Cooking Methods

  • No-cook recipe

Preparation Steps

  1. Measure out the heavy cream, sweetener, and vanilla extract.
  2. If using almond milk or water, set it aside for later.

Instructions steps

  1. Combine the heavy cream, powdered sweetener, and vanilla extract in a small bowl or mason jar.
  2. Use a milk frother or handheld whisk to whip the mixture until it forms soft peaks (about 30-45 seconds).
  3. If the foam is too thick, add 1 tablespoon of almond milk or water at a time to reach your desired texture.

Chef's pro tip

For extra fluffiness, chill your heavy cream and mixing bowl before whipping. This helps the foam form faster and stay airy longer. If you whip too much, the foam becomes too thick and loses its airy consistency. Adding a little unsweetened almond milk can help thin it out if you prefer a lighter texture.

How to Make It Healthier

Want a lower-calorie version? Swap half of the heavy cream for unsweetened almond milk to keep the foam light and keto-friendly.

Time-Saving Tips

  • If you frequently make keto coffee recipes, store a bottle of keto vanilla syrup for quick flavor boosts.

What Can I Prepare Ahead of Time?

  • Mix the cream, sweetener, and vanilla extract ahead of time and store it in the refrigerator. When ready to use, give it a quick whip with the frother to restore the airy consistency.
