Why This Recipe Works (Quick Science)
Browning the butter changes its flavor—milk solids caramelize and create a nutty, deep aroma. When mixed with cinnamon and vanilla, it brings out warm, dessert-like notes. The oats soak overnight in almond milk, which softens them and breaks down starches, making them creamy without needing to cook.
Common Mistakes
- Using quick oats: They get too mushy. Stick with rolled oats.
- Skipping the brown butter step: Melted butter isn’t the same—brown it until golden and nutty.
- Not enough liquid: Oats won’t get soft without enough almond milk.
- Not chilling long enough: At least 6 hours for the best texture.
- Overloading with spices: A little cinnamon goes a long way.
What to Serve With
- Hot coffee or chai latte
- A side of fresh apple slices or banana
- A boiled egg for extra protein
- Sprinkle of chopped nuts on top
- Greek yogurt on the side

Make-Ahead Tips
Make 2–3 jars at once and store them in the fridge for breakfast all week. Don’t add fresh fruit until the morning you eat it to keep it fresh.
Instructions
Step 1: Brown the Butter
Add 1 tablespoon unsalted butter to a small saucepan. Melt over medium heat until it turns golden and smells nutty, about 3–5 minutes. Swirl the pan often and watch closely so it doesn’t burn.

Step 2: Mix the Base
In a small mixing bowl, combine 1/2 cup rolled oats, 1/2 cup almond milk, 1/4 teaspoon ground cinnamon, 1/2 teaspoon vanilla extract, and 1 tablespoon maple syrup. Stir to combine.

Step 3: Add Brown Butter
Pour the browned butter into the bowl with the oats mixture. Stir well until everything is combined and the oats are fully coated.

Step 4: Transfer and Chill
Spoon the mixture into a glass jar or container. Seal with a lid and place in the fridge overnight, or for at least 6 hours.

Step 5: Enjoy!
In the morning, take it out of the fridge. Stir and enjoy cold, or heat it in the microwave for 30 seconds. Optional: top with more maple syrup or cinnamon.

Leftovers and Storage Tips
Store in an airtight container or jar in the fridge for up to 4 days. You can eat them cold or heat them briefly in the microwave. Add fresh toppings right before eating.
