What is best than take some time to bake sweets on a saturday. Staying home, mixing and baking. I had some leftovers of frozen blueberries. I have tried some once on the morning of Christmas Day with pancakes. Were delicious. And these muffins are also very yummii. Soft and fluffy. I have mixed 150 g flour, 50 g golden caster sugar, 1 teaspoon baking powder with a pinch of salt in a mixing bowl. Then mix in 1 beaten egg and 50 ml vegetable oil, and 100 ml milk. Then add the blueberries. Pour the batter into the muffin tins and bake the muffins in a pre-heated 200 C oven for 25 minutes. Cool and enjoy with a cup of hot coffee.
