Peanut Butter Baked Oatmeal

This peanut butter baked oatmeal is smooth, creamy, and extra delicious thanks to a generous scoop of peanut butter baked right in. Make it and enjoy easy breakfasts all week!

My baked oatmeal kick is still going strong, and this version has quickly earned a regular spot in my kitchen. The base is similar to my Blackberry Baked Oatmeal, but the peanut butter adds richness and that salty-sweet flavor that hits the spot. You can keep it simple or have a little fun with mix-ins like chocolate or fruit.

Why This Recipe Works

• Peanut butter adds richness and flavor while the protein and fat help keep you full longer
• It's a one-bowl recipe that the whole family will love.
• Totally customizable. Add chocolate for a classic flavor combo or go for PB&J vibes by adding fruit.

Ingredient Notes

Here's a few tips on some of the ingredients of this recipe. For full measurements, see the recipe card below:

• Old-fashioned oats - These give baked oatmeal its structure. Quick oats can turn gummy, and steel-cut oats won't soften properly.
• Maple syrup - Use the real stuff. It's flavor pairs so well with peanut butter!
• Milk - Whatever kind you have in the fridge. Almond milk, soy milk or oat milk can be used.
• Butter - Melted coconut oil can be used for a dairy-free option.
• Peanut butter - I prefer creamy peanut butter, but you could definitely use crunchy for some bits of peanuts throughout. Processed or all-natural will both work in this recipe.

Quick Tip: If using natural peanut butter, give it a good stir before measuring to avoid oily pockets in the oatmeal.

How to Make Peanut Butter Baked Oatmeal

This peanut butter baked oatmeal comes together quickly and doesn't require any special equipment.

Step 1: In a large bowl whisk together oats, baking powder, cinnamon & salt.

Step 2: Add milk, maple syrup, butter, peanut butter, eggs and vanilla extract to the dry ingredients. Whisk the mixture together thoroughly until everything is well combined.

For easy combining, I warm the peanut butter in the microwave until easy to pour and stir into the batter.

Step 3: This is optional, but at this point you can add chocolate chips or berries (strawberries, blueberries, raspberries or blackberries) to the oatmeal batter. Save a few to sprinkle on top.

Step 4: Pour batter into prepared baking dish sprayed with nonstick spray and top with remaining chocolate or berries. Bake at 350 for 40-45 minutes until the top is golden brown and center is set.

Step 5: Remove pan from the oven allow to sit for 10 minutes before slicing into squares.

Serving Tips

Cut the baked oatmeal into 9 squares and serve warm. This recipe is a great breakfast option that both kids & adults love.

It's delicious topped with:

• A drizzle of warmed peanut butter - add some to a small bowl and microwave for 15-30 seconds until runny enough to drizzle
• Maple syrup
• Greek yogurt or cottage cheese for extra protein
• Fresh fruit like strawberry or banana

It's filling on its own, but also works beautifully alongside fresh fruit or as part of a breakfast or brunch spread.

Storage & Reheating Tips

Leftover oatmeal is easy to pack for a snack or breakfast on-the-go for school or work.

Refrigerator:
Store in an airtight container for up to 5 days.

Freezer:
Cut oatmeal into squares and freeze for up to 3 months. Thaw a serving overnight in the fridge before reheating.

Reheating:
Microwave individual portions in 30-second intervals until warm.
