Flourless Orange Pistachio Cake Recipe

Yield 8–10 slices

Prep Time 25 minutes

Bake Time 50–60 minutes

Ingredients:

• 2 medium oranges
• 1 ½ cups almond flour
• ¾ cup finely ground pistachios
• 4 large eggs
• ½ cup monk fruit sweetener or erythritol blend
• ¼ cup extra virgin olive oil
• 1 tsp vanilla extract
• 1 tsp baking powder
• Pinch of sea salt
• 1 tsp orange zest
• ½ tsp cardamom (optional but amazing)

Sugar-Free Citrus Glaze

• ½ cup powdered erythritol
• 2–3 tbsp fresh orange juice
• Tiny splash vanilla

Toppings

• Chopped pistachios
• Fresh orange slices
• Mint leaves
• Optional drizzle of sugar-free orange syrup

Step-by-Step Instructions

Step 1: Prepare the Oranges

1. Wash oranges thoroughly.
2. Boil them whole for 35–45 minutes until soft.
3. Cool slightly.
4. Remove seeds.
5. Blend entire oranges (including peel) into a smooth puree.

Why use whole oranges?

The peel gives:

• Deep citrus flavor
• Natural oils
• Moist texture
• Extra fiber

Step 2: Make the Batter

1. Preheat oven to 170°C / 340°F.
2. Grease an 8-inch cake pan.
3. Whisk eggs until slightly frothy.
4. Add sweetener, olive oil, vanilla, and orange puree.
5. Fold in:
   • almond flour
   • ground pistachios
   • baking powder
   • salt
   • zest
   • cardamom

The batter will look thicker than regular cake batter.

Step 3: Bake

1. Pour batter into pan.
2. Bake 50–60 minutes.
3. Top should become golden brown.
4. Toothpick should come out mostly clean.

Important

Because this cake is very moist, allow it to cool completely before slicing.

Step 4: Add Glaze & Toppings

1. Mix powdered erythritol with orange juice.
2. Drizzle over cooled cake.
3. Add pistachios and orange slices.

Pro Tips

1. Don’t Skip Boiling the Oranges

Raw peel tastes bitter. Boiling softens and sweetens it.

Use Fine Almond Flour

Coarse almond meal creates a heavier texture.

Cool Completely

The cake sets as it cools.

 Add Greek Yogurt for Extra Moisture

You can add:

• 2 tbsp plain Greek yogurt

This makes it softer and richer.

Storage

This cake actually tastes better the next day.
