Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9x13-inch cake pan.
  2. Spread 3 cups of mini marshmallows evenly on the bottom of the prepared pan.
  3. In a small saucepan, combine 3 cups of rhubarb, 1 cup of sugar, and 1 1/2 cups of water. Cook over heat until the mixture is heated through.

  10. Top with Cool Whip before serving, if desired.

Tips & Substitutions

For a lighter version, consider using sugar substitutes or a reduced-sugar cake mix. You can replace rhubarb with other tart fruits like cranberries or chopped apples for a different flavor profile. Ensure the rhubarb is tender before incorporating it into the mixture for the best texture. If you want to enhance the flavor, add a teaspoon of vanilla extract to the cake batter.

Serving Suggestions

This cake is delightful on its own, but you can enhance it by serving it with a scoop of vanilla ice cream or a dollop of whipped cream. For a refreshing drink pairing, consider serving it with a glass of Citrus-Mint Tea Cooler. It also makes a lovely dessert for gatherings, alongside dishes like Marinated Asparagus for a well-rounded meal.

Storage & Reheating

Store any leftover cake in an airtight container in the refrigerator for up to 3 days. To reheat, place individual slices in the microwave for 15-20 seconds or until warmed through. If the cake seems dry after refrigeration, adding a dollop of Cool Whip can help restore moisture and flavor upon serving.

Frequently Asked Questions

Can I use frozen rhubarb instead of fresh?

Yes, frozen rhubarb can be used in this recipe. Just ensure to thaw and drain any excess moisture before cooking. This will help maintain the right consistency in your cake, preventing it from becoming too soggy.

What should I do if my cake sinks in the middle?

If your cake sinks, it may be due to underbaking or too much moisture in the batter. Ensure you bake until a toothpick comes out clean and avoid overmixing the batter, which can incorporate excess air and lead to collapse.

Can I make this cake ahead of time?

Absolutely! You can prepare the cake a day in advance. After baking, let it cool completely, then store it in the refrigerator. Just remember to invert it onto a serving plate before serving, and add the Cool Whip just before presenting.
