Ingredients You’ll Need
Simple, wholesome ingredients come together in this recipe, each playing a crucial role in creating the perfect balance of taste, texture, and warmth. Every component is carefully chosen to build layers of flavor that make this Slow Cooker Peanut Butter Apple Oatmeal Recipe absolutely irresistible.
- 1 cup steel-cut oats: These oats offer a satisfyingly chewy texture and nutty flavor that stand up beautifully to long cooking times.
- 1 ½ cups almond milk: Almond milk adds a subtle creaminess while keeping the dish light and dairy-free.
- 1 ½ cups water: Essential for cooking the oats to their perfect tender state without making the dish too heavy.
- 2 tablespoons peanut butter: This brings a rich and creamy depth to the oatmeal, infusing it with a delicious nutty aroma.
- 2 apples (such as Honeycrisp), diced: Fresh apples add a burst of natural sweetness and a pleasant soft texture as they cook down gently.
- 1 tablespoon brown sugar: Just enough to enhance sweetness and add a hint of caramel-like flavor.
- Pinch of salt: Balances the sweetness and intensifies the overall flavors.
- Additional peanut butter (optional): Perfect for drizzling on top for an extra layer of richness at serving.
- Dried fruit: Raisins, cranberries, or apricots make wonderful chewy, tart accents.
- Mixed nuts: Almonds, walnuts, or pecans add crunch and contrast beautifully with the creamy oatmeal.
How to Make Slow Cooker Peanut Butter Apple Oatmeal Recipe
Step 1: Prepare the Ingredients
Start by gathering your ingredients and dicing the apples into bite-sized pieces. Having everything ready before you start will make the process smooth and enjoyable.
Step 2: Combine the Base Ingredients
Place the steel-cut oats, almond milk, water, and peanut butter directly into your slow cooker. Stir well until the peanut butter is completely mixed in, creating a creamy base that will infuse every spoonful with nutty goodness.
Step 3: Add Apples and Sweetener
Next, fold in the diced apples, brown sugar, and a pinch of salt. The apples will gently soften during the long cook, imparting a natural sweetness that perfectly complements the peanut butter.
Step 4: Cook on Low or High
Cover the slow cooker and set it to cook on low for 7 to 8 hours if you want to wake up to a ready-made, warm breakfast. If timing is tight, you can cook on high for 3.5 to 4 hours. Either way, the oats will soak up all the flavors and become wonderfully tender and creamy.
Step 5: Serve and Garnish
Once cooked, give the oatmeal a good stir. Then, scoop it into bowls and add any optional toppings like extra peanut butter, dried fruit, or mixed nuts for wonderful texture and an added burst of flavor.

Make Ahead and Storage
Storing Leftovers
After enjoying this delicious Slow Cooker Peanut Butter Apple Oatmeal Recipe, store any leftovers in an airtight container in the refrigerator for up to 4 days. The oats will thicken as they cool—just add a splash of almond milk when reheating to bring back a creamy texture.
Freezing
You can also freeze individual portions in freezer-safe containers for up to 3 months. This is perfect for prepping breakfasts in advance and enjoying a quick, nutritious meal after busy mornings.
Reheating

FAQs
Can I use regular oats instead of steel-cut oats?
While steel-cut oats give the best texture for this recipe, you can use rolled oats for a creamier, softer result, but the cooking time will be shorter—keep an eye on them to avoid overcooking.
Is almond milk necessary or can I substitute it?
You can substitute almond milk with any milk or milk alternative you prefer, such as soy, oat, or regular dairy milk, depending on your taste and dietary needs.
Can I prepare this recipe without the slow cooker?
Yes! You can cook the oats on the stovetop by simmering everything gently for about 25-30 minutes. Stir frequently to prevent sticking and ensure creamy oatmeal.
What kind of peanut butter works best?
Natural peanut butter with minimal ingredients is ideal for the best flavor and texture, but smooth or crunchy varieties both work—just choose according to your preference.
How sweet is this oatmeal, and can I adjust the sweetness?
The brown sugar adds a balanced mild sweetness, but you can always reduce or increase it. Alternatively, natural sweeteners like maple syrup or honey can be used for a different flavor profile.
