These delicious one-bowl banana blueberry chocolate chip muffins are a healthified version of the classic with no oil or refined sugar.
Preheat oven to 375 degrees F and line muffin tin with 12 liners.
In a large mixing bowl, whisk together flour, baking powder, cinnamon, and salt.
Make a well in the center of the dry ingredients and add in mashed bananas, Greek yogurt or sour cream, maple syrup, eggs, and vanilla extract. Whisk together the wet ingredients in the center until completely combined.
Switching to a spatula, fold the dry ingredients into the wet ingredients just until incorporated. Fold in chocolate chips and blueberries.
Divide the dough between the 12 muffin liners and bake for 23 - 25 minutes or until golden brown on top and a toothpick comes out of the center of a middle muffin clean.
Sprinkle with a little bit of chunky salt (optional) and serve warm or at room temperature.
