Ingredients

For the rhubarb layer:

200 grams chopped fresh rhubarb (2–3 stalks)
1½ tbsp granulated sugar

For the cake batter:

2 large eggs, room temperature
200 grams (1 cup) granulated sugar
250 grams (~2 cups) all-purpose flour
1 tsp baking powder
½ tsp salt
1½ tsp vanilla extract
120 ml (½ cup) vegetable oil
120 ml (½ cup) milk

Optional topping:

Demerara sugar

Notes & Substitutions: Room-temperature eggs are important here — they help the batter come together smoothly and give the cake better lift. You can swap vegetable oil for any neutral oil like sunflower or canola. Whole milk gives the best texture, but 2% works fine. If you don’t have demerara sugar, raw sugar or turbinado sugar will give a similar crunch. Frozen rhubarb can be used in a pinch — just thaw and pat it dry before using.

Instructions

Preheat your oven to 350°F (175°C). This gives the oven time to fully heat up so your cake rises evenly from the moment it goes in.
Prepare your baking tin. Lightly butter or oil a 9-inch round baking tin, then cut a circle of parchment paper to line the bottom. This prevents sticking and makes removing the cake much easier.
Macerate the rhubarb. Toss the chopped fresh rhubarb with 1½ tbsp of granulated sugar in a small bowl. Let it sit while you make the batter — the sugar draws out moisture and softens the rhubarb slightly, which means more flavor in every bite.
Beat eggs and sugar. In a stand mixer fitted with a whisk attachment, or using an electric hand mixer, beat the 2 large eggs and 200 grams of granulated sugar together until the mixture is pale, light, and has doubled or tripled in volume. This takes about 3–5 minutes and is key to a fluffy texture.
Combine dry ingredients. In a separate bowl, whisk together the flour, baking powder, and salt. Set aside.
Mix wet ingredients. In a liquid measuring cup, stir together the vanilla extract, milk, and vegetable oil. Using a measuring cup makes it easy to pour in a steady stream.
Alternate adding wet and dry. With the mixer on low, add half the dry ingredients to the egg mixture, then half the wet ingredients. Repeat with the remaining halves. Fold gently with a rubber spatula to finish — this keeps the batter light and avoids overdeveloping the gluten.
Fold in the rhubarb. Add most of the sugared rhubarb to the batter, keeping a small handful aside for the top. Fold gently just until distributed — don’t overmix or you’ll lose that tender crumb.
Fill the tin. Pour the batter into your prepared tin and spread it evenly.
Top and bake. Scatter the reserved rhubarb over the top, then sprinkle with demerara sugar if using. Bake for 40–45 minutes, or until a cake tester or toothpick inserted into the center comes out clean. Baking time may vary slightly depending on your oven and tin.
Cool and serve. Let the cake rest in the tin for 5 minutes, then turn it out onto a wire rack to cool completely. Slice and enjoy!

Pro Tips & Troubleshooting

Most common mistake: Skipping the egg-and-sugar beating step. This is what gives the cake its lift and soft texture — don’t rush it. Beat until truly pale and fluffy.

Technique tip: When alternating wet and dry ingredients, always start and end with the dry ingredients. It helps the batter stay stable and prevents it from becoming too dense.

Troubleshooting: If your cake sinks in the middle after baking, it’s likely underbaked. Every oven runs differently, so trust the toothpick test over the timer — it should come out completely clean with no wet batter clinging to it.

Serving, Storage & Variations

Serving: This rhubarb cake is lovely on its own, but a dollop of lightly whipped cream or a scoop of vanilla ice cream takes it to the next level. It also pairs beautifully with a hot cup of tea or coffee.

Storage: Store the cooled cake in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. To reheat, warm individual slices in the microwave for 20–30 seconds.

Variations:

Rhubarb & Strawberry Cake: Replace half the rhubarb with chopped fresh strawberries for a classic flavor pairing.
Spiced Rhubarb Cake: Add ½ tsp of ground cinnamon and a pinch of nutmeg to the dry ingredients for a warm, cozy twist.
Lemon Rhubarb Cake: Stir in the zest of one lemon with the wet ingredients for a bright, citrusy note.

Frequently Asked Questions

Can I use frozen rhubarb instead of fresh?

Yes, frozen rhubarb works well in this recipe. Just make sure to thaw it completely and pat it dry with paper towels before using, so excess moisture doesn’t affect the batter.

Do I need to peel the rhubarb before chopping?

No peeling necessary! Simply wash the stalks, trim the ends, and chop them into roughly 1-inch pieces. The skin softens during baking and you won’t notice it in the finished cake.

Can I make this rhubarb cake ahead of time?

Absolutely — this cake actually gets a little more moist the day after baking. Bake it the night before, let it cool fully, and store it in an airtight container until ready to serve.
