There's something almost unbelievable about a cake that comes together from just four things sitting in your fridge and pantry right now. No flour, no butter, no mixer even required if your whisking arm is up for it. This high-protein yogurt cake tastes like a cross between cheesecake and custard, with a soft, jiggly center and a lightly golden top, and it's built almost entirely from Greek yogurt and eggs.
If you've been craving something sweet but don't want the sugar crash or the guilt, this one's worth keeping on repeat. It's naturally gluten-free, it's genuinely high in protein for a dessert, and it takes about ten minutes of hands-on work.

Ingredients You'll Need
This recipe leans on pantry basics, but a couple of small choices make a real difference in the final texture.
- Plain Greek yogurt (480 g / about 2 cups): Use full-fat or 2% for the creamiest, most stable cake. Nonfat works too, but the texture turns out slightly less rich and a bit more prone to weeping once sliced. Skyr is a good substitute since it's thicker and even higher in protein.
- Large eggs (4): Eggs are what actually set this cake, since there's no flour to hold structure. Bring them to room temperature first, so they blend smoothly into the yogurt instead of seizing up.
- Honey (1/3 cup): This is both the sweetener and part of what gives the top its light golden color. Maple syrup is a fine one-for-one swap if you want a different flavor note or a vegan-friendlier option.
- Cornstarch (3 tbsp): This is the ingredient that keeps the cake from turning into sweetened baked yogurt. It firms the batter just enough to slice cleanly while keeping the crumb soft. Arrowroot starch works as a substitute in the same amount.
A note on optional add-ins: vanilla extract, lemon zest, or a pinch of cinnamon are common flavor boosters, but they're extras rather than part of the core four-ingredient formula, so add them only if you want a change of pace.
Step-by-Step Instructions
1. Preheat and prep your pan. Set your oven to 325°F (160°C). Line an 8-inch round cake pan with parchment paper, letting the sides overhang slightly so you can lift the cake out later.
2. Whisk the eggs and honey. In a large mixing bowl, whisk the eggs and honey together until the mixture looks smooth and slightly pale, about a minute of steady whisking.
3. Add the yogurt. Add the Greek yogurt to the egg mixture and whisk until fully combined and no streaks remain. The batter should look thick but pourable, similar to pancake batter.
4. Sift in the cornstarch. Sift the cornstarch directly over the batter, then whisk again until completely smooth with no lumps. Sifting matters here since cornstarch clumps easily and lumps won't fully dissolve later.
5. Bake. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 40 to 45 minutes, until the edges are set and lightly golden but the center still has a gentle jiggle when you nudge the pan. It will firm up further as it cools.
6. Cool and chill. Let the cake cool in the pan at room temperature for about 30 minutes, then transfer it to the fridge and chill for at least 3 hours, or ideally overnight. This chilling step is what gives the cake its final custardy, sliceable texture, so don't skip it.
Tips for Best Results
Room-temperature ingredients matter more than people expect in a recipe this simple. Cold eggs straight from the fridge don't blend as smoothly into thick yogurt, and you can end up with small streaks that never fully disappear. Give both the eggs and yogurt about 20 minutes on the counter before you start.
Watch the bake, not just the clock. Ovens vary, and this cake goes from perfectly jiggly to overbaked fairly quickly in the last five minutes. Pull it when the edges look set, and the very center still wobbles slightly, since carryover heat finishes the job as it cools.
Don't skip the chilling time. This is the single most common reason people end up with a cake that's too soft to slice. The starch and egg structure need that cold rest to fully firm up, so resist cutting into it while it's still warm.
If you want a slightly sweeter cake, you can add an extra tablespoon or two of honey without changing the texture much. For a tangier, less sweet version, reduce the honey slightly and let the yogurt's flavor lead.
Use a water bath if your oven runs hot or if you've had cracking issues with custard-style bakes before. Simply set the cake pan inside a larger roasting pan with an inch of hot water and bake as directed. It's not required, but it does produce an even gentler, crack-free finish.
Pan size changes the outcome more than most people expect. A smaller pan, like a 6-inch, gives you a taller cake with more of that dense, custardy center, while a wider pan spreads the batter thinner and bakes faster with a slightly firmer bite throughout. If you swap pan sizes from the one listed here, start checking for doneness about 10 minutes early.
A common mistake is opening the oven door repeatedly to check the cake. Because there's no flour to add structure, this batter is more sensitive to temperature swings than a standard cake, and a sudden cold draft partway through baking can cause the center to sink slightly as it cools. Try to only check it once, near the end of the bake time.
Storage and Reheating
Store leftover cake covered in the refrigerator for up to 4 days. Because it's essentially a yogurt and egg custard, it needs to stay cold rather than sitting out at room temperature.
This cake isn't meant to be reheated. Its appeal is the cool, creamy texture, and heating it will change the structure and make it watery. If you'd like it slightly less cold, just let a slice sit on the counter for 10 minutes before eating.
For longer storage, you can freeze individual slices wrapped tightly in plastic wrap for up to 1 month. Thaw overnight in the fridge before serving. The texture softens very slightly after freezing, but it still slices and tastes great.
Frequently Asked Questions
Can I use flavored yogurt instead of plain? You can, but it will change the sugar content and overall flavor balance, so you'll want to reduce or skip the honey depending on how sweet the yogurt already is. Plain yogurt gives you the most control.
Why did my cake crack on top? Cracking usually means the oven ran a bit too hot or the cake baked a little too long. A slightly lower temperature and pulling it while the center still jiggles will help, and a water bath prevents most cracking altogether.
Can I make this without any sweetener? Yes, you can leave the honey out entirely for a fully unsweetened, savory-leaning yogurt cake, though most people find it noticeably tangy without any sweetness at all.
Is this cake actually high in protein? Yes. Because the base is almost entirely Greek yogurt and eggs rather than flour and butter, each slice delivers more protein than a traditional cake, making it a reasonable option for a protein-focused snack or light dessert.
Can I double the recipe? You can, but use a larger pan, such as a 9- or 10-inch round, rather than a deeper 8-inch pan, or the center may not set properly within a similar bake time. Add a few extra minutes to the bake and watch for the same jiggly-center cue.
Do I need a springform pan? A regular round cake pan works fine as long as it's lined well with parchment, since the parchment overhang is what lets you lift the cake out cleanly once it's chilled.
Can I use a sugar substitute instead of honey? A liquid sweetener like maple syrup swaps in easily since it matches honey's texture and moisture. Granulated or powdered sugar substitutes tend to leave the batter slightly thinner, since you lose the moisture honey provides, so you may need to bake a few minutes longer if you go this route.
Does using low-fat versus full-fat yogurt matter? It affects richness more than it affects whether the cake sets properly. Full-fat or 2% yogurt gives a creamier, more cheesecake-like bite, while nonfat yogurt bakes up a touch firmer and can release more liquid once sliced, so pat any excess moisture away with a paper towel if that happens.
