Why This Recipe Works (Quick Science)
Protein powder and Greek yogurt work together to increase the protein while making the oats creamy. Chia seeds soak up the liquid overnight and create a thick texture. The rolled oats slowly absorb the almond milk and coffee, making every bite soft without becoming mushy. Coffee adds rich flavor without adding much liquid, so the oats stay thick and satisfying.
Pro Tips
- Let the coffee cool completely before mixing so the yogurt stays smooth.
- Stir very well to break up any protein powder lumps.
- Wait until serving to add banana so it stays fresh.
- If the oats are too thick in the morning, stir in a splash of almond milk.
- Chill for at least 8 hours for the best texture.
Substitutions and Variations
- Use dairy milk instead of almond milk.
- Swap maple syrup for honey.
- Use chocolate protein powder for a mocha flavor.
- Add cocoa powder for richer chocolate taste.
- Top with berries instead of banana.
- Use walnuts or pecans instead of almonds.
Make Ahead Tips
