With school starting next week, I’m feeling extra sentimental. Between the new season in our lives and the chaos in our home, I’ve had incredible cravings for my stress standby – peanut butter. I’m not sure why, but peanut butter always makes everything better.

Sweet and salty, smooth and creamy, it’s the perfect substitute for chocolate and in brownie form, you get the best of both worlds. I love serving peanut butter brownies al a mode – if they last long enough!

In fact, we should call these blondies as there is no chocolate in these sweet treats. They are flavored with vanilla and peanut butter takes the place of the traditional chocolate. They are gooey and cakey, and they really are a family favorite.

These peanut butter brownies are so amazing just out of the oven that we all rush for one. I hope these brownies save your day, too.

Peanut Butter Brownie Ingredients

You just need a few pantry staples to make these amazing brownies

  • Peanut Butter – I prefer to use smooth, but you can use crunchy. Please note natural peanut butter doesn’t work well. However, feel free to experiment with your own – learn how to make peanut butter here.
  • Butter – Unsalted butter, softened. You can get my tips to soften butter here.
  • Brown Sugar – The key ingredient to adding rich color and flavor.
  • White Granulated Sugar – Sweetens brownies to perfection.
  • Vanilla Extract – Pure is preferable over imitation.
  • Eggs
  • Baking Powder – Gives brownies a perfect rise.
  • Salt – Omit if you are using salted butter.
  • Flour – All purpose flour, no need to sift.

How to Make Peanut Butter Brownies

It takes no time at all to make a batch of these delicious treats!

  1. Prep – Preheat oven to 325 degrees F.
  2. Combine Sugars and Wet Ingredients – Cream peanut butter, butter sugars and vanilla. Beat in eggs.
  3. Combine Dry Ingredients – Add in baking powder, salt and flour, mix until smooth. Pour into greased 9×13 pan.
  4. Bake – Bake for 40-45 minutes.

Tips

  • To prevent the edges from browning, cover edges with foil.
  • For thicker brownies, bake for 30 minutes in an 8×8
  • Like my favorite skip the box brownies, I slightly under bake these.

What to Serve With Brownies

Obviously, these brownies are perfect on their own as a mid afternoon snack with a tea or coffee, but I also love serving them warm with some homemade ice cream. Try them with:

How to Store

  • Room Temperature – If you are not serving these brownies straight away, let them cool to room temperature and store in an airtight container. They will keep for about a week when stored at room temperature.
  • Refrigerator – There’s no need to refrigerate these brownies, as the moisture might affect texture.
  • Freezer – You can also freeze the baked brownies, don’t cut them, simply wrap the whole baking sheet in plastic wrap and foil and they will keep for up to 3 months.

    I baked mine at 325 for 30 mins in a 9X13 pan and wasn’t even close to being done. I turned the oven up to 350 and am now cooking it for 45 mins and still not done. I suggest you bake it at 350 degrees for 45-50 mins.

    Made it for my peanut butter obsessed dad and he loved them ! although I did have to cook it for about 45 minutes instead of 25 in a 9×13

  3. This is not a 9×9” pan recipe. I baked it for 60 min and was still unbaked at center. I should’ve followed my gut and put it in a 9×13” pan.

    1. I’m sorry for your experience, but all my recipes are tested 3 times and it is made in a 9×9. Internal oven temperatures, altitude and baking vessel material can also effect bake time. When in doubt, use the toothpick test.
