Why You’ll Love This Flourless Lemon Cake

1. Light Yet Decadent Texture: Because this cake relies on cornstarch (or tapioca starch) and egg structure instead of heavy wheat flour, the result is somewhere between a delicate sponge and a rich lemon cheesecake.

2. Protein-Boosted: Whole milk or 2% Greek yogurt adds creamy moisture, tangy flavor depth, and a wholesome protein bump.

3. Naturally Gluten-Free: Perfect for family members or guests with gluten sensitivities.

4. Vibrant Citrus Flavor: Uses both fresh lemon zest and fresh-squeezed juice for an authentic, sunshiny bite—no artificial extracts needed!

Ingredients Checklist

For the Flourless Lemon Cake:

• 4 large eggs (at room temperature, whites and yolks separated)

• 1 cup (240g) plain Greek yogurt (full-fat or 2% recommended for best texture)

• 1/3 cup (80ml) pure maple syrup or honey (or sub liquid sweetener of choice)

• 3 tablespoons (45ml) fresh lemon juice (approx. 1 medium lemon)

• 1 tablespoon finely grated lemon zest (packed)

• 6 tablespoons (45g) cornstarch (or arrowroot starch / tapioca flour)

• 1 teaspoon pure vanilla extract

• 1/2 teaspoon baking powder

• 1/4 teaspoon fine salt

For the Optional Lemon Glaze & Garnish:

• 1/2 cup powdered sweetener (powdered sugar or powdered erythritol)

• 1 to 2 tablespoons fresh lemon juice

• Fresh mint leaves, fresh berries, or powdered sugar dusting for serving

Step-by-Step Instructions

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Line the bottom of an 8-inch round cake pan with parchment paper, then lightly grease the sides with coconut oil, butter, or non-stick cooking spray.

Step 2: Separate and Beat the Egg Whites

Carefully separate the egg whites from the yolks into two clean mixing bowls. Using an electric hand mixer or stand mixer fitted with the whisk attachment, beat the egg whites on medium-high speed for 3 to 4 minutes until soft, stable peaks form. Set aside.

Step 3: Whisk the Liquid Base & Yolks

In the bowl containing the egg yolks, add the Greek yogurt, maple syrup (or honey), fresh lemon juice, lemon zest, and vanilla extract. Whisk vigorously for 1 to 2 minutes until smooth, creamy, and pale yellow.

Step 4: Sift in Dry Ingredients

Sift the cornstarch, baking powder, and salt directly into the wet yolk mixture. Whisk gently until fully combined and no powdery lumps remain.

Step 5: Gently Fold the Egg Whites (Crucial for Lift)

Add one-third of the beaten egg whites to the yolk batter. Gently whisk or stir to lighten the mixture. Next, scoop the remaining egg whites into the bowl. Using a silicone spatula, fold delicately in a sweeping down-across-and-up motion until no white streaks remain. Take care not to overmix, as keeping the trapped air ensures a light structure!

Step 6: Bake to Golden Perfection

Pour the batter into your prepared pan, smoothing the top with your spatula. Bake at 350°F (175°C) for 40 to 45 minutes, or until the center is set (it should gently jiggle when shaken, but shouldn’t look wet) and the top turns light golden-brown.

Step 7: Cool and Chill

Transfer the cake to a wire rack and let it cool in the pan for 30 minutes. As it cools, the cake will set further. For the cleanest slices and best cheesecake-like texture, refrigerate the cake for at least 1 hour before unmolding and serving.

Storage & Freezing Instructions

• Refrigeration: Store leftover cake wrapped tightly or in an airtight container in the refrigerator for up to 4–5 days. Enjoy cold or bring to room temperature before eating.

• Freezing: Wrap individual slices tightly in plastic wrap and store in a freezer-safe bag for up to 2 months. Thaw in the fridge overnight before serving.
