Ultra-Light, High-Protein, WW-Friendly

A Complete, Detailed Recipe Guide


Introduction

The High-Protein Cloud Cake is designed for people who want a dessert that feels indulgent but aligns with weight-loss, muscle-building, or mindful-eating goals. This cake is exceptionally light, airy, and creamy โ€” closer in texture to a soufflรฉ-cheesecake hybrid than a traditional cake.

What sets this recipe apart is its protein-forward structure combined with a cloud-like crumb. Instead of relying on heavy flour, butter, or oil, the structure comes from whipped egg whites, protein powder, and a small amount of starch. The result is a cake that:

โ€ข is soft and delicate
โ€ข melts in the mouth
โ€ข is lightly sweet, not dense
โ€ข delivers high protein per serving
โ€ข fits Weight Watchers and macro-focused lifestyles

This is not a dry โ€œdiet cake.โ€ It is intentionally designed to feel luxurious while remaining light and functional.

This guide explains how to make it, why it works, how to prevent collapse, how to customize sweetness and macros, and how to store it properly.

Skill Level: Intermediate (technique-based, not difficult)
Total Time: About 90 minutes
โ€ข Prep: 25 minutes

Ingredients and Their Purpose

Cream Cheese

8 oz light cream cheese, softened

Cream cheese provides richness, structure, and moisture without heaviness.

โ€ข Light cream cheese reduces fat while keeping creaminess
โ€ข Must be fully softened to avoid lumps
โ€ข Acts as the โ€œcheesecake baseโ€ of the cake


Greek Yogurt

ยฝ cup plain non-fat Greek yogurt

Greek yogurt adds protein, tang, and moisture.

โ€ข Non-fat keeps points and calories low
โ€ข Adds creaminess without density
โ€ข Helps balance sweetness


Eggs (Separated)

4 large eggs, separated

Eggs are the backbone of this recipe.

โ€ข Yolks add richness and structure
โ€ข Whites provide lift and airiness

Whipped egg whites are responsible for the โ€œcloudโ€ texture. This step is essential.


Whey Protein Powder

ยฝ cup vanilla or unflavored whey protein

Protein powder increases protein content while contributing to structure.

โ€ข Whey is preferred for light texture
โ€ข Vanilla adds flavor; unflavored allows customization
โ€ข Avoid plant protein โ€” it creates density


Sweetener

ยผ cup sugar or zero-calorie sweetener

Sweetener provides balance and stabilizes egg whites.

โ€ข Sugar gives best structure and browning
โ€ข Zero-calorie sweeteners work but require careful folding
โ€ข Powdered versions dissolve more easily


Cornstarch or Oat Flour

2 tablespoons cornstarch or oat flour

This small amount provides stability.

โ€ข Prevents collapse after baking
โ€ข Gives gentle structure without heaviness
โ€ข Cornstarch yields the lightest texture


Milk

ยผ cup milk (almond or dairy)

Milk thins the batter and helps protein powder blend smoothly.

โ€ข Almond milk keeps calories lower
โ€ข Dairy milk adds richness


Vanilla Extract

1ยฝ teaspoons vanilla extract

Enhances flavor and complements protein powder.


Salt

ยผ teaspoon salt

Salt sharpens sweetness and strengthens egg white structure.


Equipment Needed

โ€ข Mixing bowls (2 large, 1 medium)
โ€ข Electric mixer or stand mixer
โ€ข Rubber spatula
โ€ข 8-inch springform or round cake pan
โ€ข Parchment paper
โ€ข Fine mesh sieve (optional)


Step-by-Step Instructions

Step 1: Prepare the Pan and Oven

Preheat oven to 325ยฐF (165ยฐC).

Line the bottom of an 8-inch pan with parchment paper. Lightly grease the sides.

This lower temperature ensures gentle baking and prevents cracking.


Step 2: Make the Base Batter

In a large bowl, add:
โ€ข softened cream cheese
โ€ข Greek yogurt

Beat until completely smooth and lump-free.

Add:
โ€ข egg yolks
โ€ข sweetener
โ€ข vanilla extract

Mix until creamy and uniform.


Step 3: Incorporate Dry Ingredients

Sift together:
โ€ข protein powder
โ€ข cornstarch (or oat flour)
โ€ข salt

Gradually mix into the batter.

Add milk slowly, mixing just until smooth. Do not overmix.

The batter should be thick but pourable.


Step 4: Whip the Egg Whites

In a clean, dry bowl, add egg whites.

Beat on medium speed until foamy, then increase to high speed.

Whip until soft peaks form.

Soft peaks are crucial โ€” stiff peaks make folding difficult and can cause collapse.


Step 5: Fold the Batter

Add โ…“ of the egg whites to the batter and gently mix to loosen it.

Then gently fold in the remaining egg whites in two additions using a spatula.

Use slow, sweeping motions. Preserve as much air as possible.


Step 6: Bake

Pour batter into prepared pan.

Tap lightly once to release large air bubbles.

Bake at 325ยฐF (165ยฐC) for 45โ€“50 minutes.

The cake is done when:
โ€ข top is lightly golden
โ€ข center jiggles slightly
โ€ข edges are set


Step 7: Cooling (Critical Step)

Turn off oven and crack the door open.

Let cake sit inside for 20โ€“30 minutes.

This gradual cooling prevents collapse.

Remove and cool completely at room temperature.
