhile start the tart cherry reduction. In a small saucepan, cook the tart cherry juice on medium high heat until it reduces by half (or even further if you want a thicker syrup). Add the maple syrup and whisk together. Set aside or in refrigerator to cool.
In a large mixing bowl, whisk together the dry ingredients: flour, baking powder, baking soda, salt, walnuts.
In the other large mixing bowl, whisk together the wet room temperature ingredients: yogurt, milk, smashed banana, maple syrup, eggs and vanilla first and then whisk in the oil last.
Make a well in the dry ingredients and then pour the wet ingredients into the dry ingredients using the rubber spatula to gently fold together from the bottom of the bowl until there are no dry spots. It will be a thick batter that may be a bit lumpy – and that is okay.
Allow the batter to sit for at least 5 minutes to rest.
On a medium stove setting, heat the nonstick pan. Once it is hot, make one pancake with the ¼ measuring cup. The first one is always a tester, so don’t waste the batter until you get this one done. Cook the pancakes until the edges start to look set and lightly bubble holes around the outside show up, then flip and cook on the other side another minute or two. After this tester one, make as many in batches as fit well in your pan, wiping out the pan with paper towels and re-adding pan spray or butter to melt for cooking.
Hold pancakes warm or eat immediately with thetart cherry-maple syrup. Enjoy!
