A gorgeous flipped cake that showcases the natural charm of citrus, forming a gradient pattern that's just as eye-catching as it is tasty. Different orange types blend to make sunset-like colors, while peanut butter brings surprising richness to the soft cake underneath.
I came up with this cake during winter when my farmers market had an amazing display of orange varieties. The way the fruit turns golden brown while baking creates this beautiful stained-window look that always wows my dinner guests.
Key Ingredients Breakdown
- Orange varieties: Try to pick ones with matching sizes so they cook evenly
- Eggs not from the fridge: They'll help your cake rise properly
- Straight-up peanut butter: Gives you the yummiest result
- Just-squeezed citrus juice and zest: Makes all the difference for a zingy flavor
- Good mascarpone cheese: Creates the creamiest topping
After lots of trial runs, I've found that cutting oranges with a razor-sharp mandoline gives you those super thin, consistent slices you need for the perfect design.
Building Your Beautiful Cake
- Fruit Prep
- Cut oranges with care and set them up in color order for that wow factor.
- Syrup Making
- Cook citrus pieces slowly to keep their shape while they soak up flavor.
- Mix Formation
- Combine everything gently to keep the cake fluffy when it's done.
- Putting It Together
- Place fruit exactly right for the most beautiful look.
- Finishing Moves
- Pour warm syrup bit by bit so it soaks in evenly.
The chef who taught me always said the secret to arranging citrus perfectly is to start in the middle and work your way out in circles.
Tasty Companions
This cake tastes amazing with a cup of Earl Grey or some bubbly prosecco that brings out the citrus flavors.

Inventive Twists
Try mixing up the citrus by using grapefruit with Meyer lemon, or swap in almond butter instead of peanut butter.
Keeping It Fresh
You can keep the unfrosted cake out on the counter for a couple days, just add the mascarpone right before you serve it.
From my many years making upside-down cakes, I've discovered that taking your time during cooling means the fruit stays put when you turn it over.
Managing Heat
- Get mascarpone to the right room temp for a smooth topping
- Watch the syrup heat carefully so your citrus doesn't burn
- Set your cake on a wire rack so air moves around it while cooling
I've noticed through tons of baking that getting temperatures just right is what turns an okay cake into an amazing one.
Fixing Common Problems
- When fruit gets stuck: Heat the bottom quickly over low flame
- If your cream gets lumpy: Add more cold cream slowly while mixing
- For too-fast browning: Cover loosely with foil during baking
Display Suggestions
- Add fresh herbs like mint or thyme around the edges
- Tuck tiny edible flowers between the citrus pieces
- Make fancy spoon-shaped mounds with the mascarpone cream
