Add all ingredients apart from the carrots and walnuts to a blender. Once blended, fold in the grated carrots and walnuts with a spoon
Equally, distribute the batter in the muffin liners in the muffin tray and shake the tray so the batter is evened out
Place in the oven and cook for 20-25 minutes (use a skewer to see if the muffins are cooked. If the skewer comes out dry then it is cooked)
Let the muffins cool down. Once it is cooling down, add the soft cheese to a bowl and mix with a hand mixer until soft. Then pour the maple syrup and vanilla and mix until it thickens.
With a tablespoon, top the muffins with the icing and add some chopped nuts on top.
