Contains: Milk · Egg

Whey protein is milk-derived. Chocolate and protein powder formulations vary and may contain soy, gluten, nuts or other allergens, so check the labels of the products you use if those are a concern.

WHY IT WORKS

Why This Recipe Works

01

Whey Without Heaviness

A modest amount of chocolate whey protein adds protein and chocolate flavor without overwhelming the delicate soufflé structure.

02

Stable Egg Whites

Cream of tartar and gradually added sugar help the whipped egg whites hold the air that gives the soufflés their rise.

03

Chocolate Base

Semisweet chocolate and cocoa give the base enough depth that the finished dessert tastes distinctly chocolatey rather than mainly of protein powder.

  1. Heat the oven to 400°F. Put four 6-ounce ramekins on a rimmed baking sheet. Brush the insides with the softened butter using upward strokes, then coat them with the 2 tablespoons (tbsp) granulated sugar and tap out the excess.
  2. Heat the milk until steaming but not boiling. Pour it over the chopped chocolate in a medium heatproof bowl and leave for 1 minute. Whisk until smooth, then whisk in the whey protein powder, cocoa powder and salt. Let the base cool for about 5 minutes.
  3. Whisk the egg yolks and vanilla into the chocolate base until smooth. The mixture should be warm or lukewarm rather than hot before the egg whites are added.
  4. In a clean large bowl, beat the egg whites and cream of tartar on medium speed until foamy and beginning to hold soft peaks. Gradually add the 1/4 US cup granulated sugar and continue beating until the whites are glossy and hold medium-stiff peaks with tips that bend slightly.
  5. Fold about one-third of the whipped egg whites into the chocolate base to lighten it. Fold in the remaining whites in two additions with broad, gentle strokes, stopping as soon as no obvious white streaks remain.
  6. Divide the batter evenly among the prepared ramekins, filling them nearly to the top. Level the surfaces gently, then run a clean fingertip around the inside edge of each ramekin to make a shallow channel between the batter and the rim.
  7. Bake for 12 to 14 minutes without opening the oven door during the first 10 minutes. The soufflés should be well risen with set-looking tops and a slight tremble at the center. Serve immediately.

COOKING GUIDANCE

Practical Cooking Notes

Doneness

The soufflés are ready when they are well risen, the tops look set and the centers still have a slight tremble. Serve immediately because they naturally begin to settle after baking.

Make Ahead

Coat the ramekins and prepare the chocolate base up to 1 day ahead, then cover and refrigerate them separately. Let the base lose its refrigerator chill before folding in freshly whipped egg whites and baking.

Recipe Notes

Ingredient Notes

Chocolate whey protein powders vary in sweetness, cocoa content and thickening power. A standard chocolate whey powder works well here; if yours makes the base unusually stiff, whisk in 1 tablespoon (tbsp) extra milk before folding in the egg whites. Use room-temperature egg whites for easier whipping.

Useful Substitutions

Bittersweet chocolate can replace the semisweet chocolate in the same quantity for a darker, less-sweet result. Two-percent milk can replace whole milk, although the soufflés will be slightly less rich.

INGREDIENT QUALITY

Quality Note

Protein powders vary considerably. The chocolate base should be smooth and spoonable rather than paste-like before the egg whites are folded in; add a small splash of milk if your whey powder thickens it excessively.

COOKING TIPS

Tips

Prepare the Ramekins Well

Brush the butter upward along the sides, then coat with sugar. The textured coating gives the batter something to grip as it rises.

Stop at Medium-Stiff Peaks

Beat the egg whites until glossy peaks hold their shape but still bend slightly at the tips. Very dry whites are harder to fold without losing volume.

Fold Gently

Use broad strokes and turn the bowl as you fold. Stop as soon as no obvious white streaks remain so the batter keeps as much air as possible.

Serve Straight Away

Soufflés begin to settle after they leave the oven. Bring them to the table immediately for the best height and lightest texture.

MAKE IT LAST

Storing, Freezing & Reheating

Storing

These soufflés are best eaten immediately. If needed, refrigerate cooled leftovers in a covered container within 2 hours and use them within 2 days; they will collapse as they cool.

Reheating

Warm a leftover soufflé briefly in the microwave until heated through. It will soften and warm but will not regain its original rise.

QUESTIONS

Chocolate Whey Soufflé FAQs

What kind of whey protein should I use?

Use a chocolate whey protein powder that you already like the flavor of. Powders vary in sweetness and thickening power, so a very thick blend may need a small splash of extra milk.

Why did my soufflé fall?

Some settling is normal as soon as a soufflé leaves the oven. Excessive collapse can come from underbaking, overmixing after the egg whites are added or opening the oven too early.

Can I make chocolate whey soufflés ahead of time?

You can prepare the chocolate base and the coated ramekins ahead, but whip and fold in the egg whites shortly before baking for the best rise.

Can I bake this as one large soufflé?

A larger dish would need a different baking time and behaves differently in the center, so this version is written for four individual ramekins.

Can I reduce or replace the sugar?

The sugar does more than sweeten the dessert: it also helps stabilize the whipped egg whites and contributes to texture. Reducing it substantially or replacing it with a different sweetener would need separate testing.
