This recipe was adapted from a recipe in A Taste of Oregon. It went down well with my new housemates! To stop the mixture from curdling, make sure that all your ingredients are at room temperature before you start cooking.
Beat together 1/4 cup margerine and 1/3 cup sugar until well combined and fluffy-looking. Beat in 1 egg until well combined. Sift together 1 1/4 cup flour, 1 1/4 tsp baking powder, 1/4 tsp salt, 1/4 tsp nutmeg and 1/2 tsp cinnamon, then add to the wet mixture and combine. Slowly mix in 1/3 cup milk then fold in 1 200g pack of blueberries. If using paper cupcake cases, grease them with a little margerine (silicone cases won’t need greasing) and fill almost to the top with the mixture. Bake at 220°C for 5 minutes to create a rounded muffin-top, then turn the oven down to 180°C and bake for a further 15-20 minutes, or until a knife comes out of the centre of a muffin clean. The muffins will keep for several days in an airtight container.
