What Makes Flourless Orange Pistachio & Almond Cake Special?

This cake is loved around the world for its unique qualities:

1. Naturally Gluten-Free

Instead of flour, the cake relies on finely ground almonds—a staple in Mediterranean desserts—to create structure and texture. This makes it ideal for those following a gluten-free lifestyle without compromising taste.

2. Whole-Orange Flavor

Unlike most citrus cakes, this recipe uses whole boiled oranges, including the peel. This method enhances the citrus aroma and gives the cake its deep, almost marmalade-like flavor.

3. Moist and Delightful Texture

The combination of eggs, almonds, and orange puree produces a soft, almost custard-like crumb that remains moist for several days.

4. Nutty & Aromatic Pistachio Crunch

Topping the cake with chopped pistachios elevates both flavor and presentation, adding a contrast of textures and a gorgeous, natural green color.

5. Minimal Ingredients, Maximum Flavor

You only need a few simple ingredients, many of which are pantry staples.

Ingredients You Will Need

As shown in the recipe card image, this cake requires only a handful of everyday items:

• 2 large oranges (preferably seedless)

• 6 large eggs

• 1 cup granulated sugar

• 2 ½ cups almond flour (or finely ground almonds)

• ½ cup chopped pistachios (plus extra for garnish)

• 1 teaspoon baking powder (optional but recommended)

• 1 teaspoon vanilla extract

• A pinch of salt

Step-By-Step: How to Make Flourless Orange Pistachio & Almond Cake

Follow these detailed steps to ensure your cake turns out perfectly moist and aromatic.

Step 1: Prepare the Oranges

Wash the oranges and place them in a pot of water. Boil for 60–90 minutes, or until the oranges are soft enough to pierce with a fork.
This removes bitterness from the peel and makes blending easier.

Once cooled, cut the oranges into quarters and remove any seeds. Blend the entire orange—peel and all—into a smooth puree.

Step 2: Prepare the Cake Batter

In a large bowl:

1. Whisk the eggs until frothy.

2. Add sugar and vanilla.

3. Stir in the orange puree.

4. Add almond flour, baking powder, and salt.

Mix until combined, but don’t over-mix; the batter should be thick and slightly textured.

Step 3: Fold in the Pistachios

Add chopped pistachios into the batter, reserving some for decoration.

Step 4: Bake the Cake

Pour the batter into a greased 9-inch springform pan lined with parchment paper.
Bake at 350°F (175°C) for 45–60 minutes, or until the top is golden and the center is fully set.

Step 5: Cool and Garnish

Allow the cake to cool completely before removing it from the pan.
Top with:

• A drizzle of orange glaze (optional)

• Fresh orange slices

• More chopped pistachios

Expert Tips for the Perfect Cake

• Boil oranges thoroughly — under-boiled oranges will make the cake bitter.

• Use almond flour for finer texture; ground almonds result in a rustic, coarser crumb.

• Let the cake rest overnight — the flavor intensifies beautifully.

• Store covered at room temperature for 2–3 days or refrigerate for up to a week.

• Serve warm with Greek yogurt, whipped cream, or vanilla gelato.

Serving Suggestions

To elevate presentation:

• Top with candied orange slices

• Dust with powdered sugar

• Garnish with crushed pistachios and orange zest

• Serve with a drizzle of honey or citrus syrup

Whether it’s for brunch, Eid, Easter, Christmas, or an everyday treat, this cake always impresses.

Frequently Asked Questions (FAQs)

1. Can I use lemons instead of oranges?

Yes! Lemon or a lemon-orange blend works well, though the cake will be tangier. Add extra sugar if desired.

2. Why did my cake turn out bitter?

Bitterness usually comes from under-boiled oranges. Make sure they are fully softened before blending.

3. Can I freeze this cake?

Absolutely. Wrap slices tightly and freeze for up to 3 months. Defrost at room temperature.

4. Is almond flour the same as almond meal?

Not exactly. Almond flour is finer, blanched, and gives a more tender texture. Almond meal is coarser and darker.

5. Can I reduce the sugar?

Yes—reduce to ¾ cup without affecting texture. You can also substitute coconut sugar.

6. Can I make this cake dairy-free?

It already is! No butter or milk is required.
