In way of preparation, put 20g of the Brown Sugar, and 5g of Cinnamon Powder in a small bowl and mix thoroughly
In a second bowl, peel 250g of exceedingly ripe bananas and squash them until they reach the consistency of baby food (a potato masher will do the trick)
Next, sift 250g of All Purpose Flour into a third bowl, then add 8g of Baking Powder, 2g of Salt and stir until entirely combined
Once that is out of the way, pre heat the oven to 220℃ (430°F, Fan 200°C, Gas Mark 7), and line a muffin tray with paper cake cups
Now, place 100g of Butter and the remaining 150g of Light Brown Sugar into a large mixing bowl, and beat together into a paste. Under no circumstances should you heat the Butter to make life ‘easier’
Add the 250g Squashed Banana, along with 100g of Eggs, 4g of Vanilla Extract, 80g of Milk and mix quickly until it becomes an ungainly, pulpy mess
Drop in the previously prepared bowl of Flour, Baking Powder and Salt, then stir with a rubber spatula until the whole thing resembles a thick porridge. This should take less than a minute, so be careful not to overdo it
Add 150g of Fresh Blueberries, and stir together until evenly distributed
Take the freshly made muffin mix, and fill each of the paper cups to the very top, piling it up as much as possible. Then, Sprinkle approximately 5 grams of the sugar and cinnamon prepared in step one over each muffin
Bake for 7 minutes at 220℃ (430°F, Fan 200°C. Then, without opening the oven, reduce the temperature to 180°C (350°F, Fan 160°C, Gas Mark 4) and bake for a further 20 minutes, or until an inserted skewer comes out clean
Once baked, immediately remove the muffins from the baking tray, and leave on a wire rack until cool
Test your creation alongside a cup of tea, and give yourself a pat on the back for not wasting bananas
