For The Muffins

• Self-raising flour - also known as self-rising flour. You can use store-bought self-raising flour or make your own using my homemade self-raising flour recipe.
• Vegetable oil - use a mild, unflavoured oil like vegetable or canola oil.
• Milk - I always recommend using full-fat milk in baking recipes for the best result, however if your preference is to use a skim or light milk, then that will also be fine to use.
• Egg - use a large egg (aprox 60g), it's best to have your egg and milk at room temperature.
• Caster Sugar - a finely granulated sugar which dissolves well when mixed with other ingredients.
• 2 Small Apples - grated - there's no need to peel them before grating. Choose an apple variety that holds its shape when cooked. I like to use Granny Smith apples, which have a little tartness to compliment the sweet crumble, but many other varieties, such as the sweeter Fuji or Pink Lady varieties, are suitable to use as well.

For The Crumble

• Plain flour - also known as all-purpose flour.
• Rolled oats - I've specified rolled oats rather than quick oats in this recipe as the larger oats give the crumble topping more texture.
• Brown sugar - you can use either regular light brown sugar or dark brown sugar.
• Butter - at room temperature. I recommend using real, salted or unsalted butter, rather than margarine or butter substitutes in baking recipes.
• Ground cinnamon - is a spice from the dried bark of the Cinnamomum tree which has been ground into a powder. Cinnamon is often paired with apple, and subtly enhances the flavour of these apple muffins with crumb topping.

Equipment Required

• Grater - or Thermomix (optional) - to grate the apples.
• Muffin tray and paper muffin cases - the paper cases make it easy to remove the apple crumble muffins from the tray, easier to pack in lunchboxes - and they look pretty too!
• Oven - I specify fan-forced oven temperatures in my recipes, so if you have a conventional oven, increase the temperature by between 10 and 20 degrees Celsius.

Step By Step Instructions

Once the apples are grated, it's a simple one-bowl mix for both the base muffin batter and the oaty crumble.

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method!

Step 1 - Grate The Apples And Mix

Preheat the oven, and line your muffin tray with paper muffin cases.

Grate the apples, and place in a large mixing bowl.

Add the self-raising flour, vegetable oil, milk, egg and caster sugar to the grated apple.

Mix the muffin base ingredients until just combined (don't over-mix or your muffins will be tough!).

Step 2 - Fill The Muffin Cases

Divide the mixture into the paper cases, filling each case to ⅔ full.

Step 3 - Make The Crumble Topping

Place the plain flour, rolled oats, brown sugar, butter and ground cinnamon in to a clean bowl.

Mix well until the ingredients are combined and you have a dry crumbly mixture.

Tip - I find it easiest to use my fingers to rub the crumble ingredients together.

Sprinkle the crumble mix evenly over the top of the unbaked muffins.

Step 4 - Bake

Bake in the oven until golden and crunchy on top and cooked through.

Allow to cool in the tin for 10 minutes before transferring to a wire rack to cool completely.

FAQs

Expert Tips

• Room temperature ingredients - make sure your 'wet' ingredients, such as milk, butter and eggs, are brought to room temperature before using them for best results. This helps them to combine more evenly with other ingredients, but also allows each ingredient to 'act' as it should - butter emulsifies better, egg yolks break down easier, and room temperature ingredients allow the baking process to start straight away when placed in the oven.
• Don't over mix your base ingredients, just mix gently until combined to keep them light and fluffy.
• Use paper muffin cases - not only do they look pretty, they also make it easier to remove the muffins from the muffin tray, and pack easier into school lunch boxes.
• You can add a sprinkle of rice grains to the bottom of the muffin tin holes (this stops the paper cases from getting greasy).
• Suggested variations - include drizzling a little thin vanilla icing over the top of the crumble for a decadent look or to serve as a dessert, or add a handful of sultanas or chopped dates, or even chopped walnuts or pecans for a nutty change.
• Storing & Freezing - these apple crumble muffins don't last long in my house! They can be stored in an airtight container at room temperature for up to 3 days (not in the fridge – or they’ll dry out). Alternatively, they can be frozen for up to 3 months - pop into a lunch box and they'll be thawed by lunchtime!
