Instructions
Crafting this Rhubarb Upside Down Cake is a straightforward process that yields spectacular results. The key is in the layering and the patient baking.
- Prepare the Pan and Rhubarb Base: Begin by spreading the sliced rhubarb evenly across the bottom of your 9×13 inch baking pan. Ensure it forms a relatively uniform layer.
- Add the Sugar Layer: Sprinkle the 1 ½ cups of granulated sugar evenly over the rhubarb. This sugar will caramelize beautifully during baking, creating a luscious topping.
- Incorporate the Raspberry Jell-O: Sprinkle the contents of the 3-ounce package of raspberry Jell-O gelatin over the sugar layer. This adds a beautiful color and a subtle fruity note.
- Distribute the Marshmallows: Spread the 3 cups of miniature marshmallows evenly over the entire surface. As the cake bakes, these will melt and merge with the rhubarb and sugar, creating a sticky, delightful layer.
- Prepare the Cake Batter: In a large mixing bowl, combine the yellow cake mix, 3 eggs, ⅓ cup oil, and 1 ⅓ cups water. If your cake mix package specifies different quantities for eggs, oil, or water, please follow those instructions for the best cake texture. Whisk or beat the ingredients together until the cake batter is smooth and well combined, free of any lumps.
- Pour the Cake Batter: Carefully pour the prepared cake batter evenly over the rhubarb mixture in the baking pan. Try to cover the marshmallows and fruit mixture as completely as possible.
- Bake the Cake: Preheat your oven to 350°F (175°C). Place the pan in the preheated oven and bake for approximately 60 minutes. The cake is done when it tests done. To check for doneness, insert a wooden skewer or toothpick into the center of the cake. If it comes out clean, the cake is ready. If there is wet batter, continue baking for a few more minutes and test again.
- Cool and Invert: Once baked, remove the cake from the oven. Let it cool in the pan for about 10-15 minutes. This cooling period is crucial for the caramel to set slightly, making inversion easier.
- Serve: To serve, place a serving plate upside down over the warm cake pan. With a confident and swift motion, invert the pan onto the plate. The rhubarb and caramel topping should gracefully slide out, creating a beautiful presentation. Cut the cake into pieces and serve warm.
Expert Tips & Tricks
Achieving that perfect upside-down cascade requires a little finesse. Ensure your rhubarb is sliced evenly; too thick and it might not soften enough, too thin and it could turn to mush. When preparing your cake batter, avoid overmixing, as this can lead to a tough cake. The cooling period before inversion is key – too soon and the topping will be too runny, too late and it might stick. If you find a few pieces of fruit or marshmallow are reluctant to release from the pan, don’t fret! Simply use a spatula to gently coax them onto the cake.
Serving & Storage Suggestions
This Rhubarb Upside Down Cake is utterly divine served warm, allowing the caramelized fruit and gooey marshmallows to shine. A dollop of freshly whipped cream, a scoop of vanilla bean ice cream, or even a drizzle of crème fraîche makes for a truly indulgent accompaniment. If you happen to have any leftovers, which is unlikely once this cake makes its appearance, cover the cake tightly with plastic wrap or place it in an airtight container. It can be stored at room temperature for up to 2 days, though refrigeration is recommended for longer storage, up to 4-5 days. To reheat, gently warm individual slices in the microwave or a low oven.

Variations & Substitutions
While the classic raspberry Jell-O provides a beautiful color and flavor synergy, feel free to experiment! A strawberry Jell-O would also be a delightful choice, offering a slightly different sweet and tangy profile. For those who prefer a more pronounced fruit flavor, you could omit the Jell-O and increase the rhubarb slightly, perhaps adding a splash of orange juice or lemon zest to the fruit mixture before baking. If you don’t have yellow cake mix, a white cake mix will also work beautifully.
FAQs
Q: Can I use frozen rhubarb for this cake?
A: Yes, you can use frozen rhubarb. If using frozen rhubarb, ensure it is thawed and drained very well to remove excess moisture before slicing and using it in the recipe.
Q: My cake seems to be browning too quickly. What should I do?
A: If the top of your cake is browning too rapidly before the inside is cooked through, you can loosely tent the pan with aluminum foil. This will help shield the top from direct heat while allowing the cake to finish baking.
Q: What is the best way to ensure the caramel doesn’t stick to the pan?
A: Allowing the cake to cool for about 10-15 minutes after baking is crucial. This brief cooling period allows the caramelized sugar to set slightly, making it easier for the topping to release cleanly when inverted.
Q: Can I make this cake ahead of time?
A: While this cake is best enjoyed fresh, you can bake it a few hours in advance and keep it covered at room temperature. For longer storage, follow the storage suggestions provided.
Q: Why do you use miniature marshmallows?
A: Miniature marshmallows melt more evenly and quickly, creating a smoother, more consistent layer of gooey sweetness when they caramelize with the rhubarb and sugar.
