Ingredients
Makes one 9-inch round cake
- 2 cups (200 g) almond meal (finely ground almonds)
- 3/4 cup (90 g) shelled pistachios, finely chopped (plus extra for topping)
- 1 cup (200 g) granulated sugar
- 4 large eggs at room temperature
- Zest of 2 oranges and 1/4 cup fresh orange juice
- 1/4 cup neutral oil (sunflower or light olive oil)
- 1 tsp baking powder
- 1/4 tsp fine salt
- 1 tsp pure vanilla extract
- Confectioners’ sugar for dusting or a simple orange glaze (optional)
For a citrus glaze: 1/2 cup confectioners’ sugar + 1–2 tbsp orange juice
Step-by-step instructions
- Preheat and prep: Preheat oven to 350°F (175°C). Grease a 9-inch round springform pan and line the bottom with parchment for easy release.
- Mix dry ingredients: In a bowl, combine the almond meal, chopped pistachios, baking powder, and salt. Stir until evenly distributed.
- Whisk eggs and sugar: In a large mixing bowl, whisk the eggs and granulated sugar vigorously until pale and slightly thickened (about 3–5 minutes by hand or 2–3 minutes with a mixer).
- Add flavorings and oil: Stir in orange zest, orange juice, vanilla extract, and oil until well combined.
- Fold in dry mix: Gently fold the almond-pistachio mixture into the egg mixture. Mix until no large streaks remain, being careful not to deflate the batter.
- Bake: Pour batter into the prepared pan, smooth the top, and sprinkle a few chopped pistachios on top. Bake 30–40 minutes, or until the top is golden and a skewer inserted into the center comes out mostly clean with a few moist crumbs.
- Cool and finish: Let the cake cool in the pan for 10 minutes, then release the springform and cool completely on a rack. Dust with confectioners’ sugar or drizzle with the orange glaze if you like.
Tips for success
- Use room-temperature eggs: They blend more easily and help achieve a lighter texture.
- Measure nuts correctly: For consistent results, weigh the almond meal and pistachios. Finely ground almond meal makes the cake tender; avoid too-coarse pieces.
- Don’t overmix: Fold gently so you keep some air in the batter.
- Test doneness carefully: Flourless cakes stay moist; look for a golden top and a mostly clean skewer rather than bone-dry crumbs.
- For extra flavor, toast the pistachios lightly before chopping — this deepens the nutty aroma.
Possible variations
- Gluten-free twist: This Flourless Orange Pistachio Almond Cake is naturally gluten-free, but you can swap half the almond meal for finely ground hazelnuts for a different profile; see a related gluten-free orange almond cake for similar ideas.
- Streusel topping: For a crunch, mix 1/3 cup almond meal, 2 tbsp brown sugar, 2 tbsp butter (or dairy-free alternative), and a pinch of salt. Crumble over the batter before baking.
- Extra citrus: Add 1 tsp orange blossom water or 1 tbsp limoncello substitute (non-alcoholic orange syrup) to amplify aroma.
- Different nut mix: Replace pistachios with chopped walnuts or hazelnuts, inspired by this Italian almond and orange cake inspiration.
- Breakfast option: Crumble leftover slices over yogurt, or serve warm with honey and ricotta for a brunch twist — similar comfort can be found in flourless cottage cheese pancakes.
Storage recommendations
- At room temperature: Store in an airtight container for up to 2 days.
- In the fridge: Keep wrapped or in a container for up to 5 days; bring to room temperature before serving for best texture.
- Freezing: Wrap tightly and freeze for up to 2 months. Thaw in the refrigerator overnight and warm gently before serving. For another make-ahead dessert, consider the flourless sweet potato ginger cake for seasonal variety.
