Why Rhubarb and Summer are a Match Made in Heaven

Rhubarb season peaks in the warmer months, making it a quintessential summer ingredient. Its tartness pairs perfectly with summer desserts like pies, cobblers, and, of course, cakes. But beyond taste, rhubarb brings plenty to the (picnic) table. It’s rich in fiber, which aids digestion, and its antioxidants work to combat inflammation.

This easy rhubarb cake recipe highlights everything we love about this vibrant vegetable (yes, it’s technically a veggie!) while keeping things light and effortlessly satisfying.

What Makes This Rhubarb Cake Stand Out?

Sweet Meets Tart: The cake itself is subtly sweet, letting the natural tang of the rhubarb shine through.
Quick and Simple: With just 20 minutes of prep, this recipe is beginner-friendly and stress-free, even for those new to baking.
Healthy Twist: Rhubarb is not only delicious but also nutrient-packed, making this cake a treat you can enjoy guilt-free.
Versatile Snack: Serve it as an afternoon pick-me-up, a light dessert, or even at breakfast with your morning coffee.

Ingredients for Your Easy Rhubarb Cake

You don’t need anything fancy to bring this recipe to life. Here’s what you’ll need from your pantry and fridge:

1 1/2 cups all-purpose flour
1 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1 tsp cinnamon (I love to add this, but you can also leave it out)
3/4 cup granulated sugar
1/3 cup coconut oil
1 large egg
1 tsp vanilla extract
1 cup buttermilk
2 cups chopped rhubarb

If you’ve never baked with rhubarb before, don’t be intimidated. Simply trim the ends, remove any stringy parts, and chop it into small pieces (about the size of a blueberry).

Step-by-Step Guide to Making the Perfect Rhubarb Cake

Here’s how to whip up this moist, flavorful cake in just a few easy steps.

1. Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan. This ensures the cake doesn’t stick and slides out perfectly after baking.

2. Prepare the Dry Ingredients

In a large bowl, whisk together the flour, baking powder, baking soda, and salt. This step helps ensure even distribution of all dry ingredients, preventing uneven pockets in the batter.

3. Mix the Wet Ingredients

In a separate bowl, combine the sugar, oil, egg, and vanilla extract. Beat until the mixture is smooth and well-combined. This will serve as the foundation for your cake’s flavor.

4. Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Start and end with the dry ingredients, as this helps the batter stay light and airy. Overmixing can lead to a dense cake, so stir until just combined.

5. Fold in the Rhubarb

Gently incorporate the chopped rhubarb into the batter. Folding prevents the rhubarb from sinking to the bottom while maintaining the batter’s fluffiness.

6. Time to Bake

Pour the batter into the prepared baking pan, spreading it evenly. Place the cake in the oven and bake for 25–30 minutes. To check if it’s done, insert a wooden skewer or toothpick into the center of the cake. If it comes out clean, your cake is ready!

7. Cool and Serve

Allow the cake to cool completely in the pan before slicing. This ensures clean cuts and avoids crumbling. Once cooled, it’s ready to enjoy!
