Ingredients
Tender, flourless cake packed with oranges, pistachios, and almond flour is topped with sticky orange and honey on top.
For the Cake:
- 2 cups almond flour
- 2 whole oranges
- ⅔ cup honey
- 3 large eggs
- ½ teaspoon baking soda
- 1 cup ground pistachios
- 1 teaspoon vanilla extract
For the Glaze:
- 2 tablespoons honey
- ½ cup fresh orange juice
How to Make Flourless Orange Pistachio Cake
Step 1: Prepare the Oranges
Take the oranges, rinse them well under running water, and toss them in a pot. Pour in enough water to cover them. Let them simmer gently for an hour.
Step 2: Blend the Oranges
Once boiled, drain the water and pop the oranges into a blender. Blend them until the texture is velvety smooth.
Step 3: Preheat Your Oven
Set your oven to 350°F (175°C) and lightly grease a 9-inch springform pan so the batter won’t stick.
Step 4: Mix Ingredients
In a large mixing bowl, combine the blended oranges, honey, eggs, almond flour, ground pistachios, baking soda, and vanilla extract. Stir everything together until smooth.
Step 5: Bake the Cake
Pour the mixture into the greased pan and bake for around an hour. Keep an eye on it—if the top starts browning too early, loosely cover it with foil. It’s done when a toothpick comes out clean.
Step 6: Prepare the Glaze
Combine honey and orange juice in a small pot. Heat it up until it boils; then lower the heat and simmer it down to half its original amount. Let it cool afterward.
Step 7: Finish Up
Once the cake isn’t too hot, apply the glaze over the top using a brush. Let it cool completely before taking it out of the pan to enjoy.
How to Serve Flourless Orange Pistachio Cake
Serving Flourless Orange Pistachio Cake can be a delightful experience, enhancing its rich flavors and textures. Here are some creative ways to present this beautiful dessert.
Pair with Fresh Berries
- Adding a mix of fresh berries like strawberries, blueberries, and raspberries can provide a vibrant contrast to the cake’s sweetness. Their tartness balances the rich orange and honey flavors perfectly.
Accompany with Whipped Coconut Cream
- A dollop of whipped coconut cream can add a creamy texture that complements the cake’s moistness. Simply whip chilled coconut cream until fluffy for an easy topping.
Serve with a Dusting of Powdered Sugar
- A light dusting of powdered sugar not only adds elegance but also enhances the visual appeal of your cake. This simple touch makes it look more inviting.
Garnish with Sliced Oranges
- Thinly sliced oranges on top or around the plate can enhance the citrus flavor and make for an eye-catching presentation. Use edible flowers for extra flair.
Drizzle with Extra Honey
- A drizzle of honey over each slice before serving brings out the sweetness and adds a sticky glaze that enhances the overall taste experience.
How to Perfect Flourless Orange Pistachio Cake
To ensure your Flourless Orange Pistachio Cake turns out perfectly every time, follow these helpful tips.
Use Fresh Oranges – Fresh oranges yield better flavor compared to canned or frozen options. Their zest will also enhance the aroma.
Measure Almond Flour Carefully – Too much almond flour can lead to a dense cake. Use a kitchen scale for accuracy if possible.
Don’t Overmix – Stir just until combined; overmixing can create a tougher texture. The batter should be smooth but not overly beaten.
Check for Doneness – Instead of relying solely on time, use a toothpick inserted into the center. It should come out clean when the cake is perfectly baked.
Cool Before Glazing – Allowing the cake to cool slightly before adding the glaze helps it set without running off too quickly.
Best Side Dishes for Flourless Orange Pistachio Cake
Pair your Flourless Orange Pistachio Cake with these delicious side dishes to elevate your dessert experience.
- Greek Yogurt Parfait – Layer Greek yogurt with granola and fruits for a creamy and crunchy contrast.
- Citrus Salad – A refreshing salad made from mixed citrus fruits brightens the palate and complements the cake’s flavors.
- Chia Seed Pudding – This nutritious pudding can be flavored with vanilla or orange zest, offering a creamy counterpart to your dessert.
- Honey Roasted Nuts – Sweet and crunchy nuts provide a delightful texture contrast while enhancing nutty flavors in the cake.
- Fruit Sorbet – A scoop of fruit sorbet adds chilliness and is perfect for cleansing the palate after enjoying your rich cake.
- Herbed Couscous Salad – Light and fluffy couscous tossed with herbs and lemon makes for an unexpected yet tasty side that pairs well.
Common Mistakes to Avoid
When making the Flourless Orange Pistachio Cake, it’s essential to sidestep common pitfalls to ensure a perfect dessert every time.
- Using unblended oranges: Make sure to blend the cooked oranges until smooth. This ensures that your cake has a uniform texture and rich flavor.
- Skipping the greasing step: Always grease the springform pan. This prevents the cake from sticking and makes it easier to remove after baking.
- Overmixing the batter: Mix just until combined. Overmixing can lead to a denser cake than desired, affecting its lightness and fluffiness.
- Ignoring baking time: Keep an eye on your cake as it bakes. If the top darkens too quickly, cover it with foil. This helps in achieving even cooking without burning.
- Not letting it cool: Allow your cake to cool completely before removing it from the pan. This prevents cracks and helps maintain its shape.
