All About This Vegan Gluten-free Lemon Poppy Seed Cake with Thyme
Poppy seeds and lemon are a classic flavour combination, sure to please most cake eaters. I added fresh thyme from my greenhouse, to highlight the lemon notes. Thyme presents earthy, minty and slightly lemony characteristics so it’s a great addition to this cake. The cake crumb is surprisingly soft with a crumbly, moist sponge like texture. The gluten-free flour blend creates a flawless crumb that’s impossible to tell it’s vegan or gluten-free. It’s a 1-bowl (and a jug) cake that’s vegan, gluten-free, and it’s absolutely delightful. It’s a fantastic choice for an easy afternoon tea cake as it’s a single layer 8 inch round cake that measures around 1.5 inches in height. This recipe will become a staple in your household, especially if you have fussy gluten-free eaters.

This cake uses a combination of white rice flour, almond flour, and potato starch as it’s gluten-free flour blend. Our egg replacer is xanthan gum which is a great egg replacer for gluten-free baking. It works as a binding agent and also helps create a spongy cake texture, which is hard in gluten-free vegan baking. A combination of coconut yoghurt, vegetable oil, and soy milk add the perfect amount of moisture to this cake, making one that will easily keep for 3 days without drying out.
This is only a single layered 8 inch cake. I use a standard 8 inch cake tin for this recipe. The brand I alway buy (and cherish) is USA Bakeware. I LOVE their cake tins. They are high quality, light coloured and last forever. This cake will present a slightly domed top and is very easy to decorate. I use a simple glaze recipe that is flavoured with vanilla, lemon essence, lemon rind and Thyme.

- 3 tablespoons poppy seeds
- 1 teaspoon baking powder

- 170 g (2/3 cup) caster sugar
- 125 ml (1/2 cup) plain vegan coconut yogurt
- 90 ml (1/3 cup + 2 teaspoons) vegetable oil
- 330 ml (1 1/3 cups) plant milk

- 1/2 teaspoon vanilla bean paste
- 1/2 teaspoon lemon extract
- Zest from one unwaxed lemon

Instructions
Cake
- Preheat your convection oven to 170°C (340°F). Lightly grease and line one 8 inch round cake cake tin with baking paper and grease again.
- In a large mixing bowl, sift the rice flour, almond flour, potato starch, poppy seeds, baking powder, baking soda, salt, and xanthan gum. Whisk to combine. Add sugar and stir through. Make a well in the middle of your dry ingredients.
- Place the coconut yoghurt, oil, plant milk, vanilla, lemon extract and zest in a large jug and stir until completely smooth.
- Slowly pour the wet ingredients into the bowl of dry and gently whisk to combine.
- Pour the batter into your cake tin and tap on your bench with force to release any large air bubbles.
- Bake on the middle rack of your oven for 45 – 48 minutes (BUT check your cake’s progress at the 40 minute mark), until a skewer inserted into the center comes out almost clean of cake batter and the top bounces back when gently pressed.
- Let cool in the tin for 10 minutes before flipping onto a cake rack to allow your cake to completely cool. Once your cake has cooled, move onto making the glaze.
Glaze
- Mix the icing sugar, soy milk, vanilla, lemon extract, lemon rind together in a small bowl until it becomes a smooth, thick icing. Pour evenly over the top of your cooled cake. Sprinkle thyme leaves over the top and some small lemon wedges. Serve.
