FAQ

Can I customize the fruit or toppings?
Yes. Swap blackberries for other berries or add seeds, yogurt, or nut butter to taste.
Is this dairy-free? Can I use dairy-free kefir?
The recipe uses dairy kefir; you can substitute with dairy-free kefir or a plant-based kefir drink.
How long can I store overnight oats in the fridge?
Up to 2–3 days; stir before serving.
Are oats gluten-free?
Oats are naturally gluten-free but can be cross-contaminated during processing. Choose certified gluten-free oats if needed.
How many servings does this make? Can I scale the recipe?
It makes 2 servings; you can halve or double the ingredients.
What type of oats should I use?
Rolled oats work best for overnight oats; steel-cut oats take longer to soften.

Overnight (6+ hours) yields soft oats; a shorter soak (3–4 hours) will be firmer.
Can I warm it up and eat hot?
Yes, gently warm before serving if you prefer a hot breakfast.
Is there added sugar? How can I keep it balanced?
No added sugar in the recipe as written; natural sugars come from fruit and kefir. If needed, add a pinch of cinnamon or a drizzle of honey.

This looks like a nice make-ahead breakfast. I appreciate that it only needs a few simple ingredients and that you can just mix them in a jar the night before. The blackberries and walnuts should add a nice texture contrast. I would probably add a little sweetener, but it seems like a good base to customize.
