Get your oven ready at 350°F (175°C) and lightly grease an 8x4 inch loaf pan. A quick spray or a bit of butter works perfectly!
In a big bowl, whisk together your almond flour (or coconut flour), sugar-free sweetener, baking soda, and salt. Make sure there are no lumps for a smooth batter.
Now, pour in the beaten eggs, creamy Greek yogurt or sour cream, fragrant vanilla extract, and that wonderful banana extract. Stir everything until it's perfectly combined.
Gently fold in your chosen add-ins – crunchy walnuts or sweet sugar-free chocolate chips. Feel free to sprinkle a few extra on top for a pretty finish!
Pour the batter into your prepared loaf pan and loosely cover it with aluminum foil (this helps prevent over-browning). Pop it into the preheated oven for 45 minutes to 1 hour. If using almond flour, it can handle a little extra baking. If using coconut flour, bake until a toothpick comes out clean.
Once baked, let your amazing banana bread cool completely on a wire rack before carefully removing it from the pan and slicing. This ensures the best texture! Enjoy your guilt-free, delicious slice!
