Ingredients You’ll Need
These ingredients are straightforward but essential, each playing a vital role from flavoring and texture to the perfect crumb and zest that make this cake unforgettable.
- All-purpose flour: The backbone of the cake and crumb topping, giving structure and tenderness.
- Granulated sugar: Adds sweetness and helps with browning in both cake and crumb.
- Lemon zest: Bursts of fresh citrus flavor that wake up every bite.
- Salt: Enhances all other flavors and balances the sweetness.
- Butter: Cold for the crumb topping to create that sandy texture; softened for the cake to produce a creamy batter.
- Baking soda: Provides gentle lift and helps the cake rise beautifully.
- Eggs (separated): Egg yolks enrich the batter; whipped egg whites make the cake light and airy.
- Vanilla and lemon extracts: Double the fragrance and depth of lemon flavor.
- Plain Greek yogurt: Adds moisture and a slight tang that complements the lemon without overpowering.
- Sugar for meringue: Creates stiff peaks that lighten the cake texture amazingly.

How to Make Lemon Crumb Cake with Lemon Curd and Streusel Topping Recipe
Step 1: Prepare Lemon Curd
If you’re up for making it from scratch, start early since lemon curd needs a few hours chilling. Beat softened butter and sugar until creamy, then mix in eggs one at a time and the vibrant lemon zest. Slowly pour in fresh lemon juice while mixing, and microwave in intervals to thicken the curd. Cover it tightly with plastic wrap on its surface and refrigerate to develop that rich, custardy texture perfect for swirling into the cake batter.
Step 2: Preheat and Prep
Set your oven to 350 degrees Fahrenheit and prepare a 9×9 inch baking dish by spraying it with nonstick spray. This upfront step ensures your luscious cake won’t stick and will bake evenly.
Step 3: Make the Streusel Crumb
Combine flour, sugar, lemon zest, and a pinch of salt, then cut in cold butter with your fingers until the mixture resembles coarse sand. This crumbly topping bakes into a crisp, buttery layer that adds irresistible texture and a little burst of lemon aroma on top of your cake.
Step 4: Prepare the Cake Batter
Mix flour, baking soda, and salt in one bowl. In your mixer, beat softened butter and sugar on high speed until creamy for several minutes. Add egg yolks one at a time, then vanilla and lemon extracts and fresh lemon zest to amp up citrus flavor. Alternate adding the flour mixture and Greek yogurt, starting and ending with the dry ingredients, to keep the batter tender and moist.
Step 5: Fold in Egg Whites
Beat egg whites with sugar until stiff peaks form — this aerated meringue is what makes the cake texture delightfully light. Gently fold into the batter without deflating those peaks, ensuring a fluffy finish.
Step 6: Assemble and Bake
Spread the batter evenly in your prepared pan. Dollop spoonfuls of chilled lemon curd over the top, then gently swirl it with a knife through the batter to create beautiful lemon ribbons. Sprinkle the streusel crumb generously over everything, then bake for 40 to 45 minutes until a tester comes out clean. Once cooled slightly, dust with powdered sugar for a lovely finish.
How to Serve Lemon Crumb Cake with Lemon Curd and Streusel Topping Recipe
Garnishes
Since the cake itself is bursting with lemon flavor and texture, simple garnishes work best. A few thin lemon slices, a sprinkle of powdered sugar, or some fresh mint leaves add a touch of elegance without overshadowing that incredible lemon curd and streusel topping.
Side Dishes
This cake pairs wonderfully with light beverages like chamomile tea, sparkling water with a splash of lemon, or a creamy vanilla ice cream to contrast the tangy citrus notes. Fresh berries on the side also work beautifully when you want a fresh, fruity companion.
Creative Ways to Present
For a party, serve the cake in petite squares on decorative plates with a dollop of whipped cream and a drizzle of extra lemon curd. You can also layer slices between sweet cream cheese frosting to punch up the decadence or place individual slices on dessert stands for an inviting display.
Make Ahead and Storage
Storing Leftovers
Wrap leftover cake tightly with plastic wrap or store in an airtight container, keeping it refrigerated to maintain freshness. It will stay moist and delicious for up to 3 days, ideal for enjoying multiple servings without drying out.
Freezing
If you want to enjoy this cake later, freeze it either as assembled slices or whole. Wrap pieces in plastic wrap and aluminum foil and store in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge to retain the perfect texture and flavor.
Reheating
Reheat chilled slices in a microwave for 15 to 20 seconds or warm gently in the oven at low heat to bring back that fresh-baked feel. Avoid overheating to preserve the delicate crumb and luscious lemon curd within.
FAQs
Can I use store-bought lemon curd for this cake?
Absolutely! While homemade lemon curd adds a fresh tang and creamy richness, using high-quality store-bought lemon curd is a convenient and delicious option that still makes this cake shine.
What if I don’t have Greek yogurt? Can I substitute?
You can substitute plain yogurt or sour cream for Greek yogurt in equal amounts. These alternatives maintain moisture and tanginess, although they might slightly alter the cake’s texture.
Is it possible to make this cake dairy-free?
Yes, you can use dairy-free butter and yogurt substitutes to make this cake suitable for dairy allergies. Keep in mind that the flavor may vary slightly, but the core lemony goodness will remain.
How do I know when the cake is fully baked?
Insert a toothpick or cake tester into the center of the cake. If it comes out clean or with just a few moist crumbs, your cake is perfectly baked and ready to come out of the oven.
Can I use lemon juice instead of lemon zest?
Lemon zest offers a bright, concentrated lemon flavor that juice alone can’t replicate. Using both maximizes freshness, but if you don’t have zest, increase the lemon juice slightly and consider adding a bit of lemon extract for extra punch.

Instructions
- Prepare Lemon Curd (Optional): Begin by making the lemon curd if you do not have store-bought. Beat butter and sugar in an electric mixer until creamy. Add eggs one at a time, mixing well after each. Mix in lemon zest, then gradually stream in lemon juice with the mixer on medium-low speed. The mixture may appear curdled.
- Cook Lemon Curd: Transfer mixture to a microwave-safe bowl and microwave for 5 minutes, stirring every minute. Continue microwaving in 30-second increments until mixture thickly coats the back of a spoon. Press plastic wrap directly onto curd and chill in fridge for 2 to 4 hours until thickened.
- Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Spray a 9×9 inch baking dish with nonstick spray or grease well.
- Make Crumb Topping: In a bowl, whisk together flour, sugar, lemon zest, and salt. Add cold butter pieces. Using your fingers, rub the butter into the dry ingredients for several minutes until the texture resembles coarse sand.
- Mix Dry Ingredients for Cake: In a separate bowl, combine flour, baking soda, and salt.
- Cream Butter and Sugar: Using an electric mixer, beat softened butter and sugar on high speed until creamy and fluffy, about 3 to 4 minutes.
- Add Egg Yolks and Flavorings: Beat in egg yolks one at a time, then add vanilla extract, lemon extract, and lemon zest, mixing until blended.
- Incorporate Dry Ingredients and Yogurt: Beat in half of the flour mixture just until combined, then add Greek yogurt. Mix in remaining flour mixture until just incorporated.
- Whip Egg Whites: In a clean bowl, whip egg whites with an electric hand mixer until foamy. Gradually add 2 tablespoons sugar and continue beating until stiff peaks form.
- Fold Egg Whites into Batter: Gently fold the beaten egg whites into the cake batter to keep it light and airy.
- Assemble Cake: Spread the batter evenly into the prepared baking dish. Dollop lemon curd over the batter and gently swirl it in with a knife for a marbled effect.
- Add Crumb Topping and Bake: Sprinkle the prepared crumb mixture evenly over the top. Bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean.
- Finish and Serve: Remove from the oven and allow to cool slightly. Sprinkle powdered sugar on top before serving for an elegant touch.
