FAQs

What kind of oats should I use?

Use rolled oats (old-fashioned oats) for best texture. Steel-cut oats are not recommended because they don’t absorb the liquid as well and the texture won’t turn out right.

Can I use frozen blueberries instead of fresh?

Yes—frozen blueberries work well and will give the oats a fun purple hue once mixed in.

Can I make more than 2 servings at once?

Absolutely. Just scale up the ingredient amounts while maintaining the ratios, and divide into as many jars or containers as you need.

Can I use a different milk other than almond milk?

Yes—feel free to use dairy milk, soy milk, oat milk, or any milk of choice. The key is to use a liquid that works for you.

How sweet will this be?

Sweetness depends on your yogurt choice and maple syrup. If you use vanilla yogurt, you may need little to no added syrup. For plain yogurt, adjust the maple syrup (1–2 tablespoons) to your taste.

Can I skip the chia seeds?

You can—but chia seeds help thicken the mixture and add fiber and omega-3s. If omitted, the texture may be thinner.

Will the oats become soggy if stored for days?

They’ll thicken as they sit, and the texture may change slightly. Stir before eating, and if too thick, add a splash of milk to loosen. Stored properly, they’ll stay good up to about 5 days.

Can I add other toppings?

Yes—granola, nuts, coconut flakes, additional fruit, jam, or seeds all work well as toppings for extra texture and flavor.

Can I eat these cold or warm?

They’re designed to be eaten cold (straight from the fridge), but you can warm them up if you prefer—just heat gently and stir.

Can I make this completely sugar-free?

Yes. Omit the maple syrup and use plain unsweetened yogurt. You can also rely on the natural sweetness of the blueberries.
