Ingredients of Rhubarb Cake
When it comes to whipping up a delicious rhubarb cake, having the right ingredients is essential. It’s like putting together a puzzle; each piece plays a part in creating the perfect flavor and texture. The combination of sweet and tart in this cake makes it a standout dessert for any occasion.
So, let’s explore what you’ll need to gather before you start baking!
Ingredients for Rhubarb Cake:
- 1/2 cup butter (softened)
- 1 1/2 cups sugar (white)
- 1 cup buttermilk
- 1 egg (beaten)
- 2 cups rhubarb (cut into small pieces)
- 2 cups flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1 cup brown sugar
- 1/4 cup butter (melted)
- 2 teaspoons cinnamon
Now that we’ve got our list, let’s talk a bit about those ingredients. For instance, using fresh rhubarb is key—it’s where that tart zing comes from, and trust me, you want the real deal.
If you can’t find fresh rhubarb, frozen works too, but make sure to thaw and drain it first to avoid a soggy cake.
And buttermilk? It’s like a secret weapon in baking; it adds moisture and a subtle tang that makes the cake extra fluffy.
If you don’t have buttermilk on hand, you can easily make your own by mixing regular milk with a tablespoon of vinegar or lemon juice. Just let it sit for a few minutes, and voilà! You’re ready to bake.
Now, let’s move on to the fun part—how to make this cake!
How to Make Rhubarb Cake

Alright, let’s plunge into the delicious world of making a Rhubarb Cake. First off, you’re going to want to grab your mixing bowl and start by creaming together 1/2 cup of softened butter and 1 1/2 cups of sugar. It’s like a little workout for your arms, but it’s worth it. You want this mixture to be nice and fluffy, almost like a cloud.
And while you’re at it, go ahead and add in that cup of buttermilk, 1 teaspoon of vanilla extract, and your beaten egg. Mix it all up until it’s well combined—trust me, the smell alone will have your mouth watering.
Now comes the fun part—let’s get that floury goodness in there. In a separate bowl, whisk together 2 cups of flour, 2 teaspoons of baking powder, and 1/2 teaspoon of salt. This is where the science of baking comes in; these ingredients are your foundation.
Once mixed, fold in those beautiful 2 cups of rhubarb, ensuring that every little piece is coated in flour. By doing this, you help prevent the rhubarb from sinking to the bottom of the cake, which would be a total tragedy. Gently fold this flour-rhubarb mixture into your egg mixture, and don’t be too rough; we want to keep that fluffiness intact.
When everything is nicely combined, pour the batter into a greased 8 x 8 pan. Now, let’s talk toppings because this is where the magic really happens. In a small bowl, blend together 1 cup of brown sugar, 1/4 cup of melted butter, and 2 teaspoons of cinnamon.
This mixture will add a lovely sweet crunch on top of your cake. Sprinkle it evenly over the batter—don’t hold back; this is the good stuff. Now, pop that pan into a preheated oven at 350 degrees Fahrenheit and bake for about 45 to 60 minutes. Keep an eye on it; you want the sides to pull away from the pan, and the center should be set.
And when you pull it out, just imagine the warm, sweet aroma filling your kitchen. But hold your horses, don’t plunge in just yet. This cake is best served hot, perhaps with a dollop of whipped cream or a scoop of vanilla ice cream, because who doesn’t love that?
Rhubarb Cake Substitutions & Variations
After you’ve mastered the basic Rhubarb Cake, you might be curious about how to switch things up.
I love experimenting with different fruits, so try substituting some of the rhubarb with strawberries or raspberries for a twist.
If you’re after a gluten-free option, use almond flour instead of regular flour.
For added richness, consider swapping the buttermilk with sour cream.
You can also play with spices—cinnamon and nutmeg together are divine!
And if you want a nutty flavor, toss in some chopped walnuts or pecans.
These variations keep my baking exciting and delicious! Give them a shot!
What to Serve with Rhubarb Cake
To enhance the delightful flavors of rhubarb cake, I often serve it with a dollop of whipped cream or a scoop of vanilla ice cream. The creaminess balances the tartness of the rhubarb beautifully.
I also love pairing it with a cup of hot tea or coffee, which complements the cake’s warmth. For a more festive touch, you could add fresh berries on the side, like strawberries or blueberries, to brighten the plate.
If you’re feeling adventurous, a drizzle of caramel sauce can take it to another level, adding a sweet contrast to the tangy rhubarb. Enjoy!
Additional Tips & Notes
While baking rhubarb cake, I’ve found a few tips that can make the process smoother and the results even better.
First, make certain your rhubarb is fresh and not too watery; it should be firm and vibrant.
I recommend measuring the flour accurately, using the spoon-and-level method to avoid a dense cake.
If you prefer a sweeter cake, feel free to add a bit more sugar.
To enhance flavor, try adding a pinch of nutmeg alongside the cinnamon.
Finally, let the cake cool slightly before serving—it’ll be easier to cut and will allow the flavors to meld beautifully.
Enjoy!
