This blondie recipe is perfect for peanut butter lovers. It’s jammed 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 and 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.

However, turns out N is allergic to tree nuts and peanuts. So…now we have to be really careful about peanuts and peanut butter too.

I’m super excited to be teaming up with Reese’s for this fun REESE’S® Baking Bracket Challenge. In the spirit of college basketball tournaments, I was challenged to create a game day recipe which will be placed in a bracket in competition with other great recipes.

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 quickly became 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.

But 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), these would be phenomenal with a tall glass of ice cold milk or a steaming hot cup of coffee.
