Preheat your oven to 375°F (190°C) and grease an 8-inch square baking pan with coconut oil or non-stick spray.

In a large mixing bowl, combine the unsweetened coconut flakes, chopped walnuts, chia seeds, cinnamon, baking soda, and salt, stirring until well blended.

In another bowl, whisk the large eggs and unsweetened nut milk until frothy, then mix in the melted coconut oil and mashed banana until smooth.

Pour the wet mixture into the dry ingredients and gently fold everything together until just combined. Add the diced strawberries last and fold them in.

Pour the mixture into the prepared baking pan, smoothing the top. Bake in the preheated oven for about 40 minutes until the top is firm and golden.

Allow the bake to cool in the pan for about 10 minutes, then slice into squares and serve warm.
