How to make
Mix the sugar and eggs with a mixer, add the oil, sifted flour with baking powder and continue mixing.
Once a homogeneous mixture for the muffin batter is obtained, add the walnuts and grated apples and mix with a wooden spoon.
Pour the mixture into molds and bake the apple muffins at 360°F (180°C).
Once the apple walnut muffins are fully baked, sprinkle them with powdered sugar.
