Why it works

Matcha is powdered green tea, so you are eating the whole leaf rather than steeping it. Mixed into the base, it gives the oats a smooth, grassy flavour and a gentle lift of caffeine. Honey softens its natural bitterness, and coconut flakes add texture and a mellow sweetness that matcha gets on with.

Getting it smooth

Matcha clumps if you tip it straight into a thick base. Whisk it into a small splash of milk first until there are no lumps, then stir that into the jar. You want an even green, not green freckles.

Quality matters here

Better matcha is greener and sweeter. Cheaper matcha tends to be dull and bitter. If yours is on the bitter side, add a little more honey or use less powder.

Make it yours

Toast the coconut flakes for a nuttier taste. A few fresh berries on top add colour and tartness. Maple syrup can replace honey, and with the oat milk jar it becomes vegan. If you are making the base at home, soak rolled oats overnight in milk with chia and a few almonds, with the matcha whisked in.

Storage

Keeps covered in the fridge for a day. The colour dulls slightly over time, but the taste holds. One serving: around 510 calories, 15g protein and 11g fibre.
