I've always had a thing for banana nut muffins, but not until I cut out all highly processed food did I realize that the standard muffin is kind of like a cupcake minus the icing. I've cut out the refined sugar and used whole-wheat flour for this delicious banana nut muffin recipe.
Preheat the oven to 350 degrees F. Line a muffin pan with paper or silicone liners and set aside.
In a large bowl whisk together the flour, baking soda, salt and baking powder. Make a well (hole) in the center of the flour mixture and drop in the eggs, butter, and syrup. Mix with a fork until it just comes together and set aside.
In a small bowl mash the two bananas together with the back of a fork. Carefully fold the bananas and walnuts (if using) into the muffin batter and distribute evenly into the 12 muffin cups (or 36 mini muffin cups). Bake until they begin to brown on top and a toothpick comes clean when inserted in the center, about 20 to 22 minutes for regular sized muffins or 12 to 14 minutes for mini muffins.
