Ingredients

Yes—cookies for breakfast! These banana oatcakes are naturally vegan, dairy-free, and gluten-free when you use certified gluten-free oats. The base is simply rolled oats and optional ground flaxseeds for extra fiber, combined with mashed banana, a bit of coconut oil, and any add-ins you like such as dark chocolate chips, raisins, or chopped dates. They freeze and reheat beautifully, making them ideal for meal prep.

Serving suggestions

These oatcakes are great warm from the oven or reheated in a toaster oven until crisp on top. Make a batch ahead and freeze them flat in a zip-top bag for easy grab-and-go breakfasts or school snacks. They taste even better the next day once the flavors have melded—reheat briefly to restore a pleasant crunch.

Servings: 12 oatcakes

Prep Time: 15 mins • Cook Time: 25 mins • Total Time: 40 mins

Ingredients

  • 3 cups (9.5 oz / 240 g) rolled oats (not quick-cooking or instant)
  • ¾ teaspoon fine sea salt

  • ¾ cup (3 oz) chopped walnuts or pecans (optional)

  • ¼ cup coconut oil, melted (or a neutral vegetable or nut oil)
  • Optional add-ins: chopped dark chocolate, chocolate chips, raisins, or chopped dates

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. In a large bowl, mix the oats, salt, cinnamon, nuts (if using), and ground flaxseeds (if using).
  3. Add the banana puree, melted coconut oil, and any optional add-ins. Stir until combined. Let the batter rest 5 minutes so the oats soften and the mixture thickens slightly.

  5. Bake 22–25 minutes, or until the edges and tops are light golden. Cool completely before storing. Refrigerate up to 1 week or freeze up to 3 months. Reheat in a toaster oven until lightly crisp on top.

Notes

Storage: Once cooled, store oatcakes in an airtight container in the refrigerator for up to 1 week or freeze for up to 3 months. Reheat in an oven or toaster oven to restore a crisp top.
