Why it works
Breakfast and coffee usually arrive as two separate items. This merges them into one drink. Cold brew gives a smooth, low-bitterness coffee taste, chocolate protein and cocoa turn it mocha, and banana sweetens it without sugar. The soaked oats make it thick enough to count as a meal.
Cold brew or not
Cold brew is smoother and less acidic than hot coffee cooled down, which matters when it is the main liquid. If you only have regular coffee, brew it strong and let it cool fully before blending. Hot coffee in a blender is a lesson people learn once.
Getting the thickness right
Protein powder thickens as you blend, so add milk gradually. Frozen banana or a few ice cubes make it cold and shake-like. Blend until no oat flecks remain.
Make it yours
Swap the chocolate protein for vanilla and skip the cocoa for a latte-style version. A spoon of peanut butter makes it richer. Pick a vegetarian protein powder, plant-based for the vegan jar. Without a DIY Oats jar, soak rolled oats overnight in milk with chia and a few almonds, then blend.
When to drink it
Fresh, ideally. It is a full meal at around 637 calories, 41g protein and 16g fibre.
Questions people ask
- Can I use regular coffee instead of cold brew?
- Yes. Brew it strong and let it cool completely before blending. Cold brew is smoother, but regular coffee works.
- How much caffeine is in this smoothie?
- It depends on your coffee. Expect roughly what is in the amount of cold brew you pour in.
- Can I make it the night before?
- It is best fresh. Made ahead, it thickens and the coffee flavour flattens, so stir in a little milk before drinking.
