If you put a bag of peanut butter cups in front of me, you’re just asking for trouble. But if you give me the white chocolate peanut butter cups, well you can forget about ever seeing them again. As much as I LOVE chocolate, white chocolate is my all time favorite and the one thing I just can’t resist. So I just had to combine two of my favorite sweet treats ever: white chocolate peanut butter cups and blondies. Of course you know I just couldn’t resist throwing in more sweet goodness in the form of peanut butter chips. Oh my stars was I in blondie heaven when I took a bite of this gooey and additive dessert. If you’ve never had blondies, you’re missing out and I suggest (no I demand actually) that you make these asap, devour one in a corner and don’t share.
First sift together 1 cup all purpose flour, 1/2 teaspoon baking powder, 1/4 teaspoon kosher salt and 1/8 teaspoon baking soda. Set aside.
And of course you’ll need white chocolate peanut butter cups! 8 peanut butter cups! Mmmm.
Take 5 of the peanut butter cups and chop them each into 6 pieces. These will go in the batter. Take the other 3 peanut butter cups and chop them into 4 pieces. You’ll press these on top of the blondies at the very end when they’re baking.
In a bowl of a stand mixer with the paddle attachment, mix together 1 cup packed light brown sugar, 1/3 cup melted unsalted butter and 1 Tablespoon vanilla. Mix to combine.
Throw in 1 large egg at room temperature and mix until it’s incorporated.
Slowly and I mean slowly add in the dry ingredients. Mix until just combined. You don’t want to go all crazy with the mixing or you’ll end up with bricks and not blondies.
Fold the batter together with a spatula.
Throw in 2 Tablespoons of peanut butter chips. Oh my stars how I love these. I could eat the whole bag, seriously.
Add in the chopped white chocolate peanut butter cups (5 of them) and fold them in.
Ok I could stop right here and be happy. There’s nothing more delicious than blondie batter.
Spread it out into an 8 by 8 inch baking pan. It will seem like there isn’t much batter but don’t worry!
Bake at 350 degrees F for 20 minutes. After 20 minutes, press the remaining chopped up white chocolate peanut butter cups (3 of them) on top of the blondies. Bake for another 5 minutes. (total baking time = 25 minutes)
White Chocolate Peanut Butter Cup Blondies
1 cup all purpose flour
1/2 teaspoon baking powder
1/4 teaspoon kosher salt
1/8 teaspoon baking soda
1 cup packed light brown sugar
1/3 cup unsalted butter, melted
1 Tablespoon vanilla extract
1 large egg, at room temperature
2 Tablespoons peanut butter chips
8 White Chocolate Peanut Butter Cups (Five of them will each be cut into 6 pieces and folded into the batter. The other three will each be cut into 4 pieces and pressed on top of the blondies)
Sift the flour, baking powder, salt and baking soda into a bowl. Set aside.
In a bowl of a stand mixer with the paddle attachment, mix together the brown sugar, butter and vanilla. Mix for about 2 minutes.
Add in the egg and mix to incorporate it into the batter.
Slowly add in the dry ingredients and mix until almost combined.
Take a spatula and fold everything together.
Add in the peanut butter chips and fold them in.
Take 5 of the peanut butter cups and chop each one into 6 pieces. Throw them into the batter and fold them in.
Take the other 3 peanut butter cups and chop each one into 4 pieces. Set these aside.
Spread the batter into a lightly greased 8 by 8 inch baking pan. It will seem like there isn’t a lot of batter but don’t worry.
Bake the blondies at 350 degrees F for 20 minutes. Then press the remaining peanut butter cups on top of the blondies and bake for another 5 minutes. The total baking time is 25 minutes.
Cool the pan on a cooling rack and then cut into pieces. Enjoy!
















I don’t normally like white chocolate, but…these I could love!
These look wonderful, I absolutely love everything you post!!
Thank you Jess!
Yes, please! Look amazing!
Ooo yummy, I love white chocolate and peanut butter. It’s a good variation from milk chocolate and peanut butter.
I am so obsessed with white chocolate right now. These are getting made this weekend. At least if I have to deal with a hurricane I can eat delicious blondies.
You definitely deserve these if you have to deal with a hurricane! Stay safe
Yum! Those look amazing! I want!
The bars look great.
I am with you on loving white chocolate! These look delicious.
I don’t know how you do it my dear, but you manage to rock it every time I come onto your site. These would be a big hit with my white chocolate loving Daddy…I personally am not a big fan of white chocolate, but it sure is creative!
I don’t think I even knew white chocolate peanut butter cups existed!? This is fantastic news
These blondies look amazing.
I’m obsessed with anything peanut butter. These look A-mazing
You make the cutest stuff — definitely one of my favs popping up in Foodbuzz! Keep up the great work — these look amazing! Love the white chocolate cups!
Thank you so much!
These blondies look absolutely delicious!! Gorgeous pictures and great recipe!
Your food always makes me so hungry!
Ah, see we are quite different in terms of chocolate tastes; white chocolate is my least favorite variety because I feel it tastes less like chocolate.
Oh, my…white chocolate is my favorite, too…and these blondies with white chocolate Reeses look amazing! I think I’ll find an excuse to bake these beauties
Yes please!! Wow, this was a genius idea. Great pics!
I am with you on this, I find white chocolate more irresistible than chocolate, so I would have to try really hard to not eat the entire pan.
I did not know that white chocolate PB cups existed. L.O.V.E.!! Thanks for sharing Lindsey, sounds scrumptious!
I didn’t know they made white chocolate Reese’s. My stomach and I don’t agree with white chocolate (and personally I don’t like the taste) but wow. You learn something new everyday
I love white chocolate! Didn’t know so many people didn’t. Oh well. More for us
I love white chocolate peanut butter cups! These look so good
I’m not too big a fan of white chocolate, but oh my, do these look amazing!
I love some good white chocolate too! Yummmm!
I love blondies! Adding the white chocolate peanut butter cups is perfect!
I haven’t seen the white ones yet…YUMMY!
I’m the same way around peanut butter cups, although I think I’d be safe around the white chocolate ones, not a huge white chocolate fan. I think I’ll replace them with regular (or dark chocolate, ooo) and make them for myself!
I don’t discriminate. I’m sure I’ll love the white chocolate Reese’s as much as the milk chocolate ones. Adding them to a blondie? Priceless.
I don’t love the white chocolate peanut butter cups the way I love the dark chocolate ones but these blondies do look like they would be super hard to resist!
I can see why you were in blondie heaven. These sounds (and look) absolutely fantastic!
You had me at “white chocolate.” Those look delicious!
Yum Yum! I can see why they made the Foodbuzz Top 9.
My mouth was watering reading this, oh my does this sound amazing! Rich, decadent, sweet treat YUM! Hugs, Terra
For some reason white chocolate PB cups are never on my radar. Thanks for changing that! These look delicious and I love your site in general!
Wow. I am in awe at how incredible these look. They look so gooey and amazing. I LOVE white chocolate. Never would’ve thought to put it in a blondie. I haven’t made blondies before, but I think now is definitely the time. Thanks so much for sharing!
I just made these with reg pb cups (no white chocolate to be found at the local CVS). Can’t wait to dig in. Love your blog! xo
Wow, if only I could buy white chocolate Reese cups in Canada!
