Mash the plantain in a shallow bowl, then whisk in the egg, vanilla, sugar and oat milk. Mix the flour, cinnamon and baking powder in a separate bowl. Mix the wet ingredients into the dry until combined – don’t worry if it’s a little lumpy.

Heat a little butter in a frying pan. Pour ladlefuls of the batter into the pan and cook for 2-3 mins on each side until golden brown. Repeat for the rest of the mixture.

When all the pancakes are cooked, set aside on a plate and keep warm in a low oven if needed. For the topping, toast the walnuts in the pan, then pour in the milk and honey. Mix for a few mins until the nuts are sticky and coated. Spoon over the top of the pancakes, with a dusting of icing sugar to serve.
