  • 2 large ripe bananas, mashed
  • 1/2 cup (120 ml) unsweetened applesauce
  • 1/4 cup (60 ml) pure maple syrup or honey
  • 1/4 cup (60 ml) unsweetened almond milk
  • 1 large egg (or flax egg for vegan option)
  • 1 tsp pure vanilla extract
  • 2 cups (200 g) old-fashioned rolled oats
  • 1/2 cup (60 g) vanilla or chocolate protein powder
  • 1/2 cup (60 g) chopped walnuts
  • 1/3 cup (60 g) dark chocolate chips
  • 1/4 cup (30 g) unsweetened shredded coconut (optional)
  • 1/2 tsp ground cinnamon
  • 1/4 tsp fine sea salt
  • 1 tsp baking powder

Instructions

Step 1
Preheat your oven to 350°F (175°C). Line an 8x8-inch (20x20 cm) baking pan with parchment paper.
Step 2
In a large bowl, mash the bananas thoroughly. Whisk in the applesauce, maple syrup, almond milk, egg, and vanilla extract until smooth.
Step 3
In a separate bowl, combine the oats, protein powder, walnuts, chocolate chips, coconut (if using), cinnamon, salt, and baking powder.
Step 4
Add the dry ingredients to the wet mixture. Stir until just combined.
Step 5
Pour the batter into the prepared pan and spread evenly. Top with extra chocolate chips and walnuts if desired.
Step 6
Bake for 25–28 minutes, or until golden and set. A toothpick inserted in the center should come out mostly clean.
Step 7
Cool completely in the pan. Lift out using the parchment, then slice into 12 bars.

Zusatztipps für die Zubereitung

To ensure the best texture, use a mixing bowl and whisk to blend the wet ingredients until completely smooth before folding in the dry mixture. Lining your 8x8-inch baking pan with parchment paper is essential for lifting the bars out easily after they have cooled completely.

Serviervorschläge

These bars pair beautifully with a hot cup of coffee for a cozy breakfast or a cold glass of almond milk for a post-workout snack. They can be enjoyed at room temperature, chilled from the fridge, or even slightly warmed in the microwave for a more indulgent treat.

Recipe FAQs

How do I store these oat bars?

Keep bars in an airtight container at room temperature for 3 days, refrigerate for up to 1 week, or freeze individually wrapped for longer storage.

Can I make these vegan?

Replace the egg with a flax egg—1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, rested for 5 minutes before adding to the batter.

What protein powder works best?

Vanilla or chocolate protein powder in whey or plant-based varieties both work. Choose unsweetened powder to control sweetness levels.

Why did my bars turn out dry?

Overbaking or using too much protein powder can cause dryness. Check at 25 minutes and remove when golden—the center should set while cooling.

Can I substitute the nuts?

Pecans, almonds, or cashews replace walnuts nicely. For nut-free versions, try pumpkin seeds or sunflower seeds for crunch.
