Butterfinger Blondies with Butterfinger Buttercream

These Butterfinger Blondies are outrageously good! They are even topped with Butterfinger Buttercream Frosting!

I’m waiting for the lazy days of summer to arrive.

Do you know where they are?

Because I am waiting for them.  I even have a bottle of wine to share with them.

Please tell me they are coming.


I am ready for the lounging and the sun tanning and magazine reading.  I am ready for all the lazy.


Having my kids home from school is wonderful…that’s what I am supposed to say, right?

Of course I dearly love my children, but they happen to be driving me a little bit crazy.

They don’t want to be lazy.  They want to be busy.

Busy going here, busy going there, busy asking me random questions, busy getting every toy in my house out, busy eating all the Ring Dings, busy arguing over who built the best Lego ship…just BUSY!

It took me an hour yesterday to unload the dishwasher because of all the busy-ness that was going on.

I am certain the amount of negotiating and mediating I have done since June I think makes me a judge.

…or maybe just a crazy lady.  Yes, that’s probably more accurate.

I mean look at the title to this post.

There has to be something wrong with me.

I dare you to find another treat that uses the word “Butter” 3 times in the title alone.

Butter, butter, butter…ANNND Butter.

Somethings don’t need anymore elaboration…

Butterfinger Blondies with Butterfinger Buttercream

Buttercream + Butterfingers = Delicious.

Yes, busy and crazy.

The end.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

Hi, I want to try making these, but was wondering how many regular size Butterfinger bars it would take? Any idea?


Hey Shelly, I have a batch of these in the oven right now! I was thinking of passing on the frosting, are they good without it? I tried the dough and it was real good, or does the frosting make it or break it? Thanks a lot, I love the recipes you post! I also love to bake.

I happen to have some Butterfingers in my freezer from halloween…Yumm.


These are absolutely amazing. I saw this recipe a few days after you posted it — and I’ve made them twice already. This recipe is going in the keeper file for sure!!


outstanding! i’m such a fan of the humble butterfinger, and you’re bringing it to center stage with this tasty recipe! so nice–all bar cookies should be frosted, no? 🙂


Boy, I don’t know how I missed this on Tidy Mom so am so glad you linked it up on Strut Your Stuff. If I see the word Butterfingers I am there. I have found a couple of other really good Butterfinger Cookie recipes on other blogs, and it looks as though I have found a third. I love blondies; they are so fast as easy. I wish I could reach through my computer screen and eat one right now. These will get made this week, and the recipe and link are going on my Friday Finds list. Thanks for… Read more »

These look delicious! I only recently tried my first blondie and I really liked them. I’ve never had butterfingers as I’m from England either but I think I can guess how good these taste 🙂


I have always loved butterfinger. This recipe is wonderful.

Is there any powder sugar in the frosting?


Butterfingers are my favorite. Saving these immediately 🙂


I can’t believe my eyes… I think I could inhale the entire pan!

Ah, I remember those lazy days of summer. Unfortunately those were back in high school. *sigh* Pass the butterfinger blondies.


I am LOVING your new design!!! And your recipe card is adorable.

Sweet-Tooth-Alert! I feel an attack is coming my way, right about NOW! I LOVE IT!!


These look fantastic! My butterfinger loving son is away at college, and I know he will love these. I’m going to the store right now! Thanks for a great post!!


Those cookies look delicious, but I am currently living without a functioning oven and counting the days till the new one arrives. As for when the lazy days of summer come… be patient. When your kids are grown and out of the house you will be able to do anything (or nothing) all day, and believe me, it’s heavenly! Thanks for sharing the recipe!


I love blondies, especially with butterfingers-my all time favorite candy bar! Love your new look!
