Description

Sweet strawberry rhubarb upside-down cake brings summer’s most delightful flavors to your dessert table. Tangy rhubarb and luscious strawberries meld perfectly with a golden cake base, creating a memorable treat you’ll crave again and again.


Ingredients

Scale

Main Ingredients:

  • 5 cups rhubarb (fresh or frozen), sliced
  • 1 package (6 ounces) strawberry gelatin
  • 1 package white or yellow cake mix

Sweeteners:

  • 1/2 cup granulated sugar
  • 2 cups miniature marshmallows

Garnish:

  • Whipped topping (optional)

Instructions

  1. Prepare the oven to 350°F (175°C) and coat a 13×9-inch baking pan with grease to prevent sticking.
  2. Create a vibrant base by distributing rhubarb evenly across the bottom of the prepared pan.
  3. Generously dust strawberry gelatin over the rhubarb, followed by an even layer of sugar to enhance sweetness.
  4. Strategically place marshmallows across the sugared rhubarb, creating a fluffy underlayer.
  5. Mix the cake batter according to package instructions, ensuring a smooth and consistent texture.
  6. Carefully pour the prepared cake batter over the marshmallow layer, spreading it uniformly to cover the entire surface.
  7. Slide the pan into the preheated oven and bake for 40–45 minutes, checking doneness by inserting a toothpick into the center – it should emerge clean.
  8. Allow the cake to rest and cool for 10 minutes, then confidently invert onto a serving plate while still warm to preserve the structural integrity.
  9. Optional: Garnish with a dollop of whipped topping for an extra touch of indulgence before serving.

Notes

  • Ensure rhubarb is sliced uniformly to guarantee even cooking and consistent texture throughout the cake.
  • Replace marshmallows with almond slivers or coconut flakes for a healthier, nutty alternative that adds delightful crunch.
  • Swap regular gelatin with sugar-free version to reduce overall sugar content and make the dessert more diabetic-friendly.
  • Create a gluten-free option by using a gluten-free cake mix and double-checking all ingredient labels for potential wheat contamination.
