I eat peanut butter by the spoonful. There. I said it. Please don’t judge. What’s more, sometimes I dip my spoonful of peanut butter into Reese’s Pieces peanut butter candies so it’s coated in candies when it goes in my mouth. Shocking, but true. I shared this passion with my younger sister, Kenzie, when we were kids and we laugh about it now but still indulge. If you love peanut butter like we love peanut butter, you will love this recipe – and probably wish you had grown up in our home. These rich and chewy peanut butter bars are packed with peanut butter chips, topped with a decadent layer of peanut butter, and sprinkled with Reese’s Pieces. Need I say more?

Peanut Butter Overload Bars

My Peanut Butter Overload Bars are inspired by the Disneyland Peanut Butter Blondies found in their Grand Californian Hotel. I was first introduced to these bars as a reader. Before I had a chance to try one, she actually brought me one – FROM CALIFORNIA – to my cake class! (I know, how nice is that!). The peanut butter blondie was so yummy, I had to recreate it!

In my version, however, I wanted a richer, more chewy flavor and texture in the center. To do that, I knew I needed to do a brown sugar base and lots of peanut butter!

The texture is so amazing and these bars are truly overflowing with peanut butter flavor.

What You Need for Peanut Butter Overload Bars

These peanut butter blondie bars are simply divine and require mostly ingredients you probably already have on hand.

  • All-purpose flour
  • Baking soda
  • Salt
  • Butter
  • Peanut butter
  • Brown sugar
  • Eggs
  • Vanilla extract
  • Reese’s peanut butter baking chips
  • Reese’s Pieces candy

NOTE: the brand of peanut butter baking chips makes a HUGE difference, in my opinion. The Reese’s brand is by far my favorite, with the best flavor and texture.

Can I make these bars ahead of time? Absolutely. Just keep them in an airtight container. They can be left at room temperature for a day or frozen to stay fresh for longer.

What if I don’t want as much peanut butter? If you want a little less peanut butter, swap the Reese’s for M&Ms. You could also do a chocolate ganache instead of a layer of peanut butter.
