What Is Raspberry Lemon Crumb Cake? 🍰
A crumb cake is a soft cake topped with a generous layer of buttery streusel before baking. As the cake rises in the oven, the crumble becomes golden and crisp, creating an irresistible contrast in texture.
In this version, fresh lemon adds brightness while raspberries provide juicy bursts of sweetness and tartness throughout the cake. Every slice has tender cake, pockets of fruit, and a crunchy buttery topping.
Unlike heavily frosted cakes, crumb cakes feel light and casual while still looking impressive enough to serve to guests.
They’re perfect for almost any occasion because they can be enjoyed warm, chilled, or at room temperature.
Why Raspberry and Lemon Are the Perfect Pair 🍋❤️
Few flavor combinations are as timeless as raspberry and lemon.
The sweetness of ripe raspberries balances the fresh citrus notes from the lemon, creating a dessert that tastes vibrant rather than overly rich.
The lemon also enhances the berries, making their natural flavor even brighter during baking.
Together they create a cake that’s refreshing, fruity, and perfect throughout spring and summer, although it’s just as delicious during the colder months with frozen raspberries.

The Secret to a Moist Crumb Cake ✨
One of the biggest concerns beginner bakers have is ending up with a dry cake.
Fortunately, this recipe is designed to stay incredibly moist.
Using sour cream or Greek yogurt adds richness while helping the cake remain soft for several days. Fresh lemon juice adds moisture without making the batter too thin, while the raspberries release their juices during baking, creating little pockets of fruity goodness throughout each slice.
The buttery crumble topping also helps protect the cake underneath, keeping it wonderfully tender.
Tips for Baking the Best Raspberry Lemon Crumb Cake 👩🍳
A few simple tips can make a big difference.
Use fresh lemon whenever possible
Fresh lemon zest provides much more flavor than bottled lemon juice alone. The zest contains fragrant oils that give the cake its bright citrus aroma.
Don’t overmix the batter
Once the flour is added, mix only until no dry streaks remain. Overmixing develops gluten, which can make cakes dense instead of light and tender.
Fold the raspberries in gently
Raspberries are delicate and can break apart easily. Fold them into the batter carefully to help them stay whole.
Keep the crumble chunky
When making the crumble topping, stop mixing once large crumbs form. Bigger crumbs create a more satisfying texture after baking.
Check for doneness carefully
Every oven is slightly different. Insert a toothpick into the center of the cake, avoiding large raspberries. It should come out with a few moist crumbs but no wet batter.
Fresh vs Frozen Raspberries 🫐
One of the best things about this recipe is its flexibility.
Fresh raspberries work beautifully when they’re in season, providing bright flavor and beautiful color.
Frozen raspberries are an excellent option during the rest of the year. They allow you to enjoy this cake anytime without sacrificing much flavor.
If using frozen berries, there’s no need to thaw them first. Adding them directly from the freezer helps prevent excess juice from coloring the batter.
When to Serve Raspberry Lemon Crumb Cake 🎉
This versatile cake fits almost any occasion.
It’s perfect for:
- Weekend brunch
- Mother’s Day
- Easter celebrations
- Baby showers
- Bridal showers
- Afternoon tea
- Summer picnics
- Coffee mornings
- Potluck gatherings
- Everyday baking
Because it isn’t overly rich, guests often come back for a second slice.
Troubleshooting and Common Mistakes 🚨
Even beginner-friendly cakes can have a few challenges. Here’s how to avoid the most common ones.
My cake turned out dry
Dry cake is usually caused by overbaking or measuring too much flour. Measure carefully and remove the cake from the oven as soon as it’s baked through.
My raspberries sank
Tossing the raspberries lightly in flour before folding them into the batter can help suspend them more evenly throughout the cake.
My crumble topping melted
If the butter becomes too warm while making the crumble, the topping may spread instead of staying crumbly. Chill it for a few minutes before sprinkling it over the batter.
My crumble disappeared into the cake
Large crumbs work best. If the topping is too fine, it can absorb into the batter as it bakes.
My cake is gummy around the berries
Raspberries naturally release moisture while baking. Make sure the cake is fully baked before removing it from the oven, even if the fruit still looks juicy.
My cake stuck to the pan
Grease and line your baking pan with parchment paper whenever possible. Allow the cake to cool slightly before removing it from the pan.
Storage Tips ❄️
This cake stores beautifully, making it ideal for baking ahead.
- Store in an airtight container at room temperature for up to 2 days.
- Refrigerate for up to 5 days for maximum freshness.
- Bring to room temperature before serving for the softest texture.
- Freeze individual slices for up to 3 months.
The crumble stays surprisingly crisp, while the cake remains moist thanks to the fruit.
Delicious Variations 🍓
Once you’ve mastered the classic recipe, it’s easy to customize.
Try swapping the raspberries for:
- Blueberries
- Blackberries
- Strawberries
- Mixed berries
You can also add sliced almonds to the crumble topping for extra crunch or drizzle the cooled cake with a simple lemon glaze for an extra burst of citrus flavor.
These small changes make the recipe easy to enjoy throughout the year with whatever fruit is in season.
Why This Recipe Works 💡
Every element of this cake has a purpose.
The sour cream creates a soft, moist crumb. The fresh lemon brightens the entire cake without overpowering it. Juicy raspberries add natural sweetness and tartness, while the buttery crumble topping provides texture and richness.
Together, they create a bakery-style cake that’s comforting, beautiful, and full of fresh flavor.
It’s a recipe that’s simple enough for beginners but impressive enough to share at any gathering.

- 2 (2) Large Eggs
- 2 tbsp (2 tbsp) Lemon Juice
- 150 g (¾ cup) Plain Yogurt
- 200 g (1 ½ cups) All Purpose Flour
- 1 ½ tsp (1 ½ tsp) Baking Powder
- ½ tsp (½ tsp) Baking Soda

For the Glaze

- 250 g (2 cups) Powdered Sugar
- 3 tbsp (3 tbsp) Milk
- 1 tbsp (1 tbsp) Lemon Juice
Instructions
- Preheat the oven to 350℉/170℃. Line an 8×8" square pan.
Make the Crumb Topping
- Add the white sugar, brown sugar, flour and melted (cooled) butter in a bowl. Mix to combine. Set aside.
Make the Cake Batter
- In a small bowl, add the lemon zest to the white sugar and rub with your fingers to create 'lemon sugar'. Add this to a large bowl/the bowl of a stand mixer (paddle attachment).
- Add the butter and whisk on high to cream together (should look pale and fluffy). Add the eggs, yogurt and lemon juice and whisk again.
- Add the flour, baking powder and baking soda and fold together (or use the paddle attachment on a very low speed until just combined). Finally, fold in the milk. The batter should be thick but spreadable.
- Pour half the batter into the prepared pan and spread in an even layer. Scatter over the raspberries, then the 2 tbsp sugar.
- Add the remaining half of the batter and again, spread to form an even layer.
- Top with the crumb topping, scatter this over the cake batter. Bake for 35-40 minutes, until a skewer inserted comes out clean. Let cool.
For the Glaze
- Once the cake is cool, place the raspberries (defrosted or use fresh) in a bowl. Mash with a fork. Add the powdered sugar, milk and lemon juice and mix to form a glaze. Add more milk/powdered sugar to reach your desired consistency. Pour this glaze over the cake, slice and serve!
