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

Ingredient Notes

Greek yogurt adds moisture and a mild tang that complements the lemon flavor. Using plain rather than flavored yogurt is important to keep the sweetness balanced. For the cake mix, a classic lemon-flavored one works best here. If you don’t have lemon zest or want a subtler flavor, you can leave it out—the cake is still delicious. Freshly zested lemon gives a bright, natural lemon note that enhances the cake without making it bitter or artificial.

Kitchen Tools Needed

8-inch (20 cm) square baking pan
Mixing bowl
Whisk or fork
Spatula
Microplane or fine grater (for zesting lemon)
Toothpick or cake tester

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease the 8-inch square pan generously or line it with parchment paper to prevent sticking. This step makes cleanup easier and helps the cake release smoothly.
In a medium bowl, whisk together the plain Greek yogurt and eggs until the mixture is smooth and slightly frothy. The eggs help the cake rise and create airiness, while whisking well ensures an even texture.
Gently stir in the lemon cake mix along with the optional lemon zest. Combine just until no dry streaks remain—overmixing can lead to a denser cake. You want a batter that’s thick but pourable.
Pour the batter into the prepared pan, smoothing the top evenly with a spatula. This helps the cake bake uniformly without cracking or bulging in spots.
Bake for 25 to 30 minutes. Begin checking at 25 minutes with a toothpick inserted into the center—if it comes out clean or with a few moist crumbs, the cake is done. Don’t open the oven too often to maintain even baking.
Remove the cake from the oven and leave it to cool in the pan completely. Cooling fully helps the cake set so it slices nicely and doesn’t crumble apart.

Pro Tips

Don’t skip greasing or using parchment paper—this simple step keeps your cake edges clean and intact.
Use room temperature eggs for easier mixing and a better rise.
If you want a more intense lemon flavor, add 1/2 teaspoon lemon extract along with the zest.
Avoid overmixing the batter once the cake mix is added; it keeps the texture light and tender.
Letting the cake cool fully before slicing prevents the crumb from falling apart, so plan accordingly.

Common Mistakes

Using cold eggs or yogurt can make the batter uneven and affect rising.
Overmixing after adding the cake mix will produce a tough and dense cake.
Baking for too long dries out this moist cake, so start checking at 25 minutes.
Not greasing the pan well enough can cause the cake to stick and break during removal.
Cutting the cake while it’s still warm might result in crumbly slices.

Variations

Add 1/2 cup (75 g) fresh blueberries or raspberries to the batter for a fruity twist.
Stir in 1/4 cup (25 g) chopped toasted almonds or pecans for crunch.
Use orange zest instead of lemon for a different citrus flavor.
Top with a simple glaze made from powdered sugar and lemon juice for extra sweetness and shine.

Serving Suggestions

Serve slices plain or with a dusting of powdered sugar. This cake pairs wonderfully with a dollop of whipped cream or a scoop of vanilla ice cream for a light dessert. For a casual treat, a cup of tea or coffee complements the gentle lemon taste perfectly.

Storage Instructions

Wrap leftover cake tightly in plastic wrap or store in an airtight container. It can be kept at room temperature for up to 2 days or refrigerated for up to 5 days without drying out.

Reheating Tips

This cake is best enjoyed at room temperature. If reheating, warm gently in the microwave for 10-15 seconds to soften slightly, but avoid overheating as it can dry out quickly.
