Mediterranean Almond Orange Cake Flourless with Honey and Cardamom
Boil the orange first. This is the instruction that makes this recipe sound more unusual than it is, and it is also the instruction that makes this cake extraordinary. Two whole oranges, unpeeled, simmered in water for two hours until completely soft, then cooled, quartered, deseeded and blended skins and all into a thick, fragrant puree. The resulting puree goes into the cake batter in its entirety, contributing a depth of orange flavour, a slight bitterness from the pith and a moisture that keeps the almond flour cake tender for several days. This technique is ancient, used across Sephardic Jewish, Moroccan and Greek baking traditions, and it produces a cake that no amount of orange zest or extract can replicate.
Why this recipe works
The whole orange puree, including the pith, adds complexity that orange juice and zest alone cannot achieve. The pith contains compounds that are bitter when raw but transform during the two-hour boil into something mellow and fragrant that contributes to the finished cake's distinctive flavour. Almond flour provides the structure, richness and moisture retention that makes the cake feel almost fudgy in the best sense. Honey rather than refined sugar sweetens everything with a floral note that complements the orange. A small amount of cardamom, which is used alongside orange in many Mediterranean confectionery traditions, adds warmth and an aromatic quality.
Getting it right
Boil the oranges long enough. Two hours is the minimum. Under-boiled oranges retain bitterness in the pith that has not mellowed sufficiently and produces a cake with an unpleasant astringency. The orange is ready when a skewer goes through the whole fruit with no resistance.
Allow the orange puree to cool completely before adding it to the batter. Warm puree can begin to cook the eggs when they are mixed in together.
Common mistakes
Not removing the pips before blending produces a bitter, slightly fibrous puree. Quarter the boiled oranges and remove all visible seeds before processing.
Over-blending the batter with the orange puree incorporated can break down the almond flour particles and produce a denser, less airy cake. Mix until just combined.
Substitutions
Lemons can replace oranges for a sharper, more intensely citrus version. Clementines produce a sweeter, more delicate result. A tablespoon of rose water added to the batter alongside the cardamom gives the cake a distinctly Moroccan flavour profile.
Serving suggestion
Serve at room temperature, dusted with icing sugar and a scattering of toasted flaked almonds. A drizzle of honey over each slice adds gloss and sweetness. The cake keeps for four days in an airtight container and genuinely improves on the second and third day as the orange flavour develops.
Ingredients
- 2 medium navel oranges (whole, unwaxed, scrubbed well)
- 250 g fine almond flour (also called almond meal, not coarse ground)
- 2 tbsp ground flaxseed (adds fibre and binds lightly)
- 90 ml raw honey (or pure maple syrup for vegan version)
- 4 large eggs (at room temperature)
- 1.5 tsp baking powder (check it is gluten-free certified if needed)
- 1 tsp ground cardamom
- 0.5 tsp ground cinnamon
- 0.3 tsp fine sea salt
- 1 tsp pure vanilla extract
- 40 g flaked almonds (for topping, lightly toasted)
Instructions
- 1
Place the whole unpeeled oranges into a medium saucepan and cover completely with cold water. Bring to a boil over high heat, then reduce the heat to medium and simmer for 60 minutes, turning the oranges occasionally. They should feel very soft when pressed with a spoon.
Keep the oranges fully submerged by placing a small lid or heat-proof bowl on top to weigh them down during simmering.
- 2
Drain the oranges and allow them to cool until you can handle them comfortably, around 15 minutes. Cut each orange into quarters, remove any seeds, and transfer everything including the rind to a blender or food processor. Blend until completely smooth.
Do not discard any liquid that collects on the cutting board. It is flavourful and goes straight into the blender.
- 3
Preheat your oven to 170 degrees Celsius (150 degrees fan, 340 degrees Fahrenheit). Grease a 23cm (9-inch) round springform cake tin thoroughly and line the base with baking paper.
- 4
In a large mixing bowl, whisk the eggs and honey together for about 2 minutes until the mixture is slightly pale and well combined. Add the vanilla extract and whisk briefly to incorporate.
Room temperature eggs whisk more easily and blend more smoothly with the honey than cold eggs straight from the fridge.
- 5
Add the orange puree to the egg and honey mixture and stir until evenly combined. The batter will look quite loose at this stage, which is completely normal.
- 6
In a separate small bowl, stir together the almond flour, ground flaxseed, baking powder, cardamom, cinnamon and sea salt. Add this dry mixture to the wet ingredients and fold gently until no dry streaks remain. Avoid overmixing.
Folding rather than beating keeps the texture light and prevents the almond flour from becoming dense.
- 7
Pour the batter into the prepared tin and smooth the top with a spatula. Scatter the flaked almonds evenly over the surface, pressing them very gently so they sit just on the surface rather than sinking.
- 8
Bake in the preheated oven for 55 to 60 minutes. The cake is ready when the top is a deep golden brown and a skewer inserted into the centre comes out with just a few moist crumbs, not wet batter.
If the top starts to brown too quickly before the centre is set, lay a loose sheet of foil over the tin from around the 40-minute mark.
- 9
Remove the cake from the oven and allow it to cool in the tin for 20 minutes before releasing the springform and transferring to a wire rack. Allow to cool completely before slicing.
This cake slices most cleanly when fully cool. The texture also improves significantly after a few hours as the crumb settles.

Pro Tips
- ✓
Use unwaxed oranges wherever possible. If your oranges are waxed, scrub them thoroughly under warm water with a stiff brush before boiling.
- ✓
The orange puree can be made up to two days ahead and stored in the fridge, making this a very easy cake to prepare in stages.
- ✓
Allow the cake to cool completely before cutting. Cutting too early causes the crumb to tear and appear underbaked.
- ✓
Almond flour brands vary in texture. Finer, blanched almond flour gives a softer crumb than coarser almond meal, though both work in this recipe.
- ✓
A light drizzle of warm honey over the top just before serving adds a beautiful gloss and a touch of extra sweetness without refined sugar.
- ✓
For cleaner slices, use a sharp knife dipped briefly in hot water and wiped dry between each cut.
Frequently Asked Questions
Variations
- •
Lemon and Almond Version
Replace the two oranges with three unwaxed lemons, boiled in the same way. Reduce honey to 75ml as lemons are more tart. The result is sharper and more refreshing, with a beautiful pale crumb.
- •
Orange and Pistachio
Replace 60g of the almond flour with finely ground raw pistachios. This adds a gorgeous green fleck throughout the crumb and a more complex, earthy nuttiness that pairs beautifully with the orange and cardamom.
- •
Blood Orange Winter Cake
Use blood oranges instead of navel oranges when they are in season between December and March. They give the crumb a faint blush-pink tint and a slightly more berry-like citrus note that makes this cake feel extra special.
- •
Orange and Dark Chocolate
Fold 60g of finely chopped 85 percent dark chocolate into the batter just before pouring into the tin. The bittersweet chocolate marbles through the orange almond crumb and creates a richer, more dessert-forward cake with still-healthy credentials.
Substitutions
- •eggs → flax eggs (Use 4 flax eggs (4 tbsp ground flaxseed mixed with 12 tbsp water, rested 10 minutes) for a vegan version. The texture will be slightly denser and the cake may need an extra 5 minutes in the oven.)
- •raw honey → pure maple syrup (A direct 1:1 swap that keeps the cake refined sugar-free and makes it fully vegan. The flavour is slightly less floral but still delicious.)
- •ground cardamom → ground ginger (If you do not have cardamom, ground ginger provides a similar warmth and spice. Use the same quantity.)
- •navel oranges → clementines or mandarins (Use four clementines instead of two larger oranges. The simmering time reduces to around 40 minutes as they are smaller. The flavour is slightly sweeter and softer.)
- •fine almond flour → ground sunflower seeds (For a nut-free version, use the same weight of finely ground sunflower seeds. Note that the batter may turn slightly green due to a natural reaction between sunflower seeds and baking powder. This is harmless and the flavour is still good.)
🧊 Storage
Store the cooled cake in an airtight container at room temperature for up to 3 days, or refrigerate for up to 6 days. Because there is no dairy in the cake itself, it keeps very well. Bring refrigerated slices back to room temperature for 20 minutes before serving for the best texture. This cake also freezes well: wrap individual slices tightly in baking paper and then in foil, and freeze for up to 2 months. Thaw overnight in the fridge.
📅 Make Ahead
The boiled orange puree can be prepared up to 2 days in advance and kept covered in the refrigerator. The fully baked cake can also be made the day before serving, as the flavour and texture genuinely improve overnight. Simply store covered at room temperature and add the honey drizzle just before serving if using.
