Prep: Preheat your oven to 350°F (175°C) and lightly grease an 8×8 inch baking dish.
Mix Wet Ingredients: In a large bowl, whisk together the egg, ½ cup of Greek yogurt, and the unsweetened applesauce until smooth.
Combine: Fold in the rolled oats, diced apples, chopped nuts, and cinnamon. Stir until everything is evenly coated.
Pro tip: If the mixture seems too dry, add a splash of milk or water.
Bake: Pour the mixture into your prepared baking dish and spread it out evenly. Bake for 30–35 minutes, or until the top is golden brown and the oats have set.
Serve: Let it cool for 5 minutes. Slice into squares and top each serving with a generous dollop of the remaining Greek yogurt and an extra sprinkle of cinnamon or a drizzle of honey.
Customization Tips
Extra Texture: The photo shows what look like raisins or dried cranberries—feel free to toss a handful into the mix for a little extra chew.
Meal Prep: This stores beautifully in the fridge for up to 4 days. You can eat it cold or pop a square in the microwave for 30 seconds to revive that fresh-baked warmth.
