Preheat your oven to 350°F (175°C).

Grease a standard loaf pan or line with parchment paper.

In a large mixing bowl, whisk together the rolled oats, flour, baking powder, granulated sugar, cinnamon, and a pinch of salt.

In another bowl, combine the applesauce, vegetable oil, Greek yogurt, and eggs, whisking until smooth.

Pour the wet mixture into the dry ingredients and stir gently until just combined.

Carefully pour the batter into your prepared loaf pan.

Place in the oven and bake for 45-55 minutes, until a toothpick comes out clean.

Let the bread cool in the pan for about 10 minutes before transferring to a wire rack.

Mix powdered sugar, milk, and vanilla extract to prepare the glaze.

Once cooled, drizzle the glaze generously over the top.
