Baked oats

If you're cooking them in the oven, heat it to 180C/160C fan/gas 4. Put the oats in a blender and pulse a few times until they start to resemble flour. Add the baking powder, chopped banana, maple syrup or honey, eggs and mixed spice or cinnamon, and whizz until smooth. Stir in the chocolate chips or berries.

If using an air-fryer rather than an oven, heat the air fryer to 180C for 4 mins. Lightly oil four heatproof ramekins, then divide the batter between them. Bake for 8-10 mins in the air-fryer or 20-25 mins in the oven until well-risen and the baked oats spring back when lightly pressed. Scatter with more chocolate chips or berries before serving, if you like.
