Step-by-Step Instructions
Baking this Flourless Orange Pistachio Cake is a journey of love and patience. Follow these steps carefully, and soon you’ll have a magnificent creation ready to share with your loved ones. Each step is a small act of care, bringing us closer to that perfect slice.

- Prepare the Oranges: Wash the oranges thoroughly. Place them in a large pot, cover with cold water, and bring to a boil. Reduce heat and simmer gently for 1 ½ to 2 hours, or until very soft. Drain the oranges, let them cool completely, then cut them in half and remove any seeds.
- Puree the Oranges: Once cool, place the cooked orange halves (peel and all!) into a food processor. Process until you have a smooth puree. This unique step is what gives our Flourless Orange Pistachio Cake its incredible moisture and intense orange flavor.
- Preheat Oven & Prepare Pan: Preheat your oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan with parchment paper. Lightly grease the sides too.
- Prepare Pistachios: If not already ground, pulse the shelled pistachios in a food processor until finely ground but not pasty. Set aside.
- Whip Eggs and Sugar: In a large mixing bowl, using an electric mixer, beat the eggs and granulated sugar on high speed for 8-10 minutes, until the mixture is very pale, thick, and greatly increased in volume. This creates the essential airy structure for our flourless orange pistachio cake.
- Combine Wet Ingredients: Gently fold the orange puree and vanilla extract into the whipped egg mixture. Be careful not to deflate the air you’ve just incorporated.
- Fold in Dry Ingredients: In a separate bowl, whisk together the almond flour, ground pistachios, baking powder, and salt. Gradually fold this dry mixture into the wet ingredients until just combined. Overmixing can toughen the cake, so be gentle.
- Pour and Bake: Pour the batter evenly into the prepared springform pan. Bake for 50-60 minutes, or until the top is golden brown and a skewer inserted into the center comes out clean. The cooking time for a Flourless Orange Pistachio Cake can vary depending on your oven.
- Cool: Allow the cake to cool in the pan for about 20-30 minutes before releasing the springform sides. Transfer the cake to a wire rack to cool completely. This is crucial for maintaining its structure.
- Garnish and Serve: Once completely cool, dust with powdered sugar, sprinkle with extra chopped pistachios, or adorn with candied orange slices. Slice and serve this magnificent Flourless Orange Pistachio Cake with pride!

Pro Tips for Success
Even the simplest recipes benefit from a few expert insights. These tips will help ensure your Flourless Orange Pistachio Cake turns out perfectly every time, worthy of passing down through generations.

- Boil Oranges Thoroughly: The long boiling time is vital. It softens the peel, mellows bitterness, and makes the oranges easily pureed, contributing to the cake’s incredible moisture. Don’t rush this step for your flourless orange pistachio cake.
- Egg Whipping is Key: Whipping the eggs and sugar until pale and thick incorporates a lot of air, which is the primary leavening for this flourless orange pistachio cake. This step replaces the lift usually provided by gluten.
- Gentle Folding: When adding the orange puree and then the dry ingredients, use a light hand. Overmixing will deflate the batter, resulting in a dense cake. Fold until just combined.
- Don’t Open Oven Door: Avoid opening the oven door too frequently during the first 40 minutes of baking. This can cause the cake to sink.
- Cool Completely: This delicate cake needs to cool fully before slicing. Attempting to move or slice it while warm can cause it to crumble. Patience is a virtue here!
- Taste Test Your Puree: After pureeing the oranges, taste a tiny bit. If your oranges were particularly bitter, you might want to add an extra tablespoon of sugar to the batter.
Storage & Reheating Tips
This Flourless Orange Pistachio Cake is so delightful, you’ll want to savor every last crumb. Proper storage ensures its freshness and flavor endure. Here’s how to keep your cake tasting its best:

- Room Temperature: Store the cake, loosely covered, at room temperature for up to 2-3 days. Its high moisture content helps it stay fresh.
- Refrigeration: For longer storage, cover the cake tightly with plastic wrap and refrigerate for up to 5 days.
- Freezing: This cake freezes beautifully! Wrap individual slices or the entire cake tightly in plastic wrap, then in foil. Freeze for up to 3 months. Thaw in the refrigerator overnight or at room temperature for a few hours.
- Reheating: While delicious at room temperature, a quick warm-up can sometimes enhance the flavors. Gently warm individual slices in the microwave for 10-15 seconds, or in a preheated oven (300°F/150°C) for 5-10 minutes.
