Blueberries and custard, what a lovely match! There’s something about the combination of sweet, silklike vanilla custard and juicy sweet blueberries that is a winning concept if you ask me! Add these two ingredients to a cake batter and you have yourself a wonderful afternoon snack or dessert. With a soft, tender and juicy crumb, lovely swirls of vanilla custard, pieces of juicy blueberries and a hint of lemon this cake is sweet and delicious but still light, fresh and delicate at the same time. And it is everything you need when your sweet cravings kicks in. The cake is really easy and quick to make, using healthier and more nutritious ingredients than regular cakes. It is gluten, oil and sugar free and can easily be made dairy free as well. For the custard you can use homemade or storebought custard, that’s totally up to you. Eat this cake as an afternoon snack or serve it for dessert.

A few tips:

  • This version of the cake is made with yogurt custard. But I have made it with regular custard many times as well. You can choose to use any custard of your liking, homemade or storebought. 
  • I used fresh blueberries, but frozen ones work just as well.
  • If you want to make this cake dairy free you can easily replace the yogurt with a dairy free version. Just make sure the yogurt isn’t too thin.
  • I used a 16 cm spring form for my cake. You can make it in a larger spring form, but that will affect the baking time slightly and obviously the cake will become less tall.
  • Let the cake cool for 5-10 minutes, then run a sharp knife around the edges to loosen it. Then let it cool completely or at least for 20 minutes.
  • I prefer to let my cake cool completely before cutting into it. You can however cut it after 20 minutes, just make sure you cut it carefully while still warm.
  • This cake is good to store in the fridge for up to five days. Keep it in an airtight container so it doesn’t become dry.
