3-Ingredient Lemon Yogurt Cake

Sometimes you just want a dessert that’s quick, fuss-free, and still tastes like you made something special. This lemon yogurt cake hits that sweet spot perfectly. With just three simple ingredients—and a little optional lemon zest—it comes together in minutes and bakes into a moist, tender cake with a bright, fresh citrus flavor. Using plain Greek yogurt keeps the texture delightfully creamy without any added oil or butter, while the eggs and ready-made lemon cake mix do most of the work for you.

This cake is a great go-to when you want something homemade without a long ingredient list or complicated steps. It’s also forgiving; mixing just until combined means you avoid overworking the batter, resulting in a soft crumb and lovely rise. I find baking it about 28 minutes works best for my oven, giving a perfect golden top and clean toothpick test. Letting it cool fully before slicing helps keep the pieces neat and makes the flavor even better.

Ingredients

• 1 cup (240 ml) plain Greek yogurt
• 3 large eggs
• 1 box (13 to 15 oz / 368 to 425 g) lemon cake mix
• Optional: Zest of 1 lemon for extra brightness

Ingredient Notes

Using plain Greek yogurt adds moisture and a bit of tang, which brightens the flavor and keeps the cake from drying out. Avoid flavored yogurts as they can throw off the balance. The lemon cake mix provides both the flour, sugar, and lemon flavor, so there’s no need to add extra sugar or flour. Adding fresh lemon zest is optional but really lifts the cake with a subtle, fresh citrus note, especially if your cake mix isn’t very lemony.

Kitchen Tools Needed

• 8-inch (20 cm) square baking pan
• Whisk or fork
• Mixing bowl
• Measuring cups and spoons
• Toothpick or cake tester

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C). Grease the 8-inch square pan well or line it with parchment paper to ensure easy removal.
2. In a mixing bowl, whisk together the Greek yogurt and eggs until smooth and slightly frothy—this helps with a light texture.
3. Stir in the lemon cake mix and optional lemon zest. Mix gently just until you no longer see dry spots. Overmixing can make the cake tough.
4. Pour the batter into the prepared pan, smoothing the top with a spatula or back of a spoon.
5. Bake for 25 to 30 minutes. Start checking at 25 minutes by inserting a toothpick in the center—it should come out clean or with just a few moist crumbs attached. The top should be golden but not dark.
6. Remove from the oven and let cool completely on a wire rack before slicing. This step helps the cake set nicely and makes cleaner slices.

Pro Tips

• For a brighter lemon punch, zest the lemon before juicing (if you decide to add juice later).
• Don’t skip letting the cake cool fully. Warm cake slices can crumble more and seem soggy.
• Stir the batter gently; some lumps are okay, but avoid overmixing to keep the crumb tender.
• Use an oven thermometer if you’re unsure of your oven temperature—350°F (175°C) is key to baking this cake evenly.
• If your cake mix seems too dry when mixing, a tablespoon of milk or water can help without losing texture.
• Greasing and lining the pan gives you the best chance at clean removal and neat slices.

Common Mistakes

• Overmixing the batter can lead to a dense or rubbery texture.
• Baking too long will dry out the cake—check early with a toothpick.
• Using flavored or sweetened yogurt can make the cake overly sweet or change the flavor profile.
• Not greasing or lining the pan can cause the cake to stick and break apart.
• Cutting the cake before it cools makes it crumbly and harder to serve neatly.

Variations

• Add ½ cup (75 g) fresh or frozen blueberries folded gently into the batter for a fruity twist.
• Stir in ½ teaspoon poppy seeds for a classic lemon-poppyseed flavor combination.
• Swap lemon cake mix for orange or vanilla cake mix with matching zest for a different citrus or sweet note.
• Drizzle a simple glaze of powdered sugar and lemon juice over the cooled cake for extra sweetness and a glossy finish.

Serving Suggestions

This cake shines on its own with a cup of tea or coffee, but you can also dust it with powdered sugar or top each slice with fresh berries and a dollop of whipped cream or a spoonful of Greek yogurt. It’s light enough for an afternoon snack but works well as a simple dessert after dinner.

Storage Instructions

Store leftover cake in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate in an airtight container for up to 5 days. Bring to room temperature before serving to avoid the cake tasting dense or dry.

Reheating Tips

This cake is best enjoyed at room temperature, so reheating isn’t really necessary. If you prefer it warm, microwave a slice for about 15 seconds—just enough to take the chill off without drying it out.

Frequently Asked Questions

Can I use regular yogurt instead of Greek yogurt?
You can, but use a thicker yogurt or drain regular yogurt to remove excess liquid. Greek yogurt helps keep the texture moist without making the batter too runny.

What if I don’t have lemon zest?
It’s totally fine to skip it. The lemon cake mix usually has plenty of lemon flavor. The zest just adds a fresh brightness.

Can I make this cake in a different size pan?
Yes. If you use a larger pan, the cake will be thinner and bake faster. Adjust baking time accordingly and check for doneness early.

Can I add frosting or glaze?
Absolutely. A light lemon glaze or cream cheese frosting pairs well, but the cake is delicious on its own.

Is this cake freezer-friendly?
Yes, wrap pieces tightly in plastic wrap and freeze up to 2 months. Thaw at room temperature before serving.
