Ingredients
Method
- Preheat the oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment. Beat butter and sugar 3 minutes until fluffy.
- Add eggs one at a time, then mix in orange zest, 3 tbsp orange juice, and vanilla.
- Whisk flour, baking powder, and salt. Alternate adding flour and sour cream to the butter mixture, mixing just until combined.
- Pour into the pan, bake 55 to 65 minutes until a toothpick has moist crumbs. Cool 15 minutes in the pan, then lift out to cool completely.
- Whisk powdered sugar, 2 to 3 tbsp orange juice, and ½ tsp zest. Pour over the cooled cake. Slice and serve once the glaze sets.
Notes
The cake tastes even better the next day. If making it ahead, skip the glaze and add it just before serving. Room temperature ingredients are key for a smooth batter.
