Another delicious recipe by Aran Goyoaga that was shared in her newsletter. I adapted it slightly by making it vegan, replacing the three eggs with ground flaxseed, adding baking powder, using maple syrup instead of honey and reducing the glaze by half.
I have recently entered the world of sourdough bread, and every Monday, I make a loaf of sourdough to bake the following day, so this recipe was perfect for using any leftover starter and using up the lemons that are hanging heavy from the trees in the garden.
The sourdough starter does add more complexity to the crumb. I use a 1:1 ratio, meaning equal amounts of flour and water.
If you don’t have a sourdough starter to discard, replace it with ½ cup/70g rice flour and ⅓ cup/80g of water/buttermilk, and increase the baking powder to 1 ½ teaspoon.

tip
- Save time; soak the flaxseed first, grate the zest and prepare the other ingredients, giving the flax the time it needs to thicken.
lemon-pound sourdough cake
Preparation 15 minutes
Baking 45 – 55 minutes
Makes one pound cake (11 x 25cm loaf pan) or 14 cupcakes (baked for 25 minutes, using these cake liners)
*I take my starter (sourdough leaven) from the fridge in the evening, just before bed, measure out 40g, and then feed it – 100g flour + 100g water. Allow it to sit overnight; by the morning, it may be fully active, or even if it has deflated already or hasn’t quite reached its full potential, no matter. With this starter, I make this lemon-pound sourdough cake.
ingredients
3 Tbsp/22g ground flaxseed + ½ cup/100g hot water (allow to sit for 10 mins as below)
¾ cup/150g light brown sugar
2 Tbsp finely grated lemon zest (zest from 3 lemons), plus more for garnishing
2 Tbsp/50g maple syrup (this gives a crisp caramelized exterior)
*½ cup + 2 Tbsp/200g sourdough starter
½ cup/110g extra virgin olive oil or neutral-tasting oil
¼ cup/55g lemon juice (1 very juicy lemon)
1 cup/140g brown rice flour
1 cup/100g almond flour
¼ cup/30g tapioca starch (or arrowroot powder)
¾ tsp fine rock salt
¾ tsp baking soda
1 tsp baking powder
glaze
2 Tbsp/25g light brown sugar
2 Tbsp/27g lemon juice (½ of a very juicy lemon)
preparation
1. Preheat your oven to 180C/350F. Generously grease your loaf pan.
2. Into a large bowl, add the flax with water and allow to sit for 10 minutes, then add sugar, zest, maple syrup, sourdough starter, oil and lemon juice – whisk until smooth.
3. In a small bowl, measure the brown rice flour, almond flour, tapioca starch, salt, baking soda and powder.
4. Add the dry ingredients to the wet and whisk until smooth. Pour into the prepared pan and bake for 45 – 55 minutes (my oven took 55 minutes.) Bake until a toothpick inserted in the middle of the cake comes out clean. Let the cake cool completely in the pan, then invert it onto a platter.
5. Meanwhile, make the glaze by gently heating the sugar and lemon juice in a small pan until the sugar dissolves – don’t heat for too long. Immediately brush the top of the cake, allowing it to drip over the sides. Generously garnish the top with lemon zest (I like combining lime, lemon and orange.)
note
- Use a metal pan, as suggested and grease it well. Alternately, you can line it with baking paper, making it easier to lift out of the pan, but note that the exterior won’t caramelize, as it won’t be in direct contact with the metal.
- Important! Let the cake cool completely. This will allow the crumb to set nicely and not fall apart.
variation with blueberries/blackberries
- Fold in 1 cup/125g of blueberries into the batter.
(Always toss the blueberries in cornstarch or tapioca flour before adding them to your batter. This will stop them from sinking to the bottom.)
