Start with the same base ratio
The equal starting amounts of oats and milk make the three versions easy to prepare together. Chia seeds and yogurt thicken the mixture further as it rests.
Treat the listed milk as a starting point. Different oat brands, yogurts, and mix-ins absorb liquid differently.
Stir all the way to the bottom
Chia seeds, honey, and peanut butter can collect at the bottom of the container. Scrape the bottom and corners while mixing so every spoonful thickens and tastes evenly.
Stir the oats again before serving. If you see a thick layer at the bottom, continue mixing until it is fully incorporated.
Adjust the texture after chilling
Do not judge the final thickness immediately after mixing. The oats and chia seeds need several hours to absorb the milk.
If the chilled oats are thicker than you like, stir in a small splash of milk. If they are too loose, add a little more chia seed or yogurt and refrigerate them again briefly.
Add fruit according to its texture
Firm fruit such as apples can be added earlier, although it will soften during storage. Bananas and other easily browning fruit are better added shortly before serving.
Fresh toppings also provide contrast against the softened oats.
Reserve some nuts for the top
Nuts mixed into the oats absorb moisture and become softer. This can be enjoyable, but it will not give you the same crunch as freshly added nuts.
Mix some into the jar for flavor and reserve the rest for topping if you want both textures.
Loosen the peanut butter first
Thick peanut butter can be difficult to mix evenly. Stir it with a small amount of the milk first, then add the remaining ingredients.
You can also leave a few visible streaks of peanut butter if you prefer stronger pockets of flavor.
Leave room in the container
Use a container large enough to stir the oats without spilling. A 300-ml jar works for one serving, but avoid filling it completely to the rim.
A little extra space also leaves room for fruit, nuts, or another splash of milk before serving.
