Lemon Cake Recipe

A deliciously tangy treat – this lemon cake recipe is so tasty and tart without being too sweet. The perfect pick me up on cold, grim days.

There is something about the bright, zesty aroma of a fresh lemon cake that can turn the gloomiest UK afternoon into a celebration. While I usually lean towards rich, chocolatey treats, sometimes your palate craves that sharp, citrusy “zing” that only real lemons can provide.

This isn’t just any lemon cake recipe. It’s a health-conscious, refined sugar-free, and incredibly moist loaf that rivals any high-street coffee shop version! By using wholemeal spelt flour and ground almonds, we’ve created a texture that is dense, satisfying, and naturally wholesome.

Loaf cakes are probably my favourite type of cake. They’re so dense, moist and satisfying. I’m not a big fan of cakes with cream or frosting, and loaf cakes don’t usually come with either. I feel the cake/frosting dilutes the flavour too much so you don’t actually get to appreciate the taste of the cake itself.

Why I think you’ll Love this healthier lemon cake recipe:

If you’re looking for a dessert that feels like an indulgence but is packed with better-for-you ingredients, this is it. Here is why this recipe has become a staple in my kitchen:

• Better-for-you ingredients: With less added sugar and I also subbed plain flour for wholemeal spelt and ground almonds. 

• Superior texture: The combination of spelt flour and ground almonds creates a “melt-in-your-mouth” crumb.

• Egg-free & dairy-free: Uses a simple flax egg for binding, making it 100% plant-based.

• One-bowl friendly: Minimal cleanup, maximum flavour.

The secret to a moist lemon cake: ingredient breakdown

The biggest challenge in vegan baking is achieving moisture without eggs. Here is how we do it:

The flour power: spelt & almonds – Most traditional recipes use all-purpose white flour. While delicious, it lacks fibre and nutrients. I use wholemeal spelt flour for a nutty undertone. However, the real secret is the ground almonds. Almonds contain natural fats that keep the loaf from drying out, even on day three.

The binder: milled flaxseed – A “flax egg” (milled flaxseed mixed with water) provides the structure. Flaxseeds are rich in Omega-3 fatty acids, adding a hidden nutritional boost to your cake.

The fat: coconut oil – Coconut oil provides a rich mouthfeel. If you prefer to avoid oil, you can substitute this with unsweetened applesauce or a thick vegan Greek-style yogurt, though the texture will be denser.

The star: fresh lemons – Never use bottled lemon juice! For the best taste, you need the zest of two lemons and the fresh juice of three. The zest contains the essential oils that provide that “bakery-style” fragrance.

Step-by-step guide: how to make the perfect lemon loaf

Step 1: prep the flax egg

Mix 2 tbsp of milled flaxseed with 5 tbsp of water. Set it aside for at least 10 minutes. It should turn into a thick, gelatinous consistency. This is what replaces the “lift” and “binding” of a chicken egg.

Step 2: mix your dry ingredients

In a large mixing bowl, whisk together your spelt flour, ground almonds, baking powder, baking soda, and a pinch of salt. Sifting the flour isn’t strictly necessary for this rustic loaf, but it does help create a lighter crumb.

Step 3: combine and fold

Pour in your wet ingredients: the maple syrup, melted coconut oil, and that punchy lemon juice. Finally, fold in your flax egg and lemon zest. Pro Tip: Do not over mix! Over mixing develops the gluten in the spelt flour, which can lead to a tough, rubbery loaf. Fold until just combined.

Step 4: the bake

Pour the batter into a lined 22×12 cm loaf tin. Bake at 180°C (160°C fan)/350°F for 45-50 minutes. You’ll know it’s ready when the top is golden brown and a skewer comes out clean.

Troubleshooting: 

Avoid sinking in the middle – This usually happens if the oven door is opened too early or if the leavening agents (baking powder/soda) are expired. Make sure your oven is fully preheated before the tin goes in!

Avoid a dry crumb – You might have measured the flour too heavily. Use a kitchen scale for the most accurate results. Also, ensure you aren’t over-baking; start checking the loaf at the 45-minute mark.

Avoid a dense cake – Spelt flour is heavier than white flour. If you want a fluffier, “cake-like” texture, you can use a 50/50 split of white plain flour and wholemeal spelt flour.

Customising your lemon cake recipe:

• Blueberry lemon loaf: Gently fold in 100g of fresh blueberries (tossed in a teaspoon of flour to prevent sinking) before baking.

• Poppy seed twist: Add 2 tablespoons of poppy seeds for a classic lemon poppy seed loaf.

• Herbal infusion: Add 1 tsp of finely chopped fresh thyme or rosemary for a sophisticated, savoury-sweet flavour profile.

Storage and freezing tips:

This loaf keeps beautifully. Store it in an air-tight container at room temperature for up to 4 days. Can you freeze this lemon cake? Yes! Slice the loaf first, place parchment paper between the slices, and freeze for up to 2 months. Toast a slice directly from the freezer for a quick breakfast treat.

What you need to make this lemon cake recipe:

• Spelt flour – I used wholemeal spelt flour as a healthier alternative to white flour.
• Ground almonds – this adds a lot of extra moistness. I used ground almonds, not almond flour. 
• Lemon juice – again adds a lot of moisture and natural lemon taste. 
• Lemon zest – to infuse the cake with extra citrus flavour and add lots of zing! 
• Milled flaxseed – this works as a binder. You can use whole eggs instead if you prefer. 
• Maple syrup – for much needed sweetness to counter the acidic and tart taste of the lemon.
• Coconut oil – this acts as another binder, but also adds more moisture, because no one likes a dry cake! 
• Optional drizzle – the loaf will still taste amazing without it, but the option is there in case you want extra sweetness. It also make the cake look so much prettier!
