Ingredients You’ll Need
These ingredients are straightforward yet essential, balancing fruit, sweetness, and texture to make this cake truly exceptional. Every item plays its part, from the ripe peaches and plums that bring vibrant color and juiciness to the almond flour that imparts a gentle crunch beneath the soft crumb.
- 3/4 lb. (340 g) peaches and plums, sliced evenly: Use ripe fruit to ensure optimal sweetness and juiciness, slicing evenly for consistent caramelization.
- 3/4 cup (170 g) unsalted butter, divided: Butter provides richness and helps create that irresistible caramel coating.
- 1 1/4 cups (250 g) light brown sugar, divided: The light brown sugar adds deep molasses notes and moisture to the cake.
- 2 Tbsp. (30 ml) maple syrup or agave: Adds natural sweetness and complexity to the caramel layer.
- 3/4 tsp. (4 g) kosher salt, divided: Balances sweetness and brightens up the flavors.
- 1 cup (120 g) all-purpose flour: The base flour that gives structure to the cake.
- 1/2 cup (50 g) almond flour: Adds subtle nuttiness and moist crumb.
- 1 tsp. (5 g) baking powder: Helps the cake rise evenly.
- 1/2 tsp. (2 g) baking soda: Works with baking powder to give a tender texture.
- 2 tsp. (10 ml) vanilla extract: Brings warm, comforting aroma and flavor.
- 1/2 cup (120 g) silken tofu: Keeps the cake moist and adds richness without heaviness.
- 1/2 cup (120 g) sour cream: Contributes tanginess and tender crumb texture.
How to Make Peach Plum Upside Down Cake Recipe
Step 1: Prepare Your Pan and Oven
Kick off your baking adventure by preheating your oven to 350°F (175°C). Preparing your 9-inch round baking pan properly with parchment paper and a light grease ensures that your finished cake will release smoothly without a fuss. This initial step is crucial for a flawless upside down cake flip later on.
Step 2: Arrange Your Fruit
Evenly sliced peaches and plums are the stars of this cake’s beautiful bottom layer. Carefully place them in a single layer in your baking pan, allowing a little space between slices. This space helps the batter spread evenly and ensures that each slice gets a chance to caramelize to perfection.
Step 3: Make the Caramel Glaze
Melt together a quarter cup of butter, a quarter cup of brown sugar, your maple syrup or agave, and a pinch of kosher salt in a small saucepan over medium heat. Stir this mixture until it’s glossy and smooth. This rich, golden caramel will soak into the fruit, infusing every bite with decadence.
Step 4: Cream Butter and Sugar
In a separate large bowl, use an electric mixer to beat half a cup of butter with one cup of brown sugar until the mixture turns pale and fluffy, about five minutes. This process is key for a light and airy crumb that will perfectly complement your caramelized fruit layer.
Step 5: Incorporate the Wet Ingredients
Gently mix in the silken tofu, sour cream, and vanilla extract to your creamed butter and sugar. Stir just until combined — over-mixing can weigh down your batter, so treat this step delicately to keep the texture light and moist.
Step 6: Combine Dry Ingredients
Whisk together the all-purpose flour, almond flour, baking powder, baking soda, and remaining kosher salt in another bowl. Gradually fold this dry mix into your wet ingredients, stirring only until there are no visible streaks of flour. This tender balance ensures your cake will rise beautifully without becoming dense.
Step 7: Assemble Your Cake
Pour the warm caramel glaze evenly over the bottom of your lined pan. Layer the arranged peaches and plums on top of the caramel, then carefully pour your batter over the fruit. Use a spatula to gently spread the batter into an even layer without disturbing the fruit below. This careful layering is what gives this cake its signature stunning look after baking.
Step 8: Bake Your Cake
Slide your pan into the preheated oven and bake for approximately 35 minutes. Keep an eye out for the telltale signs: edges pulling away from the pan and a top that springs back lightly when you press it. This indicates your cake is perfectly baked with a moist crumb inside.
Step 9: Cool and Invert
Let the cake cool in the pan for 10 minutes—this resting period allows the caramel to set slightly. Run a sharp knife around the edges to loosen the cake, then carefully invert it onto a heatproof serving plate. If it sticks initially, patience is your ally; wait another 5 minutes and try again for a beautiful glossy fruit topping reveal.
How to Serve Peach Plum Upside Down Cake Recipe

Garnishes
To take your Peach Plum Upside Down Cake Recipe to the next level, consider garnishing with a light dusting of powdered sugar or a handful of toasted almond slivers for some crunch. A dollop of whipped cream or a scoop of vanilla ice cream adds a creamy contrast to the caramelized fruit’s natural sweetness.
Side Dishes
This cake pairs wonderfully with a cup of fragrant Earl Grey tea or a bold coffee to balance out its sweet richness. For a brunch setting, a simple green salad with a tangy vinaigrette can provide a refreshing counterpoint to the dessert’s buttery richness.
Creative Ways to Present
For a stunning presentation, garnish your cake plate with fresh peach and plum slices or edible flowers. Try serving individual slices with a drizzle of additional warmed maple syrup or a splash of fruit liqueur to impress your guests with both flavor and flair.
Make Ahead and Storage
Storing Leftovers
Store any leftover Peach Plum Upside Down Cake Recipe tightly wrapped in plastic wrap or in an airtight container at room temperature for up to two days. Keeping it covered preserves the moistness and prevents it from drying out.
Freezing
If you want to enjoy this cake later, you can freeze it wrapped firmly in plastic wrap and then in aluminum foil for up to three months. Thaw overnight in the refrigerator and bring to room temperature before serving for the best texture.
Reheating
To revive the freshly baked taste, warm slices gently in a low oven or microwave for short bursts. This softens the cake and enhances the luscious caramel flavors, making every bite taste like it’s just out of the oven.
FAQs
Can I use other fruits instead of peaches and plums?
Absolutely! This Peach Plum Upside Down Cake Recipe is versatile. You can substitute with fruits like nectarines, cherries, or even apples for a different twist. Just be sure to slice evenly and choose ripe, juicy fruits for optimal caramelization.
Is silken tofu necessary in the recipe?
The silken tofu adds moisture and richness while keeping the cake tender without using eggs. If you are not a fan, you can experiment with alternatives such as yogurt or mashed banana, but expect slight changes to texture and flavor.
How do I know when the cake is fully baked?
Look for the edges to pull away slightly from the pan and test the top with a gentle press—it should spring back. If you’re still unsure, insert a toothpick into the center; it should come out clean or with a few moist crumbs, not wet batter.
Can I make this cake gluten-free?
To adapt this Peach Plum Upside Down Cake Recipe for gluten-free diets, substitute the all-purpose flour with a gluten-free flour blend. Adding xanthan gum may help replicate the texture of regular flour, but keep a close eye on baking times as this can vary.
What’s the best way to slice and serve the cake?
Use a sharp serrated knife to gently cut through the tender cake, wiping the knife clean between slices for neat portions. Serving slightly warm allows the caramel and fruit flavors to shine, creating the best experience.
Final Thoughts
I can’t recommend this Peach Plum Upside Down Cake Recipe enough for anyone who loves a dessert that’s simultaneously simple and show-stopping. The combination of caramelized stone fruits and tender cake is something magical that will have everyone asking for seconds. Give it a try, and I promise it will become one of your most treasured recipes for seasons to come.

- 1 tsp. (5 g) baking powder
- 1/2 tsp. (2 g) baking soda
- 1/2 tsp. (3 g) kosher salt
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line a 9-inch round baking pan with parchment paper and lightly grease both the pan and parchment. This helps in easy removal of the cake once baked.
- Slice and arrange fruit: Slice peaches and plums evenly. Arrange a single layer of these slices at the bottom of the prepared pan, leaving slight spaces between fruit to allow batter spreading.
- Make caramel sauce: In a small saucepan over medium heat, melt 1/4 cup (57 g) butter with 1/4 cup (50 g) light brown sugar, 2 Tbsp. (30 ml) maple syrup or agave, and 1/4 tsp. (1 g) kosher salt. Stir continuously until the mixture is smooth and combined.
- Cream butter and sugar: In a mixing bowl, beat 1 cup (113 g) softened butter with 1 cup (200 g) light brown sugar using an electric mixer at medium speed until light and creamy, about 5 minutes. Scrape bowl sides as needed.
- Add wet ingredients: Blend in the silken tofu (1/2 cup/120 g), sour cream (1/2 cup/120 g), and vanilla extract (2 tsp/10 ml) into the creamed butter and sugar, mixing gently until just combined to maintain a light texture.
- Combine dry ingredients: In another bowl, whisk together all-purpose flour (1 cup/120 g), almond flour (1/2 cup/50 g), baking powder (1 tsp/5 g), baking soda (1/2 tsp/2 g), and remaining kosher salt (1/2 tsp/3 g).
- Fold dry into wet mixture: Gradually fold the dry ingredients into the wet mixture, stirring only until just combined without over-mixing.
- Assemble cake: Pour the prepared caramel into the bottom of the lined pan. Evenly spread the arranged fruit slices over the caramel. Carefully pour the batter over the fruit layer, spreading it evenly to cover the fruit.
- Bake the cake: Place the cake in the preheated oven and bake for about 35 minutes, until the edges pull away from the pan and the top springs back when lightly touched.
- Cool and invert: Remove the cake from the oven and let it cool in the pan for 10 minutes. Run a knife around the edges to loosen, then invert the cake onto a heatproof serving plate. If it sticks, cool an additional 5 minutes before trying again.
Notes
- Ensure fruit slices are evenly cut for uniform baking.
- Do not overmix batter to keep cake tender and moist.
- Use a high-quality parchment paper to avoid sticking during inversion.
- Allow cake to cool sufficiently before inverting to prevent breakage.
- Silken tofu adds moisture and a slight protein boost without dairy heaviness.
- Adjust sweetness by using maple syrup or agave according to preference.
