Fudge Frosted Peanut Butter Blondie Bars

Fudge Frosted Peanut Butter Blondie Bars - this frosting is OUTRAGEOUS!

You guys. I have done something major here. Like, put me down in the history books or something, because this is big.

I perfected chocolate frosting.

This stuff…oh. It’s divine. It’s so fudgy and rich and just plain perfect.

Fudge Frosted Peanut Butter Blondie Bars - this frosting is OUTRAGEOUS!

I really love fudgy chocolate frosting, but I’ve always struggled getting it just right. I don’t like cooca frosting recipes and I don’t have a ton of success with melted chocolate recipes. Then it hit me. If you want fudgy frosting, why not add hot fudge?

You may have noticed that I have an obsession with hot fudge? Hello, hot fudge banana bread, sundae cookie bars, hot fudge peanut butter bars, and hot fudge strawberry donut pudding.

Fudge Frosted Peanut Butter Blondie Bars - this frosting is OUTRAGEOUS!

Well, hot fudge is absolutely amazing in frosting. This recipe is super similar to the jars of frosting you can get by the cake mixes, without the weird after taste (am I the only one who notices the chemical aftertaste in pre-made baked stuff these days?) and you know exactly what is going into this recipe. Well, except for the hot fudge, but you could totally go homemade with the fudge ripple in this Peanut Butter Fudge Ice Cream recipe!

Anyway, I insist that y’all try this frosting! I slathered it on the most amazing peanut butter blondies ever! They just melt in your mouth!

    Oh my goodness these look good. I love chocolate and peanut butter. I cannot wait to try this chocolate frosting out. Lately I have had the worst cravings for chocolate at night. Yesterday I was dying for hot fudge sauce.
