Craving a sinfully rich, peanut buttery infused indulgence? Peanut Butter Butterscotch Blondies, with their fudge-like center and rich, peanuty taste (just like the perfect soft and chewy, peanut butter cookie) are about to become your new favorite dessert.

Blondies and peanut butter cookies just got a serious upgrade. That's because Peanut Butter Butterscotch Blondies blend all the best parts of both those delicious creations in one tiny, but mighty package.
Buttery crisp on the outside, but soft and chewy in the middle, each bite of these blondies is pure peanut butter blondie bliss. Added semisweet chocolate chips AND butterscotch morsels perfectly accent the blondies' already delicious, peanuty base with a rich, sweet flavor that's second to none.

🤔What is the difference between a blondie and a brownie?
I wish I could reveal something earth-shattering here, but it really is quite simple. Blondies are flavored with vanilla extract. Brownies are flavored with chocolate. When baked right, both have crispy edges and soft and chewy, slightly fudgy centers. And although blondies allegedly don't have more fun than brownies, YOU may have more fun when you eat them! |
🥘Ingredients
For a complete list with measurements, see the printable recipe card below
- butter- you can't have a rich blondie without this ingredient!
- smooth peanut butter- I use Jif
- light brown sugar- firmly packed; you can use dark brown for a deeper molasses flavor
- granulated sugar- for added sweetness
- eggs
- pure vanilla extract
- all-purpose flour- spoon into measuring cup and gently level off for best results
- baking powder & salt- leavening agents
- chocolate & butterscotch chips- because one is just no fun, and because both accent the peanut butter quite nicely
🔪Instructions
For more detailed instructions, see the printable recipe card below
- Use a hand mixer to blend softened butter and peanut butter.
- Next, add the brown and white sugars. Use the mixer on medium speed to blend well.
- Add eggs, one at a time, beating on low speed after each addition. Then add the vanilla. Mix on low speed until just blended.
- In a medium mixing bowl, mix the flour, baking powder and salt. Then add this mixture to the large bowl. Stir with a spoon until just combined.
- Stir in the butterscotch and chocolate chips. The mixture will be thick!
- Spread the mixture into a prepared 8x8 pan. (You may choose to line your pan with parchment paper first for easier removal.)
- Bake Peanut Butter Butterscotch Blondies in a 350 degree oven for 30-35 minutes.
Hint: When adding the dry ingredients and baking chips to the batter, stir until just combined. Over mixing will lead to very dense and thick blondies.

💭Top tip
Keep in mind that the longer Peanut Butter Butterscotch Blondies bake, the more cake-like they will be. We want them to be soft and chewy and fudge-like in the middle, but definitely not too gooey (which would be a sign of them being undercooked). I would advise checking in on the blondies a few times around the 30 minute mark (both before and after that time). Use a toothpick inserted in the center as your guide to determine if they are too gooey. If so, bake just a little longer and recheck!
🗨️FAQ
Technically yes, but only slightly gooey, with crisp edges. See the top tip above for more advice.
They should firm up, but not exactly harden. Make sure you store them in an airtight container. You can also include a slice of bread in the container to absorb extra moisture.
