Peanut Butter Baked Oatmeal | Kara Lydon

An easy make-ahead breakfast with less than 10 minutes prep time! This peanut butter baked oatmeal is made with rolled oats, cinnamon, peanut butter and is extra delicious when topped with chocolate chips.

Why I Love This Recipe

Peanut Butter Baked Oatmeal is the perfect make-ahead breakfast that can be prepped on a Sunday and enjoyed throughout the week, or even frozen to be enjoyed at a later date. 

Requiring less than 10 minutes of prep time and 45-55 minutes in the oven, it’s so easy to make and is beyond delicious. 

Peanut Butter Baked Oatmeal is loaded with ooey-gooey peanut butter and has a hearty texture that is warm and comforting. It’s made with rolled oats, chia seeds for a boost of fiber, and is filled with chocolate chips (plus more on top!). 

If you know me, you know I love baked oatmeal and if you’ve never made it before, you’re in for a treat. I highly recommend adding this to your breakfast routine to make weekday mornings easier.

Ingredients You’ll Need

Notes on Ingredients

butter: flavor enhancer

eggs: act to bind all of the ingredients together

maple syrup: provides some sweetness

vanilla: enhances the flavor and also gives a touch of sweetness

peanut butter: the star of the show! i used creamy, unsalted but use whichever variety you have on hand!

almond milk: I use almond milk for it’s mild, neutral taste but you can swap it with cow’s milk or your favorite non-dairy milk alternative

rolled oats: I like using rolled oats in baked oatmeal since they retain their texture well with baking. If you want to make a gluten-free version, be sure to grab certified gluten-free rolled oats. 

cinnamon: adds a bold, slightly sweet and warming flavor

baking powder: helps the oatmeal rise in the oven and contributes to the light, fluffy texture 

chia seeds: add a little bulk to the oatmeal and helps provide a creamy texture. Chia seeds also provide a boost of protein, fiber, and healthy fat

salt: essential flavor enhancer

chocolate chips: I use semi-sweet chocolate chips but you can substitute for dark chocolate chips, chocolate chunks, or any chopped up chocolate bar

Expert Tips

Recipe FAQs

Can you freeze baked oatmeal?

Yes, you can! To freeze Peanut Butter Baked Oatmeal first let it cool completely then I recommend cutting it into squares and placing the portions in an airtight container. If you want to take an extra step, you could wrap each portion in plastic wrap before putting it in the container. When ready to eat, you can pop it right on a microwave safe dish and in the microwave for about 1-2 minutes. 

What should I serve with baked oatmeal?

Peanut Butter Baked Oatmeal is delicious on its own, topped with a drizzle of peanut butter. For an extra boost of protein, you can also top it with Greek yogurt. Other topping ideas include whipped cream, maple syrup, honey, and a dash of cinnamon. 

Can I swap out the peanut butter?

Of course! Instead of peanut butter you can substitute almond butter, cashew butter, or any other nut butter of your choice. If you’re allergic to peanuts and tree nuts, you could also try using sunflower seed or pumpkin seed butter. 

Storage and Preparation

Peanut Butter Baked Oatmeal leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in microwave for 1-2 minutes with a little splash of almond milk or milk.

Baked oatmeal is also freezer-friendly. To store in the freezer, bake as directed, let cool completely, then store in an airtight container in the freezer for up to 3 months.
