How to make this Gluten-Free Vegan Lemon Poppy Seed Cake
Scroll to the bottom of the post for the full recipe.
- Mix together the ingredients for the cake in a glass mixing bowl.
Tip: Use a measuring jug to measure out the plant-based milk.
- Transfer the cake batter into a one-pound loaf tin.
Tip: Make sure to line the loaf tin with greased baking paper – this will make removing the cake from the tin so much easier!
- Bake in the oven for 45 minutes.
- Transfer to a cooling rack to cool down before applying the frosting.
How to make the frosting
- Place the ingredients for the frosting in a food processor or blender.
- Whizz until completely smooth, adding some plant-based milk or water to thin out if necessary.
- Use a knife (or palette knife for frosting) to spread the frosting over the top of the loaf.
How to decorate this cake
I decided to decorate this cake with lemon zest and poppy seeds, but you can use whatever you like!
Substitutions you can make to this recipe:
- 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 Gluten-Free Vegan 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.

Hello Rhian! Looking to try this wonderful recipe, but my question is : if I use almond flour, do I use the same amount as your recipe calls for? (I’ve had horrible luck baking with almond and coconut flour, now I’ve got the fear of ruining my cake!)
Rhian Williams
Yes you can use the same amount of almond flour! If you’ve had bad experiences with it in the past in a similar recipe then you can stick to ground almonds/almond meal to be on the safe side, but I think it should be ok!
Susana Santaigo
Can you substitute Gluten free flour for any other flour? I can’t have any GUMS.
Rhian Williams
I use a gluten-free flour that doesn’t contain any gums (Dove’s Farm gluten-free flour), but you can replace it with rice flour and add a couple of tablespoons of tapioca flour!

Hey there! Adding cold almond milk/other cold ingredients to melted coconut milk might result in clumps, so I typically let it cool a bit or “cream” it with any sugar used in the recipe first. Just thinking of mistakes I’ve made before 🙂 so excited to try this out!
