Step 1

Preheat the oven to 400ºF/200ºC. Line a 12-hole muffin pan with paper cases.

Step 2

First, make the streusel topping: add all streusel ingredients except the melted butter to a bowl and mix. Add the melted butter and use your fingers to rub it all together into large crumbs. Set aside.

Step 3

In a large mixing bowl, whisk the flour, baking powder, sugar, cinnamon and salt.

Step 4

In a smaller bowl, whisk the eggs, milk, melted butter and vanilla together.

Step 5

Stir wet mixture into the dry mixture and gently mix to combine.

Step 6

Spoon the batter into the muffin cases to ¾ full. Sprinkle the tops of each one with the streusel mixture.

Step 7

Bake for 20-25 mins until the cinnamon muffins are risen and golden. Allow to cool on a wire rack.
