Preheat Oven: Set your oven to 350°F (175°C).
Prepare Gelatin Egg Substitute: In a small bowl, mix 1 tablespoon of gelatin with 3 tablespoons of warm water. Stir well until the gelatin dissolves completely.
Combine Dry Ingredients: In a large mixing bowl, whisk together the almond flour, coconut flour, baking soda, and sea salt until well combined.
Add Wet Ingredients: To the dry mixture, add the homemade yogurt (or probiotic mixture), melted coconut oil, honey, and the prepared gelatin mixture. Stir until all ingredients are thoroughly combined and a batter forms.
Transfer to Loaf Pan: Grease a loaf pan with coconut oil or line it with parchment paper. Pour the batter into the prepared pan, spreading it evenly.
Bake: Place the loaf pan in the preheated oven and bake for approximately 30-35 minutes, or until the bread is golden brown and a toothpick inserted into the center comes out clean.
Cool and Serve: Remove the bread from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing and serving.
