Directions

1. Boil the Oranges:

Place the whole unpeeled oranges in a saucepan and cover with water.
Bring to a boil, then drain completely to reduce bitterness.
Refill with fresh water, bring to a boil again, then simmer for about 40 minutes, until the oranges are soft all the way through.
While they cook, start prepping your cake tin.

2. Prep the Cake Tin:

Line the bottom of a 23 cm / 9 inch springform cake pan with baking paper.
Close the springform around the paper to secure it in place.
Preheat the oven to 180°C (350°F).

3. Blend the Oranges with Eggs:

Once the oranges are soft, remove them from the water and allow to cool slightly.
Cut them in half and remove any seeds.
In a blender, purée the whole oranges (peel and all) together with the eggs into a smooth mixture.

4. Mix the Batter:

In a large mixing bowl or stand mixer, add:
- Almond flour
- Cane sugar
- Salt
- Baking soda
Pour in the orange–egg purée.
Blend or stir everything together until you have a smooth, uniform batter.

5. Bake the Cake:

Pour the batter into your prepared springform tin.
Bake in the preheated oven for 35–40 minutes, or until the top is golden and there’s no wobble when you gently shake the pan.

6. Cool Completely:

Remove the cake from the oven and let it cool fully in the tin before removing it and adding toppings.

7. Prepare the Mascarpone Cream:

In a small bowl, combine:
- 200 g mascarpone
- 2 tablespoons unrefined sugar
- 1 teaspoon vanilla sugar
Mix until smooth and creamy.

8. Decorate:

Spread the mascarpone cream evenly over the top of the cooled cake.
Add thin slices of orange (raw or lightly candied).
Top with fresh mint sprigs for color and fragrance.
Dust with cinnamon powder.
Add a few cinnamon sticks for a rustic, festive look.

Storage

Store the undecorated cake in an airtight container at room temp for up to 3 days.
With topping, refrigerate and consume within 3–4 days.
Cake can be frozen (without topping) for up to 2 months.
