This Flourless Lemon Greek Yogurt Cake is soft, tangy, creamy, and light with a delicate cloud-like texture. It looks like a bakery-style lemon cake, but there is no flour anywhere. Instead, this cake is made with Greek yogurt, eggs, sugar or honey, cornstarch, lemon juice, lemon zest, vanilla, and a pinch of salt.
The texture is somewhere between a soft cheesecake, a soufflé cake, and a tender lemon custard slice. Greek yogurt gives the cake its creamy body and refreshing tang, while whipped egg whites help create a light, airy lift. Lemon juice and zest add bright citrus flavor, and cornstarch helps the cake set without using flour.
This recipe is perfect for spring desserts, brunch, afternoon tea, summer gatherings, or whenever you want something sweet but not too heavy. After baking, the cake cools slowly, then chills in the refrigerator so the slices become clean, smooth, and bakery-worthy.
Serve this flourless lemon Greek yogurt cake with fresh berries, powdered sugar, honey drizzle, whipped cream, mint leaves, hot tea, or iced coffee.

How to Make Flourless Lemon Greek Yogurt Cake
1. Heat the Oven
Preheat your oven to 325°F / 165°C. A moderate oven temperature helps the cake bake gently and keeps the texture soft and creamy.
2. Prep the Pan
Line a 7-inch or 8-inch springform pan with parchment paper and lightly grease the sides. This makes it easier to remove the cake after chilling.
3. Separate the Eggs
Place the egg yolks in one bowl and the egg whites in another clean bowl. Make sure the egg white bowl is free of grease or yolk so the whites whip properly.
4. Mix the Yogurt Base
In a large bowl, whisk together the Greek yogurt, egg yolks, sugar or honey, cornstarch, lemon juice, lemon zest, vanilla, and salt until smooth.
5. Whip the Egg Whites
Beat the egg whites until soft peaks form. They should look fluffy and hold gentle peaks without becoming dry.
6. Fold Gently
Fold the whipped egg whites into the yogurt mixture in 2–3 additions. Use gentle motions so the batter stays airy and light.
7. Pour Into Pan
Pour the batter into the prepared springform pan and smooth the top with a spatula.
8. Bake Until Set
Bake for 40–50 minutes, or until the top is lightly golden and the center still has a soft jiggle. The cake will continue to set as it cools.
9. Cool Slowly
Turn off the oven, crack the oven door open, and let the cake sit inside for 10 minutes. This helps reduce sudden temperature changes and keeps the cake from sinking too quickly.
10. Chill Before Slicing
Cool the cake completely at room temperature, then refrigerate for at least 2 hours. Chilling helps the cake firm up and gives you clean slices.
11. Decorate and Serve
Dust with powdered sugar, add fresh berries, spoon on a Greek yogurt topping, or drizzle with lemon glaze before serving.
Best Tip for a Soft Cloud Slice
Fold the whipped egg whites gently and do not overbake the cake. The center should still have a soft jiggle when it comes out of the oven. After chilling, the texture becomes creamy, smooth, and sliceable.
Serving Suggestions
Serve this cake chilled with fresh blueberries, raspberries, strawberries, or blackberries. A light powdered sugar dusting gives it a bakery-style look, while extra lemon zest adds fresh citrus aroma.
For a sweeter finish, drizzle each slice with honey or lemon glaze. For a creamy topping, add whipped cream, Greek yogurt, or a spoonful of vanilla yogurt.
This cake pairs beautifully with hot tea, iced coffee, espresso, lemonade, or a fresh mint garnish.
Tips and Variations
Use full-fat Greek yogurt for the richest texture.
Use thick plain Greek yogurt, not regular runny yogurt.
Whip the egg whites only to soft peaks so they fold easily.
Fold gently to keep the batter airy.
Use fresh lemon juice and zest for the brightest flavor.
Add blueberries or raspberries before baking for a fruity version.
Add almond extract for a bakery-style flavor twist.
Chill fully before slicing for the cleanest pieces.
Use honey for a softer sweetness or sugar for a more classic cake flavor.
Storage and Reheating
Store leftover cake covered in the refrigerator for up to 4 days. Keep it chilled until ready to serve.
This cake is best served cold or slightly cool. It does not need reheating.
For longer storage, freeze individual slices in airtight containers for up to 1 month. Thaw overnight in the refrigerator before serving. The texture may become slightly softer after freezing, but it will still taste delicious.
Frequently Asked Questions
Is this lemon Greek yogurt cake really flourless?
Yes. This cake is made without wheat flour, almond flour, oat flour, or cake flour. Cornstarch helps the cake set while keeping the texture soft and smooth.
Does it taste like Greek yogurt?
It has a light Greek yogurt tang, but the lemon juice, lemon zest, vanilla, and sweetener give it a fresh dessert flavor.
Can I use honey instead of sugar?
Yes. Honey works well and gives the cake a softer, floral sweetness. Sugar gives a slightly more classic cake-like flavor.
Can I add berries?
Yes. Blueberries and raspberries are especially good with lemon. Fold them in gently or scatter them over the top before baking.
Why did my cake sink?
A little sinking is normal with yogurt and egg-based cakes. Sudden temperature changes, overmixing, or under-whipped egg whites can cause more sinking.
Can I make this ahead of time?
Yes. This cake is perfect for making ahead because it needs at least 2 hours to chill before slicing.
