This easy Passion Fruit Lemon Loaf Cake is a moist, sweet tart quick bread that has a wonderful citrus flavor profile with a deliciously unique twist thanks to the passion fruit glaze drizzled over the top.
Honestly, you could call this a lemon loaf cake or lemon bread, because they’re basically the same thing, right? It’s right along the lines of my favorite coconut lime glazed banana bread or double chocolate zucchini bread where it’s basically dessert masquerading in the form of a quick bread.
The moist, lemony cake has a tight crumb and a bright citrusy taste. But rather than pair it with a typical lemon glaze, I changed things up by going with a passion fruit glaze as part of Freaky Fruits Friday.
What Does Passion Fruit Taste Like?
I distinctly remember the first time I ever tasted passion fruit.
It was on an airplane flying to Hawaii when I was 5 or 6 years old. The airline served a popular Hawaiian beverage known as POG, which stands for Passion Orange Guava Juice, and I was immediately hooked.
I remember asking and trying to figure out what it was because it tasted so different from any other juice I had ever tasted, and it wasn’t until I was older that I really had any understanding of what passion fruit was.
Passion fruit has a very strong fruity, tart flavor that is very tropical. Most of my experience with passion fruit has been with drinks or creamy, custardy desserts.
They are round and purple-ish on the outside with a greenish-yellow pulp and dark seeds inside. The seeds are totally edible, even though they may truly be a little “freaky” looking when you first slice into the passion fruit, and I chose not to strain them out when making the glaze for this passion fruit lemon loaf cake.
It gives it a more distinct look than if you strained the passion fruit glaze to remove the seeds, which would then make this look like any other lemon loaf cake.
To use the passionfruit, just cut it in half with a sharp knife and scoop out the insides, seeds and all, to use in this, or any other recipe.
With passion fruit, a little goes a long way! The flavor is so strong that even though the amount of fruit you get from one passionfruit is tiny, it packs a big punch that pairs really well with other fruit and vegetable flavors like orange, guava, lemon, and more.
But it also helps balance out sweet or rich ingredients, much like any other citrus fruit, such as white or milk chocolate, heavy cream, or butter.
If you want to remove the seeds from the passion fruit before using it, this can be done by pressing the scooped insides of the passion fruit against a fine sieve to release the juices into a bowl.
How to Make Passion Fruit Lemon Loaf Cake
This simple passion fruit lemon loaf cake recipe is made by first whisking together eggs, sugar, sour cream, oil, lemon zest, lemon juice, and vanilla in a bowl. The sour cream gives a wonderful depth of flavor and texture to the cake, and the oil keeps it a little more moist than butter.
I find that there is no need for lemon extract when you use the lemon zest along with the lemon juice in the cake.
Whisk the dry ingredients together in a separate bowl, then stir everything together just until it is combined without overmixing. It’s completely normal for the batter to be a little on the lumpy side.
Bake the loaf for 50-55 minutes at 350 degrees F until a tested inserted in the center of the loaf comes out clean with just a few crumbs, then remove from the oven and cool before adding the glaze.
The passion fruit glaze is made by simply stirring the pulp and seeds of 2-3 passion fruit together in a bowl with 1 cup of powdered sugar. At first it will seem like there is not enough liquid to create a glaze, but the sugar will cause the passion fruit to release it’s juices and create a nice, fairly thick glaze.
If you prefer a thinner glaze, add a little milk, 1/2 teaspoon at a time, to thin to your desired consistency.
Pour over the cooled lemon loaf cake and let set for at least 15 minutes before slicing and serving.
Tips for Passion Fruit Lemon Loaf Cake
- Change up the flavor profile of this delicious loaf cake by switching out either the lemon or the passion fruit for blood oranges, which are another “freaky fruit” for a different flavor profile that would also be delicious and fun. You could even lay thin slices of blood orange across the top before baking for a beautiful design.
- Store the loaf in an airtight container for up to 5 days at room temperature. This loaf can also be frozen, but I would recommend waiting to glaze it until after it has been defrosted.
- The recipe doubles easily if you want to make another loaf to share or have for the next day, because in my experience, this is gone overnight.
