I love breakfast…in fact I think it’s my favourite meal of the day.  I go to bed thinking about it, I really do.  Anyone else?  No?  Just me?  😉 But seriously there are just so many delicious recipe ideas for breakfast, from pancakes and french toast to savoury egg bakes, quiche, good old fashioned bacon and eggs, and our favourite, baked oatmeals.

Peanut Butter Baked Oatmeal

We especially love baked oatmeals. They are a warm and hearty breakfast that everyone gobbles up.  I also love the fact that I can get breakfast ready the night before, then all I have to do is put it in the oven first thing in the morning.  This makes my mornings sooooo easy, especially if we have a busy day ahead.  Love that!

You can serve this Peanut Butter Baked Oatmeal plain or with a little jam, or some table cream. The. Best. Seriously, anything with peanut butter is Heaven on Earth for me. An open jar of peanut butter with a spoon…that’s just pure evil temptation. Peanut butter for breakfast = yum.

Peanut Butter Baked Oatmeal

Assemble all of the ingredients for this Peanut Butter Baked Oatmeal the night before and pop it in the oven in the morning for a warm and delicious breakfast!


  • 1 cup milk
  • 2 tbsp butter (melted)
  • 2 eggs
  • 2 tsp vanilla
  • 1/2 cup peanut butter
  • 1/2 cup brown sugar
  • 2 tsp baking powder
  • 3/4 tsp salt
  • 3 cups quick cooking oats


  1. In a bowl, combine the milk, melted butter, eggs, vanilla, peanut butter and brown sugar. I like to use a small hand blender to make sure the mixture is smooth and creamy. Set aside.
  2. In a separate bowl, combine the baking powder, salt and oats.
  3. Add the oat mixture to the milk mixture and mix well.
  4. Pour the batter into an 8×8 glass dish.
  5. To bake it right away, preheat your oven to 350 degrees, then bake the oatmeal for 25-30 minutes.
  6. For overnight oatmeal, just cover the dish and refrigerate overnight. In the morning, take it out of the fridge, preheat your oven to 350 degrees and bake it for 30-40 minutes.

  1. UMMM…this sounds sooo good. I am not a fan of quick cook oats…wonder if the old fashioned ones would work..?
    Can’t wait to try this…

    1. I’m not sure…I think they would, but you would likely have to add more liquid. I might try this variation! Let me know if you make it with the old fashioned ones, and how it turns out! Happy eating! 😉

    1. Hi Bonny! I don’t think so just because of the raw egg. But if you make it the night before it’s ready to throw in the oven first thing in the morning!

  2. I am a huge fan of baked oatmeal also! It’s like having cookies for breakfast, isn’t it??? I cannot wait to try this recipe. I may throw some chocolate chips in it for good measure. ;o)

  3. Hi! This recipe looks yummy! I love anything with oats or pb!
    I was wondering if you used baking powder or baking soda? In the ingredient list it says powder, but the directions say soda…I am about to make them, and don’t want to get it wrong 🙂
    Also, I was thinking of putting them in a muffin pan so the portions are already done, your thoughts?

  4. Oh.my.gosh. This sounds like heaven! I have never tried anything like this before….I know what we are having tomorrow! The side serving of jam is next level…

  5. Just made this for my family this morning and we loved it – especially my picky eater. Like eating a warm bowl of oatmeal, combined with a peanut butter cookie. Yum! Thanks for the recipe.

  6. 5 stars
    This was so good! We had it this morning with some maple syrup drizzled on top. I will definitely make it again.
