Butterfinger Blondies are the best blondie recipe with chunks of Butterfinger mixed in. This is the perfect dessert for lovers of Butterfinger candy bars.

A good blondie recipe is buttery and sweet, and it has a nice, firm texture with a tender bite.  This is that kind of blondie recipe.  A good amount of Butterfinger candy bar chunks are swirled into these good blondies. 

I love making blondies because it’s pretty easy to add things to a blondie and create a new dessert.  Eat blondies by themselves, and they’re delicious.  Add chocolate chips, and you have a blondie recipe with a little chocolate added in.  Add Butterfinger (or another candy bar), and you have an even more decadent treat!

Butterfinger Blondies are a great blondie recipe to bake and bring to a potluck or serve at a party.  They’re always the first to go on the dessert table.  People really love Butterfingers!

What are Butterfingers?

A Butterfinger is a candy bar created in 1923 in Chicago, Illinois by Otto Schnering.  It has a crispy peanut butter core and is covered in chocolate. It’s a popular candy bar in the United States.

How many ounces are in a Butterfinger Candy Bar?

A traditional, full-sized Butterfinger Bar is 2.1-ounces.  You’ll need 4 full-size candy bars for this recipe (total of 8.4-ounces).  If you have fun size candy bars to work with, those are .74-ounces each.  You’d need about 11 1/2 fun size candy bars for this recipe if you’re using those.

How to crush Butterfinger candy bars:

Place Butterfingers in a zip baggie and crush with a mallet or by pressing with the back of a large spoon.  Alternately, you can chop them on a cutting board and they’ll fall apart into small pieces pretty easily.

I’m a sucker for recipes that utilize candy bars in one way or another. I’ve tried Milky Way Cake… it calls for 8 full-size Milky Way bars. I swear that cake weighs about 5 pounds (it’s awfully good though.) Hershey’s Perfectly Chocolate Cake is another keeper… just one of those recipes that always turns out, well… ‘perfect.’ My son made a Snicker’s Bar Pie for our County Fair. He won a blue ribbon with that decadent treat. And my absolute favorite Gelato recipe has chunks of Heath Bar swimming inside.

    I tried these and they were delicious! I brought them to work and they were a hit. I mention them in my blog and added a link to this page. Hope you don’t mind!

    I added 1 cup of chocolate chips to mine just to get a bit more of the chocolate kick and it worked out well.

    Also another trick I’ve used (and seen around the web) is to line your baking pan with non-stick foil for easy removal (and it works!), if you don’t have non-stick foil handy I’ve also found that cooking spray with a generous amount of flour sprinkled over the top of it works as well.
