Ingredients

• 2 cups (200 g) old-fashioned rolled oats (or quick oats)
• 1 cup (240 ml) milk of choice
• 1 large banana, well mashed (about 1/2 cup)
• 1 medium apple, finely chopped (peel if you prefer)
• 3 large eggs
• 1/2 cup (60 g) walnuts, chopped
• 2 tbsp melted coconut oil or butter (optional, for moisture)
• 1 tsp baking powder
• 1 tsp ground cinnamon
• 1 tsp vanilla extract
• Pinch of fine salt

Optional add-ins: 1/4 cup raisins or blueberries, 1–2 tbsp chia or flaxseed, or 1–2 tbsp maple syrup/honey if you prefer sweeter (still minimal sugar).

Instructions

1. Prep the pan: Heat oven to 350°F / 175°C. Grease an 8×8-inch (20×20 cm) baking dish or line with parchment.
2. Mix wet: In a large bowl whisk the eggs, milk, mashed banana, vanilla, coconut oil/butter, and salt until smooth.
3. Add dry: Stir in oats, baking powder, and cinnamon. Fold in chopped apple and walnuts (plus any add-ins).
4. Pour & bake: Spread mixture evenly in the dish. Bake for 30–35 minutes, until set in the center and golden on top.
5. Cool & slice: Rest 10 minutes, then slice into squares. Serve warm or at room temperature.

Tips & Variations

• For firmer bars: Add +1/2 cup oats or bake a few minutes longer.
• Dairy-free: Use oat/almond milk and coconut oil.
• Higher protein: Stir in 2 tbsp peanut butter or a scoop of unflavored/vanilla protein powder and an extra splash of milk.
• Kid-friendly: Press a few chocolate chips on top before baking.
