A stunning upside-down cake that celebrates the natural beauty of citrus fruits, creating an ombre effect that's as visually striking as it is delicious. The combination of different orange varieties creates a gradient of sunset colors, while peanut butter adds unexpected depth to the tender cake beneath.
I first created this cake during citrus season when my local market had a stunning array of orange varieties. The way the fruit caramelizes during baking creates an almost stained-glass effect that never fails to impress guests.
Essential Ingredients Guide
- Orange varieties: Should be similar in size for even cooking
- Room temperature eggs: Ensure proper cake structure
- Natural peanut butter: Provides the best flavor and texture
- Fresh citrus juice and zest: Crucial for bright flavor
- Quality mascarpone cheese: Makes the cream silky smooth
Through extensive testing, I've discovered that slicing the oranges with a sharp mandoline creates the most consistent, paper-thin slices needed for the perfect design.
Creating Your Cake
- Citrus Preparation
- Slice oranges carefully and arrange by color gradient for visual impact.
- Syrup Development
- Simmer citrus slices gently to preserve their shape while infusing flavor.
- Batter Creation
- Mix ingredients carefully to maintain lightness in the final cake.
- Assembly Process
- Layer fruit precisely for the most striking presentation.
- Final Touches
- Apply warm syrup gradually to ensure even absorption.
My pastry chef mentor taught me that the key to perfect citrus arrangement lies in starting from the center and working outward in concentric circles.
Perfect Pairings
Serve this cake with Earl Grey tea or a glass of prosecco to complement the citrus notes.

Creative Variations
Experiment with different citrus combinations like grapefruit and Meyer lemon, or try almond butter instead of peanut butter.
Storage Success
Keep unfrosted cake at room temperature for up to two days, adding mascarpone cream just before serving.
After years of perfecting upside-down cakes, I've learned that patience during the cooling process ensures the fruit layer remains intact when unmolding.
Temperature Control
- Keep mascarpone at exact room temperature for smooth cream
- Monitor syrup temperature to avoid burning citrus
- Let cake cool on a wire rack for proper air circulation
I've learned through countless bakings that temperature precision makes the difference between good and exceptional results.
Troubleshooting Common Issues
- If fruit sticks to pan: Warm bottom briefly over low heat
- If cream curdles: Whisk in more cold cream slowly
- If cake browns too quickly: Tent with foil while baking
Presentation Tips
- Garnish with fresh herbs like mint or thyme
- Add edible flowers between citrus slices
- Create height with mascarpone cream quenelles
