If you’re looking for a dessert that is high in protein, low in carbohydrates, keto-friendly, and calorie-conscious, this High-Protein Keto Greek Yogurt Cake is the perfect recipe. Unlike many keto cakes that rely heavily on butter, cream cheese, and large amounts of almond flour, this version is specifically formulated to keep calories under control while still delivering a moist texture, satisfying flavor, and excellent protein content.
The secret lies in using non-fat Greek yogurt, egg whites, and protein powder as the primary structure-building ingredients. These additions dramatically increase protein while keeping fat and calories lower than traditional keto desserts. The result is a soft, lightly sweet cake that can be enjoyed as a healthy breakfast, post-workout snack, afternoon treat, or guilt-free dessert.
This recipe is designed to be baked in an 8-inch round cake pan and cut into 12 equal slices. Portion size matters significantly because the nutritional values are based on dividing the cake into exactly 12 servings. Each slice delivers approximately 90 calories while providing satisfying protein and very few net carbohydrates.

Why This Recipe Stays Around 90 Calories Per Slice
One of the biggest challenges when creating keto desserts is controlling calories while maintaining a satisfying texture. Traditional keto cakes often contain large amounts of butter, cream cheese, almond flour, and heavy cream, which can push calories very high.
This recipe uses several calorie-conscious strategies:
Non-Fat Greek Yogurt
Non-fat Greek yogurt replaces many high-fat ingredients while contributing moisture, creaminess, and additional protein.
Egg Whites
Using three egg whites instead of additional whole eggs reduces fat and calories while still providing structure and lift.
Limited Added Fat
Only two tablespoons of butter or coconut oil are used in the entire cake, helping keep calories lower than many keto baked goods.
Protein Powder
Protein powder increases volume, texture, and satiety while contributing minimal carbohydrates.
Reduced Almond Flour
The almond flour quantity is intentionally reduced and balanced with protein powder and coconut flour to lower calories while maintaining a cake-like texture.
Preparation Instructions
Step 1: Preheat the Oven
Preheat your oven to 325°F (165°C).
Lightly grease an 8-inch round cake pan and line the bottom with parchment paper. This helps prevent sticking and makes removal easier after baking.
Step 2: Mix the Dry Ingredients
In a medium mixing bowl, combine:
- Almond flour
- Coconut flour
- Protein powder
- Baking powder
- Baking soda
- Salt
Whisk thoroughly until all ingredients are evenly distributed. Be sure to break apart any clumps from the protein powder to ensure a smooth batter.
Step 3: Prepare the Wet Ingredients
In a large bowl, whisk the egg whites until slightly foamy. There is no need to whip them to stiff peaks.
Add the whole egg and whisk again until combined.
Stir in the non-fat Greek yogurt until completely smooth and creamy.
Add the sweetener, melted butter or coconut oil, and vanilla extract.
Continue mixing until all wet ingredients are fully incorporated.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture.
Using a spatula, gently fold everything together until no dry pockets remain.
The batter should appear thick yet airy. Avoid overmixing, as excessive stirring may result in a denser cake.
Step 5: Rest the Batter
Allow the batter to rest for 3 to 5 minutes.
This resting period allows the coconut flour and protein powder to absorb moisture, improving the final texture and preventing dryness.
Step 6: Transfer to the Pan
Spread the batter evenly into the prepared cake pan.
Use a spatula to smooth the surface.
Gently tap the pan against the countertop several times to release trapped air bubbles and create an even bake.
Baking Instructions
Place the cake into the preheated oven and bake for 35 to 45 minutes.
Begin checking at the 35-minute mark.
Insert a toothpick into the center of the cake. It should come out mostly clean with only a few moist crumbs attached.
If the top begins browning too quickly before the center is fully baked, loosely cover the cake with aluminum foil and continue baking until done.
Once baked, remove the cake from the oven and place it on a cooling rack.
Allow it to cool in the pan for approximately 20 minutes before removing.
Cooling Is Critical
This step is extremely important for achieving the best texture.
Because this recipe relies heavily on protein powder, Greek yogurt, and egg whites, the cake continues setting as it cools.
Avoid slicing while hot.
For optimal texture, refrigerate the cake for at least 1 hour after cooling.
The chilling process allows the protein structure to fully stabilize, resulting in a firmer, more satisfying cake.
Optional Low-Calorie Topping Ideas
To maintain the low-calorie profile, choose toppings carefully.
Powdered Sweetener Dusting
A light dusting of powdered erythritol adds sweetness with virtually no calories.
Sugar-Free Syrup
A small drizzle of sugar-free syrup can add flavor while keeping calories minimal.
Vanilla Greek Yogurt Topping
Mix non-fat Greek yogurt with a few drops of vanilla extract for a creamy, protein-rich topping.
Avoid calorie-dense toppings such as nut butters, whipped cream, heavy cream frosting, chocolate spreads, or large amounts of nuts if your goal is to keep servings around 90 calories.
Storage Instructions
Store the cake in an airtight container in the refrigerator for up to 5 days.
For longer storage, wrap individual slices and freeze for up to 1 month.
Thaw overnight in the refrigerator or enjoy slightly chilled directly from the fridge.
Many people find the texture even better on the second day after the flavors have fully developed.

Frequently Asked Questions
Can I use full-fat Greek yogurt?
You can, but doing so will increase calories and fat significantly. Non-fat Greek yogurt is recommended to maintain the intended nutrition profile.
Which protein powder works best?
Whey isolate generally produces a lighter texture, while casein creates a slightly denser and more moist cake. Both work well.
Can I make this recipe dairy-free?
You may substitute dairy-free yogurt and plant-based protein powder, though texture and nutritional values will vary.
Why is my batter thicker than regular cake batter?
Protein powder and coconut flour absorb a large amount of moisture, creating a thicker batter than traditional cakes.
Can I add chocolate flavor?
Yes. Replace 2 tablespoons of almond flour with unsweetened cocoa powder for a chocolate version while keeping calories relatively similar.
Is this recipe suitable for keto diets?
Yes. The cake is low in carbohydrates and uses keto-friendly ingredients, making it suitable for most ketogenic eating plans.
Can I use only egg whites?
Yes. Replacing the whole egg with additional egg whites will further reduce fat and calories, although the cake may be slightly less rich.
Why must the cake be cut into 12 slices?
The nutritional information is based on 12 equal servings. Larger slices will naturally contain more calories and macros.
