And do I have the best hungry busting breakfast for you today!

It’s peanut buttery, soft and so delicious.
This dish would be fantastic for Mother’s Day brunch…

We absolutely love baked oatmeals in our house.  They are a warm and hearty breakfast that everyone gobbles up. And I also love the fact that I can get breakfast ready the night before.  This makes my mornings sooooo easy.  Gotta love that!

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
Save Recipe


  • 1 cup milk
  • 2 tablespoons butter, melted
  • 2 eggs
  • 2 teaspoons vanilla
  • 1/2 cup peanut butter
  • 1/2 cup brown sugar
  • 2 teaspoons baking powder
  • 3/4 teaspoon 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 8x8 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…

    • 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! 😉

  2. Im making this tomorrow morning.

    It looks like a cross between breakfast and dessert–my favorite.

  3. This sounds like something my kids would love for a fun breakfast! Thanks for sharing. I pinned it for you!

  4. Would this work to bake overnight in a crockpot? Maybe not with the raw egg.

    • 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!

  5. Yeumm! and beauteous photos too!

  6. Mmm, that looks yummy!! I’ll be pinning. =)

  8. 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)

  9. 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?
