I’m not messing around when I say this blueberry lemon yoghurt cake is absolutely bursting with lemon flavour and plump blueberries. It’s tangy, moist, soft and has a simple lemon glaze that makes it the perfect sweet tea-time treat.

If you like this, you’ll love my lemon ricotta cake or this lime and coconut cake.

Why you’ll love it

Say hello to your new favourite loaf cake. This lemon yogurt loaf cake is moist and tangy from lemon and yoghurt and filled with fresh, juicy blueberries.

The texture is lusciously soft and moist – no dry cakes around here please and it’s the yoghurt that helps with that.

And when it comes to taste, this lemon loaf is the real deal! It has a big hit of lemon flavour – not just a background hint but a bold, unmistakable lemon tang that comes from both loads of juice and zest in the cake batter itself. Top it off with a simple 2 ingredient lemon icing, and you know the lemon lovers in your life will be very happy, indeed

Ingredients you’ll need

A simple cake batter with loads of lemon and blueberries, there’s nothing out of the ordinary here.

Detailed quantities and instructions in the recipe card below.

  • Blueberries: Fresh blueberries are best but frozen will work. If using fresh, wash and dry them well. If using frozen, make sure to keep them frozen right up until you add them to the batter.  
  • Flour: You’ll just need plain flour / all purpose flour. Make sure to measure it correctly. Too much flour will give you a dry cake.
  • Baking powder: Baking powder gives this cake it’s lift.
  • Salt: Just a touch of salt to intensify flavours.
  • Butter: Use unsalted butter here, softened to around room temperature so it beats up easily.
  • Sugar: Just white granulated sugar or caster sugar (superfine sugar) is all you need) for the batter.
  • Lemon: Roughly 2 medium lemons will get you the right amount of zest and juice.
  • Eggs: Use large eggs, free-range if you have the means.
  • Greek yoghurt: Full fat Greek yogurt is best here. It keeps the cake moist.
  • Vanilla: Use pure vanilla extract. Essence is a synthetic flavouring and just not as good as the real thing.
  • Icing sugar: Icing sugar (not pictured), also known as powdered sugar or confectioners’ sugar, is one part of the two ingredient icing.

You could also try any other citrus in place of the lemon here. Limes, grapefruit and oranges would all be wonderful.

How to make blueberry lemon yoghurt cake

Detailed quantities and instructions in the recipe card below.

  1. The dry ingredients: Whisk together the flour, baking powder and salt in a mixing bowl until dispersed. Set aside.
  2. The wet ingredients: In a small jug, combine the yoghurt, lemon juice and vanilla. Set aside.
  3. The lemon sugar: Blend the lemon zest and sugar together with your fingertips. This releases the oil in the zest and intensifies the lemon flavour.
  4. Make the batter: Just like a basic cake batter, beat together the sugar and butter until lightened and creamy. Add the eggs 1 at a time, beating between each until smooth and combined. Now alternate adding the flour mixture and the yoghurt mixture, stirring each time until it’s just combined – don’t overmix.
  5. Add the blueberries: Now add in those blueberries and gently fold them into the batter, being careful so you don’t break them.
  6. Bake: Tip the batter into your prepared pan and bake the cake in the middle of a preheated oven for nearly an hour or until a toothpick comes out with just a crumb or two attached.
  7. The lemon icing: All your lemon yogurt cake needs now is a glaze. Once the cake has cooled, combine the icing sugar and a little lemon juice and mix well. Drizzle the icing all over the top of the cake. 

That last bit is if you can even wait for it to cool. Last time I made this cake, I literally ate nearly a full slice, uniced while still warm without even realising it.

Tips and tricks

  • Room temp ingredients: Make sure to bring your cold ingredients up to or close to room temperature. The butter should be softened, the yoghurt not too cold, the eggs and lemons room temperature.
  • Measure the flour correctly: Too much flour will make your cake dry and dense so use a kitchen scale for the best results. If you don’t have them (order one and while you wait…) fluff up the flour in the container a little, spoon it into your cup measure, then use the back of a knife to level off the top.
  • Frozen blueberries: If using frozen berries, keep them frozen right up until you add them to the batter, don’t thaw them first.
  • Flouring the blueberries stops the them from all sinking to the bottom of the cake.
  • Don’t overmix: Overmixing cake batter can lead to a dense cake so just lightly mix it together until just combined.
  • Grease and line your pan: This will make it so much easier to remove the cake from the pan later.

Storage

Store this blueberry lemon yoghurt cake in an airtight container at room temperature for 1 day. After that it will need to be refrigerated for 2-3 days. Bring it to room temperature before serving.

FAQ’s

Can I make this in a bundt tin?

Yes, you can turn this cake into a bundt cake. You’ll need to double the batter but may not use it all depending on the size of your bundt tin. Just fill to about ⅔ to ¾ full.

Can I use sour cream?

If you don’t have or can’t get any Greek yoghurt, a great substitute is sour cream.

Notes

  1. I use a standard Australian 20ml tablespoon (= 4 teaspoons worldwide)
  2. For best results you should always weigh ingredients like flour and sugar. Kitchen scales are relatively cheap but if you can’t weigh the ingredients, use the spoon and level method (don’t scoop).
  3. Baking time: The baking time will depend on your oven and the exact loaf tin size you’re using and your oven. Check for doneness 5-10 minutes before the recipe suggests.
  4. Store this blueberry lemon yoghurt cake in an airtight container at room temperature for 1 day. After that it will need to be refrigerated for 2-3 days. Bring it to room temperature before serving.
