Creamy Brown Sugar Overnight Oats
Ingredients
The Base
- ½ cup Old-fashioned rolled oats not instant
- ½ tbsp Chia seeds
- 1-2 tbsp Light brown sugar adjust to taste
- ½ cup Milk of choice dairy, almond, oat, or soy
- ¼ cup Plain Greek yogurt fat-free recommended for protein
Optional Toppings
- Extra brown sugar for sprinkling
- Fresh berries blueberries, strawberries
- Sliced banana
- Chopped nuts or almond butter
- Pinch of cinnamon
Instructions
- Combine Dry Ingredients: In a mason jar or airtight container, add the oats, chia seeds, and brown sugar. Give everything a quick stir to distribute the sugar evenly so every bite is sweet.
- Add Wet Ingredients: Pour in the milk and add the Greek yogurt. Stir thoroughly until the yogurt is fully incorporated and the mixture looks smooth.
- Check Consistency: Ensure there are no dry pockets of oats at the bottom of the jar. The mixture will look liquidy/soupy at this stage—this is normal!
- Refrigerate: Cover tightly with a lid and refrigerate for at least 5 hours, though overnight (8–12 hours) is best for that perfect creamy texture.
- Serve: In the morning, stir the oats to redistribute the liquid. If they are too thick, add a splash of milk. Top with fruit, nuts, or a sprinkle of extra brown sugar and enjoy cold or warmed up.
Notes
- Storage: These stay fresh in the refrigerator for up to 5 days.
- Gluten-Free: Ensure you use certified gluten-free rolled oats if you have a gluten intolerance.
- Vegan Option: Use plant-based milk and a dairy-free yogurt alternative (like coconut or almond yogurt).
- Warm it up: If you prefer hot oatmeal, microwave the jar (remove the metal lid first!) for 30–60 seconds before eating.

Ingredients
Here is everything you need to pull this together. It’s a short list of pantry staples that packs a punch in the flavor department!

- ½ tablespoon chia seeds (crucial for that pudding-like consistency)
- 1-2 tablespoons light brown sugar (adjust based on your sweet tooth)

- ¼ cup plain Greek yogurt (stick to fat-free for an extra protein boost)
- Optional toppings: Extra brown sugar, fresh berries, sliced banana, diced apples, or chopped nuts

How to Make Brown Sugar Overnight Oats
Here are the steps to breakfast bliss. Get ready, because this is shockingly simple!
1. Combine the Dry Ingredients. Grab a mason jar, a medium bowl, or any airtight container you have on hand. Add ½ cup old-fashioned rolled oats, ½ tablespoon chia seeds, and 1-2 tablespoons of light brown sugar. Give everything a quick stir to distribute the sugar evenly. This step is crucial because it ensures that every single bite will have that sweet, caramel-like flavor rather than hitting a pocket of plain oats later.
2. Add the Wet Ingredients. Next, pour in ½ cup of your milk of choice and add ¼ cup of plain Greek yogurt. Using a spoon or a small whisk, stir everything together thoroughly. You want to mix until the yogurt is completely incorporated and the mixture looks smooth and creamy.
- (Pro-Tip: Make sure you dig the spoon into the corners of the jar so there are no dry pockets of oats hiding at the bottom!)
At this stage, the mixture will look quite liquid, almost soupy. Don’t panic! This is precisely how it should look. The oats and chia seeds require an extra liquid to absorb overnight, creating the glossy, decadent sauce texture we aim for.
3. Refrigerate and Rest. Cover your container tightly with a lid or plastic wrap. Please place it in the refrigerator for at least 5 hours. However, for the absolute best results, I recommend leaving it overnight (8-12 hours). During this time, the starch in the oats softens, and the chia seeds expand to create an excellent pudding-like consistency. It is a hands-off process where time does all the heavy lifting for you.
4. Finish & Serve The next morning, remove your brown sugar overnight oats from the refrigerator. Please give them a good stir to redistribute any liquid that may have settled to the bottom. Check the consistency here; if the oats seem too thick or dry for your preference, you can add a splash of milk and stir again until you reach your desired creaminess.
Finally, sprinkle a little extra brown sugar on top for added sweetness and a lovely textured crunch. Top with your favorite fresh fruit, I love blueberries or sliced bananas, and dig in! You can enjoy these cold straight from the fridge, which is perfectly refreshing, or pop them in the microwave for 30-60 seconds if you prefer a warm bowl.

Tips, Variations & Serving Suggestions
This recipe is a fantastic canvas for creativity. While the classic brown sugar oatmeal flavor profile is nostalgic and delicious on its own, here is how I like to switch things up to keep my meal prep breakfast ideas interesting.
- Texture adjustments: If you prefer a thinner consistency, increase the milk to ⅔ cup. For a thicker, doughier texture, add an extra teaspoon of chia seeds.
- Sweetener swaps: My personal preference is light brown sugar due to its molasses notes, but you can also use maple syrup or honey as alternatives. Please note that liquid sweeteners may make the mixture slightly thinner.
- Boost the protein: To make this a high-protein overnight oats recipe, you can stir in half a scoop of vanilla protein powder during step one. You may need to add an extra splash of milk to balance the absorption.
- Flavor twists: Try adding a pinch of cinnamon or nutmeg for brown sugar cinnamon oatmeal vibes. A drop of vanilla extract also adds a bakery-style aroma that is totally crave-worthy.
- Storage: These will stay fresh in the fridge for up to 5 days. I usually prep a batch on Sunday night, so I have breakfast sorted for the whole work week!

What to Serve With Overnight Oats
While a jar of brown sugar overnight oats is a filling meal on its own, it’s sometimes lovely to round out the breakfast table, especially on weekends.
- Hard-Boiled Eggs: Since the oats are sweet and creamy, I love pairing them with a savory protein source, such as hard-boiled or soft-boiled eggs. The saltiness provides a perfect contrast.
- Fresh Fruit Salad: A side of melon, pineapple, or citrus adds a zippy, vibrant acidity that cuts through the creaminess of the oats.
- Hot Coffee or Cold Brew: There is nothing better than the contrast of cold oats with a steaming mug of coffee. It’s the ultimate morning duo!
- Nut Butter Toast: If you are fueling up for a big workout, a slice of whole-grain toast with almond butter alongside your oats adds a nice crunch and healthy fats.
