Ingredients
- 1 cup diced strawberries
- 1 cup diced rhubarb
- 2 cups all-purpose flour
- 4 tablespoons all-purpose flour (divided)
- 2 teaspoons baking powder
- ½ teaspoon salt
- 1 egg (room temperature)
- ¾ cup granulated sugar
- ¼ cup unsalted butter (softened)
- 3 tablespoons unsalted butter (softened)
- ½ cup milk
- ¾ cup brown sugar
- ¾ cup powdered sugar
- 1 tablespoon milk (for glaze)
- ½ teaspoon vanilla extract
Step-by-Step Instructions
Preparing the Ingredients
Preheat your oven to 350°F and grease an 8×8-inch baking pan. Then, toss the diced strawberries and rhubarb with one tablespoon of flour to coat them evenly, which helps keep them suspended in the batter. Meanwhile, whisk together the remaining flour, baking powder, and salt in a separate bowl until smooth and lump-free.
Cooking Instructions
In a large bowl, beat the sugar, butter, and egg until creamy, then mix in the milk until smooth. Next, add the dry ingredients and stir just until combined before gently folding in the coated fruit. Spread the batter evenly in the pan. In another bowl, mix brown sugar, butter, and flour until crumbly, then sprinkle it over the batter. Bake for 35 to 40 minutes until a tester comes out with a few crumbs. Let the cake cool slightly, then whisk glaze ingredients and drizzle over the top.
Tips for Perfect Results
Common Mistakes to Avoid
Avoid overmixing the batter because it can make the cake dense instead of tender. Also, do not skip coating the fruit with flour, since that step keeps the strawberries and rhubarb evenly distributed. Finally, watch the baking time closely to prevent drying out the cake.
Pro Tips for Better Flavor
Use fresh, ripe strawberries for the best sweetness, and balance them with firm rhubarb for that classic tang. Let the cake cool before adding glaze so it sets beautifully. For even richer flavor, serve the cake slightly warm with a light dusting of extra powdered sugar.
Serving and Storage
How to Serve
Serve Spaceships Strawberry Rhubarb Cake slightly warm or fully cooled, depending on your preference. It pairs wonderfully with coffee, tea, or even a scoop of vanilla ice cream for a more indulgent treat.

How to Store Leftovers
Store leftover cake in an airtight container at room temperature for up to two days, or refrigerate it for up to five days. When ready to enjoy again, warm individual slices briefly to bring back their soft texture.
Conclusion
Spaceships Strawberry Rhubarb Cake offers a fantastic combination of sweet and tart flavors in a soft, moist crumb. With simple steps and reliable results, it makes a great choice for both everyday baking and special occasions. Try it once, and it may quickly become one of your favorite go-to desserts.
