Ingredients for Topping and Cake

• 1 cup rhubarb – sliced into ½-inch chunks (no peeling necessary, just trim the ends)
• 1 cup strawberries – hulled and halved (pick firm berries so they hold up well)
• ¾ cup granulated sugar – just enough to cut the tartness of the rhubarb
• 2 tablespoons unsalted butter – melted
• 1½ cups all-purpose flour – spooned and leveled for accuracy
• 1 teaspoon baking powder
• ¼ teaspoon salt
• ½ cup unsalted butter – softened to room temperature
• 1 cup granulated sugar
• 2 large eggs – at room temperature
• 1 teaspoon vanilla extract
• ½ cup milk – whole or 2%

How to Bake and Assemble

1. Preheat oven to 350°F (175°C) and generously grease a 9-inch round cake pan.
2. Trim the rhubarb ends and cut into ½-inch pieces; hull and halve the strawberries.
3. Melt 2 tablespoons unsalted butter.

4. In a medium bowl, toss the rhubarb, strawberries, ¾ cup granulated sugar, and melted butter; spread the mixture in an even layer across the bottom of the prepared pan.

   

5. Whisk together 1½ cups all-purpose flour, 1 teaspoon baking powder, and ¼ teaspoon salt.
6. Using a hand mixer, cream ½ cup softened unsalted butter with 1 cup granulated sugar until light and fluffy.
7. Add the eggs one at a time, mixing well after each addition, then stir in 1 teaspoon vanilla extract.

8. Alternate adding the flour mixture and ½ cup milk to the butter mixture, beginning and ending with the flour, mixing just until combined and scraping down the bowl as needed.

   

9. Gently pour the batter over the fruit in the pan and smooth the top with a spatula.
10. Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean and the edges begin to pull away from the pan (start checking at 35 minutes).
11. Remove the pan from the oven and let the cake cool in the pan for 10 minutes.

12. Place a plate over the pan and carefully invert to release the cake; gently nudge any fruit that sticks back onto the cake.

    

13. Allow the cake to cool on the plate a bit before slicing.

    

Pro Tips for Better Results

After baking this cake more times than I can count (and happily eating even more slices), I’ve picked up some handy tips that really make a difference:

• Fresh fruit is key – Use garden-fresh rhubarb and freshly picked strawberries whenever possible for the best flavor and texture.
• Grease your pan thoroughly – Make sure every corner and crevice is coated, especially if you’re using a Bundt pan. I swear by butter plus a light dusting of flour for the best release.
• Don’t overbake – Moist cake is the goal! Start checking at 35 minutes. When a toothpick comes out with just a few moist crumbs, it’s perfect.
• Flip at just the right time – That 10-minute cooling window is magic. Too soon, and the cake falls apart; too long, and it sticks.
• Store smart – Cover loosely with foil or a cake dome. Avoid plastic wrap directly over the fruit topping—it can make it soggy. Honestly, this cake tastes even better the next day.

Follow these tricks, and you’ll be serving up a dessert that everyone’ll rave about!

Serving Suggestions and Flavor Twists

This cake is delicious all on its own, but I love playing around with different ways to serve it. Here are some of my favorite ideas to dress it up:

• A scoop of vanilla ice cream melting over the warm fruit—pure bliss
• Fresh whipped cream with a touch of orange zest for a bright twist
• As a star at your afternoon tea, especially paired with a cup of Earl Grey
• For breakfast—because, hey, fruit makes it healthy, right?
• A dollop of Greek yogurt for a lighter, tangy contrast

No matter how you serve it, that first forkful of tender cake and sweet-tart fruit is always a delightful treat.

Storage and Make-Ahead Tips

This cake is best enjoyed the day it’s made, but if you have leftovers, no worries—they keep well for a few days when stored right. At room temperature, loosely cover the cake with foil or use a cake dome. Avoid plastic wrap touching the fruit topping to keep it from getting soggy. Properly stored, it stays fresh for up to 3 days.

• If refrigerating: Store single slices in an airtight container to keep them from drying out quickly. Refrigeration speeds up drying, so only do this if it’s warm or you need to keep it longer. Eat within 3 days.
• To freeze: Wrap individual slices in parchment or wax paper, then seal with foil or put into a freezer-safe bag. Freeze for up to a month. Thaw overnight in the fridge, then bring to room temperature for 30–60 minutes before serving.

• Reheating tips:

  • Microwave: Heat a slice for 20–30 seconds on medium power (adjust time depending on your microwave).
  • Oven: Warm at 300°F (150°C) for 8–12 minutes, tented with foil to keep the topping moist.
• From frozen: Thaw completely before reheating for best texture.

Make-ahead tip: You can prepare the fruit topping up to 24 hours ahead and keep it chilled. The fruit will release its juices, which actually makes the topping more flavorful. For the best texture and shine, bake the cake the same day you want to serve it or bake it one day ahead and store loosely covered at room temperature.

Answers to Common Questions

I get so many questions about this cake! Here are the answers to the most popular ones:

• Can I use frozen fruit? Definitely! Just thaw the rhubarb and strawberries completely and drain them very well—you can even pat them dry with paper towels. Because frozen fruit tends to release more liquid, you might need to bake a bit longer to get the cake set.
• How do I keep it from sticking to the pan? My go-to method is buttering every spot in the pan thoroughly, then lining the bottom with parchment paper. Also, don’t skip the 10-minute cooling window before flipping—the caramelized fruit needs time to set.
• Can this be made ahead? It’s best fresh, but honestly, I think it tastes even better the next day as flavors have time to meld. Store it loosely covered at room temperature for up to 3 days. Just avoid the fridge if you want to keep it moist.

See? This recipe is straightforward and forgiving. Now, grab your apron and bake with confidence!
