Zesty Mediterranean Sugar-Free Lemon Loaf
Sunday mornings in my Barcelona kitchen demand this cake. Not request — demand. It fills the whole flat with citrus before the coffee is even made, which I consider a public service.
It is moist, properly zesty, and pairs extraordinarily well with a small dollop of Greek yogurt — because even my cake needs a sidekick. The olive oil keeps everything tender in a way butter alone never quite manages, which is a very Mediterranean discovery I am now evangelical about.
The monk fruit here is important. It has a clean sweetness that lets the lemon be the main character rather than competing with it. Other sweeteners can overwhelm the citrus, and this cake is entirely about the citrus.

Ingredients
Serves 10 slices · Scale as needed
- 250g (2½ cups) ⇄ almond flour — the flour swap ⇄ the swap
- 100g (½ cup) ⇄ monk fruit sweetener — the sweetener swap ⇄ the swap
- 1 tsp baking powder
- 3 large eggs
- 60ml (¼ cup) extra virgin olive oil
- 60ml (¼ cup) fresh lemon juice (about 2 lemons)
- 2 tbsp lemon zest
- 1 tsp vanilla extract
Instructions
- 1
Preheat oven to 170°C (340°F) and grease a standard loaf pan, then line with parchment paper.
- 2
In a large bowl, whisk the almond flour, monk fruit, and baking powder until combined.
- 3
In another bowl, beat the eggs with olive oil, lemon juice, lemon zest, and vanilla.
⇄ Swap NoteMonk fruit provides a clean sweetness that lets the fresh lemon be the star without any bitter aftertaste.
- 4
Pour the wet ingredients into the dry and stir until just combined — don't overmix.
- 5
Transfer the batter to the prepared loaf pan and smooth the top with a spatula.
- 6
Bake for 40–45 minutes until golden on top and a toothpick inserted into the centre comes out clean.
- 7
Let the cake cool in the pan for 10 minutes before transferring to a wire rack.
- 8
Slice only once completely cool — the almond flour structure needs time to set.
Why I Made This Swap
A standard lemon loaf slice contains around 30g of sugar — mostly from refined sugar, with a sugary glaze on top adding even more. Almond flour provides protein and healthy fats that make each slice genuinely satisfying, while monk fruit gives clean sweetness without the bitter aftertaste that plagues many sugar-free baked goods. Olive oil keeps the crumb moist for days.
Common Mistakes
- Opening the oven too early. Almond flour cakes are more delicate than wheat flour ones. Don't open the oven door before 35 minutes.
- Cutting while warm. This cake slices cleanly only when completely cool. Warm, it will crumble. Worth the wait.
- Using bottled lemon juice. Fresh only. The difference is enormous and this cake deserves it.
Storage
Store in an airtight container at room temperature for 2 days or in the fridge for up to 5. It also freezes beautifully — slice first, wrap individually, freeze for up to 1 month.

Frequently Asked Questions
Can I make this into muffins?
Yes — divide into a 12-cup muffin tin and reduce the baking time to about 20–22 minutes.
Can I add a glaze?
A simple drizzle of powdered monk fruit mixed with a little lemon juice works perfectly and adds very little sugar.
My cake is very brown on top but not cooked through — what happened?
Cover loosely with foil after 30 minutes and continue baking. Almond flour browns faster than wheat flour.
