Ingredients
Tender, flourless cake packed with oranges, pistachios, and almond flour, then topped with sticky orange and honey on top.
For the Base:
- 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 Together
Mix the blended oranges, honey, eggs, almond flour, ground pistachios, baking soda, and vanilla extract in a large mixing bowl. Stir everything together until the mixture looks 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: Glaze Your Cake
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.
