Lemon & Poppy Seed Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1½ cups (190g) all-purpose flour
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp fine salt
• ¾ cup (150g) granulated sugar
• 2 large eggs
• ½ cup (120g) full-fat Greek yogurt
• ⅓ cup (80ml) neutral oil
• Zest of 3 lemons
• 2 tbsp fresh lemon juice
• 2 tbsp poppy seeds
• 3 tbsp lemon juice + ¼ cup (50g) sugar (for the drizzle glaze)

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper, leaving overhang on the sides for easy removal.
2. Whisk the flour, baking powder, baking soda, salt, and poppy seeds together in a large bowl.
3. In a separate bowl, rub the lemon zest into the sugar until fragrant. Add the eggs, Greek yogurt, oil, sourdough discard, and lemon juice. Whisk until smooth.
4. Fold the wet ingredients into the dry until just combined — don’t overmix.
5. Pour into the prepared pan and bake for 50–55 minutes, until a toothpick inserted into the center comes out clean.
6. While still hot, poke holes across the top with a skewer. Stir the glaze ingredients together and pour slowly over the loaf. Let it soak in for 10 minutes before removing from the pan.
7. Cool on a wire rack, then slice and serve warm with lemon curd and clotted cream.

Chocolate Espresso Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1½ cups (190g) all-purpose flour
• ½ cup (50g) Dutch cocoa powder
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp fine salt
• 1 tsp espresso powder
• ¾ cup (150g) granulated sugar
• 2 large eggs
• ½ cup (120ml) buttermilk
• ⅓ cup (80ml) neutral oil
• 1 tsp vanilla extract
• ¾ cup (130g) dark chocolate chips, tossed in 1 tbsp flour
• ½ cup (120ml) heavy cream + 4oz (115g) dark chocolate (for ganache)

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. Whisk together the flour, Dutch cocoa, baking powder, baking soda, salt, and espresso powder in a large bowl.
3. In a separate bowl, whisk the sugar, eggs, buttermilk, oil, sourdough discard, and vanilla until fully combined.
4. Fold the wet ingredients into the dry until just combined. Gently fold in the flour-coated chocolate chips — the light flour coating keeps them suspended in the batter instead of sinking to the bottom.
5. Pour into the prepared pan and bake for 55–60 minutes for a fully set center, or pull it at 50 minutes if you prefer a fudgier middle. A toothpick should come out with a few moist crumbs.
6. Cool in the pan for 15 minutes, then transfer to a wire rack.
7. For the ganache, heat the heavy cream until just simmering, pour it over the chopped dark chocolate, and let it sit for 2 minutes before stirring it smooth. Pour over the cooled loaf and let it set before slicing.
8. Serve at room temperature alongside a scoop of vanilla ice cream.

Spiced Apple & Cinnamon Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1½ cups (190g) all-purpose flour
• 1½ tsp cinnamon
• ¼ tsp cardamom
• ⅛ tsp ground clove
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp fine salt
• ¾ cup (165g) light brown sugar
• 2 large eggs
• ½ cup (115g) brown butter, cooled
• ¼ cup (60g) sour cream
• 1 tsp vanilla extract
• 2 medium Bramley apples, peeled and diced small, tossed in 1 tbsp flour
• 2 tbsp demerara sugar (for topping)

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. To make brown butter, melt the butter in a light-colored saucepan over medium heat, swirling occasionally, until golden and nutty-smelling. Pour into a bowl and cool completely.
3. Whisk together the flour, cinnamon, cardamom, clove, baking powder, baking soda, and salt in a large bowl.
4. In a separate bowl, whisk the brown sugar, eggs, cooled brown butter, sour cream, sourdough discard, and vanilla until smooth.
5. Fold the wet ingredients into the dry until just combined. Gently fold in the flour-coated apple pieces — the flour coating prevents them from sinking as the loaf bakes.
6. Pour into the prepared pan, smooth the top, and scatter the demerara sugar evenly across the surface for a crackly cinnamon-sugar crust.
7. Bake for 55–60 minutes, until deep golden and a toothpick comes out clean.
8. Cool in the pan for 10 minutes, then transfer to a wire rack. Serve warm with custard or a spoonful of crème fraîche.

Banana, Date & Walnut Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1½ cups (190g) all-purpose flour
• 1 tsp baking powder
• ½ tsp baking soda
• ½ tsp cinnamon
• ¼ tsp fine salt
• ½ cup (110g) light brown sugar
• 3 tbsp maple syrup
• 3 very overripe bananas, mashed (about 1 cup)
• 2 large eggs
• ⅓ cup (80ml) neutral oil
• 1 tsp vanilla extract
• ¾ cup (130g) Medjool dates, pitted and roughly chopped
• ½ cup (55g) walnuts, toasted and roughly chopped

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. Toast the walnuts in a dry skillet over medium heat for 3–4 minutes, stirring frequently, until golden and fragrant. Set aside to cool.
3. Whisk together the flour, baking powder, baking soda, cinnamon, and salt in a large bowl.
4. In a separate bowl, mash the bananas thoroughly — the riper and darker the better, as fully overripe bananas have converted most of their starch to sugar, giving you natural sweetness and a moist, sticky crumb. Whisk in the brown sugar, maple syrup, eggs, oil, sourdough discard, and vanilla.
5. Fold the wet ingredients into the dry until just combined. Fold in the chopped dates and toasted walnuts.
6. Pour into the prepared pan and bake for 55–60 minutes, until a toothpick inserted into the center comes out clean and the top is deeply golden.
7. Cool in the pan for 10 minutes, then transfer to a wire rack.
8. Serve in thick slices with a generous spread of salted butter.

Blueberry & Vanilla Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1½ cups (190g) all-purpose flour, plus 1 tbsp for coating berries
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp fine salt
• ¾ cup (150g) granulated sugar
• 2 large eggs
• ½ cup (120g) full-fat Greek yogurt
• ⅓ cup (80ml) neutral oil
• 1 tsp vanilla extract (or seeds of ½ vanilla bean)
• Zest of 1 lemon
• 1½ cups (210g) fresh blueberries, tossed in 1 tbsp flour
• ¾ cup (90g) powdered sugar + 2 tbsp lemon juice (for glaze)

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. Whisk together the flour, baking powder, baking soda, and salt in a large bowl.
3. In a separate bowl, rub the lemon zest into the sugar until fragrant. Add the eggs, Greek yogurt, oil, sourdough discard, and vanilla. Whisk until smooth.
4. Fold the wet ingredients into the dry until just combined. Toss the blueberries in 1 tablespoon of flour before folding in — this prevents them from bleeding into the batter and sinking. If using frozen berries, fold them in straight from the freezer without thawing to minimize color bleed.
5. Pour into the prepared pan and bake for 55–60 minutes, until a toothpick comes out clean and the top is golden.
6. Cool completely on a wire rack before glazing.
7. Stir the powdered sugar and lemon juice together until smooth, then drizzle over the cooled loaf.
8. Serve chilled with softly whipped cream on a warm afternoon.

Orange & Cardamom Sourdough Loaf Cake

Ingredients

• 1 cup (200g) sourdough discard, room temperature
• 1¼ cups (160g) all-purpose flour
• ¼ cup (45g) fine semolina
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp fine salt
• 1 tsp ground cardamom
• ¾ cup (150g) granulated sugar

• ½ cup (120ml) orange juice + 3 tbsp sugar (for syrup soak)

Method

1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. Whisk together the flour, semolina, baking powder, baking soda, salt, and cardamom. The semolina adds a subtle crunch and a beautiful golden color to the crumb.
3. In a separate bowl, rub the orange zest into the sugar until fragrant and slightly damp. Whisk in the eggs, Greek yogurt, oil, sourdough discard, and orange juice until smooth.
4. Fold the wet ingredients into the dry until just combined — don’t overwork it.
5. Pour into the prepared pan and bake for 50–55 minutes, until golden and a toothpick inserted into the center comes out clean.
6. While the loaf bakes, make the orange syrup: simmer the orange juice and sugar in a small saucepan for 3–4 minutes until slightly reduced. Stir in the rose water if using.
7. As soon as the loaf comes out of the oven, poke holes across the surface with a skewer and slowly pour the warm syrup over the top. Let it soak in fully before removing from the pan.
8. Serve with mint tea or Turkish coffee for a fragrant, unhurried moment.
