Why You’ll Love This Recipe

  • Healthy Ingredients: Made with oats, ripe bananas, and other wholesome ingredients.
  • Versatile: Perfect for breakfast or as a snack, and great for meal prep.
  • Kid-Friendly: Naturally sweetened and packed with nutrients.
  • Quick Preparation: Minimal hands-on time means it’s easy to whip up.
  • No Baking Skills Required: Simple steps make this a stress-free baking experience.

Ingredients

  • 2 cups (200 g) rolled oats
  • 4 ripe bananas, mashed
  • 1/2 cup (120 ml) unsweetened applesauce
  • 1/2 cup (120 ml) milk (or plant-based milk)
  • 1/4 cup (60 ml) honey or maple syrup (optional, for extra sweetness)
  • 2 teaspoons baking powder
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (80 g) raisins or chopped nuts (optional)

Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8 inch (20×20 cm) baking dish or line it with parchment paper for easy removal.

  2. In a large mixing bowl, combine the rolled oats, baking powder, cinnamon, and salt. Mix well to combine.

  3. In another bowl, mash the ripe bananas until smooth. Add in the applesauce and milk, mixing them together thoroughly. If you’re using honey or maple syrup for extra sweetness, add it now.

  4. Pour the wet ingredients into the bowl with the dry ingredients. Stir until everything is well combined and you have a thick batter. Add in the raisins or nuts if you choose to include them.

  5. Spread the batter evenly in the prepared baking dish. It will be quite thick, so you may need to use a spatula to smooth the top.

  6. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

  7. Once baked, allow the oatmeal cake to cool in the dish for about 10 minutes before slicing into squares.

Pro Tips

  • Use very ripe bananas for the best flavor and sweetness; the darker the skins, the better!
  • For a richer flavor, consider adding some vanilla extract or a pinch of nutmeg.
  • Store in an airtight container to keep the cake moist; it also freezes well for up to a month.

Common Mistakes

  • Don’t skip the baking powder; it’s essential for giving the cake some lift.
  • Make sure your bananas are completely mashed; this ensures even sweetness and moisture.
  • Overbaking can dry it out, so keep an eye on it — check a few minutes before the recommended time.

Variations

  • Substitute pumpkin puree for applesauce for a seasonal twist.
  • Add dark chocolate chips for a treat that feels indulgent but still healthy.
  • For a nut-free option, omit the nuts and add more dried fruit, like cranberries or apricots.

Serving Suggestions

This oatmeal cake is great on its own, but you can also serve it with a dollop of yogurt or a drizzle of honey for an extra treat.

Storage Instructions

Store any leftovers in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
