Why These Oats Are Different
Most overnight oat recipes are little more than oats soaked in milk — delicious, but not particularly filling. We’ve completely rethought the protein profile here by layering three sources of protein into every jar:
- Greek yogurt — adds creaminess and 10–12g of protein per ½ cup
- Vanilla protein powder — the main protein driver, adding 20–25g depending on your brand
- Chia seeds — 2g of plant-based protein plus 5g of fiber per tablespoon, which also helps the oats thicken to a perfect pudding-like consistency
Together, they create a breakfast that feels indulgent — creamy, sweet, berry-studded — but is genuinely one of the most nutritionally complete ways to start your day.
Use mason jars — 16oz wide-mouth jars are perfect. They stack neatly in the fridge, are easy to layer, and you can eat straight from the jar. No bowl, no extra dishes.
Ingredients (Makes 5 Jars)
Oat Base
- 2½ cups old-fashioned rolled oats (½ cup per jar)
- 2½ cups unsweetened almond milk (or any milk of choice)
- 1¼ cups plain Greek yogurt, 2% or full-fat (¼ cup per jar)
- 5 scoops vanilla protein powder (1 scoop per jar)
- 5 tbsp chia seeds (1 tbsp per jar)
- 2½ tbsp honey or maple syrup (½ tbsp per jar)
- 1 tsp vanilla extract (divided)
- Pinch of salt per jar
Toppings (Add Fresh Each Morning)
- Mixed berries — blueberries, raspberries, strawberries
- 1 tbsp natural almond or peanut butter
- 1 tsp honey drizzle
- Granola for crunch (optional)
- Sliced banana (day-of only)
Instructions
- Set up your jars. Line up 5 clean mason jars on your counter. This assembly-line approach makes Sunday prep fast and efficient.
- Mix the wet base. In a large mixing bowl or pitcher, whisk together the almond milk, Greek yogurt, protein powder, honey, and vanilla extract until the protein powder is fully dissolved and no lumps remain. This is easiest with a whisk or hand mixer.
- Add the dry ingredients. Add rolled oats and chia seeds to the bowl. Stir everything together until well combined. Let the mixture sit for 2 minutes — the chia seeds will start absorbing liquid and the whole mixture will thicken slightly.
- Divide between jars. Pour or ladle the oat mixture evenly into each jar (approximately 1 cup per jar). Seal with lids and refrigerate for a minimum of 6 hours, or overnight. The oats will thicken beautifully as they soak.
- Add toppings in the morning. When you’re ready to eat, give the oats a quick stir. If they’re thicker than you’d like, add a splash of milk and stir again. Top generously with fresh berries, a drizzle of nut butter, and any other toppings you like. Eat cold, or microwave uncovered for 90 seconds if you prefer warm oats.
The oats will keep in the fridge for up to 5 days. However, if you’re adding fruit inside the jar (not just on top), stick to berries — they hold up well. Avoid adding banana or apple inside the jar as they brown and turn mushy after day one.
Flavour Variations
Once you have the base formula down, the flavour possibilities are endless. Here are four of our most popular variations — all use the same oat base, just with different mix-ins and toppings:
| Flavour | Mix-in | Topping |
|---|---|---|
| Chocolate Peanut Butter | 1 tbsp cocoa powder + chocolate protein powder | Peanut butter + banana slices |
| Cinnamon Apple Pie | 1 tsp cinnamon + diced apple | Walnuts + maple syrup drizzle |
| Tropical Mango | ½ tsp coconut extract | Mango chunks + toasted coconut flakes |
| Strawberry Cheesecake | 1 oz cream cheese, softened | Sliced strawberries + graham cracker crumble |
Protein Powder Tips
Not all protein powders behave the same in overnight oats. Here’s what works best:
- Whey or casein protein — mixes smoothly and blends well with the yogurt. Vanilla or unflavoured are most versatile.
- Plant-based protein — works well but can make the texture slightly grainier. Add an extra splash of milk and blend before pouring into jars.
- Collagen peptides — dissolve completely and are flavourless. Great for a more subtle protein boost without changing the taste.

Frequently Asked Questions
Can I use instant oats instead of rolled oats?
You can, but the texture will be mushier. Rolled oats (old-fashioned oats) hold their shape better after soaking and give a more satisfying, chewy texture. Instant oats work in a pinch but are best if you’re only chilling for a few hours rather than overnight.
Can I make these without protein powder?
Absolutely. Omit the protein powder and increase Greek yogurt to ½ cup per jar. You’ll get around 18–20g of protein per serving — still a solid high-protein breakfast. You may also want to reduce the almond milk slightly since the powder normally absorbs some of the liquid.
Are overnight oats good for weight loss?
Yes — the combination of protein, fiber, and complex carbohydrates makes overnight oats one of the most satiating breakfasts you can eat, which helps reduce overall calorie intake throughout the day by keeping hunger at bay.
