Ingredients

The ingredients for this easy passion fruit loaf can be divided into two groups:

• Dry ingredients: self-raising flour, caster sugar, salt.

• Wet ingredients: unsalted butter, eggs, sour cream, passion fruit and limes (lime juice).

Instructions

Before you start making this passionfruit cake, make sure the ingredients are at room temperature. Take the butter, eggs and soured cream out of the fridge at least an hour before.

Watch the video in the recipe card to see how I made this cake.

Start by creaming the sugar and the soft butter together, until the mixture is pale and fluffy. This should take about 3-4 minutes, using an electric mixer.

Next, add the beaten eggs. Do it gradually, adding only a little bit at a time, about a tablespoon. Keep whisking after each addition, and scrape the sides and the bottom of the bowl as needed.

Sift in half of the flour and salt and using a spatula, fold them gently. Add the soured cream, and fold until fully combined, followed by the remaining flour. Fold the ingredients until they are just combined and you have thick batter.

Hint: Do not overmix the cake batter. Folding the ingredients until they are just combined will ensure the light, fluffy and soft texture of the cake. Stop folding the cake batter as soon as the last ingredient you added (flour) is no longer visible.

Transfer the cake into prepared loaf tin and smooth the top with spoon or spatula. Bake in the oven for 1 hour, or until toothpick inserted in the middle comes out clean. Allow the cake to cool in the tin for about 10 minutes, then transfer it into a cooling rack.

Syrup and drizzle

While the cake is cooling, prepare the syrup and drizzle. Spoon out the passion fruit pulp into a sieve placed over a medium bowl or a jug and press it hard with the spoon or spatula to extract as much juice as possible.

Save about 2 tablespoons of the passion fruit seeds, and set them aside (you will use them later for the drizzle and topping). Juice the limes and add to the passion fruit juice.

Rinse the passion fruit seeds that you saved earlier under the running water. Try to discard as much of the pulp from the seeds as you can.

Use a skewer or a cake tester (toothpick will also work) to poke all over the top of the cooled cake with. Brush the cake with half of the passion fruit and lime juice mixture. Add the passion fruit seeds to the remaining half of the juice, and add the 60 g of caster sugar to it. Spread this syrup over the top of the cake.

You can serve the cake straight away, or allow it to sit for another 1-2 hours on the kitchen counter for the drizzle to set and soak more into the cake.

Hint: For the maximum crunch, allow the cake to sit for at least a couple of hours. The sugar from the syrup will create a deliciously crunchy topping along with the sugared passion fruit seeds.

Substitutions

• Caster sugar - Feel free to use white caster or granulated sugar instead (in the cake and in the syrup/ drizzle).
• Self-raising flour - This type of flour is commonly used for baking in the UK, and it already has raising agents added to it. If you don't have any self-raising flour, use plain flour (same amount), but add 1 ½ teaspoon of baking powder to it.
• Soured cream - Adding soured cream to cake batter creates wonderfully moist and tender crumb. You can also use yoghurt, buttermilk or even some coconut cream instead.
• Passion fruit - I recommend using fresh passion fruit in this recipe. But you can also use frozen passion fruit, or replace it with passion fruit puree, which is available to buy in most of the supermarkets (it may be without the seeds, but it will still taste delicious).
• Limes - Use lemons or lemon juice instead of limes.

Variations

This simple drizzle cake can be served in few different ways, see below for few suggestions:

• Turn it into layer cake - add a layer of passion fruit curd into the cake batter for even more exotic and tropical flavour! Transfer half of the cake batter into the baking tin, then add a layer of 3-4 tablespoons of passion fruit curd and spread it gently. Top with the remaining cake batter.
• Make mini-loaves - instead of using one large loaf tin, use two mini-loaf cake pans. Remember to reduce baking times.
• Top it up - add whipped cream or some buttercream instead of the drizzle. You can flavour the cream or the buttercream with some passion fruit juice. Or, just like in my Zesty Lemon Cake recipe, use the simple icing flavoured with citrus as a topping.
• Try it vegan - for a vegan passion fruit cake, check out this Easy Vegan Passionfruit Cake recipe from Rainbow Nourishments.

Equipment

• Handheld electric mixer or stand mixer fitted with paddle attachment.
• Loaf tin - This recipe was tested using 21.6 x 11.4 x 6.35 loaf tin, which is 1.2L capacity. You can use bigger loaf tin, but I wouldn't recommend going any smaller (unless baking 2 mini loaves in mini-loaf tins). You can also use square 20 x 20 cm baking tin, or 20 cm round baking tin instead.
• Baking parchment - Use baking paper for lining the tin with. Make sure there is plenty overhang, to prevent and spills and to help you remove the cake from the tin later.
• Sieve - Metal or plastic sieve.
• Skewer or cake tester.
• Pastry or silicone brush for brushing the syrup over the cake. This is optional, as you can also simply spoon out the fruit syrup onto the cake.

Storage

This passion fruit sponge cake will keep well at room temperature in the airtight container for up to 3 days.

You can also freeze any leftovers for up to a month. Wrap the cake into a double layer of clingfilm/ plastic wrap, and keep in the freezer. Thaw it in the fridge overnight.

If making ahead and freezing this cake, do not add the passion fruit drizzle or the sugared seeds to it. Simply freeze the cooled loaf, and only once it has been thawed, poke it with the skewer and drizzle with passion fruit juice. Otherwise the passion fruit juice will form ice crystals, and this can allow the freezer burn to set up.

FAQ's

Why is my cake flat?

This could be caused by few different factors. Your raising agent or flour was out of date, the cake batter has been overmixed or you used a significantly different size baking tin.

Why do you add soured cream into the cake batter?

Soured cream adds an extra moisture, without thinning the cake batter too much. It also creates creamier and richer texture of the cake. You could also use Greek yoghurt, buttermilk or coconut cream instead.

My cake turned soggy. Why is that?

You probably overmixed the cake batter, or you added the drizzle and the syrup into the cake that was still too warm. Remember to fold the batter gently, and stop mixing it as soon as you can no longer see any flour. And allow the cake to cool until barely warm, before adding the juice and the syrup drizzle to it.

Can I use different size of the baking tin?

Yes, you can. 1.2L loaf tin works best, but you can also use bigger loaf tin. Square or round baking tin (20cm) will also work, but baking times may need adjusting.

What does 'folding the batter' means?

Folding the batter involves a specific motion to ensure you don't deflate the batter. You gently mix the lighter ingredient into heavier cake batter, using a wooden spoon or a spatula. That means no stirring, beating or agitating the cake mixture. You simply start at the back of the mixing bowl, inserting the spoon or spatula vertically to cut through the both mixtures, across the bottom of the bowl and up the nearest side. The bowl should also be rotated slightly with each stroke.

Top tip

Sift the flour into the cake batter. Sifted flour is much lighter and easier to mix with other ingredients. It also eliminates any lumps or clumps.

Adding beaten eggs gradually, in small additions, prevents the cake batter from curdling.

If the cake starts to catch up the colour and browns up too quickly when baking, cover it with kitchen foil.

Poke the cake all over with cocktail stick or skewer. This way you will create little holes which will be filled with that delicious, sweet and tangy juice. This is what gives this cake it's incredible flavour.
