Wheat Bran Banana Muffin

Preheat the oven to 160 °C (top and bottom heat) and line a muffin tin with paper cases.

Put the egg, oil, brown sugar, vanilla sugar and the mashed banana into a bowl and beat until frothy.

In a second bowl, mix the flour, salt, baker's ammonia and wheat bran well.

Gently fold the flour mixture into the egg mixture just until no dry flour is visible.

Divide the batter evenly among the muffin cases (about two-thirds to three-quarters full).

Bake in the preheated oven for about 20–25 minutes until the muffins are golden brown.

Let the muffins rest in the tin for 5 minutes, then remove them from the cases and allow them to cool completely on a wire rack.
