What You’ll Need

For the Cake:

2 cups (250g) all-purpose flour – creates tender structure
1½ teaspoons baking powder – helps cake rise beautifully
½ teaspoon baking soda – extra lift and tenderness
½ teaspoon salt – enhances all flavors
¾ cup (150g) granulated sugar – just enough for sweetness
1 cup (240g) plain Greek yogurt – fat-free, adds moisture and protein
½ cup (120ml) unsweetened applesauce – replaces oil and adds natural sweetness
4 large egg whites – structure without the fat from yolks
¾ cup (180ml) skim milk – keeps calories low
⅓ cup (80ml) fresh lemon juice – bright, zesty flavor
2 tablespoons lemon zest – from 2-3 large lemons
2 teaspoons vanilla extract – enhances overall flavor
1 tablespoon cornstarch – helps create tender crumb

Low Calorie Glaze (Optional):

1 cup powdered sugar – sifted
3-4 tablespoons fresh lemon juice – adjust for consistency
1 teaspoon lemon zest – for extra zing

Calorie-Cutting Substitutions:

Sugar alternatives: Use ¾ cup erythritol or stevia baking blend
Even lower calories: Replace half the flour with almond flour
Dairy-free: Use unsweetened almond milk instead of skim milk

Step-by-Step Directions

Preheat oven to 350°F (175°C). Spray a 9×13 inch pan with cooking spray, then lightly dust with flour. This prevents sticking without adding butter calories.
Prepare the dry ingredients. In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, and cornstarch. The cornstarch is key for creating a tender texture without extra fat.
Mix wet ingredients carefully. In another bowl, whisk together Greek yogurt, applesauce, egg whites, skim milk, lemon juice, lemon zest, and vanilla until completely smooth. Make sure no lumps of yogurt remain.

Pro Tip: Use room temperature ingredients for the smoothest mixing. Cold Greek yogurt can create lumps that are hard to eliminate once flour is added.

Combine wet and dry ingredients. Pour the wet mixture into the dry ingredients and stir just until combined. Don’t overmix—this creates tough cake. A few small lumps are perfectly fine.
Achieve the perfect pour. The batter will be slightly thinner than traditional cake batter due to the Greek yogurt and applesauce. Pour evenly into prepared pan and gently tap on counter to release air bubbles.
Bake to golden perfection. Bake for 32-38 minutes until the top is golden and springs back when lightly touched. A toothpick should come out with just a few moist crumbs—not wet batter.

Doneness Test: The cake is ready when it just begins to pull away from the sides and the center feels firm but not hard when gently pressed.

Cool and finish. Let cake cool completely in the pan before adding glaze or serving. For the glaze, whisk powdered sugar with lemon juice until smooth and drizzle over cooled cake.

Expert Tips for Success

Calorie-Saving Strategies:

Greek yogurt is your secret weapon—it adds protein and moisture while cutting fat calories in half
Don’t skip the applesauce—it keeps the cake moist for days without oil
Use cooking spray instead of butter for greasing pans (saves 100+ calories)

Texture Perfection:

Room temperature ingredients mix more easily and create better texture
Don’t overbake—low fat cakes can dry out quickly
The cornstarch helps create the tender crumb you’d normally get from butter

Make-Ahead Magic:

This cake stays moist for 4 days covered at room temperature
Freeze individual slices wrapped in plastic for portion-controlled treats
Make the glaze just before serving to prevent sogging

Flavor Maximization:

Fresh lemon juice makes all the difference—bottled juice lacks the bright flavor
Add extra lemon zest if you love citrus—it’s virtually calorie-free
Try lime or orange for fun flavor variations

Common Questions

How many calories are really in each slice?

Each generous slice (1/12 of the cake) contains approximately 150 calories, compared to 350-400 calories in traditional cake. The majority of calories come from flour and sugar, with minimal fat calories.

Will this cake taste as good as regular cake?

Absolutely! The lemon flavor is bright and satisfying, while Greek yogurt creates surprising richness. The texture is tender and moist—most people can’t tell it’s the low-calorie version.

Can I use whole eggs instead of just egg whites?

You can, but you’ll add about 25 calories per slice. If you do use whole eggs, use 2 whole eggs instead of 4 egg whites, and the texture will be slightly richer.

How do I store this cake to keep it moist?

Cover tightly with plastic wrap or store in an airtight container. The Greek yogurt and applesauce help maintain moisture much longer than traditional cakes. It actually tastes better on day two!

Can I make this cake even lower in calories?

Yes! Use a sugar substitute like erythritol (saves 50 calories per slice), or replace half the flour with almond flour for added protein and fewer carbs. You could get down to about 120 calories per slice.

What if I don’t have Greek yogurt?

Regular plain yogurt works, but drain it in a fine mesh strainer for 30 minutes first to remove excess liquid. Avoid flavored yogurts as they add unnecessary sugar and calories.
