Preheat your oven to 325 degrees. Use the cooking spray to coat a doughnut pan (a muffin pan or bundt pan will work if you don’t have a doughnut pan).
In a large bowl, whisk the salt, baking soda and flour together.
In a medium bowl, mix the bananas, coconut oil, yogurt, agave syrup, vanilla and egg until smooth.
Add the two mixtures together and mix.
Pour the batter into a pastry bag (or resealable plastic bag with the corner cut out). Squeeze the batter into the doughnut pan, make sure that each indentation is around ¾ full. Sprinkle the walnuts on top and press them into the batter lightly.
Back for 14-16 minutes, or until golden and springs back when pressed. Remove from oven and place to the side for a few minutes. After they cool off for a few minutes, carefully turn them out onto a wire rack and let cool fully.
