In a small bowl, mix ground flaxseed and water.
Set aside for 8–10 minutes until it thickens.
Lightly grease a microwave‑safe bowl with a little oil or spray.
In a blender or food processor, add: Banana, oat flour, yoghurt, protein powder (if using), vanilla, cinnamon, baking powder, salt and the flax “egg”.
Blend until smooth.
If the mixture is very thick, add 1–2 Tbsp milk or milk alternative and blend again. You’re aiming for a thick, spoonable batter.
Pour the batter into the prepared bowl.
Microwave on HIGH for about 90 seconds.
If it’s still very wet, microwave in 30‑second bursts until just set.
It should be soft and cake‑like, not dry.
Let it sit for 1–2 minutes to cool slightly.
Top with sliced banana or berries, a drizzle of maple syrup or honey, a spoon of yoghurt or nut butter, and a few dark chocolate chips if you like.
