Thermomix Method
Preheat oven to 190 degrees celsius (fan-forced). Line a 12-hole muffin tray with muffin cases and set aside.
Place the chopped apples into the Thermomix bowl. Grate for 10 seconds on Speed 8. Scrape down the sides of the bowl.
Add the remaining muffin base ingredients (not the crumble ingredients) into the Thermomix bowl and mix for 5 seconds on Speed 5. Scrape down the sides of the bowl and repeat for a further 5 seconds.
Divide the mixture between the prepared muffin holes (filling to ⅔ full).

RECIPE NOTES & TIPS
Apple skin on – grate with skin for added fibre and colour.
Don’t overmix the muffin batter—this keeps your muffins soft and fluffy instead of dense and heavy.
Room temperature ingredients – helps the batter mix evenly.
Muffin height – fill cases ⅔ full and bake at a high temp (190°C) to get a nice rise.
Storage – keep in an airtight container at room temp for 3 days.
Freezer friendly – freeze in an airtight bag/container for up to 3 months.
Lunch box friendly – pack frozen into lunch boxes; they’ll thaw by recess.
Optional drizzle – add a thin vanilla icing drizzle if serving as dessert.
Crumble texture – always use rolled oats, not quick oats, for best results.
