Ingredients You’ll Need

This recipe stands out because it relies on a handful of simple, wholesome ingredients, each playing a crucial role. From the fresh whole oranges bringing vibrant citrus flavor and moisture, to the almond meal which creates that signature dense, nutty crumb, every component is essential in crafting this cake’s magic.

2 medium oranges, fresh whole with rind on: Boiling the oranges softens the peel and intensifies the citrus flavor for an outstanding depth.
1 1/4 tsp baking powder: Adds just enough lift without compromising the dense texture we love.
6 large eggs, at room temperature: These provide structure and richness, making the cake lush but not heavy.
1 1/4 cups white sugar: Sweetness that balances the natural orange tartness beautifully.
2 3/4 cups almond meal / ground almonds: This flourless alternative lends moistness, nuttiness, and a tender crumb.

How to Make Whole Orange Cake – Flourless Recipe

Step 1: Prepare the Oranges

Start by thoroughly boiling your whole oranges right in their skins. Place them in a pot, cover with cold water, bring to a boil, and let simmer for 10 minutes. Drain and repeat this boiling process twice more. This step softens the peels, cutting their bitterness and making them melt into the cake. Once cooled, finely chop the softened oranges to prepare for blending.

Step 2: Blend and Mix the Batter

Preheat your oven to the right temperature while you blitz those boiled oranges in a food processor until smooth. Add the eggs, sugar, almond meal, and baking powder, then blend everything together until just combined. The batter will be thick and fragrant with fresh citrus notes, signaling you’re one step closer to an incredible cake.

Step 3: Bake to Perfection

Pour your batter into a prepared cake pan and bake in the oven for 60 minutes. The aroma that fills your kitchen is incredibly inviting—the oranges and almonds working their magic. Make sure to test the cake’s doneness with a toothpick; it should come out clean, showcasing that perfect balance of moist crumb with a slightly golden crust.

Step 4: Cool Fully Before Serving

This part is key! Allow the cake to cool completely in its pan. Cooling helps the flavors settle and the texture to firm up just right, making slicing easier and serving more elegant.

How to Serve Whole Orange Cake – Flourless Recipe

Garnishes

Keep it simple to let the star shine — a light dusting of powdered sugar or a few delicate almond flakes toasted till golden add just the right touch of sweetness and crunch. Fresh orange zest sprinkled on top can amplify the citrus aroma. If you want a bit of flair, a dollop of whipped cream or Greek yogurt pairs beautifully without overpowering the cake’s bright flavor.

Side Dishes

This cake pairs wonderfully with a warm cup of tea or fresh coffee, making it perfect for brunch or afternoon treats. For a more indulgent experience, serve alongside a scoop of vanilla ice cream or a drizzle of honey for subtle sweetness that complements the orange aroma.

Creative Ways to Present

For a stunning rustic presentation, serve wedges of the cake atop a wooden board garnished with edible flowers or fresh mint leaves. You can also slice it thin and layer with whipped mascarpone and fresh berries for a delightful twist as a light summer dessert. Offering it with citrus-infused cream cheese spread elevates the flavor profile impressively, making it a conversation starter at any gathering.

Make Ahead and Storage

Storing Leftovers

This Whole Orange Cake – Flourless Recipe keeps remarkably well when stored in an airtight container at room temperature for up to 3 days. The flavors will actually deepen overnight, so leftovers often taste even better the next day. Just keep it covered to maintain that lovely moist texture.

Freezing

If you want to save some for later, slice the cake before freezing for easy portioning. Wrap each piece tightly in plastic wrap and then place in a freezer-safe container or bag. It will keep well for up to 2 months. When you’re ready, thaw in the refrigerator overnight for the best texture.

Reheating

To revive a slice, warm it gently in a microwave for 20–30 seconds or pop it in the oven at a low temperature for a few minutes. This will soften the cake, restoring its fresh-baked feel, and bring out the lovely orange aromas once again.

FAQs

Can I use a different type of nut meal for this cake?

Yes! While almond meal is classic in this recipe for its flavor and moisture, you can try hazelnut or cashew meal. Just keep in mind the flavor will change slightly, but the texture should stay moist and dense.

Is this cake gluten-free?

Absolutely. This Whole Orange Cake – Flourless Recipe uses almond meal instead of flour, making it naturally gluten-free and perfect for anyone avoiding gluten.

Do I have to boil the oranges three times?

Boiling three times helps remove bitterness from the orange peel and softens it so it blends smoothly into the batter. It’s a small step with a big impact on flavor and texture, so I highly recommend it.

Can I use bottled orange juice instead of whole oranges?

Using whole oranges with peel is key here as the peel adds unique bitterness and oils that bottled juice just can’t replicate. This cake’s signature texture and flavor come from the whole fruit, so fresh oranges are essential.

What does this cake taste like?

Expect a wonderfully moist, dense cake with bright citrus notes and a subtle bittersweet edge from the orange peel. The almond meal adds a nutty richness that makes every bite deeply satisfying, refreshing, and comforting at the same time.
