Super soft moist orange cake made from an easy butter cake base. This cake has a bright, strong citrus flavor and a lovely fluffy texture.
We’ve got another one to add to the family! I flirted with the idea of an orange cake after making my lemon cake some two years ago but wanted to wait until that one had its moment. Then last year there was the banana cake and later on the cinnamon coffee cake. This year I have no real designs on any new everyday cakes so you’re getting orange! And it’s right in time for all those juicy in season navels.
This recipe is based on my everyday lemon cake with some differences, besides the obvious swapping of citruses: I have more orange juice in here (to accommodate the ph and make the flavor stronger) and a little bit more flour, to absorb that extra liquid. The mother recipe for all of my ‘everyday’ cakes is this everyday butter cake.
Butter: unsalted butter, cold is fine (we’re melting it).
Oranges: navel or cara cara. I haven’t tried this with blood oranges but you’d need a few more, the cake may also turn a tad green.
Sugar: fine granulated sugar for the batter. If you have organic granulated sugar (the granules are usually bigger) it’s better for the topping for more of a crisp, but fine is ok for the topping too.
Eggs: whole large eggs – they MUST be at room temperature or the batter will split when you add them.
Cake flour: made from a finer softer wheat than all purpose this will give you a more tender cake. You can make the cake with a mixture of all purpose and cornstarch (swapping two tablespoons of starch for flour), though it won’t be as tender.
Sour cream: full fat sour cream. In a pinch if you need to substitute, use a full fat greek yogurt or labneh.
Vanilla: pure vanilla extract or vanilla bean paste.
Salt: use fine sea salt. If using table salt, halve the amount.
Baking powder: to leaven the cake. Don’t confuse this with baking soda!
Bring the eggs to room temperature by placing them in a bowl of warm water. This is very important so the batter doesn’t split!
Preheat the oven and prepare a square pan: use a light colored pan so that the cake doesn’t get too dark. Line it with parchment paper to protect the cake from overbrowning, use some grease to get the paper to stick to the pan.
Zest the oranges over the sugar, then rub it in: this releases the oils and flavor.
Melt the butter then add it, the vanilla and salt to the bowl – whisk it well.
One by one, add the eggs: whisk VERY well between each addition.
When all the eggs are in you should have a smooth mix, it will be shiny.
-> If the eggs are cold the batter will split at this point. You can gently warm the bowl, place it over a pan of steaming water, to try to melt the bits of butter and then whisk well.
Sift in the cake flour and add the baking powder, once it’s halfway mixed add the sour cream.

Mix until the batter is smooth.
Pour it into the prepared pan and smooth it into one even layer.
Sprinkle granulated sugar on top, I like organic sugar here because the bigger granules give the topping more crunch.
Bake the cake until a cake tester inserted into the center comes out clean – depending on the pan size the bake time will vary: check it at 30 minutes and continue baking as needed.
Let cool in pan then serve!
Add-ins: mini chocolate chips (about ½ cup); white would be good, or if you are into chocolate/orange you might like semi-sweet. Poppyseeds would be good too (a few tablespoons) or some nuts (about ½ cup).
Toppings: My favorite way to make this cake is with the sugar topping which gives it a sparkly, crisp finish that crumbles as soon as it’s touched. If you’d like to do a glaze you can combine 130g or 1 cup powdered sugar with a few tablespoons of orange juice, milk or heavy cream. Don’t forget the pinch of salt and dash of vanilla.
You could also do a frosting; cream cheese would be great or a vanilla bean. Whipped cream, use my stabilized whipped cream recipe, would be great too.

This cake was everything I needed on the first day of February. I added 1/3 cup mini chocolate chips. Just like all the EBC’s this was stellar!
Hi Jen – I know you were looking forward to this so I’m glad it lived up to expectations!
This sunny, orange cake brightened up our cold January! Great orange flavor and easy to whip up without any special equipment.
aw so happy to hear it had that effect on these dreary days – thank you!
This came out really well with great orange flavor (my navel oranges were huge so there was a lot of zest). The ingredients list orange juice, but it doesn’t appear in the steps. I added it after the eggs and that seemed fine.
Hi Kim, so glad to hear it turned out well! also – fixed that step.
Delicious! I made it with poppy seeds, sooo good!
Oooh I love the poppy addition!
