The recipe started as a loaf, but now I use it for muffins instead, as it's more practical for school lunches.
Put flour, baking powder, bicarb, nutmeg and sugar in a large bowl. In a jug put egg, buttermilk and have melted butter ready.
(I don't put the butter in with the other wet ingredients to keep it warm and fully melted.)
Add buttermilk/egg and melted butter to the flour mixture, and stir in gently. When almost combined, add blueberries and continue to stir until everything is just combined.
Spoon into muffin pans and cook at 190 C for 15-20 minutes (my smaller ones took 15 mins, and the bigger ones took 20 mins).
I had about 4 tablespoons of mixture left over and didn't have room for another muffin pan in the oven, so I oiled my mini quiche dish and made a little muffin cake instead. I sprinkled some extra demarara on the top and we shared a mini cake for dessert.
2 cups (300 g ) plain flour

small grating of nutmeg
1 cup (220 g) demarara sugar
