Add all of your dry ingredients (white whole wheat flour, chia seeds, baking soda, salt, and 1 tbsp of cinnamon) to a large bowl. Combine flour mixture by whisking for about 30 seconds until thoroughly combined.
Mash bananas really well, and then add all of your wet ingredients (mashed banana, eggs, honey, Greek yogurt, oil, and vanilla extract) to a medium bowl. Whisk the ingredients together for 30-60 seconds until thoroughly combined.
Add your banana mixture to the large mixing bowl with the flour mixture. Stir gently until thoroughly combined without over-mixing.
Pour batter into a greased non-stick metal loaf pan (or lined with parchment paper) or silicone loaf pan. Top with brown sugar cinnamon topping. *Note: metal loaf pans typically cook more evenly than silicone loaf pans. Use a 9x5 inch loaf pan.
Bake for 45-50 minutes in a metal pan, 40-45 minutes in a silicone pan, or until a toothpick comes out clean. Note: baking time may differ depending on your oven, so start keeping an eye on it around the 35-40 minute mark.
Serve warm and enjoy!
Notes
Metal loaf pans typically cook more evenly than silicone loaf pans, so keep that in mind if you choose to use a silicone loaf pan. Use a 9x5 inch loaf pan.
Make sure to use very ripe bananas for a moist, perfectly sweet banana bread. Underripe bananas will produce a less sweet, more dry banana bread.
Cook time will vary based on your oven and pan. Be sure to start checking on your banana bread when it gets close to the end of the cooking time and test for doneness.
