Muffins in the air fryer

I make muffins in the air fryer for breakfast quite often. These are lovely but note they do NOT last long - I bake them, we eat them, and it's done....

100g of dry ingredients. Usually a mix of about 65g self raising flour then the rest a mix of wholemeal, oats and almond meal. + 1 tsp baking powder and a pinch of salt.

1 very ripe mashed banana.
1 egg
3 tablespoons of wet ingredients - I usually go with 1 honey/syrup, 1 generous of plain yoghurt and 1 stingy of oil. + teaspoon vanilla essence.

Mix all together then into individual ramekins or cases (makes three) topped with a walnut or pecan nut and a sprinkle of brown sugar. Bake in air fryer at 180 for 12-14 minutes (depends on your air fryer - mine runs hot).
