♡ Why You Will Love this Orange Olive Oil Cake 🍊

Wholesome ingredients. This tea cake is a bit more guilt-free than traditional cakes, as it uses extra-virgin olive oil, raw pistachio nuts and a whole orange. Plus, it only contains 8 ingredients!
Incredibly moist. The crumb is exceptionally soft and fluffy, thanks to the olive oil, and orange puree.
Super easy to make. There are easy-to-follow steps and no electric mixer required.
Not too sweet. The cake itself isn't too sweet which makes it perfect to pair with a cup of coffee or tea. Most of the sweetness will come from the thick icing.

For more delightful cakes to enjoy with your morning coffee or afternoon tea, try my lemon poppy seed yogurt loaf cake (readers favorite), blueberry buckle cake, and raspberry almond cake next!

Ingredient Notes

Here are some notes about all the ingredients used in this orange pistachio cake. Quantities and full instructions are in the recipe card below!

Pistachio Orange Olive Oil Cake

Pistachio Nuts - You can use roasted or raw pistachios. I didn't find a huge difference in flavor or texture between roasted or raw.
Navel Orange - I'm using a navel orange, which is seedless, but you can use any kind. We'll be using the zest of 2 whole oranges, and blending 1 whole orange for the cake.
All-Purpose Flour - I always recommend using a kitchen scale to measure your flour with for best results. Adding too much flour can make your cake dry and dense.
Sugar - We are using white granulated sugar. The cake is not too sweet, so refrain from cutting the amount of sugar as it will result in a dry cake.
Extra-Virgin Olive Oil - Makes the cake SO moist and adds a subtle fruity flavor! You can also use light olive oil.
Eggs - Adds structure and helps emulsify the batter.
Baking Powder - Helps the cake rise and creates a moist crumb.
Salt - Enhances all the flavors.

Fresh Orange Glaze

Powdered Sugar - Also known as icing sugar or confectioners sugar.
Orange Juice + Orange Zest - I'm using a combination of some orange zest and freshly squeezed orange juice.

Ingredient Substitutions

Pistachio Nuts - I used raw pistachios, but you can use pre-roasted pistachios. You can also replace with pecans, roasted almonds or omit completely if you have nut allergies or do not have any on-hand.

Extra-Virgin Olive Oil - You can use light olive oil or a neutral oil such as avocado, canola, vegetable, grapeseed or refined coconut oil.

Pistachio Orange Olive Oil Cake topped with an orange glaze, is made with a whole orange and extra-virgin olive oil. A slice of Pistachio Orange Olive Oil Cake is on a small dessert plate.

⭐️ Expert Tips

Use a kitchen scale to weigh all your ingredients. Baking in grams, rather than volume, is the best and most accurate way to bake! All my recipes include gram conversions based on King Arthur's Weight Chart.

If you are not using a kitchen scale, measure your flour correctly. Fluff and aerate your flour first, then spoon into your measuring cup and finally level off with the back of a butter knife. Do not pack it in as it will add too much flour.

Sift your dry ingredients. Sifting the dry ingredients before adding to your wet ingredients will ensure a smooth batter.

Do not overmix. As always, refrain from over mixing the batter as it will overwork the gluten, resulting in a tough cake.
