Flourless Sour Cream Cake
This sour cream cake gives you a creamy, golden dessert with no flour, no kneading, and no egg separating.
It lands somewhere between a soft cake, baked custard, and simple cheesecake. The top turns deeply golden, while the inside stays smooth, rich, and tender. You only need a handful of everyday ingredients, one bowl, and a baking dish.
Why You’ll Love This Recipe
- Ultra creamy texture: Sour cream and eggs bake into a soft custard-like center that slices cleanly after cooling.
- No flour needed: Cornstarch helps the cake set, so the result stays light, smooth, and naturally gluten-free.
- Simple mixing: You whisk everything in one bowl, pour it into a pan, and let the oven do the work.
- Budget-friendly dessert: Eggs, sour cream, sugar, cornstarch, and vanilla make a beautiful treat without expensive extras.
Fabian’s Budget Tip: Use store-brand sour cream for this cake. Since the recipe bakes the sour cream into a custard style filling, you do not need a premium brand. If vanilla extract is costly, vanilla sugar works well and still gives the cake a warm bakery aroma.
Ingredients (Serves 4)
- 6 large eggs
- 3 3/4 cups sour cream (900 g)
- 2/3 cup granulated sugar (140 g)
- 1/2 cup plus 2 tablespoons cornstarch (75 g)
- 1 teaspoon vanilla extract or vanilla sugar (5 ml)
- Butter or neutral oil for greasing the pan, optional
- Fresh berries, for serving, optional
- Powdered sugar, for serving, optional
Step-by-Step Instructions
1. Heat the Oven
Preheat the oven to 355°F (180°C). Lightly grease an 8 inch round cake pan or a small baking dish if you want easier slicing. A dish with a little depth works best because the batter bakes into a creamy custard style cake.
2. Whisk the Eggs, Sugar, Cornstarch, and Vanilla
Add the eggs, sugar, cornstarch, and vanilla to a large mixing bowl. Whisk until the mixture looks smooth and pale. Scrape the sides of the bowl so no dry cornstarch hides at the edges. The batter should feel silky, not gritty.
3. Mix in the Sour Cream
Add the sour cream to the bowl. Whisk until fully combined. The batter will look loose and creamy, almost like thick pourable custard. Take a moment here, because smooth batter gives the cake its best texture.
4. Pour and Settle the Batter
Pour the mixture into the prepared pan. Tap the pan gently on the counter a few times to release large air bubbles. The surface should look even and glossy before it goes into the oven.
5. Bake Until Deeply Golden
Bake for about 1 hour. The top should turn a rich golden brown, and the edges should look set. The center should still have a gentle wobble, like baked cheesecake, but it should not look liquid. Your kitchen will smell warm, sweet, and lightly tangy from the sour cream and vanilla.
6. Cool Completely Before Slicing
Let the cake cool completely in the pan. This step matters. The cake firms as it cools, so slicing too early can make it collapse or look wet. Serve it chilled or at room temperature with fresh berries and a light dusting of powdered sugar.
Expert Troubleshooting and FAQs
Why did my sour cream cake crack on top?
A few cracks are normal because this cake is rich with eggs and dairy. If the cracks are deep, the oven may have been too hot. Bake on the middle rack and avoid opening the oven door too often.
How do I know when the center is set?
Gently shake the pan. The edges should stay firm, while the center gives a soft jiggle. If the center moves like liquid, bake for another 5 to 10 minutes and check again.
Can I make this cake ahead of time?
Yes. This cake tastes even better after chilling for several hours. The texture becomes creamier, and the vanilla flavor settles into the sour cream base.
Can I use low-fat sour cream?
You can, but the cake may taste less rich and may set a little softer. Full fat sour cream gives the creamiest texture and the cleanest slices.
Why is my cake watery after baking?
It may not have baked long enough, or it may have been sliced while still warm. Let the cake cool fully, then chill it if needed. Cornstarch needs heat and cooling time to help the custard set.
