Substitutions you can make

  • You can use any type of oil: coconut oil, vegetable oil, olive oil etc.
  • You can use any type of liquid sweetener: maple syrup, agave syrup, brown rice syrup etc.
  • You can use any type of plant-based milk: almond milk, oat milk, soy milk, cashew milk, rice milk etc.
  • If you don't need the cake to be gluten-free,you can replace the gluten-free flour with plain flour.
  • The ground almonds can be replaced with ground walnuts.
  • For a nut-free version, use ground sunflower seeds instead of ground almonds, use a nut-free plant-based milk and omit the frosting or make a different frosting.

Tips for baking with lemons

  • For optimum lemon flavour, I would recommend using fresh lemons (not ones that you've had sitting in your fruit bowl for weeks!) and organic ones if possible.
  • You have to be careful when baking with lemon juice as the acidity and lemon flavour can really vary depending on the lemons you use.
  • I would recommend tasting the lemon juice you're using and adjusting the amount of lemon juice you use accordingly.
  • For the lemon zest, make sure you use unwaxed lemons.

How long does this Lemon Poppy Seed Cake keep for?

This Lemon Poppy Seed Cake tasted best eaten on the day it was made, but keeps covered in the fridge for up to a few days.

Ingredients

For the cake:

  • 180 ml (¾ cup) unsweetened almond milk (or any other plant-based milk)
  • 8 tablespoons lemon juice
  • 2 tablespoons lemon zest (use unwaxed lemons)
  • 12 tablespoons maple syrup (or sub any other sweetener)
  • 1 teaspoon vanilla extract
  • Pinch salt
  • 3 tablespoons poppy seeds
  • 150 g (1 ¼ cup) ground almonds (almond meal) *
  • 150 g (1 ¼ cup) gluten-free flour blend (or sub plain flour if not gluten-free)
  • 2 heaped teaspoons baking powder (ensure gluten-free if necessary)
  • ¼ teaspoon bicarbonate of soda (baking soda)

For the frosting:

  • 100 g ( cup) raw cashew nuts soaked in cold water overnight or in hot water for 15 minutes
  • 6 tablespoons maple syrup (or sub any other sweetener)
  • 4 tablespoons lemon juice

To decorate (optional):

  • Lemon zest
  • Poppy seeds

Instructions

For the cake:

  • Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit).

  • Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave (skip this step if using any other oil).

  • Once melted, add the milk to the same bowl along with the lemon juice, lemon zest, maple syrup, vanilla, salt, poppy seeds and ground almonds.

  • Sift in the flour, baking powder and bicarbonate of soda.

  • Mix well, adding a tiny splash more milk if it’s looking too dry.

  • Transfer mixture into a loaf tin lined with greased baking paper (I used a one-pound loaf tin).

  • Bake in oven for 45 minutes until risen and golden brown and an inserted skewer comes out clean.

  • Once out the oven, transfer the cake from the baking tin onto a wired rack to leave it to cool completely before applying the frosting.

For the frosting:

  • Drain the soaked cashews and add to a food processor or blender with the maple syrup and lemon juice.

  • Whizz until completely smooth, adding some plant-based milk or water to thin out if necessary.

To frost and decorate the cake:

  • Use a knife (or palette knife) to spread frosting over the top of the loaf.

  • Decorate with lemon zest and poppy seeds, if desired.

  • This cake tasted best eaten on the day it was made, but keeps covered in the fridge for up to a few days.

    I had a craving for cake and this was the recipe I tried. I'm so glad I did!! It was delicious - the tang of lemon and the quiet sweetness of maple syrup made it so satisfying. Knowing that the ingredients are healthy options, just made it even more tasty! I used almond meal that was left from making almond milk.

      Thank you so much, so happy to hear that!

    You mentioned "Sift in the flour" in step 4. Should the flour be measured by sifting or just scooping it out into a measuring cup then sifted in to the mixture? Measuring the flour by just spooning it in or pouring it in the measuring cup is more "packed" and will measure differently than sifting, is why I ask. Thanks! 🙂

      Hi, you can measure the flour before sifting! I hope that helps!
