Recipe Notes & Tips:
- Use fully cooled coffee: Hot or warm coffee can cause the protein powder to clump instead of dissolving smoothly.
- Stir thoroughly first: Mixing the protein powder into the coffee before adding ice helps create a smoother texture.
- Choose a fine protein powder: Finely ground protein powders dissolve more easily without needing a blender.
- Adjust sweetness to taste: Add more or less honey depending on how sweet you like your iced coffee.
- Serving Suggestions: Enjoy this protein iced coffee on its own or pair it with recipes like Vanilla Almond Granola, Fig Chia Pudding, or Zucchini Muffins for a balanced breakfast or snack.
How to Store:
Refrigerator: Store any leftover mixture (without ice) in a sealed jar or bottle for up to 24 hours. Shake or stir well before serving.
Freezer: Not recommended, as the texture can change and the protein powder may separate after thawing.
Make ahead: Brew and chill your coffee the night before so it's ready to mix in the morning for a quick grab-and-go drink.
Protein Iced Coffee FAQs:
Protein iced coffee can be mixed without a blender by stirring protein powder into fully cooled coffee until dissolved before adding ice and milk.
Protein powder can clump in iced coffee if the coffee is warm or if ice is added too early, which is why it is best to stir the powder into cooled coffee first.
Whey, plant based, or collagen protein powders can all work for protein iced coffee, though finely ground powders tend to dissolve more smoothly.
