Add the sour cream, and eggs, and mix until the mixture is well combined.
Add ½ of the orange juice, ½ of the flour, and baking powder, and mix it until almost combined.
Add the other half of the flour and orange juice and mix until just combined.
Pour the cake batter into the prepared loaf pan and spread it with an offset spatula. Bake in a 180c (350f) oven for about 45-50 minutes (depending on the oven) or until a toothpick inserted into the cake comes out clean.
Make the orange glaze
In a medium-sized mixing bowl, add the powdered sugar, orange juice, kosher salt, and yogurt. Mix with a spoon or a mini whisk until the mixture is smooth and silky.
Top the cake with the glaze and let it sit for a few minutes before serving. Enjoy!
Notes
Use room temperature ingredients. It is important that you use room-temperature ingredients like eggs and butter. This step ensures that your mixture mixes into a homogenous mixture and bakes perfectly.
Creaming the butter and sugar together until light and fluffy is essential for a tender crumb in your pound cake. Take your time with this step for the best results.
Use fresh oranges! the key to a flavorful orange pound cake is using fresh oranges. Zesting and juicing the oranges yourself will give the cake a vibrant citrus taste.
Measure your flour correctly! When measuring your flour, avoid scooping it with a measuring cup. Instead, stir the flour with a spoon to create as many air pockets as possible, and spoon it into your measuring cup. Finally, level it with a back of a knife.
Don’t overmix the batter, you don’t want to develop the gluten in the flour. This step ensures you have a moist cake and not a dense and dry cake.
Line your baking pan with parchment paper! This step helps the cake to bake evenly, and it makes sure that your loaf cake will release easily from the pan.
Be patient! I know it’s extremely tempting to frost this cake as it is pulled out of the oven, but let the cake cool for at least 1 hour so it will be more firm and won’t crumble up.
