Slow Cooker Maple Brown Sugar Oatmeal is one of my kids' all-time favorite flavors of oatmeal. This simple crockpot oatmeal recipe tastes just like classic Maple Brown Sugar Oatmeal packets--warming with a touch of brown sugar and rich with maple.
But when it comes to flavor and nutrition this slow cooker version of oatmeal beats those packs of maple brown sugar oatmeal hands down!
Full of fiber, rich in calcium, and made with less sugar, this is oatmeal you can feel good feeding your kids before they head to school. Or grab a bowl of this hearty crockpot oatmeal before you head out the door to work!
And given that this oatmeal is made with steel-cut oats and in the slow cooker overnight, it comes together just as easy as any packet of store-bought oatmeal. Which you have to love when a healthy breakfast is that easy to make!
Ingredients for Crock Pot Oatmeal
- Steel Cut Oats--Steel cuts oats are a must for this slow cooker oatmeal recipe. They cook perfectly overnight and become tender and soft, but not at all mushy, as regular oats would being cooked this length of time.
- Milk--Use any milk you like for this oatmeal recipe. I have used almond milk, coconut milk, and regular milk with delicious results.
- Water--You need to add water along with dairy of your choice to the oatmeal. This prevents the milk from burning/scorching on the bottom of the slow cooker.
- Maple Syrup--Pure maple syrup, not artificial maple syrup for the best flavor!
- Brown Sugar--Just a tad for to nod to the classic brown sugar flavor.
- Vanilla Extract--To bring out the sweetness in this crockpot oatmeal recipe.
- Cinnamon
- Salt--A dash of salt heightens the flavor of maple and brown sugar.
- Coconut Oil--For greasing the slow cooker (feel free to use butter or cooking spray instead). This will help with clean-up and prevent the oats from sticking to the crockpot.

Hi Gina! Thrilled to hear you enjoyed the oatmeal. Store the leftovers in an airtight container for 4-5 days. Reheat individual servings in the microwave for 1-2 minutes, adding milk of needed to thin.
