To make this Apple Banana Bread, start by preheating your oven to 350°F.
Line a standard loaf pan with parchment paper (or a silicone liner if you have one). You can lightly grease the pan with oil first to help the parchment stay in place.
Next, chop the apples into small pieces and set them aside. In a skillet over medium heat, add the avocado oil. Once hot, stir in the chopped apples along with 2 teaspoons of the cinnamon.
Sauté the apples for about 5 minutes, until softened and fragrant. Remove the pan from heat and let the apples cool slightly.
Now, in a blender, add the bananas, eggs, vanilla extract, cottage cheese, and maple syrup. Blend until completely smooth. Set the mixture aside.
In a large mixing bowl, whisk together the almond flour, baking soda, and the remaining cinnamon.
Pour the blended wet ingredients into the bowl with the dry ingredients and stir until everything is well combined and no clumps remain.
Pour half the batter into your prepared loaf pan and spread it into an even layer. Spoon half of the sautéed apple mixture over the top. Add the rest of the batter, then top with the remaining apples. Gently tap the pan on the counter to level everything out.
Transfer the loaf pan to the oven and bake for 55-60 minutes, or until a toothpick inserted into the center comes out clean. If the top starts browning too much, you can loosely cover the pan with foil after about 30 minutes.
Once baked, remove from the oven and let the bread cool completely in the pan before slicing. Enjoy!
