Ingredients
- 200 grolled oats— 50 g per jar
- 600 gskyr or Greek yoghurt 0%— 150 g per jar
- 400 mlmilk— or a plant alternative
- 80 gvanilla protein powder— 20 g per jar; whey or plant-based
- 4 tsp (about 16 g)chia seeds
- 1 tspground cinnamon
- 320 gberries— 80 g per jar; frozen is ideal
How to make it
Whisk the protein powder into the milk first, on its own, until there is not a single lump left. Powder added to the thick mixture later will not dissolve — it clumps, and you find the clumps at breakfast.
Stir in the skyr, then the oats, chia seeds and cinnamon. The mix should look thick but pourable; if it does not, add a splash more milk.
Divide between four jars and press the surface flat so no dry oats sit above the liquid.
Add the berries as a top layer, or keep them separate and add them in the morning. Frozen berries are ideal added the night before — they thaw in the jar and bleed colour and juice into the oats.
Refrigerate for at least 4 hours, ideally overnight. Stir once before eating.
Keeps 4 days. Day one is firm and chewy, day four is soft and creamy — that is the oats absorbing liquid, not the jar going off. The berry layer sinks in a little from day two, which changes nothing but the look.

Variations
Chocolate peanut
Add 1 tablespoon of cocoa and 15 g of peanut butter per jar, and swap the berries for a sliced banana per jar. About 160 kcal and 7 g of fat more, and roughly 4 g more protein.
This version, per serving: ~613 kcal · 46 g protein · 77 g carbs · 15 g fat
Without protein powder
Use 200 g of skyr and 60 g of oats per jar instead. It still works, and the protein lands at roughly 33 g rather than 42 — worth knowing before you count it as a 40 g breakfast.

Coach's tip
42 g of protein before a morning session, with no hob and nothing to decide at 6 a.m. If you train early, eat it 60–90 minutes before you lift — oats and skyr sit heavier than a shake does. If you train later in the day, this works just as well as the breakfast after the session.
