Preheat your oven to 350°F (175°C). This ensures that your banana bread will bake evenly throughout.
Grease your loaf pan with a little coconut oil or line it with parchment paper for easy removal after baking.
In a large mixing bowl, whisk together the whole wheat flour, baking soda, baking powder, salt, ground cinnamon, and ground nutmeg until well combined.
In a separate bowl, mix the melted coconut oil and coconut sugar together until well blended. Then add the Greek yogurt, beaten eggs, and vanilla extract, stirring until smooth.
Add the mashed bananas to the wet mixture and stir until fully incorporated.
Pour the wet ingredients into the dry ingredients. Gently fold the mixture together using a rubber spatula until just combined. Be careful not to overmix!
Gently fold in the raspberries and mini chocolate chips, if using, ensuring they are evenly distributed throughout the batter.
Transfer the batter to the prepared loaf pan, smoothing the top with a spatula.
Place the loaf pan in the preheated oven and bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, remove the banana bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely before slicing. Enjoy your Healthy Raspberry Chocolate Chip Banana Bread warm or at room temperature!
