Preheat oven to 350°F (175°C) and grease a loaf pan.
In a bowl, whisk flour, sugar, baking powder, baking soda, and salt.
In another bowl, mix sourdough discard, eggs, melted butter, milk, and vanilla.
Combine wet and dry ingredients until just mixed. Do not overmix to keep the sourdough discard strawberry bread soft.
Gently fold in chopped strawberries.
Pour batter into prepared pan and smooth the top.
Bake for 50–60 minutes until golden and a toothpick comes out clean.
Cool completely on a rack.
Mix glaze ingredients until smooth and drizzle over the cooled bread.
