This post brought to you by REESE’S® Brand. All opinions are 100% mine.

This blondie recipe is perfect for peanut butter lovers. It’s jam packed with rich, peanut butter goodness.

Do you all like peanut butter? I happen to love peanut butter — what’s not to love? And now that we know E is allergic to walnuts (but strangely not peanuts), I feel an odd urge to give her peanut butter even more often — kind of like…forget you walnuts, we’re having PEANUT butter.

Yeah…I have issues.

Update: Turns out N is allergic to tree nuts and peanuts. So…now we don’t have any of it. 

Scattered on marble countertop are blondies, Reese's pieces, and peanut butter cup minis.

I teamed up with Reese’s for a fun REESE’S® Baking Bracket Challenge. In the spirit of college basketball tournaments, the challenge was to create a game day recipe which was placed in a bracket in competition with other great recipes.

A bag of Reese's Minis and a bag of Reese's Pieces, side by side.

These rich and decadent blondies include mini REESE’S® Peanut Butter Cups as well as Reese’s Pieces for twice the peanut butter love.

This blondies recipe has quickly become a new favorite. They are moist, rich, and flavorful. Everything you want in a brownie’s buttery brown sugary sister. Next time I make them, I’m going to throw a scoop of cold vanilla ice cream on top of the hot blondie. Because…well…why not.

Even if you don’t have vanilla ice cream in your freezer (I never keep it in my freezer because if I did, I’d be eating it on a daily basis), blondies are phenomenal with a tall glass of ice cold milk or a steaming hot cup of coffee.

Still hungry?  Check out mint chocolate brownies, confetti cream cheese brownies, Kahlua brownies, black bean brownies, caramel kissed brownies, or potato chip brownies.

    I signed up for your blog recently and checked text instead of html not really knowing what I was doing and when I get your blog it is mostly filled with blue links. Should I have signed up for text so that I can get all of the recipes and pics without opening all of the links?? Just wondering.

      That’s strange! Html should be the version with photos and text not just links. You will have to click just one link to get to the recipe though. Hope that helps…

    I saw the recipe and played the bracket before reading your blog–this looks amazing!

    What’s really nice is going to Hershey and walking through Chocolate World–they have all kinds of chocolates and products they market all over the world. Yum!
