Ingredients

Scale

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
2 tablespoons honey
½ cup fresh orange juice

Instructions

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.
Once boiled, drain the water and pop the oranges into a blender. Blend them until the texture is velvety smooth.

Set your oven to 350°F (175°C) and lightly grease a 9-inch springform pan so the batter won't stick.
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.

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.
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.

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.

Frequently Asked Questions

Can I make this cake without pistachios?

How long does the whole orange need to be boiled?

Simmer the whole orange for about 2 hours until it is completely soft and tender. This process is essential for creating the moist, flavorful puree that forms the base of the Flourless Orange Pistachio Cake.

Why is my cake dense or gummy?
