I made these apple crumble muffins for the first time yesterday and they are absolutely delicious! The mix is moist therefore the muffins are fluffy and light. The crumble topping adds that extra flavour zing of deliciousness! Thanks so much for sharing your recipes.

These apple muffins are simple, budget-friendly and guaranteed to disappear fast (especially if you’ve got hungry kids hovering around the kitchen!). The combination of soft sponge, tart bursts of grated apple and the signature crunchy crumble topping makes them a real family favourite.
Unlike the giant Costco apple crumble muffins or fancy bakery versions, these are everyday muffins that anyone can make. You don’t need special equipment, just a bowl and a spoon—or your Thermomix if that’s your style.
This recipe is based on the same no-fuss, one-bowl approach I use in so many of my most popular bakes (like my Blueberry Muffins and Banana Bread), with the added bonus of that irresistible oat topping.

Muffin Ingredients
You only need a handful of simple ingredients to make these easy apple streusel muffins:
- Cinnamon – brings that warm, cosy apple crumble flavour we all love.
- Apples – no need to peel; the skin adds nutrients and texture. Use Granny Smith apples for tartness, or sweeter apples like Pink Lady, Honeycrisp or Fuji if you prefer.
- Rolled oats – make sure you use old-fashioned oats (not quick oats) to get that crunchy crumble texture.
- Vegetable oil – keeps the muffins soft and moist, plus saves you creaming butter and sugar.
Variations
Here are a few fun twists you can try with this recipe:
- Vegan Apple Crumble Muffins – replace the egg with a flax egg and use dairy-free milk and butter.
- Gluten-Free Apple Crumble Muffins – swap self-raising flour for a gluten-free blend and use GF oats.
- Nutty Apple Muffins – add a handful of chopped walnuts or pecans to the crumble topping for extra crunch.
- Apple & Berry Crumble Muffins – stir through a handful of blueberries, raspberries or blackberries with the grated apple.

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
- Step 1: In a large bowl, mix together all the muffin ingredients (except the crumble) until just combined. Don’t overmix.
- Step 2: Spoon into muffin cases, filling ⅔ full.

- Step 4: Bake 20 minutes or until golden and cooked through. Cool in tin for 5 minutes before transferring to a wire rack.
Top Tip
Don’t overmix the muffin batter—this keeps your muffins soft and fluffy instead of dense and heavy.
Recipe Tips
- Apple skin on – grate with skin for added fibre and colour.
- 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.
- Testing for doneness – insert a skewer or toothpick into the center of a muffin; if it comes out clean (or with just a few moist crumbs), they’re ready. If there’s wet batter, pop them back in for a couple more minutes.
- 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.
