Ingredients
  

Main
  • 1/2 cup cold milk dairy, oat, almond, or your preferred type
  • 1/4 teaspoon vanilla extract optional
  • 1/2 teaspoon sweetener of choice honey, maple syrup, or simple syrup, optional
  • Pinch of salt optional
  • Cold brew or iced coffee as needed

Equipment

  • Electric hand mixer or stand mixer with whisk attachment
  • Measuring cups and spoons
  • Small mixing bowl or cup
  • Tall glass or coffee cup
  • Spoon or small spatula for scooping foam

Method
 

  1. Measure 1/2 cup of cold milk directly from your refrigerator into a small mixing bowl or measuring cup. Cold temperature is critical because warm milk won't trap air bubbles effectively.
  2. Stir in your vanilla extract, sweetener, and salt if you're using them, making sure everything is fully dissolved before you start mixing.
  3. Attach the whisk attachment to your hand mixer or stand mixer.
  4. Turn your mixer to medium speed and start whisking the cold milk, holding the bowl steady with your other hand if using a hand mixer. You'll notice the milk starting to get foamy almost immediately.
  5. After about 30 seconds, increase the speed to medium-high and keep whisking until you see stiff peaks forming in the foam. This typically takes another 30 to 45 seconds total.
  6. Stop whisking when you can see thick, fluffy peaks that hold their shape when you lift the whisk out of the bowl.
  7. Pour your cold brew or iced coffee into a tall glass filled with ice. Make sure your coffee is completely cold.
  8. Using a spoon or small spatula, gently scoop the cold foam from the bowl and layer it generously over the top of your coffee. Serve immediately.

Notes

Make your cold foam right before pouring your coffee, as it holds its peak for about 15 minutes at most before starting to settle back into liquid milk. Whole milk and 2% milk create more stable foam than skim milk, but oat milk often produces superior texture for plant-based drinkers.
