Apple Crumble Muffins

These are really good muffins. I cannot tell you how delicious these are.
They are really moist and stay soft for days (if they last that long)
If you love apple crumble then these are like a dessert in a cake.

Muffins are my favourites as they are effortless to make, the only fiddly part is making the crumble.
Here's the recipe and I recommend using sharp apples like Granny Smith's, the sourness really brings out the flavour.

 Topping:
60g caster sugar
90g plain flour ...
60g butter
Pinch of salt
(Rub ingredients together and set aside)

Muffin:
In Bowl A;
120g butter (melted)
120g light brown
sugar
2 eggs beaten
150g sour cream
(All in one bowl and mix to combine)

In Bowl B;
250g plain flour
2 tsp baking powder
1/2tsp bicarbonate of soda
1 tsp cinnamon powder
A pinch of salt
(In another bowl and sifted together)
100gm diced apple.
You can add raisins if you wish but I left them out because I don't like them.

Bowl B (dry ingredients) make a well and pour in Bowl A. Then in goes the fruits.
Mix about 10 times or until mixture is lumpy. Split mixture 3/4 full into muffin cases and spoon generous amount of crumble on each muffins. 
It's that simple!

 *Don't over mix it would make the muffins chewy and firm.
*Some flour is still visible but don't worry, it will all come together once in the oven.
Bake 180 for 20-25mins. Remember oven varies so test it with a skewer to see if it comes out clean.

 This recipe makes 12 - 14 muffins.

 You can use blueberries or other fruits and it will still taste amazing!
