WHAT YOU’LL NEED (INGREDIENTS)

The ingredient list is beautifully short, highlighting the orange. Quality matters here.

For the Cake:

• 1 large organic navel or Valencia orange (about 10 oz/280g): Must be organic since you’ll eat the peel. Scrub it well.
• 3 large eggs, at room temperature: Essential for proper emulsification.
• 1 ¼ cups (250g) granulated sugar: Sweetens and structures the cake.
• 2 ½ cups (250g) finely ground almond flour (almond meal): This is our “flour.” Ensure it’s fresh and finely ground.
• 1 teaspoon baking powder: For a gentle lift.

For the Optional Orange Glaze:

• 1 cup (120g) powdered sugar, sifted
• 2-3 tablespoons fresh orange juice
• Optional garnish: A sprinkle of slivered almonds or a twist of orange zest.

TOOLS YOU’LL WANT

You’ll need a small saucepan, a high-speed blender or food processor, a stand mixer or electric hand mixer, a 9-inch springform pan (ideal), parchment paper, and a fine mesh sieve for the glaze.

STEP-BY-STEP: HOW TO MAKE SICILIAN WHOLE ORANGE CAKE

Follow these Sicilian Whole Orange Cake steps for a perfectly moist, fragrant cake. The process is as unique as the result.

PREPARE THE WHOLE ORANGE

This is the signature step. Place the whole, scrubbed orange in a saucepan and cover it completely with water. Bring to a boil, then reduce the heat, cover, and simmer for 45 minutes to 1 hour until the orange is very soft and pierces easily with a knife. This process removes bitterness and softens every part of the fruit.

Drain the orange, let it cool until manageable, then cut it into quarters, removing any hard seeds. Place all the orange quarters (skin, pith, and flesh) into your blender or food processor and blend into a smooth, thick puree. Let it cool to room temperature.

MAKE THE CAKE BATTER

Preheat your oven to 350°F (180°C). Grease a 9-inch springform pan and line the bottom with parchment paper. In the bowl of a stand mixer fitted with the paddle attachment (or with a hand mixer), beat the eggs and sugar on medium-high speed for a full 5-7 minutes. The mixture should become very pale, thick, and ribbon-like.

This incorporates air and is key to the cake’s texture. Gently fold in the cooled orange puree until just combined. In a separate bowl, whisk together the almond flour and baking powder. Gradually fold the dry ingredients into the wet ingredients, using a gentle hand to maintain the batter’s airiness.

BAKE TO PERFECTION

Pour the batter into your prepared pan, smoothing the top. Bake for 45-55 minutes, or until the top is deep golden brown, the edges pull away from the pan, and a skewer inserted into the center comes out clean. Due to the moisture from the orange, this cake may take longer to bake than you expect don’t under-bake it.

COOL AND GLAZE

Let the cake cool in its pan on a wire rack for at least 30 minutes before carefully releasing the springform sides. Let it cool completely. For the glaze, whisk the sifted powdered sugar and orange juice until smooth. It should be thick but pourable. Drizzle artfully over the completely cooled Sicilian Whole Orange Cake. Garnish if desired.

TIPS AND TRICKS FOR PERFECT CAKE

Master your Sicilian Whole Orange Cake with these secrets. First, be patient boiling the orange; it’s the foundation of flavor. Second, whip the eggs and sugar thoroughly; this provides the cake’s primary lift. Third, use a light hand when folding in the almond flour to keep the batter airy. Finally, let it cool completely before glazing or serving; the flavor and texture set perfectly as it cools.

VARIATIONS YOU’LL ACTUALLY TRY

Once you master the classic, experiment. For a chocolate-orange twist, fold ½ cup of dark chocolate chips into the batter. For a citrus blend, use one small orange and one small lemon. For an herbal note, add 1 tablespoon of finely chopped fresh rosemary to the batter. For a dairy-rich version, serve slices with a dollop of sweetened mascarpone or whipped cream.

MAKE-AHEAD, STORAGE & FREEZING

This Sicilian Whole Orange Cake is even better on day two! Store it covered at room temperature for up to 3 days, or in the refrigerator for up to 5 days. It can be frozen (unglazed) for up to 3 months. Wrap it tightly in plastic wrap and then foil. Thaw overnight in the fridge.

TROUBLESHOOTING COMMON QUESTIONS

Let’s solve any baking puzzles. If your cake is too wet/dense in the center: It was under-baked. Bake until the skewer is truly clean. The orange adds a lot of moisture. If it sinks in the middle: The eggs and sugar may not have been whipped enough, or the oven was opened too early. If the top browns too quickly: Tent it loosely with foil for the last 15-20 minutes of baking. If it’s bitter: The orange may not have been boiled long enough, or it wasn’t organic.

SERVING SUGGESTIONS SICILIAN WHOLE ORANGE CAKE

SICILIAN WHOLE ORANGE CAKE FAQS

Can I use a regular orange if it’s not organic?
It is not recommended. Non-organic citrus skin can contain pesticides and waxes you don’t want to eat. If you must, scrub the orange intensely with a vinegar solution and a brush.

What can I use instead of almond flour?
Almond flour is essential for texture and structure. A gluten-free all-purpose blend will not yield the same result. For a nut-free version, sunflower seed flour can work, but it may impart a green tint over time.

My puree seems watery. Is that okay?
Yes, that’s normal. Just ensure you’ve blended it until as smooth as possible. The natural moisture is part of the recipe’s magic.
