Set out dairy and eggs to come to room temperature. Place baking rack in the center of the oven and preheat to 350 degrees F. Liberally butter the sides of a 9 x 5-inch bread pan and set aside.

In a medium bowl, combine flour, baking soda, salt, sugar, and spices. Then, using the paddle attachment and lowest setting on a stand mixer, or a wooden spoon, lightly beat the butter, and then add eggs and yogurt, one at a time. Add vanilla. Fold mashed bananas in gently. Finally, add flour mixture in thirds and stir just until combined.

Spoon batter into prepared bread dish and cook 55 - 65 minutes, or until a wooden skewer comes out with just a few crumbs attached and the top is golden brown. Keep a close eye toward the end of cook time.

Cool 30 minutes before serving. If tightly covered, the bread will keep several days at room temperature.
