Flourless Orange Pistachio and Almond Cake – A Citrus Symphony of Comfort
There’s a certain kind of magic that happens when you combine citrus and nuts — especially in this Flourless Orange Pistachio and Almond Cake, a dessert that’s equal parts rustic and elegant. The fragrance alone — that dreamy mix of fresh oranges, toasted nuts, and vanilla — can make your kitchen feel like a Mediterranean haven.
This cake has roots that stretch back to the sun-drenched coasts of Spain and Italy, where flourless nut cakes are a beloved tradition. The texture is dense yet tender, the crumb perfectly moist, and each bite sings with the flavor of real oranges and warm nuttiness. It’s the kind of dessert that doesn’t shout for attention but quietly wins over everyone who takes a forkful.
I first tasted this cake at a small family gathering one winter afternoon. My aunt, who adores citrus desserts, baked it using the simplest ingredients — just ground nuts, sugar, eggs, and whole oranges boiled until soft. When she sliced it, the aroma was heavenly. We all sat around the table, savoring the cake with cups of strong coffee, marveling that something without flour could taste so rich and complete.
This is that kind of cake — the kind that turns a quiet afternoon into a memory.
Ingredients:
- 2 medium oranges (seedless, washed)
- 1 cup unsalted shelled pistachios
- 1 cup almond flour (or finely ground almonds)
- 1 cup granulated sugar
- 5 large eggs
- 1 teaspoon baking powder
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- Powdered sugar and extra crushed pistachios, for garnish
Instructions:
- Boil the Oranges: Place whole unpeeled oranges in a saucepan, cover with water, and simmer for about 60 minutes until very soft. Drain and let cool. Cut open to remove any seeds, then blend the oranges (peel and all) into a smooth purée.
- Preheat the Oven: Set the oven to 350°F (175°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
- Grind the Pistachios: Pulse pistachios in a food processor until finely ground (but not a paste).
- Mix the Dry Ingredients: In a bowl, combine ground pistachios, almond flour, baking powder, and salt.
- Beat the Eggs and Sugar: In a large mixing bowl, beat the eggs and sugar together until thick, pale, and slightly frothy — about 3–4 minutes.
- Combine: Fold in the orange purée, vanilla, and nut mixture until fully blended.
- Pour and Bake: Pour the batter into the prepared pan and bake for 45–55 minutes, or until a skewer inserted into the center comes out clean.
- Cool and Decorate: Let the cake cool completely before removing from the pan. Dust with powdered sugar and sprinkle with crushed pistachios.

- For extra aroma, add a touch of orange blossom water or grated lemon zest.
- Store covered at room temperature for up to 3 days or refrigerate for up to a week.
