Ingredients

Here’s what you’ll need to gather from your pantry and fridge. Simple, straightforward stuff!

  • 1/2 cup (1 stick) unsalted butter, softened: Make sure it’s truly soft, like you can easily indent it with your finger. This is key for creaming!
  • 1 cup granulated sugar: Just your standard white sugar to sweeten things up.
  • 2 large eggs: Room temperature is best for incorporating smoothly, but don’t stress too much if you forget – just pop them in warm water for a few minutes if you think of it!
  • 1/2 cup whole milk: Adds moisture and richness.
  • 1 1/2 cups all-purpose flour: The backbone of our cake.
  • 2 teaspoons baking powder: Our leavening agent, giving the cake a nice lift.
  • 1/2 teaspoon salt: Balances the sweetness and enhances all the flavors. Don’t skip it!
  • 2 cups rhubarb, chopped: The star! Chop it into about 1/2 to 1-inch pieces. No need to peel unless the stalks are very tough.
  • 2 tablespoons granulated sugar (for topping): For that irresistible crunchy topping.
  • 1 teaspoon ground cinnamon (for topping): Cinnamon and rhubarb are a match made in heaven!

How to Make It

Ready to make some magic? Follow these simple steps, and you’ll have a beautiful cake in no time.

  1. First things first, let’s get the oven ready! Preheat your oven to a cozy 350°F (175°C). Then, grab your 8×8 inch square pan or a 9-inch round baking pan. You’ll want to grease it really well (I like using baking spray or butter) and then lightly flour it. This step helps ensure your beautiful cake doesn’t stick! Tap out any excess flour.
  2. Now, in a large mixing bowl, it’s time to cream the softened butter and the first cup of granulated sugar. Beat them together with an electric mixer (or a whisk and some elbow grease!) until the mixture is light, fluffy, and pale yellow. This usually takes a few minutes.
  3. Next, add your eggs, one at a time, beating well after each addition. Scrape down the sides of the bowl to make sure everything is getting incorporated.
  4. In a separate, medium-sized bowl, whisk together your dry ingredients: the flour, baking powder, and salt. Just a quick whisk to distribute the baking powder and salt evenly.
  5. Time to combine the wet and dry! You’re going to alternately add the dry ingredients mixture and the milk to the butter/sugar/egg mixture. Start with about a third of the dry ingredients, mix gently until just combined, then add half of the milk, mix, then another third of the dry ingredients, mix, the rest of the milk, mix, and finally, the rest of the dry ingredients. The key here is to mix just until everything is incorporated. Don’t overmix! Overmixing can make the cake tough.
  6. Pour that lovely batter into your prepared baking pan and spread it out evenly with a spatula.
  7. Now for the best part – the rhubarb! Scatter the chopped rhubarb pieces evenly over the top of the batter. Don’t worry if some sink a little; that’s totally fine.
  8. In a small bowl, quickly stir together the two tablespoons of granulated sugar and the ground cinnamon. Sprinkle this sweet and spicy mixture evenly over all the rhubarb. This creates a delightful crust as the cake bakes.
  9. Pop the pan into your preheated oven. Bake for 40 to 50 minutes. You’ll know it’s done when the top is golden brown, the rhubarb is tender, and a toothpick inserted into the center of the cake comes out clean (maybe with a few moist crumbs attached, but no wet batter!).
  10. Once it’s baked to perfection, take the cake out of the oven and let it cool in the pan on a wire rack. Let it cool for a good while before you try to slice it – the flavors continue to meld and it holds its shape better.

Substitutions & Additions

This recipe is wonderfully versatile! Here are a few ideas to switch things up:

  • Frozen Rhubarb: Yes, you can use frozen rhubarb! Don’t thaw it first. Just toss the frozen pieces with a tablespoon or two of flour before scattering them over the batter. You might need to add a few extra minutes to the baking time.
  • Add Some Spice: A pinch of nutmeg or cardamom in the batter alongside the cinnamon topping would be lovely.
  • Other Fruits: Try swapping half the rhubarb for sliced strawberries, raspberries, or even blueberries for a different twist.
  • Nutty Crunch: Sprinkle some chopped almonds or walnuts over the cinnamon-sugar topping before baking.
  • Lemon Zest: Add the zest of one lemon to the batter for a bright, citrusy note that pairs beautifully with rhubarb.
  • Crumble Topping: Instead of the cinnamon sugar sprinkle, make a simple crumble topping (flour, sugar, butter cut together) and scatter that over the rhubarb before baking.

Tips for Success

Here are a few little pointers to help you make this cake perfectly every time:

  • Use Softened Butter: I can’t stress this enough! Cold butter won’t cream properly with the sugar, affecting the cake’s texture.
  • Don’t Overmix: Once you start adding the dry ingredients and milk, mix only until the flour streaks disappear. A few small lumps are okay! Overmixing develops the gluten and makes the cake tough.
  • Properly Grease and Flour: This simple step prevents sticking and is especially important with fruit cakes which can be a bit sticky.
  • Test for Doneness: Always use a toothpick inserted into the center of the cake to check if it’s fully baked.
  • Prep Ahead: While you shouldn’t make the batter ahead, you can chop the rhubarb the day before and keep it in the fridge in an airtight container.

How to Store It

If there’s any left, this cake stores beautifully!

Let the cake cool completely. Store it in an airtight container at room temperature for 2-3 days. For longer storage, you can keep it in the refrigerator for up to 5 days. It’s also lovely gently warmed up!

FAQs

Q: Do I need to peel the rhubarb?
A: Generally, no. Rhubarb stalks are only stringy if they are very thick and old. Young, tender stalks don’t need peeling. Just wash and chop!

Q: Can I use milk other than whole milk?
A: Yes, 2% or even skim milk will work, but whole milk provides the richest texture. You could also use a non-dairy milk like almond or oat milk.

Q: My rhubarb is really tart, will the cake be sour?
A: The amount of sugar in the batter and the topping is designed to balance the rhubarb’s tartness. As it bakes, the rhubarb softens and its tartness complements the sweet cake beautifully.

Q: What’s the best way to serve this cake?
A: It’s fantastic on its own, but a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of simple glaze takes it over the top!
