Preheat the oven to 220°C fan/240°C conventional. Line a 6-cup jumbo muffin tin (or 12-cup baking tin) with liners.
In a large bowl, whisk the flour, sugar, baking powder and cinnamon together to combine. Set aside.
300 grams Self raising flour, 200 grams Brown sugar, 1 teaspoon Baking powder, 2 teaspoons Ground cinnamon
In a separate bowl, whisk the oil, eggs, milk and pumpkin puree together.
150 grams Vegetable oil, 2 medium Eggs, 100 millilitres Milk, 150 grams Canned pumpkin puree
Pour the wet ingredients into the dry and gently fold until the mixture is just combined. Be extra careful not to overmix at this stage, a lumpy mixture with lots of air bubbles is what you're looking for.
Fill the muffin liners half way with the mixture. Add a heaped teaspoon of Biscoff spread into the middle of each and spoon the remaining mixture on top. Set aside for now.
