Preheat the oven to 180°C (350°F/ Gas 4). Combine all ingredients in a blender into a nice batter. Fill a piping bag with a tip approx. 1 cm (½ inch) in diameter. If you do not own one, you can also create balls using two tablespoons. Fill paper mini muffin cups with the batter. Place cups in the cavities in a mini muffin tray, if you do not own one, use two paper cups for strength. Bake until golden brown in hot oven for 22–25 minutes.
