Marshmallow-Style • Fluffy • Glossy • Lighter Sugar • Protein-Boosted
This is a high-protein remake of the classic 7-Minute Frosting you see in the image—light, glossy, and cloud-like, with that nostalgic marshmallow-cream flavor.
It keeps the look and texture of the original but adds extra protein and reduces the sugar load, making it more balanced and modern.
Perfect for:
- Cakes & cupcakes
- Layer cakes
- Cake rolls
- Dessert jars
- Even as a marshmallow-style dip
⏱ Servings & Timing
- Yield: Frosts 1 large cake or 12–18 cupcakes
- Prep Time: 5 minutes
- Cook/Whip Time: 7–8 minutes
- Total Time: ~15 minutes
🛒 Ingredients (High-Protein Version)
Base
- 4 large egg whites (room temperature)
-
½ cup powdered allulose or powdered monk-fruit blend
(or ¾ cup regular sugar if not sugar-free) - ¼ cup water
-
1 tbsp light corn syrup or sugar-free syrup
(helps stability & shine) - ¼ tsp cream of tartar
Protein Boost (KEY)
-
2–3 tbsp unflavored or vanilla whey protein isolate
(must be whey isolate for smooth texture)
Flavor
- 1½ tsp vanilla extract
- Pinch of salt
👩🍳 Step-by-Step Instructions
1️⃣ Set Up a Double Boiler
- Fill a saucepan with 1–2 inches of water
- Bring to a gentle simmer
- Place a heat-safe glass or metal bowl on top (bottom should not touch water)
2️⃣ Combine Ingredients
In the bowl, whisk together:
- Egg whites
- Sweetener
- Water
- Corn syrup
- Cream of tartar
- Salt
Whisk until foamy (about 30 seconds).
3️⃣ Cook & Whip (The 7-Minute Magic)
Using a hand mixer, beat continuously over simmering water for 6–7 minutes until:
- Volume triples
- Frosting turns bright white
- Stiff, glossy peaks form
👉 It should look exactly like marshmallow cream.
4️⃣ Add Protein (IMPORTANT STEP)
- Lower mixer speed
- Sprinkle in protein powder slowly
- Beat until fully incorporated and silky
⚠ Do NOT dump protein in all at once—this prevents graininess.
5️⃣ Finish
Remove from heat.
Beat in vanilla extract for 30 seconds.
Your frosting should be:
✔ Ultra-fluffy
✔ Glossy
✔ Spoon-standing
✔ Marshmallow-soft
🧁 How to Use
- Frost immediately while warm
- Pipe onto cupcakes
- Spread on cakes
- Torch lightly for a toasted marshmallow effect
