1Whisk the oats, applesauce, milk, egg, vanilla and butter together.
2Place the sugar, flour, baking powder, baking soda, cinnamon, nutmeg, ginger and salt in a large bowl and stir to combine.
3Add the oat mixture to the dry ingredients and stir until just combined, then fold in the apple.
4Insert the wire rack in the bottom position. Set the oven to Bake, Convection, 330°F, for 20 minutes and press Start to preheat. Meanwhile, continue to the next step.
5Line 2 x standard 6-cup muffin pans with paper liners. Divide the batter evenly among the liners.
6Once preheated, place one of the pans in the oven and cook for 20 minutes. Halfway through cooking, rotate the pan and continue cooking.
7The muffins are ready when a skewer inserted into the center comes out clean. If not, cook them a little longer.
Tip: Don’t insert the skewer into any of the cracks as this will give an inaccurate reading.
8Stand in the pan for 10 minutes, then transfer to a wire rack to cool. Repeat with the remaining muffins.
9Muffins will keep in an airtight container for up to 3 days at room temperature or frozen for up to 3 months.
