    How to Make Peanut Butter Blondies

    Here's how to make the best peanut butter blondies:

    1. Preheat oven to 350 degrees and grease a 8x8 baking dish.
    2. In a large bowl, cream together the brown sugar and butter.
    3. Add in the eggs, vanilla, and peanut butter - mix well.
    4. Once combined add in flour, baking powder, baking soda and salt until just combined - don’t over mix.
    5. Pour the batter into the greased 8x8 baking dish and bake for 35-45 minutes at 350 or until a toothpick comes out clean.

    Tips for Chewy Peanut Butter Blondies

    • Don’t overmix: Whatever you do, don’t overmix the ingredients at the last step. If you over mix, this can make the blondies too sticky or add too many air bubbles.
    • Tap the pan on the counter: Just in case, after you’ve leveled out the batter in the pan, give it a few taps on the counter in order to settle the batter and remove any air bubbles. 
    • Take the brownies out on time: Don’t overcook the blondies. As soon as a toothpick comes out clean after being stuck in the middle, remove them from the oven. Food continues to cook once removed from the oven so, don’t wait too long or your blondies will end up rock hard or burnt. 

    Peanut Butter Blondie Variations:

    Brown Sugar: I haven't tried substituting brown sugar for white sugar but I think it would work in this recipe

    Butter: Butter is essential to this recipe. We haven't tried it with dairy free butter.

    Egg Whites: We don't recommend substituting eggs, but you can read this article on Egg Substitutions for Baking if you need to substitute.

    Vanilla Extract: Helps to add flavor, we don't recommend substituting.

    Peanut Butter: Make sure to use creamy peanut butter. Do not use chunky peanut butter. It's best to not use all natural peanut butter. Skippy peanut butter works best in this recipe.

    All Purpose Flour: We don't recommend substituting the flour, but you can check out this article on Cake Flour vs. All-Purpose Flour or Substitutions for All-Purpose Flour

    Baking Powder: and baking soda are essential for this recipe. Do NOT substitute

    Add ins: You can add in ½ cup of chocolate chips or peanut butter chips. Chopped peanuts would also be delicious!

    Freezing: You can freeze peanut butter blondies for up to 3 months. Wrap the blondies individually in plastic wrap and store in an airtight container. Thaw completely before enjoying.

    Peanut Butter Blondies Recipe FAQ

    Blondies aren't always peanut butter based. Some blondies are just a cake/cookie like base with no added flavoring or nuts

    How do you add peanut butter to blondies?

    It's easy to add peanut butter to blondies! You can add peanut butter chips or follow a peanut butter blondies recipe - either will be delicious.

    Are blondies meant to be gooey in the middle?

    Blondies are meant to be gooey in the middle. They should be set, but not super firm.

    Why are my blondies not gooey?

    If your blondies are not gooey, they were over cooked. Make sure to take blondies out of the oven as soon as a cake tester comes out clean when inserted in the center of them.
