Ingredients for apple and rhubarb cake
Tart rhubarb, sweet apples, and buttery streusel—here's what brings this showstopper cake to life.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Rhubarb Stalks 🍓 | 2 ½ lbs | Fresh, trimmed and chopped |
| Apples 🍎 | 4 medium | Honeycrisp or Granny Smith, peeled and diced |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 💧 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Ground Cinnamon 🌿 | 1 ½ tsp | For cake and streusel |
| Old-Fashioned Oats 🌾 | ½ cup | Blended into flour for streusel |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The rhubarb is non-negotiable—fresh stalks only (no substitutes). Look for vibrant red stalks with crisp texture at Whole Foods or your local farmers' market. Apples should be firm and tart—Honeycrisp or Granny Smith work best. For the flour, King Arthur brand is my go-to for consistent results. The butter? Plugrá brand stays cold longer when making the streusel. If you can't find fresh rhubarb, frozen works in a pinch—just thaw and drain well before using.
No vanilla extract? 1 tsp vanilla sugar works surprisingly well. Short on oats? Crushed graham crackers add texture without changing flavor. The baking powder must be fresh—if it's more than 6 months old, replace it. For a gluten-free version, swap the flour for a 1:1 baking blend. The lemon juice brightens everything—don't skip it. If you're using pre-peeled apples, rinse them well to remove any wax coating. The streusel ratio is key: too much butter makes it greasy, so measure carefully.
The rhubarb can be prepped ahead—steam for 5 minutes and store covered in the fridge for up to 2 days. Diced apples oxidize fast, so toss them with the lemon juice immediately. The cake keeps well wrapped at room temperature for 3 days or in the fridge for 1 week. For longer storage, freeze slices wrapped individually—they reheat beautifully in the oven. The streusel topping stays crisp for 2 days if stored in an airtight container.
Why You'll Love This Recipe
- Here’s what sold me: it doesn’t dry out. I’ve had this cake last five days in the fridge, and the texture stays tender. Plus, the rhubarb’s natural pectin keeps the layers from getting gummy. Leftovers? More like always leftovers.
- No-Fuss Layers: I swear by this recipe because it’s basically a cake in a bowl—just mix the dry ingredients, fold in the butter and sugar, then gently stir in the chopped rhubarb and apples. No fancy techniques, no waiting for dough to rise, and the layers stay moist for days.
- Tart-Sweet Magic: That rhubarb? It’s the star—bright, tangy, and just sweet enough when paired with the brown sugar and apples. The butter makes every bite rich, but the acidity keeps it from being heavy. Honestly, it’s the kind of flavor that makes you reach for a second slice without thinking.
- Weekend or Weeknight: Between us, this cake works for everything. Bake it for a lazy Sunday brunch, slice it for a quick office dessert, or even pack it in lunchboxes. (Yes, even on a Tuesday night.) The rhubarb’s peak season means it’s budget-friendly too—no need for expensive fruit.
Step-by-step instructions for apple and rhubarb cake
This method delivers a perfectly balanced tart-sweet cake with a crunchy streusel topping every time.
Prepare the Fruit Filling
In a large bowl, combine the 2.5 lbs rhubarb stalks and 4 medium apples, both chopped into ½-inch pieces. The rhubarb should be trimmed of any leafy stems and cut into even chunks. Add 1 tablespoon lemon juice and toss gently to prevent browning while preserving the bright acidity that balances the apples' sweetness.
Let the mixture sit for 10 minutes while you prepare the cake batter. This brief rest allows the lemon juice to penetrate the fruit, enhancing the flavor profile. I find this step crucial for preventing a mushy texture later—it's all about timing and acidity control.
Make the Cake Batter
In a separate large bowl, whisk together the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 0.5 cup light brown sugar, 2 teaspoons baking powder, and 0.5 teaspoon salt. Sift the flour mixture once to ensure a light, airy texture—this prevents dense cake layers. In another bowl, beat the 2 whole large eggs until just combined, then mix in 1 tablespoon vanilla extract. Combine the wet and dry ingredients gently, just until no flour streaks remain.
Fold in the reserved rhubarb-apple mixture, being careful not to overmix. The batter should be thick but pourable. I like to use a rubber spatula for this step—it helps maintain the fruit's integrity while distributing it evenly throughout the batter. The final texture should resemble a well-stirred cake batter with visible fruit pieces.
Prepare the Streusel Topping
In a medium bowl, cut the 1 cup unsalted butter into small cubes and let it sit at room temperature for 10 minutes to soften slightly. Mix with 0.5 cup old-fashioned oats, 1.5 teaspoons ground cinnamon, and the remaining 0.5 cup light brown sugar (if you didn't use it all in the cake batter). Pulse the oats in a food processor until they resemble fine crumbs, or grind them by hand using a rolling pin—this creates a more uniform texture.
Work the mixture quickly with your fingers until it forms coarse crumbs. The streusel should hold together when pressed but still have visible flecks of oat and butter. Don't overwork it—just enough to combine. This topping is what gives the cake its signature crunch, so take your time to get it right.
Assemble and Bake the Cake
Preheat your oven to 350°F and grease a 9x13-inch baking dish thoroughly. Spread half of the cake batter evenly in the prepared pan, then add all of the remaining rhubarb-apple mixture, distributing it in an even layer. Top with the remaining cake batter, creating a marbled effect by gently swirling with a knife.
Sprinkle the streusel topping evenly over the entire surface, pressing down lightly to ensure good contact with the cake batter. Bake for 45-50 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should pull away slightly from the pan, indicating proper doneness. If the streusel browns too quickly, tent the cake with foil after 30 minutes to prevent over-browning.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Transfer to a wire rack to cool completely before slicing. This gradual cooling process prevents the cake from becoming gummy in the center. The contrast between the warm, slightly sticky cake and the cool, crunchy streusel is what makes this dessert truly special.
Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream. The tartness of the rhubarb and the sweetness of the apples create a perfect balance, while the cinnamon streusel adds a delightful textural contrast. Each slice should reveal layers of moist cake, juicy fruit, and buttery crunch—proof that careful layering pays off.
Pro Tips For Making Apple And Rhubarb Cake
- Preheat Pan with Cake: The oven’s hot, but the pan’s cold—don’t skip this. Place your cake pan in the oven for 5 minutes while preheating to 350°F (175°C). I learned this the hard way when my edges turned doughy because the pan absorbed heat too slowly.
- Trim Rhubarb Like a Pro: Skip the thick core—it’s tough and won’t soften. Cut stalks into ½-inch chunks, then slice off the fibrous ends with a sharp knife. My grandmother swore by this, and she was right: the texture makes all the difference.
- Don’t Overmix the Batter: Two minutes max with a mixer, or until just combined. Overworking the flour develops gluten, and suddenly you’ve got a dense brick instead of a tender crumb. I was skeptical until I tried it—now I stop as soon as the dry bits disappear.
- Press Apples into the Batter: Chop them into small pieces and fold them in gently, but don’t skip pressing them down into the batter before baking. This ensures even distribution and prevents a watery center. Sounds weird, but it works—your future self will thank you.
Wine and beer pairings for this apple and rhubarb cake
White Wine Pairings
A crisp Sauvignon Blanc from New Zealand or Loire Valley is my go-to choice for this cake—its bright acidity mirrors the rhubarb's tartness while the citrus notes complement the apples' sweetness. Look for a bottle with 12-13% ABV like Kim Crawford Sauvignon Blanc or Oyster Bay Sauvignon Blanc. The wine's herbal undertones enhance the cinnamon in the streusel, creating a harmonious balance that cleanses your palate between bites. 🍷
Red Wine Options
For those who prefer red, a light-bodied Pinot Noir from Oregon or Burgundy works beautifully—its delicate fruit profile and subtle earthiness won't overpower the cake's flavors. I recommend La Crema Pinot Noir or Domaine Drouhin Oregon Pinot Noir. The wine's acidity helps cut through the cake's richness, while its red fruit notes echo the apples' natural sweetness. Serve slightly chilled (50-55°F) for the best experience.
Beer Pairings
A Belgian witbier like Hoegaarden or Stella Artois is a fantastic beer pairing—its coriander and citrus notes contrast perfectly with the cake's spiced sweetness. The effervescence also helps balance the cake's density. For a more robust option, try a honey ale like Allagash Honey Farmer, which complements the apples' natural sweetness while the honey notes enhance the streusel's caramelized flavor. Keep the beer well-chilled (40-45°F) to maintain its crispness. 🍺
Cider Complements
Don't overlook dry hard cider as a pairing—brands like Angry Orchard Dry or Strongbow add a refreshing contrast to the cake's richness. The cider's slight tartness enhances the rhubarb's acidity, while its subtle apple notes create a delightful echo of the cake's filling. Serve it ice-cold (38-40°F) to highlight its crisp, clean finish. For a festive touch, garnish with a cinnamon stick to tie into the cake's spiced streusel.
After-Dinner Digestif
Finish your dessert experience with a small glass of Port wine—a Ruby Port like Graham's Six Grapes or a Tawny Port such as Taylor's 10-Year-Old pairs exceptionally well. The Port's sweetness and caramel notes complement the cake's buttery streusel, while its alcohol content helps cleanse the palate. Serve at room temperature (60-65°F) to appreciate its full complexity. A single sip is all you need to complete this dessert pairing perfectly. 💫

Frequently asked questions
Can I substitute rhubarb with another fruit?
While rhubarb's tartness is key, you can swap it for 1.5 cups of diced tart cherries (fresh or frozen) or 1 cup of cranberry sauce for a similar tangy contrast. For a milder flavor, peaches or pears work but reduce the sugar in the cake batter by 0.25 cup to balance sweetness.
Why does my cake turn out dense?
Overmixing the batter or using cold butter in the streusel are common culprits. Sift the flour first and fold the fruit gently—just until combined. For the streusel, use cold butter and work quickly to avoid melting. Also, ensure your baking powder is fresh and the oven is fully preheated to 350°F.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking blend (like Bob's Red Mill) and add 1 teaspoon xanthan gum to improve texture. Use the same measurements for other ingredients. For the streusel, ensure your oats are certified gluten-free. The cake may be slightly denser but still delicious!
Can I bake this in a different pan size?
Yes, but adjust baking time. For a 9-inch round pan, bake 40-45 minutes*; for an 8x8-inch pan, reduce to 35-40 minutes. Always check doneness with a toothpick. Line the pan with parchment paper for easy removal, and reduce streusel by 25% if using a smaller pan to avoid overcrowding.
What’s the best way to store leftovers?
Wrap tightly in plastic wrap or foil and store at room temperature for 3 days, or refrigerate for 1 week. For longer storage, freeze slices in an airtight container for up to 3 months. Reheat individual slices in the oven at 300°F for 5-10 minutes** to restore the streusel’s crunch.
