Rhubarb Raspberry Upside-Down Cake Ingredients
For the Caramel Layer
• Unsalted Butter (258 grams total) – Provides richness and moisture. Substitute with a non-dairy butter if needed.
• Light Brown Sugar (100 grams) – Adds caramel flavor to the fruit layer. You can substitute with coconut sugar for a deeper taste.
For the Fruit Topping
• Fresh Rhubarb (450 grams) – Main fruit element; adds tartness. You can use plain rhubarb or blend with strawberries for a different flavor profile.
• Fresh Raspberries (170 grams) – Offers sweetness and vibrant color. Feel free to use frozen raspberries as a substitute.
• Granulated Sugar (100 grams) – Sweetens the fruit layer. Honey or maple syrup can replace this for a natural alternative.
• Cornstarch (10 mL) – Helps thicken fruit juices. Arrowroot can be used instead for a similar effect.
For the Cake Batter
• Bleached All-Purpose Flour (190 grams) – Forms the structure of the cake. For a gluten-free option, substitute with a 1:1 gluten-free flour blend.
• Ground Almonds (50 grams) – Adds moisture and a nutty flavor. Can replace with ground pistachios, or omit for a nut-free version.
• Baking Powder (6.25 mL) – Provides rise. Ensure it is fresh to avoid a denser cake.
• Kosher Salt (0.625 mL) – Enhances flavors. Halve the amount if using table salt.
• Pure Vanilla Extract (5 mL) – Adds depth. Almond extract can be used for a different flavor twist.
• Large Eggs (4) – Binds and provides structure. For an egg-free version, consider flax eggs (1 flax egg = 1 tbsp ground flaxseed + 2.5 tbsp water).

Step‑by‑Step Instructions for Rhubarb Raspberry Upside-Down Cake
Step 1: Preheat the Oven
Begin by setting your oven to 325°F (165°C) to preheat. While it warms up, prepare a 9-inch springform pan by greasing it with butter and lining the bottom with parchment paper to ensure easy removal later. This foundational step will help the Rhubarb Raspberry Upside-Down Cake bake evenly and easily.
Step 2: Prepare the Caramel Layer
In a medium saucepan over low heat, melt 100 grams of unsalted butter along with 100 grams of light brown sugar. Stir constantly until bubbly and smooth, which should take about 2-3 minutes. Pour this caramel mixture evenly into the prepared springform pan, creating a luscious base for your cake.
Step 3: Mix the Fruit Topping
In a mixing bowl, combine 450 grams of chopped fresh rhubarb, 170 grams of fresh raspberries, 100 grams of granulated sugar, and 10 mL of cornstarch. Gently toss the fruits together until they are coated fully, then let them sit for about 10-15 minutes. This process allows the fruits to release their natural juices, enhancing the flavor of the Rhubarb Raspberry Upside-Down Cake.
Step 4: Prepare the Cake Batter
In a separate bowl, whisk together 190 grams of bleached all-purpose flour, 50 grams of ground almonds, 6.25 mL of baking powder, and 0.625 mL of kosher salt. Set this aside. In a mixer, cream together the remaining butter and 100 grams of granulated sugar for about 3-4 minutes, until light and fluffy. Then, add 4 large eggs one at a time, mixing well between each addition, followed by 5 mL of pure vanilla extract.
Step 5: Combine Dry Ingredients and Sour Cream
Gradually incorporate the dry mixture into the butter-sugar-egg mixture, alternating with 80 mL of sour cream. Mix each addition just until combined, avoiding overmixing to keep the cake tender. This rich batter will add a delightful texture to the overall Rhubarb Raspberry Upside-Down Cake.
Step 6: Assemble the Cake
Once the fruit has macerated, layer it evenly over the caramel mixture in the pan. Gently spoon the prepared cake batter over the fruit, ensuring an even coverage. Smooth the top lightly with a spatula, taking care not to disturb the fruit layer beneath, as this will result in a beautiful presentation once inverted.
Step 7: Bake the Cake
Place the filled springform pan in your preheated oven and bake for 1 hour and 40-50 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean. The edges will be golden brown, signaling the Rhubarb Raspberry Upside-Down Cake is ready to be removed from the oven.
Step 8: Cool and Invert
Allow the cake to cool in the pan for 15 minutes. This resting time is crucial for ensuring a clean release. After cooling, run a knife around the edge of the pan, then carefully invert the cake onto a serving plate. The caramelized fruit layer should glisten, creating an enticing presentation for your guests.
Storage Tips for Rhubarb Raspberry Upside-Down Cake
Fridge: Store any leftovers in an airtight container in the refrigerator for up to 3 days. This helps maintain the cake’s moisture and flavor.
Freezer: If you want to keep the cake longer, wrap individual slices in plastic wrap and then aluminum foil, storing them in the freezer for up to 2 months.
Reheating: To enjoy your Rhubarb Raspberry Upside-Down Cake again, reheat slices gently in a preheated oven at 300°F (150°C) for about 10-15 minutes, or until warmed through.
Room Temperature: If serving the cake the same day it’s made, you can leave it uncovered at room temperature for a few hours, ensuring it’s consumed fresh and tasty!
Make Ahead Options
These Rhubarb Raspberry Upside-Down Cakes are a splendid option for meal prep enthusiasts! You can prepare the caramel layer and fruit topping up to 24 hours in advance, storing them separately in the refrigerator to keep them fresh. Just layer the caramel in the prepared pan, and refrigerate the macerated fruit until you’re ready to assemble. When it’s time to bake, simply make the cake batter and pour it over the chilled fruit. Finish the cake as directed and bake it straight from the fridge for just as delicious results. With this make-ahead option, you can save time and enjoy a delightful dessert with minimal effort on busy weeknights!

Rhubarb Raspberry Upside-Down Cake Recipe FAQs
What type of rhubarb should I use?
Absolutely! When selecting rhubarb, look for firm stalks that are bright in color without any dark spots or signs of wilting. The stalks should be crisp to the touch, indicating freshness. Avoid any that are limp or have blemishes, as these may affect the taste and texture of your Rhubarb Raspberry Upside-Down Cake.
How should I store leftovers?
To keep your cake fresh, store any leftovers in an airtight container in the refrigerator. It should stay delicious for up to 3 days. If you’ve got any slices left after that, you can always enjoy them warm by reheating in a 300°F (150°C) oven for about 10-15 minutes to bring back its lovely texture!
Can I freeze this cake?
Certainly! For longer storage, wrap individual slices of your Rhubarb Raspberry Upside-Down Cake tightly in plastic wrap and then in aluminum foil. This will keep it safe from freezer burn. You can freeze it for up to 3 months. When you’re ready to enjoy, simply thaw overnight in the refrigerator and reheat as needed.
What if my cake is too dense or soggy?
If you find your cake is dense or soggy, this could be due to overmixing the batter or having too much moisture from the fruits. Make sure to mix just until combined, and ensure your fruit mixture isn’t overly juicy before layering it in the pan. To fix a soggy cake, try baking it a little longer to allow excess moisture to evaporate, checking doneness with a toothpick in the center.
Are there any dietary considerations for this cake?
Yes! This Rhubarb Raspberry Upside-Down Cake can accommodate various dietary needs. For those with nut allergies, you can omit the ground almonds or substitute them with additional flour. If you’re looking for a gluten-free version, replace the all-purpose flour with a 1:1 gluten-free blend. For egg-free options, substitute the eggs with flax eggs (1 flax egg = 1 tbsp ground flaxseed + 2.5 tbsp water). Always check ingredient labels for allergies!
